INTRODUCTION Osteonecrosis of the femoral head is a progressive disease that leads to femoral head collapse and osteoarthritis. Our goal in treating osteonecrosis is to preserve, not to replace, the femoral head. CASE PRESENTATION We present the case of a patient with bilateral osteonecrosis of the femoral head treated with autologous cultured osteoblast injection. CONCLUSION Although our e...

Osteonecrosis of the femoral head is an idiopathic, debilitating and progressive disease. A number of traumatic or non-traumatic animal models have been reported for research on osteonecrosis. This study was performed to compare the efficacy of femoral head osteonecrosis in rabbits by traumatic and non-traumatic methods. Twenty-seven New Zealand White rabbits were divided into three experimenta...

BACKGROUND To investigate the efficacy of the sole core decompression surgery for the treatment of steroid-induced femoral head osteonecrosis. METHODS The model was established by administration of steroids in combination with horse serum. The rabbits with bilateral femoral head osteonecrosis were randomly selected to do the one side of core decompression. The other side was used as the sham....

Legg-Calvé-Perthes disease (LCPD) is an idiopathic osteonecrosis of the femoral head with variable complications and resultant deformity of the femoral head and osteoarthritis. Suggested risk factors are acetabular retroversion, obesity, latitude, hyperactivity, and coagulopathy. The most commonly applied classification is based on radiolucency in the lateral pillar of the femoral head, which i...

BACKGROUND We previously reported that ethanol-containing liquid diet feeding induces osteonecrosis of the femoral head in male rats. Also, it was reported that a large amount of consumed ethanol and a long-term history of drinking were risk factors for osteonecrosis of the femoral head, and that the frequency of alcohol-induced osteonecrosis of the femoral head in males was much greater than i...

Introduction: Avascular necrosis (AVN) of the femoral head is a leading cause of end-stage joint disease in the young population that can conduct patients to total hip replacement in early life. There are various risk factors including, trauma, corticosteroids, thrombosis, hypertension, and alcohol. There is a growing number of femoral head AVN patients with a history of self-medication with he...

BACKGROUND Osteonecrosis of the femoral head is classified into idiopathic and secondary forms. A number of etiological factors in the development of osteonecrosis have been suggested but the biological mechanisms are still unclear. Recently, some reports suggested that the apoptosis is closely related to osteonecrosis of the femoral head. Therefore, this study examined the expression of apopto...

Osteonecrosis of the femoral head is an intractable disease often occurring in patients aged 30-40 years that can cause femoral head collapse, pain, and gait disturbance. Background factors, including corticosteroid use, alcohol intake, and idiopathic causes, have been indicated. It is estimated that 70-80 % of osteonecrosis patients experience femoral head collapse, for which total hip arthrop...

We report a case of osteonecrosis of the femoral head in a young man who is a carrier of the prothrombin gene mutation. We suggest that an electrical injury to his lower limb may have triggered intravascular thrombosis as a result of this mutation with subsequent osteonecrosis of the femoral head. No case of osteonecrosis of the femoral head secondary to a distant electrical injury has previous...
