Avascular necrosis of the femoral head (ANFH) is a pathologic process that results from interruption of blood supply to the femur bone resulting in the death of bone cells and collapse of the femoral head. Nontraumatic ANFH continuesto be a significant challenge to orthopedic surgeons. While the exact mechanisms remain elusive, many new insights have emerged from research in the last decade tha...

Chemically induced avascular necrosis of bone is a well documented entity. Indomethacin is one of the causes of this condition but is often difficult to recognise. Review of the literature shows that only one case of indomethacin induced avascular necrosis has been reported in the English language between 1966 and the present. The case of a young healthy man, who developed avascular necrosis of...

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...

We used technetium-99m antimony colloid to visualize the bone marrow of the head of the femur within twenty-four hours after interruption of the blood supply by subcapital osteotomy and section of the ligamentum teres in thirteen rabbits and within twenty-four hours after a subcapital fracture in thirty patients. Of the rabbits, all showed loss of marrow radioactivity over the affected femoral ...

The earliest attempt at classifying avascular necrosis of the femoral head was proposed by Ficat and Arlet in 1964 [2], before the advent of MRI. The purpose of the classification was to provide prognostic insight and compare treatment options. Ficat modified the classification to include invasive testing procedures and a preclinical, preradiographic stage in 1985 [1]. Since then the system has...

The association of transcervical fractures of the femur with avascular necrosis of the capital fragment was recognised many years ago. Nevertheless several basic questions, such as the incidence ofavascular necrosis, the extent and pattern ofbone death and revascularisation and also the role played by avascular necrosis in non-union of these fractures, remain unanswered. In the hope that a hist...

Chondrosarcomas are the second most common bone sarcomas, accounting for less than 0.5% of all cancers. The treatment plan can be improved by analyzing clinical characteristics and patterns. rarity slow-growing nature this tumour often lead to prolonged symptoms also initial misdiagnosis with avascular necrosis femur, benign lesions like chondroblastoma. reports patient suggested femur head.
