BACKGROUND The high loads on adolescent athletes' musculoskeletal system are known to cause morphological and degenerative changes in bone, intervertebral discs and joints. It has been suggested that the cam deformity of the proximal femoral head originates from a subclinical slipped capital femoral epiphysis (SCFE) as a result of non-physiological loading. The perichondrial fibrocartilaginous ...

Femoral fractures have to be considered frequent causes of hospital admission for the elderly. These fractures are characterized by an uncertain prognosis in terms of both morbidity and mortality. The management of proximal femoral fractures in the elderly should be multidisciplinary, indeed the fall causing the fracture might follow a neurological, metabolic or cardiovascular disorder. Thus th...

PURPOSE We aimed to quantify proximal femoral shortening after operation with compression hip screws for intertrochanteric fracture in patients under the age of 60 years. MATERIALS AND METHODS We followed 37 consecutive patients with intertrochanteric fractures treated with compression hip screws from March 2005 to February 2014. We designated the aspect of the fracture, a defect of the poste...

Our aim was to assess the local extent of osteocyte death in the proximal femur of 16 patients with osteonecrosis of the femoral head. We performed histological examination of the femoral heads and cancellous bone biopsies from four regions of the proximal femur in patients undergoing total hip arthroplasty. A control group consisted of 19 patients with osteoarthritis. All histological specimen...

It is unclear whether there is a limit to the amount of distal bone required to support fixation of supracondylar periprosthetic femoral fractures. This retrospective multicentre study evaluated lateral locked plating of periprosthetic supracondylar femoral fractures and compared the results according to extension of the fracture distal with the proximal border of the femoral prosthetic compone...

BACKGROUND The purpose of this study was to assess the clinical outcome and complications of megaprostheses for massive proximal femoral bone loss after failed total hip arthroplasty. METHODS Between June 1997 and December 2002, 12 patients (12 hips) with massive proximal femoral deficiencies had reconstruction of the hip using proximal femoral megaprostheses. The average age of the patients ...

Is the proximal bone resorption around the femoral stem after hip arthroplasty really caused by reduced stress?

Osteonecrotic collapse of the femoral head is a common refractory disease in orthopedics, and the occurrence of collapse is an important factor in the prognosis of this condition. Osteonecrotic collapse of the femoral head can be delayed or prevented by the formation of a sclerotic rim. This study used finite element analysis to evaluate the mechanical role of a proximal sclerotic rim on stress...
