However whether it is superior to condylar blade fixation is not clear. This study aimed to determine which treatment has better clinical outcomes in older patients. Materials and Methods: A total of 86 patients over the age of 60 with unstable trochanteric fractures within the past 3 weeks, were included in this prospective study conducted from June 1, 2018, to May 31, 2021. All the intertrochanteric fractures were classified according to AO/OTA classification. Among them, 44 cases were treated with the Proximal Femoral Nail (PFNA2) with or without an augmentation screw, and 42 cases were treated with the Condylar Blade Plate. In addition, the operative time, intraoperative blood loss, intraoperative and postoperative blood transfusion, postoperative weight-bearing time, hospitalization time, Harris score of hip function, Kyle’s criteria and postoperative complications were compared between the two groups. Results: The mean duration of surgery for the PFN group was 66.8 minutes (on average), whereas for the condylar blade plate group, it was 99.30 minutes (on average). The PFNA2 group experienced less blood loss (average of 80 mL) compared to the condylar blade plate group (average of 120 mL). Union and partial weight-bearing occurred earlier in the PFNA2 group (14.1 weeks and 10.6 weeks, respectively) compared to the Condylar blade plate group (18.7 weeks and 15.8 weeks). In two patients from the PFNA2 group, screw backing out and varus collapse complications were encountered;however, these patients remained asymptomatic and did not require revision surgery. In two other patients, screw cut out and breakage of the nail at the helical screw hole leading to non-union of the proximal femur were observed during the nine-month follow-up, necessitating revision surgery with prosthetic replacement. Among the condylar blade plate group, three patients experienced complications, including blade breakage at the blade and plate junction. In two cases, the fracture united in varus, and in one case, the blade cut through, resulting in non-union of the femoral head, which required revision surgery. According to the Harris hip score and Kyle’s criteria, a good-excellent outcome was observed in 92.85% of cases in the PFNA2 group and 90.90% of cases in the condylar blade plate group. Conclusion: Both the Proximal Femoral Nail A2 and Condylar blade plate are effective implants for the treatment of unstable trochanteric fractures. The intramedullary implant promotes biological healing and allows for early ambulation with minimal complications. Similarly satisfactory restoration of anatomy and favorable radiological and functional results can be achieved with the biological fixation provided by the 95-degree condylar blade plate. However, the use of PFNA2 internal fixation technique has the advantage of less trauma in elderly patients than the 95-degree condylar blade plate.展开更多

Methods: Seventy-five patients admitted to our Department of Trauma Surgery from June 2022 to April 2024 who underwent rib fracture osteotomy and internal fixation were selected. According to the types of drainage tubes left in the patients after the operation, they were divided into the observation group (35 cases who were left with disposable grooved negative pressure drainage tubes) and the control group (40 cases who were left with closed silicone thoracic drainage tubes). Comparison of chest drainage, pain, postoperative complications, secondary chest penetration rate, drain placement time, hospitalization time, and treatment costs were compared between the two groups. Results: The total postoperative chest drainage volume of the observation group was less than that of the control group (P < 0.05);the degree of pain, the incidence of postoperative complications, and the rate of secondary chest puncture in the observation group were lower than that of the control group three days after the operation (P < 0.05);and the time of drain placement in the observation group was shorter than that of the control group (P < 0.05). Conclusion: The application of disposable grooved negative pressure drainage tubes in rib fracture incision and internal fixation can significantly improve patients’ postoperative pain and discomfort, reduce complications, lower the rate of secondary chest penetration, promote patients’ postoperative recovery, decrease the amount of postoperative chest drainage, and shorten the time of drain placement, which is worthy of clinical promotion and application.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

Despite considerable advancements in technology and techniques, there can still be complications in the healing of long bone fractures. Non-unions, delayed unions, and hardware failures are common complications observed in clinical practice following open reduction and internal fixation of fractures [1]. Potential causes of these adverse clinical effects may be disruptive to the periosteal and endosteal blood supply, stress shielding effects, and inadequate mechanical stability. The goal of the present study was to explore the effect of screw position on the fracture healing and formation of new bone tissue with mechanoregulatory algorithms in a computational model. An idealized poroelastic 3D finite element (FE) model of a femur with a 5 mm fracture gap, including a plate-screw construct was developed. Nineteen different plate-screw combinations, created by varying the number and position of screws within the plate, were created to identify a construct with the most favourable attributes for fracture healing. The first phase of the study evaluated constructs through mechanical stress analyses to identify those constructs with high loadsupport capability. The second phase of the study evaluated healing and bone formation with a biphasic mechanoregulatory algorithm to simulate tissue differentiation for fixation within selected constructs. The results of our analysis demonstrated a 4-screw symmetrical construct with the largest distance between screws to provide the most favourable balance of stability and optimized conditions to promote fracture healing.展开更多

文摘Objective: To explore the application value of disposable grooved negative pressure drainage tubes in rib fracture incision and internal fixation. Methods: Seventy-five patients admitted to our Department of Trauma Surgery from June 2022 to April 2024 who underwent rib fracture osteotomy and internal fixation were selected. According to the types of drainage tubes left in the patients after the operation, they were divided into the observation group (35 cases who were left with disposable grooved negative pressure drainage tubes) and the control group (40 cases who were left with closed silicone thoracic drainage tubes). Comparison of chest drainage, pain, postoperative complications, secondary chest penetration rate, drain placement time, hospitalization time, and treatment costs were compared between the two groups. Results: The total postoperative chest drainage volume of the observation group was less than that of the control group (P < 0.05);the degree of pain, the incidence of postoperative complications, and the rate of secondary chest puncture in the observation group were lower than that of the control group three days after the operation (P < 0.05);and the time of drain placement in the observation group was shorter than that of the control group (P < 0.05). Conclusion: The application of disposable grooved negative pressure drainage tubes in rib fracture incision and internal fixation can significantly improve patients’ postoperative pain and discomfort, reduce complications, lower the rate of secondary chest penetration, promote patients’ postoperative recovery, decrease the amount of postoperative chest drainage, and shorten the time of drain placement, which is worthy of clinical promotion and application.

Control group received the traditional intramedullary nail treatment, and study group received magnetic-guided intramedullary nail treatment. The differences in serum levels of bone metabolism indexes and inflammatory factors were compared between the two groups 48 h after surgery.Results: 48 h after surgery, serum bone formation indexes BGP, PⅠNP, PⅠCP and BAP levels of study group were higher than those of control group whereas bone resorption indexesβ-CTX, TRACP5b and NTX levels were lower than those of control group;serum inflammatory factors TGF-β, hs-CRP, IL-1β, IL-6 and IL-17 levels were lower than those of control group.Conclusion:Compared with traditional intramedullary nail therapy, magnetic-guided intramedullary nail fixation can more effectively balance the bone metabolism status and reduce the fracture end trauma in patients with femoral shaft fracture.
文摘Objective:To analyze the trauma and bone metabolism of magnetic navigation intramedullary nail and traditional intramedullary nail fixation treatment of femoral shaft fracture. Methods:58 patients with femoral shaft fracture treated in our hospital between December 2011 and December 2015 were divided into observation group and control group by random number table (n=29). Control group received conventional intramedullary nail fixation treatment, and observation group received magnetic navigation intramedullary nail fixation treatment. 24 h after surgery, blood coagulation indexes, enzymology indexes, bone metabolism indexes and angiogenesis indexes were determined;6 months after surgery, bone mineral density levels were determined. Results:24 h after surgery, peripheral blood thrombin time (TT), prothrombin time (PT), and activated partial thromboplastin time (APTT) levels of observation group were significantly higher than those of control group, and serum fibrinogen (FIB), D-Dimer (D-D), lactate dehydrogenase (LDH), creatine kinase (CK), creatine kinase isoenzyme (CKMB), glutamic oxalacetic transaminase (GOT), sex hormone-binding globulin type I (SHBG), collagen cross-linked carboxyl-terminal telopeptide (CTX) and deoxypyridinoline (DPD) content were lower than those of control group while bone gla protein (BGP), insulin-like growth factor (IGF-1), hypoxia-inducible factor-1α (HIF-α), angiogenin 1 (Ang-1), recombinant basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) content were higher than those of control group;6 months after surgery, fracture end bone mineral density (BMD) value of observation group was higher than that of control group. Conclusions:Magnetic navigation intramedullary nail treatment of femoral shaft fracture can more effectively reduce the surgical trauma, improve bone metabolism and increase bone mineral density.

文摘Pauwels’femoral neck fracture classification is based on the biomechanical principle that shear stress and varus force increase along more vertically oriented fractures,resulting in higher risk of fracture displacement and ultimately nonunion.This principle continues to guide construct selection for femoral neck fracture internal fixation and is the foundation for treating non-union with valgus osteotomy.However,with poor inter-and intra-rater reliability,dated treatment recommendations,and unreliable prognostic value,the Pauwels classification cannot be directly applied in its entirety to the management of femoral neck fractures in modern practice.
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 Vascular injury is a rare complication of femoral shaft fractures,and rupture of the deep femoral artery is more difficult to diagnose because of its anatomical location and symptoms.Despite its low incidence,deep femoral artery rupture can lead to life-threatening outcomes,such as compartment syndrome,making early identification and diagnosis critical.CASE SUMMARY A 45-year-old male patient was admitted to our hospital due to right lower limb trauma in a car accident,with complaints of severe pain and swelling on his right thigh.X-ray demonstrated a right femoral shaft fracture.During preparation for emergency surgery,his blood pressure and blood oxygen saturation dropped,and sensorimotor function was lost.Computed tomography angiography was performed immediately to confirm the diagnosis of rupture of the deep femoral artery and compartment syndrome,so fasciotomy and vacuum-assisted closure were performed.Rhabdomyolysis took place after the operation and the patient was treated with appropriate electrolyte correction and diuretic therapy.Twenty days after the fasciotomy,treatment with the Hoffman Type II External Fixation System was planned,but it was unable to be immobilized internally based on a new esophageal cancer diagnosis.We kept the external fixation for 1 year,and 3 years of follow-up showed improvement of the patient’s overall conditions and muscle strength.CONCLUSION For patients with thigh swelling,pain,anemia,and unstable vital signs,anterior femoral artery injury should be highly suspected.Once diagnosed,surgical treatment should be performed immediately and complications of artery rupture must be suspected and addressed in time.

文摘In this editorial,I present my comments on the article by Solarino et al.Conversion hip arthroplasty,which is an optional salvage procedure performed following unsuccessful fixation of intertrochanteric femur fractures in elderly pati-ents,entails more complex processes and higher rates of operative complications than primary arthroplasty.Hence,it is important to consider the appropriateness of the primary treatment choice,as well as the adequacy of nailing fixation for intertrochanteric fractures.This article briefly analyzes the possible factors contributing to the nailing failure of intertrochanteric fractures and attempts to find corresponding countermeasures to prevent fixation failures.It also analyzes the choice of treatment between nailing fixation and primary arthroplasty for intertrochanteric fractures.
文摘BACKGROUND Femoral shaft fracture is a commonly encountered orthopedic injury that can be treated operatively with a low overall delayed/nonunion rate.In the case of delayed union after antegrade or retrograde intramedullary nail fixation,fracture dynamization is often attempted first.Nonunion after dynamization has been shown to occur due to infection and other aseptic etiologies.We present a unique case of diaphyseal femoral shaft fracture nonunion after dynamization due to intramedullary cortical bone pedestal formation at the distal tip of the nail.CASE SUMMARY A 37-year-old male experienced a high-energy trauma to his left thigh after coming down hard during a motocross jump.Evaluation was consistent with an isolated,closed,left mid-shaft femur fracture.He was initially managed with reamed antegrade intramedullary nail fixation but had continued thigh pain.Radiographs at four months demonstrated no evidence of fracture union and failure of the distal locking screw,and dynamization by distal locking screw removal was performed.The patient continued to have pain eight months after the initial procedure and 4 mo after dynamization with serial radiographs continuing to demonstrate no evidence of fracture healing.The decision was made to proceed with exchange nailing for aseptic fracture nonunion.During the exchange procedure,an obstruction was encountered at the distal tip of the failed nail and was confirmed on magnified fluoroscopy to be a pedestal of cortical bone in the canal.The obstruction required further distal reaming.A longer and larger diameter exchange nail was placed without difficulty and without a distal locking screw to allow for dynamization at the fracture site.Post-operative radiographs showed proper fracture and hardware alignment.There was subsequently radiographic evidence of callus formation at one year with subsequent fracture consolidation and resolution of thigh pain at eighteen months.CONCLUSION The risk of fracture nonunion caused by intramedullary bone pedestal formation can be mitigated with the use of maximum length and diameter nails and close follow up.

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Plate and screw constructs are routinely used in the treatment of long bone fractures. Despite considerable advancements in technology and techniques, there can still be complications in the healing of long bone fractures. Non-unions, delayed unions, and hardware failures are common complications observed in clinical practice following open reduction and internal fixation of fractures [1]. Potential causes of these adverse clinical effects may be disruptive to the periosteal and endosteal blood supply, stress shielding effects, and inadequate mechanical stability. The goal of the present study was to explore the effect of screw position on the fracture healing and formation of new bone tissue with mechanoregulatory algorithms in a computational model. An idealized poroelastic 3D finite element (FE) model of a femur with a 5 mm fracture gap, including a plate-screw construct was developed. Nineteen different plate-screw combinations, created by varying the number and position of screws within the plate, were created to identify a construct with the most favourable attributes for fracture healing. The first phase of the study evaluated constructs through mechanical stress analyses to identify those constructs with high loadsupport capability. The second phase of the study evaluated healing and bone formation with a biphasic mechanoregulatory algorithm to simulate tissue differentiation for fixation within selected constructs. The results of our analysis demonstrated a 4-screw symmetrical construct with the largest distance between screws to provide the most favourable balance of stability and optimized conditions to promote fracture healing.
