thy, characterized by severe joint destruction occurring within a few months, is ascribed to subchondral insufficiency fracture resulting from osteoporosis1 and ischemic hip disease.2 Corticosteroids can cause avascular osteonecrosis of the femoral head, osteoporosis, or both. Most cases of corticosteroid-induced osteonecrosis are caused by exogenous corticosteroid administered for the treatmen...

BACKGROUND Hip resurfacing is a conservative type of total hip arthroplasty but its use is controversial, especially in patients with osteonecrosis. The aim of this study was analysis of the clinical and radiographic outcomes of hip resurfacing in patients with osteonecrosis. MATERIAL/METHODS Between 2007 and 2008, 30 hip resurfacing arthroplasties were performed due to osteoarthritis seconda...

INTRODUCTION Total hip replacement is generally proposed for renal transplant patients with avascular osteonecrosis of the femoral head. PURPOSE The purpose of the study is to report the long-term outcome after rehabilitation of bilateral total hip arthroplasty in a patient with renal transplantation suffering from avascular osteonecrosis of the both femoral heads. MATERIAL AND METHOD The p...

Osteonecrosis, also referred to as avascular necrosis, refers to the death of cells within bone caused by a lack of circulation. It has been documented in bones throughout the body. In the foot, osteonecrosis is most commonly seen in the talus, the first and second metatarsals, and the navicular. Although uncommon, osteonecrosis has been documented in almost every bone of the foot and therefore...

Osteonecrosis is a common disorder that may go clinically unrecognized or may result in the collapse of the architecture of bone, determining severe anatomic alterations of the involved site. Osteonecrosis is not a specific disease entity, but rather the result of a number of conditions ultimately leading to an impairment of blood supply to the bone tissue, although there is evidence that modif...

Background: Osteonecrosis is common after taking Temgesic and Norgesic. This study intended to suggest the preferable surgical treatment in osteonecrosis patients who use these drugs. Methods: Twenty tree patients with hip osteonecrosis who were hospitalized in the Kerman hospitals after using Temgesic and Norgesic were followed for about 14 months from 2008 to 2010 (from a minimum of 2 months ...

Our aim is to analyse the clinical outcome of a series of patients affected by avascular necrosis of the femoral head and treated with core-decompression technique and autologous stromal cells of the bone marrow.We enrolled in our study 29 patients with 31 hips in total affected by avascular necrosis of the femoral head. The clinical and radiological outcome has been assessed through self-admin...

INTRODUCTION Avascular necrosis (AVN) of the bones of the wrist most commonly involves the lunate followed by the proximal pole of the scaphoid and the capitate. Trapezium avascular necrosis is extremely rare with only two cases reported in the literature, both of which were treated surgically. In this article, we report a unique case of trapezium avascular necrosis treated conservatively. CA...
