Osteonecrosis of the femoral head is a progressive disease. Without operative intervention, it most often results in collapse and deterioration of the joint. Many joint-preserving surgeries have been implemented, but no uniform treatment exists. The authors report a modified technique of tantalum rod implantation combined with vascularized iliac grafting for the treatment of osteonecrosis of th...

BACKGROUND Transtrochanteric rotational osteotomy (TRO) is a controversial hip-preserving procedure with a variable success rate. The healing process of femoral head osteonecrosis after TRO has been poorly explained till now. This study aimed to evaluate the healing process of previously transposed necrotic lesion after a TRO for nontraumatic osteonecrosis of the femoral head using computed tom...

The purpose of this study was to determine the prevalence of adverse reactions to metal debris (ARMD) following large-diameter metal-on-metal total hip arthroplasty. The authors examined the potential for using magnetic resonance imaging to screen for pseudotumors in 108 hips 2 years postoperatively. Serum cobalt and chromium concentrations were measured in 80 hips that underwent unilateral tot...

PURPOSE. To measure the transverse acetabular ligament (TAL) anteversion in hips with severe deformity, using fluoroscopy-computed tomographic navigation. METHODS. 31 hips in 10 men and 19 women aged 40 to 78 (mean, 58.7) years who underwent total hip arthroplasty for primary osteoarthritis (n=6) or osteoarthritis secondary to developmental hip dysplasia (n=19) or congenital hip dislocation (n=...

The clinical challenge in paediatric hip pain is to distinguish urgent conditions such as infection of the hip joint from the more common irritable hip. Transient synovitis is one of the most common causes in children over 3 years of age but it has similar early symptoms to septic arthritis. This article offers a guide to assessment, an overview of common causes, and clarity around which childr...

OBJECTIVE The purpose of this article is to relate intramedullary perfusion of the proximal femur to severity of osteonecrosis of the femoral head by using dynamic contrast-enhanced MRI (DCE-MRI). SUBJECTS AND METHODS Twelve patients (14 symptomatic hips) who underwent DCE-MRI and had subsequent core decompression of the femoral head were examined. Hips were graded for severity according to M...

Free vascularized fibular grafting (FVFG) has been reported to be an effective method of treating osteonecrosis of the femoral head (ONFH). This study evaluated whether postoperative maintenance doses of corticosteroids had an adverse effect on FVFG outcomes in patients with corticosteroid-induced ONFH. We retrospectively reviewed the records of 39 patients (67 hips) who had received maintenanc...
