BACKGROUND Avascular necrosis of the femoral head causes significant morbidity and occurs in up to 20,000 people per year. A variety of nonoperative and operative measures have been trialled however a definitive treatment algorithm is yet to be established. Young adults in many cases have undergone multiple surgical procedures in their lifetime with increasing risks of complications. Less invas...

Fifty-six patients with ununited intracapsular fractures of the femoral neck were treated by internal fixation and muscle-pedicle bone grafting. All had some absorption of the femoral neck, and many had avascular necrosis of the femoral head. At operation the sclerosed surfaces of the fractures were freshened, the avascular femoral head was decompressed and the muscle-pedicle graft was fixed wi...

This report describes the pathological characterizations of a rare case of necrosis of the femoral head that was spontaneous, bilateral, avascular and nontraumatic. A 14-month-old beagle dog was presented with pain in the hind limbs. At necropsy, the articular surface in the bilateral femoral head was markedly irregular. There were no gross abnormalities other than in the hip joints. Microscopi...

The clinical and pathological findings in a case of early avascular necrosis of the femoral head following renal transplantation are described. Regions of subchondral bone distant from the principal lesions showed increased numbers of empty osteocytic lacunae. This has been quantified and it is suggested that a loss of osteocytes is perhaps one of the earliest lesions leading to established ava...

Insufficient blood flow to the proximal femur causes osteonecrosis of femoral head, which is known as head avascular necrosis (AVN). The underlying pathogenesis unclear, risk factors are likely influence microcirculation somewhat, but this has not been confirmed by research. In more than 75% cases, affects head. Methods: From August 2019 March 2022, 4 patients with FBAN were analyzed retrospect...

Two patients with stage IIIB Hodgkin's disease are reported, in whom treatment with cytotoxic and corticosteroid therapy was followed by avascular necrosis of the femoral head.
