Untreated osteonecrosis of the femoral head ultimately leads to collapse and disintegration of hip joint. The predegenerative stages of osteonecrosis especially when seen in young adults, should be treated by a femoral head preservation operation with the objective to delay and possibly to avert the above consequences. Previously head preserving surgeries were not in vogue so total hip replacem...

INTRODUCTOIN: Legg-Calve-Perthes disease (LCPD) is a common juvenile form of ischemic osteonecrosis of the femoral head that affects children between the ages of 2 to 14 years and has the attack rate of 1 in 740 boys and 1 in 3700 girls. LCPD is due to blood supply disruption to the femoral head. Ischemic osteonecrosis of the femoral head remains one of the most challenging conditions to treat ...

The femoral head receives the majority of its blood supply via branches of the medial femoral circumflex artery, whose course runs across the piriformis fossa and along the superior aspect of the femoral neck. Cadaveric studies have demonstrated damage to the medial femoral circumflex artery in cases where the piriformis fossa was the entry point for intramedullary nailing. Although well recogn...

Osteonecrosis in isolated fractures of the acetabulum without dislocation of hip seems to be a known complication, but to our knowledge it has not been reported adequately. The causative nature of post-traumatic femoral head osteonecrosis has not been studied critically. The pathophysiology of osteonecrosis in this case also eludes us. Striking evidence points towards the intra-operative blood ...

The aim of the study was to introduce a new method for measuring the residual displacement of the femoral head after internal fixation and explore the relationship between residual displacement and osteonecrosis with femoral head, and to evaluate the risk factors associated with osteonecrosis of the femoral head in patients with femoral neck fractures treated by closed reduction and percutaneou...

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...

INTRODUCTION Corticosteroid therapy is a well known etiological factor for the development of osteoporosis (“secondary” osteoporosis) and femoral head osteonecrosis. Recently, HMG-CoA reductase inhibitors (popularly known as statins) have been suggested as a treatment option to prevent the development of corticosteroid induced femoral head osteonecrosis [1-2]. The exact mechanism by which stati...

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 Osteonecrosis of the femoral head is a disease which may cause rapid femoral head collapse in relatively young patients. Clinical results of prosthesis replacement in osteonecrosis patients are generally poorer than in age-matched patients with other diagnoses. The ultimate goal in treating these patients is therefore to preserve not replace the involved femoral head. The purposes of...

A relationship between the development of osteonecrosis of the femoral head and systemic corticosteroids has been well established in the literature, particularly in adults. However, the link between osteonecrosis and inhaled corticosteroids is less researched and understood. We report an usual case report of a 10-year-old male who developed ipsilateral femoral head osteonecrosis after long-ter...
