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

Methods： A retrospective study was conducted to analyse the clinical data of 42 elderly patients who had been treated for femoral neck fracture with DHS in our department between June 2009 and November 2011. There were 21 males and 21 females with a mean age of 68.5 years （range 60-75 years）. According to the Garden Classification, there were 19 cases of type II, 21 cases of type III and 2 cases of type IV fractures. By the Singh In- dex Classification, there were 3 cases of level 2, 19 cases of level 3 and 20 cases of level 4 fractures. The Harris cri- terion, complications and function recovery after operation were analysed. Results： The average hospitalization time in 42 patients was 11.2 days （range 7-21 days）. All patients were followed up for 12-26 months （mean 18 months）. No lung infection, deep venous thrombosis or other complications occurred. Partial backing-out of the screws was found in 2 cases. The internal fixation device was with- drawn after fracture healing. Internal fixation cutting was found in 1 case, and he had a good recovery after total hip arthroplasty. The time for fracture healing ranged from 3-6 months （average 4.5 months）. According to Harris criteri- on, 15 cases were rated as excellent, 24 good, 2 fair and 1 poor. The Harris scale was significantly improved from 30.52＋2.71 preoperatively to 86.61＋2.53 at 6 months post- operatively （P〈0.05）. Conclusion： DHS, being minimal invasive, al- lowing early activity and weight-bearing, is advisable for treatment of elderly patients with femoral neck fracture. In addition, it can avoid complications seen in artificial joint replacement. It is especially suitable for patients with mild osteoporosis.展开更多

Meth...Objective: To explore the effects of intravenous inhalational anesthesia on the hemodynamic homeostasis as well as postoperative brain function and Th1/Th2 immunity in elderly patients with femoral neck fracture. Methods: A total of 176 elderly patients with femoral neck fracture who received hip replacement in our hospital between July 2016 and June 2017 were divided into the total intravenous anesthesia group (n=86) and the intravenous inhalational anesthesia group (n=90) according to the anesthesia solution. The differences in introperative hemodynamic parameter levels as well as postoperative brain function index and Th1/Th2 cytokine contents were compared between the two groups. Results: During operation, hemodynamic parameters MAP and HR levels in intravenous inhalational anesthesia group were lower than those in total intravenous anesthesia group. 24 h after operation, serum brain function indexes MBP, S100B and NSE contents in intravenous inhalational anesthesia group were lower than those in total intravenous anesthesia group;serum Th1 cytokines IFN-γand IL-2 contents were higher than those in total intravenous anaesthesia group whereas Th2 cytokines IL-4 and IL-13 contents were lower than those in total intravenous anesthesia group. Conclusion: The intravenous inhalational anesthesia can effectively stabilize the intraoperative hemodynamics and reduce the postoperative brain function and Th1/Th2 immune function injury in elderly patients with femoral neck fracture.展开更多

The mean observation period was 36 mo. The age, sex, body mass index(BMI), time from admission to surgery, length of hospitalization, outcome after discharge, walking ability, duration of surgery, blood loss and complications were compared. RESULTS: There was no significant difference in the age, sex, BMI, time from admission to surgery, length of hospitalization, outcome after discharge, duration of surgery and blood loss between the two groups. Two weeks after the operation, assistance was not necessary for walking in the hospital in 65.0% of the patients in the DAA group and in 33.3% in the PA group(P < 0.05). As for complications, fracture of the femoral greater trochanter developed in 1 patient in the DAA group and calcar crack and dislocation in 1 patient each in the PA group.CONCLUSION: DAA is an approach more useful for BHA for femoral neck fracture in elderly patients than total hip arthroplasty in terms of the early acquisition of walking ability.展开更多

Methods: This study retrospectively analyzed 60 elderly patients with unstable intertrochanteric fractures treated with PFNA and artificial femoral head replacement from 2015.06 to 2018.06, of which 34 were in the PFNA group (Group A) and 26 in the artificial femoral head replacement group (Group B). Statistical analysis of relevant surgical indicators such as surgical time, intraoperative blood loss, postoperative blood transfusion, postoperative time to landing, postoperative infection rate, hospital stay, number of secondary operations, postoperative VAS score, and postoperative Hip function score comparison. Results: All 60 patients were followed up for 1 - 24 months. Compared with the artificial femoral head replacement group, the operation time of PFNA group was shorter, the blood loss during operation was less, and the difference was statistically significant (P 0.05). Conclusion: The hip joint function and pain scores of the artificial femoral head replacement group in the early and follow-up periods are better than those of the PFNA group. The artificial femoral head replacement is more suitable for the treatment of elderly unstable intertrochanteric fractures.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 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 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Background：There is conflicting evidence as to whether the femoral head should be preserved or replaced in elderly patients with displaced intracapsular femoral neck fractures.In this article,we performed a systematic review and meta-analysis to compare the short-and long-term effectiveness of arthroplasty （AR） and internal fixation （IF）.Methods：PubMed,Embase,and the Cochrane Library were searched systematically up to January 2016.All randomized controlled trials directly comparing the effectiveness of AR and IF for displaced intracapsular fracture were retrieved with no limitation on language or publication year.Results：In total,eight prospective randomized studies involving 2206 patients were included.The results of our study showed that patients in the AR group reported significantly lower complication （risk ratio：0.56,95% confidence interval [CI] =0.38-0.80）,re-operation （risk ratio：0.17,95% CI =0.13-0.22）,revision rates （risk ratio：0.11,95% CI：0.08-0.16）,and better function compared with their IF counterparts,and they were less likely to suffer postoperative pain.No statistically significant differences for the rates of mortality,infection,and/or deep vein thrombosis between AR and IF were found.Conclusions：Based on our analysis,we recommend that AR should be used as the primary treatment for displaced intracapsular femoral neck fractures in the elderly.However,IF may be appropriate for those who are very frail.
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[Abstract] Objective： To discuss the indications, surgical procedures, and curative effect of dynamic hip screw （DHS） in the treatment of femoral neck fracture in the elderly. Methods： A retrospective study was conducted to analyse the clinical data of 42 elderly patients who had been treated for femoral neck fracture with DHS in our department between June 2009 and November 2011. There were 21 males and 21 females with a mean age of 68.5 years （range 60-75 years）. According to the Garden Classification, there were 19 cases of type II, 21 cases of type III and 2 cases of type IV fractures. By the Singh In- dex Classification, there were 3 cases of level 2, 19 cases of level 3 and 20 cases of level 4 fractures. The Harris cri- terion, complications and function recovery after operation were analysed. Results： The average hospitalization time in 42 patients was 11.2 days （range 7-21 days）. All patients were followed up for 12-26 months （mean 18 months）. No lung infection, deep venous thrombosis or other complications occurred. Partial backing-out of the screws was found in 2 cases. The internal fixation device was with- drawn after fracture healing. Internal fixation cutting was found in 1 case, and he had a good recovery after total hip arthroplasty. The time for fracture healing ranged from 3-6 months （average 4.5 months）. According to Harris criteri- on, 15 cases were rated as excellent, 24 good, 2 fair and 1 poor. The Harris scale was significantly improved from 30.52＋2.71 preoperatively to 86.61＋2.53 at 6 months post- operatively （P〈0.05）. Conclusion： DHS, being minimal invasive, al- lowing early activity and weight-bearing, is advisable for treatment of elderly patients with femoral neck fracture. In addition, it can avoid complications seen in artificial joint replacement. It is especially suitable for patients with mild osteoporosis.
文摘Objective: To explore the effects of intravenous inhalational anesthesia on the hemodynamic homeostasis as well as postoperative brain function and Th1/Th2 immunity in elderly patients with femoral neck fracture. Methods: A total of 176 elderly patients with femoral neck fracture who received hip replacement in our hospital between July 2016 and June 2017 were divided into the total intravenous anesthesia group (n=86) and the intravenous inhalational anesthesia group (n=90) according to the anesthesia solution. The differences in introperative hemodynamic parameter levels as well as postoperative brain function index and Th1/Th2 cytokine contents were compared between the two groups. Results: During operation, hemodynamic parameters MAP and HR levels in intravenous inhalational anesthesia group were lower than those in total intravenous anesthesia group. 24 h after operation, serum brain function indexes MBP, S100B and NSE contents in intravenous inhalational anesthesia group were lower than those in total intravenous anesthesia group;serum Th1 cytokines IFN-γand IL-2 contents were higher than those in total intravenous anaesthesia group whereas Th2 cytokines IL-4 and IL-13 contents were lower than those in total intravenous anesthesia group. Conclusion: The intravenous inhalational anesthesia can effectively stabilize the intraoperative hemodynamics and reduce the postoperative brain function and Th1/Th2 immune function injury in elderly patients with femoral neck fracture.
文摘Objective To discuss the postoperative curative effects of two surgical techniques of minimally invasive total hip arthroplasty (THA) using metal-on-metal largediameter and conventional diameter femoral head for the elderly patients
文摘Femoral neck fractures account for nearly half of all hip fractures with the vast majority occurring in elderly patients after simple falls.Currently there may be sufficient evidence to support the routine use of hip replacement surgery for low demand elderly patients in all but non-displaced and valgus impacted femoral neck fractures.However for the physiologically young patients,preservation of the natural hip anatomy and mechanics is a priority in management because of their high functional demands.The biomechanical challenges of femoral neck fixation and the vulnerability of the femoral head blood supply lead to a high incidence of non-union and osteonecrosis of the femoral head after internal fixation of displaced femoral neck fractures.Anatomic reduction and stable internal fixation are essentials in achieving the goals of treatment in this young patient population.Furthermore,other management variables such as surgical timing,the role of capsulotomy and the choice of implant for fixation remaincontroversial.This review will focus both on the demographics and injury profile of the young patient with femoral neck fractures and the current evidence behind the surgical management of these injuries as well as their major secondary complications.
文摘AIM: To evaluate whether walking ability recovers early after bipolar hemiarthroplasty(BHA) using a direct anterior approach.METHODS: Between 2008 and 2010, 81 patients with femoral neck fracture underwent BHA using the direct anterior approach(DAA) or the posterior approach(PA). The mean observation period was 36 mo. The age, sex, body mass index(BMI), time from admission to surgery, length of hospitalization, outcome after discharge, walking ability, duration of surgery, blood loss and complications were compared. RESULTS: There was no significant difference in the age, sex, BMI, time from admission to surgery, length of hospitalization, outcome after discharge, duration of surgery and blood loss between the two groups. Two weeks after the operation, assistance was not necessary for walking in the hospital in 65.0% of the patients in the DAA group and in 33.3% in the PA group(P < 0.05). As for complications, fracture of the femoral greater trochanter developed in 1 patient in the DAA group and calcar crack and dislocation in 1 patient each in the PA group.CONCLUSION: DAA is an approach more useful for BHA for femoral neck fracture in elderly patients than total hip arthroplasty in terms of the early acquisition of walking ability.
文摘BACKGROUND Simultaneous bilateral femoral neck fractures are relatively rare injuries.They are usually associated with underlying metabolic bone disorders or systemic diseases.Long-term use of narcotics and bisphosphonates can also result in similar fracture patterns;however,association of this fracture type with longterm use of antiepileptic drugs is not very common.Only one such case has been reported in the literature.This article describes the second.CASE REPORT We report a case of simultaneous displaced bilateral femoral neck fractures in a 50-year-old epileptic patient,who had taken phenytoin for the past 3 years.The fractures were a result of low-velocity injury following a fall from the bed.The fractures were managed with a bilateral hemi-replacement arthroplasty.Oral bisphosphonates were given to improve the bone quality in the post-operative period.The patient had a good post-operative outcome,that was sustained throughout the entire follow-up period of 1 year.CONCLUSION Antiepileptic drugs should be supplemented with bisphosphonates and vitamin D to improve bone quality and prevent fractures in epileptic patients.

文摘BACKGROUND Controversy remains around the available choices for the internal fixation of a femoral neck fracture.The femoral neck system(FNS)was developed in 2018 and has been widely applied since then as it can provide rigid fixation stability with less damage to the bone mass around the fracture.However,no systematic reviews and meta-analyses have investigated the efficacy of the FNS in comparison with that of traditional internal fixation in the treatment of femoral fractures.AIM To assess the efficacy of the FNS in comparison with that of cannulated compression screws(CCS)in the treatment of femoral fractures through systematic review and meta-analysis.METHODS Five electronic databases(PubMed,Embase,Cochrane Central Register of Controlled Trials,China National Knowledge Infrastructure,and Wanfang)were searched from the earliest publication date to December 31,2021.Reference Citation Analysis(https://www.referencecitationanalysis.com/)was used to check the results and further analyze the related articles.Controlled trials were included if the FNS was applied for the femoral neck fracture in adults and if it was compared with CCS for the achievement of internal fixation.The measurement outcomes included the required operation time,observed patient’s blood loss,extent of fracture healing,patient’s Harris Hip score(HHS)at the last follow-up,and records of any complications(such as failure of internal fixation,femoral neck shortness,avascular necrosis of the femoral head,and delayed union or nonunion).RESULTS Ten retrospective controlled studies(involving 711 participants)were included in this metaanalysis.The meta-analysis showed that compared with CCS,use of the FNS could not decrease the operation time[standardized mean difference(SMD):-0.38,95%confidence interval(CI):-0.98 to 0.22,P=0.21,I2=93%),but it could increase the intraoperative blood loss(SMD:0.59,95%CI:0.15 to 1.03,P=0.009,I2=81%).The pooled results also showed that compared with CCS,the FNS could better promote fracture healing(SMD:-0.97,95%CI:-1.65 to-0.30,P=0.005,I2=91%),improve the HHS at the last follow-up(SMD:0.76,95%CI:0.31 to 1.21,P=0.0009,I2=84%),and reduce the chances of developing femoral neck shortness(OR:0.29,95%CI:0.14 to 0.61,P=0.001,I2=0%)and delayed union or nonunion(OR:0.47,95%CI:0.30 to 0.73,P=0.001;I2=0%)in adult patients with femoral neck fractures.However,there was no statistically significant difference between the FNS and CCS in terms of failure of internal fixation(OR:0.49,95%CI:0.23 to 1.06,P=0.07,I2=0%)and avascular necrosis of the femoral head(OR:0.46,95%CI:0.20 to 1.10,P=0.08,I2=0%).CONCLUSION Compared with CCS,the FNS could decrease the chances of developing femoral neck shortness and delayed union or nonunion in adults with femoral neck fractures.Simultaneously,it could accelerate fracture healing and improve the HHS in these patients.
文摘BACKGROUND Femoral neck stress fractures are rarely encountered among young adults and are often associated with either repetitive excessive loading or underlying bone pathology.Preliminary research has indicated human immunodeficiency virus(HIV)/antiretroviral therapy(ART)as predisposing agents to osteopenia and osteoporosis related complications.We report a case of HIV/ART induced insufficiency fracture in a resource limited setting in Central India.Our aim is to increase awareness and promote screening of HIV/ART related osteopenia and osteoporosis in order to prevent catastrophic orthopaedic complications.CASE SUMMARY A 35-year-old HIV positive male presented with a stress fracture of left femoral neck.The patient was on ART and reported no comorbidities.He went on to be successfully managed surgically.However,during work-up osteopenia of the contralateral proximal femur was recognised using Singh’s Index.Six months post-op the patient presented with right-sided femoral-neck stress fracture.At this stage the patient was nonconcordant with ART and denied surgical fixation.CONCLUSION In the absence of co-morbidities,several mechanisms of HIV/antiretroviral therapy may have played a role in predisposing our patient towards such a presentation.We recommend routine screening all HIV-infected patients for osteopenia,especially in younger individuals.In low resource settings and district hospitals,pelvis radiograph&Singh’s index can be used for screening.
文摘Objective: To compare the clinical efficacy of artificial femoral head replacement and Proximal femoral nail antirotation (PFNA) in the treatment of unstable femoral intertrochanteric fractures in the elderly. Methods: This study retrospectively analyzed 60 elderly patients with unstable intertrochanteric fractures treated with PFNA and artificial femoral head replacement from 2015.06 to 2018.06, of which 34 were in the PFNA group (Group A) and 26 in the artificial femoral head replacement group (Group B). Statistical analysis of relevant surgical indicators such as surgical time, intraoperative blood loss, postoperative blood transfusion, postoperative time to landing, postoperative infection rate, hospital stay, number of secondary operations, postoperative VAS score, and postoperative Hip function score comparison. Results: All 60 patients were followed up for 1 - 24 months. Compared with the artificial femoral head replacement group, the operation time of PFNA group was shorter, the blood loss during operation was less, and the difference was statistically significant (P 0.05). Conclusion: The hip joint function and pain scores of the artificial femoral head replacement group in the early and follow-up periods are better than those of the PFNA group. The artificial femoral head replacement is more suitable for the treatment of elderly unstable intertrochanteric fractures.
文摘BACKGROUND Hemiarthroplasty is the most common treatment in elderly patients with displaced intra-capsular femoral neck fracture(FNF).Prosthetic joint infection(PJI)is one of the most feared and frequent complications post-surgery because of the frail health status of these patients and the need for fast track surgery.Therefore,priorities should lie in effective preventive strategies to mitigate this burden.AIM To determine how much the implementation of the routine use of antibioticloaded bone cement(ALBC)as a relatively easy-to-apply amendment to the surgical practice reduces the infection rate in our hemiarthroplasty cohort.METHODS We retrospectively assessed all demographic,health status and treatment-related data of our FNF patients undergoing cemented hemiarthroplasty in the period from 2011 to 2017;241 patients were further analyzed after exclusion of patients with cancer-related sequelae and those who died before the end of the 1-year observation period.The PJI rate as diagnosed on basis of the Musculoskeletal Infection Society(MSIS)criteria 2011 was determined for each included patient and compared in function of the bone cement used for hip stem fixation.Patients were split into a group receiving a plain bone cement in the period from January 2011 to June 2013(non-ALBC group)and into a group receiving an ALBC in the period July 2013 to December 2017(ALBC group).Data analysis was performed with statistical software.We further calculated the cost-efficacy of the implementation of routine use of ALBC in the second group balancing the inhospital infection related treatment costs with the extra costs of use of ALBC.RESULTS In total 241 FNF patients who received cemented hemiarthroplasty in the period from January 2011 to January 2017 were eligible for inclusion in this retrospective study.There were 8 PJI cases identified in the ALBC group among n=94 patients,whereas 28 PJI cases were observed in the non-ALBC group among n=147 patients.The statistical analysis showed an infection risk reduction of 55.3%(in particular due to the avoidance of chronic delayed infections)in the ALBC group(95%CI:6.2%-78.7%;P=0.0025).The cost-evaluation analysis demonstrated a considerable cost saving of 3.500€per patient,related to the implementation of routine use of ALBC in this group.CONCLUSION Use of ALBC is a potent infection preventive factor in FNF patients receiving cemented hemiarthroplasties.It was further found to be highly cost-effective.
