Currently, there is no objective indicator for surgical procedures in elderly patients with femoral neck fractures. The purpose of this study was to determine the severity of damage to the retinacula of Weitbrecht based on the type of femoral neck fracture, anatomical and clinical observations. Data from 44 patients treated with artificial femoral head replacement were analyzed for the associat...

OBJECTIVES Because of the contradictory body of evidence related to the potential benefits of helical blades in trochanteric fracture fixation, we studied the effect of bone compaction resulting from the insertion of a proximal femoral nail anti-rotation (PFNA). METHODS We developed a subject-specific computational model of a trochanteric fracture (31-A2 in the AO classification) with lack of...

PURPOSE To determine the outcome of treatment for minimally displaced femoral neck fractures using multiple threaded pins versus sliding compression screws for internal fixation. METHODS The medical records of 62 consecutive elderly patients with minimally displaced intra-capsular femoral neck fractures who underwent internal fixation of the fracture (37 with multiple threaded pins, and 25 wi...

INTRODUCTION Treatment of femoral neck fractures in young adults may require total hip arthroplasty or hip hemiarthroplasty using a bipolar cup. The latter can, however, result in migration of the femoral head and poor long-term results. CASE PRESENTATION We report a case of femoral head migration after hemiarthroplasty performed for femoral neck fracture that had occurred 22 years earlier, w...

treated for carcinoma of the anal canal with a combination of chemotherapy, radiotherapy and surgery. Three years later he presented with a 5-month history of severe left hip pain and a 2-month history of severe right hip pain. He required the assistance of a cane for walking. Clinical concerns included fracture and metastatic disease. A plain film of the pelvis showed diffuse osteopenia. A tec...

background: some studies have previously shown that geometry of proximal femur can affect the probability of fracture and type of fracture. it happens since the geometry of the proximal femur determines how a force is applied to its different parts. in this study, we have compared proximal femur’s geometric characteristics in femoral neck (fnf), intertrochanteric (itf) and subtrochanteric (stf)...

Femoral neck fractures in young patients are usually caused by a high-energy trauma, which results in a perpendicular fracture. Although efforts are focused on preserving the femoral head in young patients, vertical femoral neck fracture is a problematic orthopedic injury due to the domination of shear forces. Due to controversy regarding which fixation method is the best choice, the purpose of...

Few reports in the literature describe the treatment experience of benign lesions of the femoral head and neck. Between July 2005 and August 2009, twenty-four patients with bone tumor of the femoral neck and head were treated at the authors' institution. Fourteen patients had pathological fractures of the femoral neck; in the other 10 patients, the bone cortex was involved. Average tumor size w...

OBJECTIVE To compare the fixation stability in the femoral head with sliding hip screw versus helical blade designs for unstable, intertrochanteric hip fractures. METHODS A simulated, unstable intertrochanteric hip fracture was created in six pairs of cadaveric femurs. One of each pair was treated using an intramedullary nail with a sliding hip screw (ITST) for femoral head fixation and the o...

BACKGROUND AND PURPOSE The micro-architecture of bone has been increasingly recognized as an important determinant of bone strength. Successful operative stabilization of fractures depends on bone strength. We evaluated the osseous micro-architecture and strength of the osteoporotic human femoral head. MATERIAL AND METHODS 6 femoral heads, obtained during arthroplasty surgery for femoral neck...
