OBJECTIVE Non-traumatic osteonecrosis of the femoral head (ONF) is considered to be a disease that occurs primarily due to ischemia of the femoral head, while its etiology and pathology are not fully understood. It is therefore necessary to identify the characteristics of the hemodynamics of the femoral head. In this study, the hemodynamics in the ilium and proximal regions of the femur, includ...

Avascular necrosis of the femoral head is usually seen in children aged 1.5 to 10 years, reaching a peak incidence between the ages of 4 and 9. Avascular necrosis of the femoral head is a known complication of corticosteroid therapy in acute lymphoblastic leukemia. There are few reports in the literature regarding the natural history of this condition, and there is no consensus on its managemen...

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 ...

Purpose. To compare the costs of femoral head banking versus bone substitutes. Methods. Records of femoral head banking from 1998 to 2008 were reviewed. The cost of allogenic cancellous bone graft was calculated by estimating the direct expenditure of femoral head procurement, screening tests, and storage, and then divided by the amount of bone harvested. Results. 326 females and 141 males (mea...

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...

Femoral head necrosis is a rare but devastating complication following femoral neck fracture. The reported incidence of avascular necrosis after femoral neck fracture fixation varies widely, and there is no consensus regarding its risk factors. The aim of this study was to analyze the risk factors for femoral head necrosis after internal fixation in femoral neck fracture. This retrospective stu...

INTRODUCTION Obturator hip dislocations with an associated osteochondral fracture of the femoral head are uncommon. The treatment of these injuries is challenging and the functional outcomes are poor. Though the injury pattern has been described previously in literature, there are few published reports regarding treatment options. This case report illustrates a novel technique for fixation and ...

INTRODUCTION Few data are available concerning structural changes at the hip observed by magnetic resonance imaging (MRI) in people with or without hip osteoarthritis (OA). The aim of this study was to compare cartilage volume and the presence of cartilage defects and bone marrow lesions (BMLs) in participants with and without diagnosed hip OA. METHODS Femoral head cartilage volume was measur...
