We report a case with implant failure after nailing of an unstable pertrochanteric fracture with dynamic hip screw. The patient presented with a medial sided thigh pain at 5 years after the surgery. Plain radiographs showed nonunion of the fracture with distant migration of assembled hip screw and side plate to the subcutaneous area of the inner thigh.

BACKGROUND: Proximal femoral fracture rates are increasing due to osteoporosis and traffic accident. Proximal femoral nails are routinely used in the treatment of these fractures on the proximal femur. AIMS: The present study aimed to compare various combination and to determine ideal proximal lag screw (PLS) position on the pertrochanteric fractures (AO classification 31-A1) of femur by using optimised finite element analysis. STUDY DESIGN: Biomechanical Study...

INTRODUCTION: The aim of this study was to prospectively analyze the role of primary hemiarthroplasty in unstable osteoporotic pertrochanteric fractures (AO/OTA Type 31 A2.3), with emphasis given to postoperative Functional Independent Measure (FIM) and Harris Hip Score (HHS). METHODS: Fifty-six consecutive patients (average age 78.25 ± 5.45), out of which 24 males (79.29 ± 4.99) and 32 females (77.47 ± 5.72), with unstable pertrochanteric femoral fractures, operated with primary hemiarthroplasty procedure from 2012 to 2014 were included in this prospective study with a follow-up of two years...

BACKGROUND: Intramedullary and extramedullary strategies of pertrochanteric fracture fixation are still controversial, but new percutaneous devices may give advantages regarding operative time, blood loss and rate of cardiovascular complications. We retrospectively analyze our cases regarding Anteversa(®) plate (Intrauma, Turin, Italy) fixation of pertrochanteric femoral fractures, focusing on the correlation between two radiographical parameters (tip-apex distance "TAD" and calcar referenced tip-apex distance "CalTAD") and the occurrence of cut-out...

BACKGROUND: In the United States intertrochanteric and pertrochanteric fractures occur at a rate of more than 150,000 cases annually. Current standard of care for these fractures includes fixation with either a cephalomedullary nail (CMN) or a sliding hip screw (SHS). The purpose of this study was to compare failure and medical complications of intertrochanteric femoral fractures repaired by CMN or SHS. METHODS: This study is a retrospective cohort study that included 249 patients with AO/OTA 31 A1...

Hip arthroplasty in young patients requires thoughtful preoperative planning. Patients with proximal femoral bone loss complicate this planning and may require a staged procedure to optimize implant insertion. We report on a case of a 26-year-old woman with secondary hip arthritis from developmental dysplasia of the hip and a large pertrochanteric bone cyst that was treated with staged total hip arthroplasty. The cyst was decompressed and filled with an osteoconductive and osteoinductive bone graft substitute called EquivaBone...

Background and purpose - The proximal femur locking compression plate (PF-LCP) is a new concept in the treatment of hip fractures. When releasing new implants onto the market, biomechanical studies are conducted to evaluate performance of the implant. We investigated the relation between biomechanical and clinical studies on PF-LCP. Methods - A systematic literature search of relevant biomechanical and clinical studies was conducted in PubMed on December 1, 2015. 7 biomechanical studies and 15 clinical studies were included...

Femur fracture is one of the common diseases in the elderly. In this paper, an automatic and efficient classification method of femoral pertrochanteric fractures is proposed based on image segmentation techniques. The types of femoral pertrochanteric fracture are defined firstly according to the difference of fracture parts. To reduce the computational complexity, only four directions images are used in each 3D femur, i.e. the anterior, the anterolateral, the posterior and the posterolateral images of a femur...

OBJECTIVE: To perform a retrospective radiographic assessment of the reduction and implant position in the femoral head in patients with pertrochanteric fractures treated with cephalomedullary nailing in the lateral position versus traction table. METHODS: Radiographs of patients with pertrochanteric fracture of the femur treated with cephalomedullary nailing in the lateral position and traction table were retrospectively evaluated. For the evaluation we used the anteroposterior radiographic view of the pelvis and the lateral view of the affected side...

BACKGROUND: Instability of osteoporotic pertrochanteric fractures is defined by loss of medial/lateral cortical integrity with the posteromedial fragment including the lesser trochanter being pivotal for load distribution. Literature addressing the importance of lesser trochanter refixation is scarce. To clarify the effect of lesser trochanter refixation on primary stability in these fractures, following study was performed. METHODS: 21 femora were match-paired in 3 groups and osteotomized, creating pertrochanteric fractures (AO-31A2)...

We present final results of a study comparing teriparatide 20 μg every day (QD) with risedronate 35 mg once per week (QW) started within 2 weeks after surgery for a pertrochanteric hip fracture. Patients with BMD T-score ≤ -2.0 and 25OHD ≥9.2 ng/mL were randomized to receive 26-week double-dummy treatment plus calcium and vitamin D, followed by 52-week open-label treatment with the same assigned active drug. Primary endpoint was change from baseline in lumbar spine (LS) BMD at 78 weeks. Secondary and exploratory endpoints were change in BMD at the proximal femur, function, hip pain (Charnley score and 100 mm Visual Analog Scale [VAS]), quality of life (Short Form-36), radiology outcomes, and safety...

BACKGROUND: In this study we describe the morphology of the posteromedial fragment in pertrochanteric fractures using 3D CT scans and answer two questions 1) Do differences exist between the 3D CT appearances of posteromedial fragments and the depictions made in the AO classification 2) Does the posteromedial fragment affect stability in pertrochanteric fractures, in terms of fracture collapse? METHODS: Preoperative CT scans of eight 31-A1 and fifty 31-A2 fractures were analysed...

This study compared patients who underwent treatment with short or long cephalomedullary nails with integrated cephalocervical screws and linear compression. Patients with AO/OTA 31-A2 or A3 pertrochanteric fractures treated with either short (n=72) or long (n=97) InterTAN (Smith & Nephew, Memphis, Tennessee) cephalomedullary nails were reviewed. Information on perioperative measures (estimated blood loss, surgical time, and fluoroscopy time) and postoperative orthopedic complications (infection, implant failure, screw cutout, and periprosthetic femur fracture) was included...

BACKGROUND: Osteoporosis drugs might affect fracture-healing. We therefore studied the effects of teriparatide in comparison with risedronate on recovery after pertrochanteric hip fractures. METHODS: The study was a randomized, multicenter, active-controlled, 78-week trial comparing teriparatide (20 μg/day) with risedronate (35 mg/week) initiated within 2 weeks after fixation of a low-trauma pertrochanteric hip fracture (AO/OTA 31-A1 or 31-A2). The main inclusion criteria were a bone mineral density T-score of ≤-2...

We investigated whether a proximal femoral nail can be implanted without a distal locking screw in AO/OTA 31-A1 and 31-A2 pertrochanteric stable femur fractures. A multicentre, randomised study was conducted in six level-two trauma centres in our area (Puglia, Italy). A total of 333 patients received their allocated intervention (162 in the locking group [LG] and 171 in the unlocking group [UG]) and 266 patients were included in the final analysis at 1year. Our data showed no statistically significant difference between the two groups at 1-year follow-up for ability to walk, SF-36 questionnaire results, residual pain (visual analogue scale [VAS] score) and level of overall satisfaction...

OBJECTIVE: To evaluate the effectiveness of Othofix pertrochanteric fixator for fixation of intertrochanteric fracture. METHODS: A retrospective analysis was made on the clinical data from 36 cases of intertrochanteric fracture treated with Othofix pertrochanteric fixator (OPF group) and 47 cases treated with Gamma nail (Gamma group) between October 2012 and March 2015. There was no significant difference in gender, age, cause of injury, side, AO fracture classification, combined medical disease, and injury to operation time between 2 groups (P > 0...
