Background: Femoral head osteonecrosis is a progressive disease with disabling outcomes in hip joint if not treated.This study was designed to compare the effects of zoledronic acid plus vitamin E versus zoledronic acid alone insurgical induced femoral head osteonecrosis in rabbits.Methods: 26 Japanese white adult normal male rabbits at 28-32 weeks old were undertaken surgical femoraldislocatio...

Management of pain from skeletal metastases is notoriously difficult. Case reports and case series have described radiofrequency ablation of the obturator nerve branches to the femoral head for treatment of intractable hip pain. Ablation of the obturator branches to the femoral head is technically difficult because of bony and vascular anatomy, including close proximity of the femoral vessels. ...

Femoral osteotomy is performed for osteonecrosis of the femoral head to prevent progression collapse and promote repair process by transposing necrotic lesion nonweight-bearing portion. The purpose this review article was summarize current knowledge on two types osteotomy: transtrochanteric anterior or posterior rotational curved varus osteotomy, both which are currently osteonecrosis, mainly i...

We acknowledge Dr. Andrea Emilio Salvi for his general comments and opinions on hip resurfacing surgical technique and factors that may affect clinical outcome. Even if no specific question or comment is directly related to our study [2], we will try to provide a scientific input on the points raised. The first ‘‘procedural trap’’ reported by Dr. Salvi is in relation to the femoral component st...

INTRODUCTION Femoral neck axis plotting is of great significance in measuring parameters that define femoral head-neck junction sphericity in the group of patients with the femoroacetabular impingement. Literature methods of femoral neck axis determination have weaknesses associated with the risk of obtaining inaccurate values of certain parameters. OBJECTIVE Method of plotting of the femoral...

UNLABELLED Femoral head-neck junction osteochondroplasty is commonly used to treat femoroacetabular impingement, yet remodeling of the osteochondroplasty site is not well described. We therefore describe bony remodeling at the osteochondroplasty site and analyze clinical outcomes and complications associated with femoral osteochondroplasty. We retrospectively reviewed 135 patients (150 hips) wh...

Thirty-four patients were studied throughout the evolution of Perthes' disease. The acetabular changes included osteopoenia of the roof, irregularity of its contour, and decrease in its depth. These changes were proportional to the femoral head involvement. The purpose of the study was to assess the effect of the morphological changes of the femoral head on the acetabulum and the outcome, and t...

Introduction: An impeded blood flow through the femoral head is incriminated in the etiopathogensis of osteonecrosis of the femoral head. Treatment of osteonecrosis of the femoral head still presents a clinical challenge. Recent clinical study demonstrated that transplantation of bone-marrow cells, as a source of mesenchymal stem/progenitor cell fraction, could be a promising new approach for o...

BACKGROUND This study compares the wear characteristics in slipped capital femoral epiphysis (SCFE) with those of primary osteoarthritis (OA) in adult patients with advanced arthritis. METHODS One hundred femoral heads and proximal neck specimens were studied from SCFE patients (16 hips) and from primary OA (84 hips) patients undergoing total hip arthroplasties (THA). Grade 4 chondromalacia w...
