However, an adequate osteosynthesis method has not been elucidated yet. This study investigated the displacement direction of the femoral head fragment and its effect on the bone using finite element method. A finite element model for CSFF was developed from CT image data of a patient with osteoporosis using Mechanical Finder (ver. 11). Subsequently, finite element analyses were performed on six osteosynthesis models under maximum load applied during walking. The compressive stresses, tensile stresses, and compressive strains of each model were examined. The results suggested that the compressive and tensile stress distributions were concentrated on the anterior side of the femoral neck. Compressive strain distribution in the femoral head and neck was concentrated in four areas: at the tip of the blade or lag screw, the anteroinferior side of the blade or lag screw near the fracture site, and the upper right and lower left near the junction of the blade or lag screw and nail. Thus, the distribution of both these stresses revealed that the femoral head fragment was prone to anterior and inferior displacement. Distribution of compressive strains revealed the direction of the stress exerted by the osteosynthetic implant on the bone. The same results were observed in all osteosynthetic implants;thus, the findings could lay the foundation for developing methods for placing osteosynthetic implants less prone to displacement and the osteosynthetic implants themselves. In particular, the study provides insight into the optimal treatment of CSFF.展开更多

In sickle cell patients, the hip is often subjected to aseptic necrosis. The authors report the case of the child NL, aged 5 years and 4 months in whom a fracture of the femoral neck classified Delbet 3 was found as well as his sickle cell status discovered and in whom treatment by surgical abstention was carried out with a favorable evolution. This association of factors of the femoral head necrosis or nonunion is unusual and confirms the osteogenetic potential of a child. However, monitoring is necessary because other anomalies may reveal themselves.展开更多

We hypothesized that, with a well-codified technique, the Watson Jones approach (WJA) without image intensifier nor traction table, can allow open reduction and internal fixation (ORIF) of PFF using Dynamic hip screw (DHS), with satisfactory outcome. Patients and methods: Forty one consecutive patients (mean age 59.5 ± 21.6 years, 61% males) who were followed in a Teaching Hospital for PFF treated by ORIF using the WJA and DHS from January 2016 to December 2020 were reassessed. The outcome measures were the quality of the reduction, the positioning of the implants, the tip-apex distance (TAD), the rate and delay of consolidation, the functional results using Postel Merle d’Aubigné (PMA) score, the rate of surgical site infection (SSI) and the overall mortality. Logistic regression was used to determine factors associated with mechanical failure. Results: The mean follow-up period was 33.8 ± 15.0 months. Fracture reduction was good in 31 (75.6%) cases and acceptable in 8(19.5%) cases. Implant position was fair to good in 37 (90.2%) patients. The mean TAD was 26.1 ± 3.9 mm. Three patients developed SSI. Consolidation was achieved in 38 (92.6%) patients. The functional results were good to excellent in 80.5% of patients. The overall mortality rate was 7.3%. There were an association between mechanical failure and osteoporosis (p = 0.04), fracture reduction (p = 0.003), and TAD (p = 0.025). In multivariate logistic regression, no independent factors were predictive of mechanical failure. Conclusion: This study shows that ORIF using DHS for PFF via the Watson-Jones approach without an image intensifier can give satisfactory anatomical and functional outcomes in low-resource settings. It provides and validates a reliable and reproducible technique that deserves to be diffused to surgeons in austere areas over the world.展开更多

Patients were immobilized in a cast for 5 wk and the nails were removed from 6 to 12 wk after surgery. Twenty-four cases were clinically and radiographically re-evaluated using the Flynn's scoring criteria, focusing on: Limb length discrepancy, rotational deformity, angulation, hip and knee range of motion(ROM), functional status, complications, and parent's satisfaction.RESULTS Sixteen males and eight females with a mean age of 3.2 years at the time of treatment were re-evaluated at an average follow-up of 58.9 mo. No cases of delayed union were observed. The mean limb lengthening was 0.3 cm. Four cases experienced limb lengthening greater than 1 cm and always minor than 2 cm. Twelve point five percent of the cases showed an angulation < 10°. Complete functional recovery(hip and knee ROM, ability to run and jump on the operated limb) occurred in 95.7% of cases. Complications included two cases of superficial infection of the TEN entry point, one case of refracture following a new trauma, and one TEN mobilization. According to the Flynn's scoring criteria, excellent results were obtained in 79.2% of patients and satisfactory results in the remaining 20.8%, with an average parent's satisfaction level of 9.1/10.CONCLUSION TEN is as a safe, mini-invasive and surgeon-friendly technique and, considering specific inclusion criteria, it represents a useful and efficacy option for the treatment of diaphyseal femoral fractures even in patients younger than six years of age.展开更多

However, technical difficulties and implant related complications have been described with this technique, thus we need more studies to address these issues. Our study aims to understand technical difficulties involved in proximal femoral nailing, and specifically analyses neck shaft angle at follow-up indicating varus collapse and also to compare results of stable and unstable fractures. Materials and Methods: In this study, patients who presented to the Orthopedic Unit of Dr. TMA Pai Hospital (An associated hospital of Manipal University, Manipal) with trochanteric fractures included and treated with proximal femoral nailing. The technical difficulties involved with surgical procedure and techniques adapted to overcome such difficulties were recorded. All patients were followed up for a period of 2 years and final outcome assessment included the number of shortening, neck shaft angle and harris hip score. Results: 41 patients (mean age 71) who underwent proximal femoral nailing from January 2004 to December 2009 were included in the study, 38 patients completed 2-year follow-up. The technical difficulties we faced were divided into 3 categories, difficulties in securing entry point and guide wire placement especially when greater trochanter and piriform fossa were gathered, reduction was lost while passing nail, and finally difficulties faced during placement of hip screws. In all except one, neck shaft angle of more than 130 degrees was achieved, and this was also maintained in the final follow-up (Mean 131.9 degrees). All fractures were united, with mean shortening of 2 mm. Conclusions: Although PFN is technically required, with a proper technique PFN gives excellent clinical results with almost negligible varus collapse even in unstable trochanteric fractures. Regarding the techniques, reaming the proximal part of femur adequately and observing the nail passage with image carefully are important in placing the nail correctly, while, placement of lag screw in the inferior part of neck in anterior posterior projection and central in lateral projection reduces risk of implant failure.展开更多

In each case there was concern regarding the fixation that could be achieved using the available anatomic distal femoral plates due to the size and bone quality of distal fragment. The design of the Proximal Humeral Internal Locking System(PHILOS) allows nine 3.5-mm locking screws to be placed over a small area in multiple directions. This allowed a greater number of fixation points to be achieved in the distal fragment. Clinical and radiological short-term follow-up(6-12 mo) has been satisfactory in both cases with no complications. We suggest the use of this implant for extremely distal femoral fractures arising in relation to the femoral component of a TKR.展开更多

Aim of the study: To compare the outcome of fixation of femoral shaft fracture by elastic nail with Spica cast. Patient and method: This prospective comparative study was carried out in Sulaimani Teaching Hospital, in the period from the 10<sup>th</sup> of December 2011 to the 10<sup>th</sup> of June 2012, for two groups of children whose ages were between 4 - 12 years (average 6.61 years), sustained traumatic femoral shaft fractures with follow-up period of about 6 months. The first group was consisting of 30 children treated by Elastic Intramedullary Nail, while the second group was consisted of 30 children treated by hip Spica. The selection was made on random bases. Results: Age range was between 4 - 12 years and showed male predominance in both groups with ratio of about 2:1 while fracture site showed predominance of the midshaft pattern in both groups. This study showed highly significant deference (P value of 0.001) between the two groups (Spica group of 3 days versus Nail group median of rate 4.5 days) in the admission period. Our sample showed shortening of about 2 cm in 2 case in the Nail group (6.7%) versus 6 cases (20%) in Spica group. We reported 4 cases of wound infection (13.3%) and 4 cases of pin site irritation (13.3%) in nail group. A higher rate of malunion was observed in the Spica group (10 cases more than 10° angulation in coronal plane) while the Nail group reported 2 case more than 10° in coronal plane. The mean operative time for Nail group was 55 minutes while in Spica group was 30 minutes. We reported shorter time to start mobilization and walking with support or independently in the nail group (weight bearing time 7.2 weeks) compared with the Spica casting group (weight bearing time 7.5 weeks). Conclusion: Elastic nail fixation yields better outcome for femoral shaft fracture in form of easier child handling, parent’s satisfaction, and maintaining acceptable fracture alignment.展开更多

Unfortunately, modern textbooks give varying angle and anatomic specifications between the classified fracture grades. This inconsistency is perpetuated in the literature, so that it is difficult to compare conclusions made by different authors. Pauwels himself left room for interpretation. He published two studies, one in 1935 and one in 1973, each including 3 diagrams. The 1935 version cited an angle of 8° representing the vector of static forces acting on the femoral head. The 1973 diagrams, however, cited an angle of 16° to represent dynamic forces, without changing the angle from horizontal. This already complex sche- me is complicated by the fact that it depends on other factors such as femoral neck shaft (CCD) angle, femoral neck and head diameter, and/or distance of the fracture from the center of the femoral head. The multitude of factors argues against a rigid classification based on fixed angles from horizontal. Pauwels himself did not establish fixed critical angles between the fracture grades. In his own explanation of the system, he placed more value on mechanical considerations such as compression stress, shear stress, tensile force, shearing force, and torque. We propose therefore a simplified version of the Pauwels Classification: Grade I for fractures impacted in valgus, Grade II for fractures without free torque, and Grade III for fractures with free torque.展开更多

文摘BACKGROUND Dislocation rates after hemiarthroplasty reportedly vary from 1%to 17%.This serious complication is associated with increased morbidity and mortality rates.Approaches to this surgery are still debated,with no consensus regarding the superiority of any single approach.AIM To compare early postoperative complications after implementing the direct anterior and posterior approaches(PL)for hip hemiarthroplasty after femoral neck fractures.METHODS This is a comparative,retrospective,single-center cohort study conducted at a university hospital.Between March 2008 and December 2018,273 patients(a total of 280 hips)underwent bipolar hemiarthroplasties(n=280)for displaced femoral neck fractures using either the PL(n=171)or the minimally invasive direct anterior approach(DAA)(n=109).The choice of approach was related to the surgeons’practices;the implant types were similar and unrelated to the approach.Dislocation rates and other complications were reviewed after a minimum followup of 6 mo.RESULTS Both treatment groups had similarly aged patients(mean age:82 years),sex ratios,patient body mass indexes,and patient comorbidities.Surgical data(surgery delay time,operative time,and blood loss volume)did not differ significantly between the groups.The 30 d mortality rate was higher in the PL group(9.9%)than in the DAA group(3.7%),but the difference was not statistically significant(P=0.052).Among the one-month survivors,a significantly higher rate of dislocation was observed in the PL group(14/154;9.1%)than in the DAA group(0/105;0%)(P=0.002).Of the 14 patients with dislocation,8 underwent revision surgery for recurrent instability(posterior group),and one of them had 2 additional procedures due to a deep infection.The rate of other complications(e.g.,perioperative and early postoperative periprosthetic fractures and infection-related complications)did not differ significantly between the groups.CONCLUSION These findings suggest that the DAA to bipolar hemiarthroplasty for patients with femoral neck fractures is associated with a lower dislocation rate(<1%)than the PL.
文摘BACKGROUND Hip fractures account for 23.8%of all fractures in patients over the age of 75 years.More than half of these patients are older than 80 years.Bipolar hemiarthroplasty(BHA)was established as an effective management option for these patients.Various approaches can be used for the BHA procedure.However,there is a high risk of postoperative dislocation.The conjoined tendon-preserving posterior(CPP)lateral approach was introduced to reduce postoperative dislocation rates.AIM To evaluate the effectiveness and safety of the CPP lateral approach for BHA in elderly patients.METHODS We retrospectively analyzed medical data from 80 patients with displaced femoral neck fractures who underwent BHA.The patients were followed up for at least 1 year.Among the 80 patients,57(71.3%)were female.The time to operation averaged 2.3 d(range:1-5 d).The mean age was 80.5 years(range:67-90 years),and the mean body mass index was 24.9 kg/m^(2)(range:17-36 kg/m^(2)).According to the Garden classification,42.5%of patients were typeⅢand 57.5%of patients were typeⅣ.Uncemented bipolar hip prostheses were used for all patients.Torn conjoined tendons,dislocations,and adverse complications during and after surgery were recorded.RESULTS The mean postoperative follow-up time was 15.3 months(range:12-18 months).The average surgery time was 52 min(range:40-70 min)with an average blood loss of 120 mL(range:80-320 mL).The transfusion rate was 10%(8 of 80 patients).The gemellus inferior was torn in 4 patients(5%),while it was difficult to identify in 2 patients(2.5%)during surgery.The posterior capsule was punctured by the fractured femoral neck in 3 patients,but the conjoined tendon and the piriformis tendon remained intact.No patients had stem varus greater than 3 degrees or femoral fracture.There were no patients with stem subsidence more than 5 mm at the last follow-up.No postoperative dislocations were observed throughout the follow-up period.No significance was found between preoperative and postoperative mean Health Service System scores(87.30±2.98 vs 86.10±6.10,t=1.89,P=0.063).CONCLUSION The CPP lateral approach can effectively reduce the incidence of postoperative dislocation without increasing perioperative complications.For surgeons familiar with the posterior lateral approach,there is no need for additional surgical instruments,and it does not increase surgical difficulty.
文摘The differences in complication rates between the direct anterior and posterior approaches for hemiarthroplasty in elderly patients with femoral neck fractures are not yet fully understood.Dislocation,a severe complication associated with increased mortality and often requiring additional surgery,may occur less frequently with the direct anterior approach compared to the posterior approach.Careful consideration of patient demographics is essential when planning the surgical approach.Future research in this area should focus on robust randomized controlled trials involving elderly patients recovering from femoral neck fractures.
文摘Coronal shear fractures of the femoral neck (CSFF) are the most challenging to treat among proximal femur fractures, directly affecting the life expectancy of patients with osteoporosis. However, an adequate osteosynthesis method has not been elucidated yet. This study investigated the displacement direction of the femoral head fragment and its effect on the bone using finite element method. A finite element model for CSFF was developed from CT image data of a patient with osteoporosis using Mechanical Finder (ver. 11). Subsequently, finite element analyses were performed on six osteosynthesis models under maximum load applied during walking. The compressive stresses, tensile stresses, and compressive strains of each model were examined. The results suggested that the compressive and tensile stress distributions were concentrated on the anterior side of the femoral neck. Compressive strain distribution in the femoral head and neck was concentrated in four areas: at the tip of the blade or lag screw, the anteroinferior side of the blade or lag screw near the fracture site, and the upper right and lower left near the junction of the blade or lag screw and nail. Thus, the distribution of both these stresses revealed that the femoral head fragment was prone to anterior and inferior displacement. Distribution of compressive strains revealed the direction of the stress exerted by the osteosynthetic implant on the bone. The same results were observed in all osteosynthetic implants;thus, the findings could lay the foundation for developing methods for placing osteosynthetic implants less prone to displacement and the osteosynthetic implants themselves. In particular, the study provides insight into the optimal treatment of CSFF.

文摘BACKGROUND This article presents a rare case of a complex hip fracture involving the ipsilateral femoral neck,trochanter,and femoral head,that was accompanied by hip dislocation.Currently,there is no established standard treatment method for this specific type of fracture.Therefore,it is crucial to comprehensively consider factors such as patient age,fracture type,and degree of displacement to achieve a successful outcome.CASE SUMMARY A 38-year-old man sustained a comminuted fracture of his right hip as a result of a car accident.The injuries included a fracture of the femoral head,a fracture of the femoral neck,an intertrochanteric fracture of the femur,and a posterior dislocation of the hip on the same side.We opted for a treatment approach combining the use of a proximal femoral locking plate,cannulated screws,and Kirschner wires.Following the surgery,we developed an individualized rehabil-itation program to restore patient limb function.CONCLUSION For this complex fracture,we selected appropriate internal fixation and for-mulated individualized rehabilitation,which ultimately achieved good results.
文摘BACKGROUND Sport-induced injuries particularly affect young,healthy,and active individuals.Running,a popular and accessible sport,can cause a wide range of injuries,including stress fractures.Stress fractures can occur during high-intensity training or competitions,especially among well-trained amateurs and professional athletes.Adequate diagnosis can be complicated by the typically young age,unremarkable medical history,and vital condition of the patient.Stress fractures present insidiously,and this is specifically the case with stress fractures of the femoral neck.Timely intervention is crucial to prevent progressive displacement,as this can damage the blood supply to the femoral head.CASE SUMMARY A 30-year-old male runner presented to our outpatient clinic with persistent pain 3 weeks after running a marathon.X-ray showed a complete lateral fracture of the left femoral neck,which was treated surgically with a dynamic hip screw.CONCLUSION It is essential for healthcare providers to be vigilant for the subtle symptoms of stress fractures to ensure timely treatment.Early recognition prevents com-plication and leads to a better prognosis.
文摘BACKGROUND Among the most frequent hip fractures are trochanteric fractures,which usually occur from low-energy trauma like minor falls,especially in older people with osteoporotic bones.AIM To evaluate the treatment efficacy of dynamic condylar screws(DCS)and proximal femoral nails(PFN)for unstable intertrochanteric fractures.METHODS To find pertinent randomized controlled trials and retrospective observational studies comparing PFN with DCS for the management of unstable femoral intertrochanteric fractures,a thorough search was carried out.For research studies published between January 1996 and April 2024,PubMed,EMBASE,Scopus,Web of Science,Cochrane Library,and Google Scholar were all searched.The complete texts of the papers were retrieved,vetted,and independently examined by two investigators.Disputes were settled by consensus,and any disagreements that persisted were arbitrated by a third author.RESULTS This study included six articles,comprising a total of 173 patients.Compared to the DCS,the PFN had a shorter operation time[mean difference(MD):-41.7 min,95%confidence interval(95%CI):-63.04 to-20.35,P=0.0001],higher success rates with closed reduction techniques[risk ratio(RR):34.05,95%CI:11.12-104.31,P<0.00001],and required less intraoperative blood transfusion(MD:-1.4 units,95%CI:-1.80 to-1.00,P<0.00001).Additionally,the PFN showed shorter fracture union time(MD:-6.92 wk,95%CI:-10.27 to-3.57,P<0.0001)and a lower incidence of reoperation(RR:0.37,95%CI:0.17-0.82,P=0.01).However,there was no discernible variation regarding hospital stay,implant-related complications,and infections.CONCLUSION Compared to DCS,PFN offers shorter operative times,reduces the blood transfusions requirements,achieves higher closed reduction success,enables faster fracture healing,and lowers reoperation incidence.
文摘This review aims to gain a deeper understanding of the psychological state of elderly patients with femoral fractures and provide more theoretical and practical support for clinical treatment and care.Through a literature analysis,we found that elderly patients with femoral fractures face various psychological issues such as anxiety,depression,sleep disorders,and social isolation.The application of systematic nursing interventions in clinical practice,including cognitivebehavioral therapy,mindfulness therapy,family therapy,art therapy,interpersonal therapy,emotion-focused therapy,and relaxation training,has yielded significant results.Systematic psychological interventions can improve the psychological state and quality of life of elderly patients with femoral fractures.Therefore,promoting the application and practice of systematic psychological interventions in the clinical care of elderly patients with fractures will provide more effective psychological services to a wider group of patients with fractures in the future.
文摘Femoral neck fracture is classically a traumatic pathology in the elderly but it can also occur in young people during a road traffic accident or occasionally when the femoral neck has been weakened by a pathological process. In sickle cell patients, the hip is often subjected to aseptic necrosis. The authors report the case of the child NL, aged 5 years and 4 months in whom a fracture of the femoral neck classified Delbet 3 was found as well as his sickle cell status discovered and in whom treatment by surgical abstention was carried out with a favorable evolution. This association of factors of the femoral head necrosis or nonunion is unusual and confirms the osteogenetic potential of a child. However, monitoring is necessary because other anomalies may reveal themselves.
文摘Introduction: Standard procedures for surgical fixation of proximal femoral fractures (PFF) require an image intensifier which in developing countries remains a luxury. We hypothesized that, with a well-codified technique, the Watson Jones approach (WJA) without image intensifier nor traction table, can allow open reduction and internal fixation (ORIF) of PFF using Dynamic hip screw (DHS), with satisfactory outcome. Patients and methods: Forty one consecutive patients (mean age 59.5 ± 21.6 years, 61% males) who were followed in a Teaching Hospital for PFF treated by ORIF using the WJA and DHS from January 2016 to December 2020 were reassessed. The outcome measures were the quality of the reduction, the positioning of the implants, the tip-apex distance (TAD), the rate and delay of consolidation, the functional results using Postel Merle d’Aubigné (PMA) score, the rate of surgical site infection (SSI) and the overall mortality. Logistic regression was used to determine factors associated with mechanical failure. Results: The mean follow-up period was 33.8 ± 15.0 months. Fracture reduction was good in 31 (75.6%) cases and acceptable in 8(19.5%) cases. Implant position was fair to good in 37 (90.2%) patients. The mean TAD was 26.1 ± 3.9 mm. Three patients developed SSI. Consolidation was achieved in 38 (92.6%) patients. The functional results were good to excellent in 80.5% of patients. The overall mortality rate was 7.3%. There were an association between mechanical failure and osteoporosis (p = 0.04), fracture reduction (p = 0.003), and TAD (p = 0.025). In multivariate logistic regression, no independent factors were predictive of mechanical failure. Conclusion: This study shows that ORIF using DHS for PFF via the Watson-Jones approach without an image intensifier can give satisfactory anatomical and functional outcomes in low-resource settings. It provides and validates a reliable and reproducible technique that deserves to be diffused to surgeons in austere areas over the world.
文摘BACKGROUND Older adults are at high risk of femoral neck fractures(FNFs).Elderly patients face and adapt to significant psychological burdens,resulting in different degrees of psychological stress response.Total hip replacement is the preferred treatment for FNF in elderly patients;however,some patients have poor postoperative prognoses,and the underlying mechanism is unknown.We speculated that the postoperative prognosis of elderly patients with FNF may be related to preoperative psychological stress.AIM To explore the relationship between preoperative psychological stress and the short-term prognosis of elderly patients with FNF.METHODS In this retrospective analysis,the baseline data,preoperative 90-item Symptom Checklist score,and Harris score within 6 months of surgery of 120 elderly patients with FNF who underwent total hip arthroplasty were collected.We analyzed the indicators of poor short-term postoperative prognosis and the ability of the indicators to predict poor prognosis and compared the correlation between the indicators and the Harris score.RESULTS Anxiety,depression,garden classification of FNF,cause of fracture,FNF reduction quality,and length of hospital stay were independent influencing factors for poor short-term postoperative prognoses in elderly patients with FNF(P<0.05).The areas under the curve for anxiety,depression,and length of hospital stay were 0.742,0.854,and 0.749,respectively.The sensitivities of anxiety,depression,garden classification of FNF,and prediction of the cause of fracture were 0.857,0.786,0.821,and 0.821,respectively.The specificities of depression,FNF quality reduction,and length of hospital stay were the highest at 0.880,0.783,and 0.761,respectively.Anxiety,depression,and somatization scores correlated moderately with Harris scores(r=-0.523,-0.625,and-0.554;all P<0.001).CONCLUSION Preoperative anxiety,depression,and somatization are correlated with poor short-term prognosis in elderly patients with FNF and warrant consideration.

文摘The atypical femoral fracture(AFF)has been attracting significant attention because of its increasing incidence;additionally,its treatment is challenging from biological and mechanical aspects.Although surgery is often required to manage complete AFFs,clear guidelines for the surgical treatment of AFFs are currently sparse.We reviewed and described the surgical treatment of AFFs and the surveillance of the contralateral femur.For complete AFFs,cephalomedullary intramedullary nailing spanning the entire length of the femur can be used.Various surgical techniques to overcome the femoral bowing common in AFFs include a lateral entry point,external rotation of the nail,and the use of a nail with a small radius of curvature,or a contralateral nail.In the case of a narrow medullary canal,severe femoral bowing,or pre-existing implants,plate fixation may be considered as an alternative.For incomplete AFFs,prophylactic fixation depends on several risk factors,such as a subtrochanteric location,presence of a radiolucent line,functional pain,and condition of the contralateral femur;the same surgical principles as those in complete AFFs can be applied.Finally,once AFF is diagnosed,clinicians should recognize the increased risk of contralateral AFFs,and close surveillance of the contralateral femur is recommended.
文摘AIM To report the clinical and radiographic results of titanium elastic nail(TEN) in diaphyseal femoral fractures of children below age of six years.METHODS A retrospective analysis of 27 diaphyseal femoral fractures in children younger than six years treated with TEN between 2005 and 2015 was conducted. Patients were immobilized in a cast for 5 wk and the nails were removed from 6 to 12 wk after surgery. Twenty-four cases were clinically and radiographically re-evaluated using the Flynn's scoring criteria, focusing on: Limb length discrepancy, rotational deformity, angulation, hip and knee range of motion(ROM), functional status, complications, and parent's satisfaction.RESULTS Sixteen males and eight females with a mean age of 3.2 years at the time of treatment were re-evaluated at an average follow-up of 58.9 mo. No cases of delayed union were observed. The mean limb lengthening was 0.3 cm. Four cases experienced limb lengthening greater than 1 cm and always minor than 2 cm. Twelve point five percent of the cases showed an angulation < 10°. Complete functional recovery(hip and knee ROM, ability to run and jump on the operated limb) occurred in 95.7% of cases. Complications included two cases of superficial infection of the TEN entry point, one case of refracture following a new trauma, and one TEN mobilization. According to the Flynn's scoring criteria, excellent results were obtained in 79.2% of patients and satisfactory results in the remaining 20.8%, with an average parent's satisfaction level of 9.1/10.CONCLUSION TEN is as a safe, mini-invasive and surgeon-friendly technique and, considering specific inclusion criteria, it represents a useful and efficacy option for the treatment of diaphyseal femoral fractures even in patients younger than six years of age.

文摘BACKGROUND Osteoporosis is a global disease affecting 6.6%of the total population.Osteoporosis complications include fractures,increased bone fragility,and reduced bone strength.The most commonly affected parts are the vertebral body,hip,and wrist.AIM To examine the effect of alendronate sodium combined with InterTan for osteoporotic femoral intertrochanteric fractures on bone and fracture recurrence METHODS In total,126 cases of osteoporotic femoral intertrochanteric fractures were selected and divided into two groups according to the 1:1 principle by the simple random method.They were admitted to the Department of Orthopedics,First Affiliated Hospital of Xingtai Medical College,from January 2018 to September 2020.The control group was treated with InterTan fixation combined with placebo,and the observation group with alendronate sodium based on InterTan fixation.Operation-related indicators,complications,and recurrent fractures were compared between the groups.Changes in bone metabolism markers,t value for hip bone mineral density,and Harris Hip Score were observed.RESULTS Operation time,intraoperative blood loss,postoperative ambulation time,and complications were compared between the groups,and no significant difference was found.The fracture healing time was significantly shorter in the observation group than in the control group.β-Collagen-specific sequence(β-CTX)and total aminoterminal propeptide of type I procollagen(T-PINP)in the control group at 3 mo after operation were compared with those before operation,and the difference was not significant.Six months after the operation,theβ-CTX level decreased and T-PINP level increased.β-CTX level at 3 and 6 mo in the observation group after operation was lower,and TPINP level was higher,than that before operation.Compared with the control group,T-PINP level of the observation group was significantly higher andβ-CTX level was significantly lower at 3 and 6 mo after operation.The t value of hip bone mineral density was compared in the control group before and 1 mo after operation,and significant difference was not found.Compared with the control group,the t value of hip bone mineral density in the observation group was significantly higher at 1,3,6,and 12 mo after operation.Compared with the control group,the Harris score of the observation group was significantly higher at 1,3,6,and 12 mo after operation.The recurrence rate of fractures in the observation group within 12 mo was 0.00%,which was significantly lower than 6.35%in the control group.CONCLUSION Alendronate sodium combined with InterTan in the treatment of osteoporotic femoral intertrochanteric fractures can increase bone mineral density,improve hip joint function,promote fracture healing,and reduce fracture recurrence.
文摘Background: Proximal femoral nailing in communited intertrochanteric fractures is increasingly becoming popular in view of superior biomechanics and prevention of varus collapse associated with Dynamic hip screw. However, technical difficulties and implant related complications have been described with this technique, thus we need more studies to address these issues. Our study aims to understand technical difficulties involved in proximal femoral nailing, and specifically analyses neck shaft angle at follow-up indicating varus collapse and also to compare results of stable and unstable fractures. Materials and Methods: In this study, patients who presented to the Orthopedic Unit of Dr. TMA Pai Hospital (An associated hospital of Manipal University, Manipal) with trochanteric fractures included and treated with proximal femoral nailing. The technical difficulties involved with surgical procedure and techniques adapted to overcome such difficulties were recorded. All patients were followed up for a period of 2 years and final outcome assessment included the number of shortening, neck shaft angle and harris hip score. Results: 41 patients (mean age 71) who underwent proximal femoral nailing from January 2004 to December 2009 were included in the study, 38 patients completed 2-year follow-up. The technical difficulties we faced were divided into 3 categories, difficulties in securing entry point and guide wire placement especially when greater trochanter and piriform fossa were gathered, reduction was lost while passing nail, and finally difficulties faced during placement of hip screws. In all except one, neck shaft angle of more than 130 degrees was achieved, and this was also maintained in the final follow-up (Mean 131.9 degrees). All fractures were united, with mean shortening of 2 mm. Conclusions: Although PFN is technically required, with a proper technique PFN gives excellent clinical results with almost negligible varus collapse even in unstable trochanteric fractures. Regarding the techniques, reaming the proximal part of femur adequately and observing the nail passage with image carefully are important in placing the nail correctly, while, placement of lag screw in the inferior part of neck in anterior posterior projection and central in lateral projection reduces risk of implant failure.
文摘We report two cases where a proximal humeral locking plate was used for the fixation of an extremely distal, type Ⅲ peri-prosthetic femoral fractures in relation to a total knee replacement(TKR). In each case there was concern regarding the fixation that could be achieved using the available anatomic distal femoral plates due to the size and bone quality of distal fragment. The design of the Proximal Humeral Internal Locking System(PHILOS) allows nine 3.5-mm locking screws to be placed over a small area in multiple directions. This allowed a greater number of fixation points to be achieved in the distal fragment. Clinical and radiological short-term follow-up(6-12 mo) has been satisfactory in both cases with no complications. We suggest the use of this implant for extremely distal femoral fractures arising in relation to the femoral component of a TKR.
文摘BACKGROUND Femoral head fractures(FHFs)are considered relatively uncommon injuries;however,open reduction and internal fixation is preferred for most displaced fractures.Several surgical approaches had been utilized with controversial results;surgical hip dislocation(SHD)is among these approaches,with the reputation of being demanding and leading to higher complication rates.AIM To determine the efficacy and safety of SHD in managing FHFs by reviewing the results reported in the literature.METHODS Major databases including PubMed,Embase,Web of Science,and Cochrane Central Register of Controlled Trials were searched to identify studies reporting on outcomes of SHD utilized as an approach in treating FHFs.We extracted basic studies data,surgery-related data,functional outcomes,radiological outcomes,and postoperative complications.We calculated the mean differences for continuous data with 95%confidence intervals for each outcome and the odds ratio with 95%confidence intervals for binary outcomes.P<0.05 was considered significant.RESULTS Our search retrieved nine studies meeting our inclusion criteria,with a total of 129 FHFs.The results of our analysis revealed that the average operation time was 123.74 min,while the average blood loss was 491.89 mL.After an average followup of 38.4 mo,a satisfactory clinical outcome was achieved in 85%of patients,ranged from 30%to 86%,with avascular necrosis,heterotopic ossification,and osteoarthritis being the most common complications occurring at an incidence of 12%,25%,and 16%,respectively.Trochanteric flip osteotomy nonunion and trochanteric bursitis as a unique complication of SHD occurred at an incidence of 3.4%and 3.8%,respectively.CONCLUSION The integration of SHD approach for dealing with FHFs offered acceptable functional and radiological outcomes with a wide range of safety in regards to the hip joint vascularity and the development of avascular necrosis,the formation of heterotopic ossification,and the development of posttraumatic osteoarthritis;however,it still carries its unique risk of trochanteric flip osteotomy nonunion and persistent lateral thigh pain.
文摘Introduction: Femoral shaft fractures are among the most common pediatric injury, which have the highest incidence among other pediatric fractures, and treatment of them carries a lot of controversies. Aim of the study: To compare the outcome of fixation of femoral shaft fracture by elastic nail with Spica cast. Patient and method: This prospective comparative study was carried out in Sulaimani Teaching Hospital, in the period from the 10<sup>th</sup> of December 2011 to the 10<sup>th</sup> of June 2012, for two groups of children whose ages were between 4 - 12 years (average 6.61 years), sustained traumatic femoral shaft fractures with follow-up period of about 6 months. The first group was consisting of 30 children treated by Elastic Intramedullary Nail, while the second group was consisted of 30 children treated by hip Spica. The selection was made on random bases. Results: Age range was between 4 - 12 years and showed male predominance in both groups with ratio of about 2:1 while fracture site showed predominance of the midshaft pattern in both groups. This study showed highly significant deference (P value of 0.001) between the two groups (Spica group of 3 days versus Nail group median of rate 4.5 days) in the admission period. Our sample showed shortening of about 2 cm in 2 case in the Nail group (6.7%) versus 6 cases (20%) in Spica group. We reported 4 cases of wound infection (13.3%) and 4 cases of pin site irritation (13.3%) in nail group. A higher rate of malunion was observed in the Spica group (10 cases more than 10° angulation in coronal plane) while the Nail group reported 2 case more than 10° in coronal plane. The mean operative time for Nail group was 55 minutes while in Spica group was 30 minutes. We reported shorter time to start mobilization and walking with support or independently in the nail group (weight bearing time 7.2 weeks) compared with the Spica casting group (weight bearing time 7.5 weeks). Conclusion: Elastic nail fixation yields better outcome for femoral shaft fracture in form of easier child handling, parent’s satisfaction, and maintaining acceptable fracture alignment.
文摘ABSTRACT The Pauwels Classification of femoral neck fractures, initially published in 1935, is used world-wide. Unfortunately, modern textbooks give varying angle and anatomic specifications between the classified fracture grades. This inconsistency is perpetuated in the literature, so that it is difficult to compare conclusions made by different authors. Pauwels himself left room for interpretation. He published two studies, one in 1935 and one in 1973, each including 3 diagrams. The 1935 version cited an angle of 8° representing the vector of static forces acting on the femoral head. The 1973 diagrams, however, cited an angle of 16° to represent dynamic forces, without changing the angle from horizontal. This already complex sche- me is complicated by the fact that it depends on other factors such as femoral neck shaft (CCD) angle, femoral neck and head diameter, and/or distance of the fracture from the center of the femoral head. The multitude of factors argues against a rigid classification based on fixed angles from horizontal. Pauwels himself did not establish fixed critical angles between the fracture grades. In his own explanation of the system, he placed more value on mechanical considerations such as compression stress, shear stress, tensile force, shearing force, and torque. We propose therefore a simplified version of the Pauwels Classification: Grade I for fractures impacted in valgus, Grade II for fractures without free torque, and Grade III for fractures with free torque.
