OBJECTIVE: Femoral neck fracture is considered a difficult fracture to treat and often gives rise to unsatisfactory treatment results. Cannulated cancellous screws (CCS) or a sliding hip screw (SHS) are the mainstream internal fixations used for osteosynthesis of femoral neck fractures. There is a need to integrate existing data through a meta-analysis to investigate the safety and effectiveness of CCS and SHS in the treatment of femoral neck fractures. METHOD: According to the Cochrane Handbook for Systematic Reviews of Interventions, we screened for the relevant studies by searching Google Scholar, the Cochrane Controlled Trials Register, the Cochrane Library, Web of Science, EMBASE, and PubMed...

BACKGROUND: Basicervical femur neck fracture (FNF) is a rare type of fracture, and is associated with increased risk of fixation failure due to its inherent instability. The purpose of this study was (1) to investigate the incidence of fixation failure and (2) to determine risk factors for fixation failure in basicervical FNF after internal fixation. METHODS: To identify basicervical FNF with a minimum of 12 months follow-up, we retrospectively reviewed records of 3217 patients who underwent hip fracture surgery from May 2003 to March 2016...

INTRODUCTION: Sliding hip screw fixation is well established in the treatment of trochanteric fractures of the hip. The X-Bolt Dynamic Hip Plating System builds on the successful design features of the sliding hip screw but differs in the nature of the fixation in the femoral head. A randomised pilot study suggested that the X-bolt Dynamic Hip Plating System might provide similar health-related quality of life while reducing the risk of revision surgery when compared with the sliding hip screw...

While many femoral neck fractures can be reliably treated with surgical intervention, Pauwels III femoral neck fractures in the young adult population continue to be a challenging injury, and there is no consensus on optimal treatment. As such, there are past and ongoing biomechanical studies to evaluate the fixation provided by different constructs for this inherently unstable fracture. While many investigations rely on cadavers to evaluate the biomechanical performance of a construct, significant inter-subject variability can confound the analysis...

With the introduction of the World Hip Trauma Evaluation Four clinical trial, fixation of pertrochanteric neck of femur fractures is becoming a hot topic. In this trial, the novel X-Bolt expanding bolt implant is being compared with the current gold standard of a sliding hip screw. We present a previously undescribed complication when inserting the bolt into the femoral head, where the expandable wings penetrate the femoral neck due to misplacement of the bone crusher or the X-Bolt prosthesis. This unforeseen complication required the introduction of several additional corrective intraoperative steps...

AIMS: To compare the outcomes for trochanteric fractures treated with a sliding hip screw (SHS) or a cephalomedullary nail. PATIENTS AND METHODS: A total of 400 patients with a trochanteric hip fracture were randomised to receive a SHS or a cephalomedullary nail (Targon PFT). All surviving patients were followed up to one year from injury. Functional outcome was assessed by a research nurse blinded to the implant used. RESULTS: Recovery of mobility, as assessed by a mobility scale, was superior for those treated with the intramedullary nail compared with the SHS at eight weeks, three and nine months (p-values between 0...

BACKGROUND: In treatment of unstable trochanteric fractures dynamic hip screw and Medoff sliding plate devices are designed to allow secondary fracture impaction, whereas intramedullary nails aim to maintain fracture alignment. Different treatment protocols are used by two similar Swedish regional emergency care hospitals. Dynamic hip screw is used for fractures considered as stable within the respective treatment protocol, whereas one treatment protocol (Medoff sliding plate/dynamic hip screw) uses biaxial Medoff sliding plate for unstable pertrochanteric fractures and uniaxial Medoff sliding plate for subtrochanteric fractures, the second (intramedullary nail/dynamic hip screw) uses intramedullary nail for subtrochanteric fractures and for pertrochanteric fractures with intertrochanteric comminution or subtrochanteric extension...

The study was aimed at the clinical and biomechanical analyses of the sliding hip screw breakage with the use of finite element method. We have identified two patients with the sliding screw breakage. In the first patient, the biomechanical analysis revealed the reduced stress values σHMH not exceeding the yield limit or strength limit of the implant. The yield limit was exceeded in second one. Clinical and biomechanical analyses have demonstrated that adherence to technical requirements of the appropriate osteosynthesis implementation is the principal condition of timely healing since it prevents the material failure...

INTRODUCTION: Trochanteric fractures are frequent and generally associated with bone fragility. There is still debate on the best fixation device to treat stable or rather stable trochanteric fractures: we report our clinical and radiological results of fixation with Proximal Femoral Nail "antirotation" (PFNa) in a population of patients compared to a control group treated by Sliding Hip Screw (SHS). MATERIALS AND METHODS: A prospective study was conducted in 71 consecutive patients treated by PFNa (group A), and 69 by a SHS (group B), with a mean age of 81...

Acetabular fractures potentially account for up to half of all pelvic fractures, while pelvic fractures potentially account for over one-tenth of all human bone fractures. This is the first biomechanical study to assess acetabular fracture fixation using plates versus cables in the presence of a total hip arthroplasty, as done for the elderly. In Phase 1, finite element (FE) models compared a standard plate method versus 3 cable methods for repairing an acetabular fracture (type: anterior column plus posterior hemi-transverse) subjected to a physiological-type compressive load of 2207N representing 3 x body weight for a 75kg person during walking...

PURPOSE: Good results of the cephalomedullary nails have been reported in proximal femoral fractures recently. Based on length of nails and shape of screws fixed in a femoral head for proximal fragment fixation, the proper nail length was in dispute. The purpose of this study was to evaluate the clinical and radiological results of a long cephalomedullary hip nail for the treatment of comminuted subtrochanteric femoral fractures. MATERIALS AND METHODS: Twenty-one consecutive patients with severe subtrochanteric femoral fractures who had undergone intramedullary fixation using long-PFNA II between March 2010 and March 2013 were followed-up for over 12 months...

OBJECTIVES: The optimum treatment with intramedullary nails (IMN) or sliding hip screws (SHS) for type 31-A2 trochanteric fractures remains controversial. Therefore, we performed a meta-analysis of randomized controlled trials (RCTs) to compare IMN with SHS in AO/OTA 31-A2 trochanteric fractures. MATERIAL AND METHODS: Databases including PubMed, Cochrane, and Embase were searched to identify RCTs published before December 2016, which compared IMN with SHS for intraoperative and postoperative outcomes in AO/OTA 31-A2 trochanteric fractures...

OBJECTIVE: Pauwels III femoral neck fractures are highly unstable. These fractures are commonly treated with three cannulated screws or sliding hip screw (SHS) implants, however high rates of non-union persist. A hybrid SHS construct has recently been proposed. The objective of the study was to compare this construct to the familiar inverted triad of cannulated screws and to a single SHS. METHODS: Fourth generation biomechanical femur analogs were used to create a highly repeatable injury model...
