Spontaneous osteonecrosis of the knee is a unilateral and unifocal disorder commonly affecting the medial femoral condylar epiphysis. The medial tibial plateau, patella or the lateral femoral condyle can also be affected with a lower incidence [ 1 ] . Reddy and Frederick reported that the medial femoral condylar predominance can be explained by poor arterial supply of the medial femoral condyle...

Although much has been published on the causes of slipped upper femoral epiphysis and the results of treatment, little attention has been given to the mechanism of the slip. This study presents the results of the analysis of 13 adolescent femora, and the attempts to reproduce the radiological appearances of a typical slip. The mean age of the skeletons was 13 years (11 to 15). It was found that...

INTRODUCTION: Slipped capital femoral epiphysis (SCFE) is the most common hip disorder of adolescent children [1]. It results in fracture of the growth cartilage, separating the proximal femoral epiphysis from the metaphysis, due to hormonal and mechanical factors [2]. The most widely accepted treatment for stable SCFE (defined by the ability to bear weight on the affected limb) has been a sing...

Early closure of the growth plate after fixing a slipped upper femoral epiphysis is often regarded as favourable since, if growth of the femoral neck continues, the metal may lose its grip on the epiphysis with the possibility of further slipping. However, in the young child early fusion may result in leg length discrepancy and limited motion. The hook-pin (Hansson 1982) permits continued growt...

The cartilaginous epiphysis of the distal femur is vascularized by a network of cartilage canals during prenatal development. The vascular invasion of the epiphysis begins at approximately eight to ten weeks of gestation with the initiation of cartilage canal formation. A complex vascular system develops within the canals and is well defined by fourteen weeks of gestation. The vascular system i...

Avascular necrosis is a serious complication of slipped capital femoral epiphysis and is difficult to treat. The reported incidence varies from 3% to 47% of patients. The aims of treatment are to maintain the range of movement of the hip and to prevent collapse of the femoral head. At present there are no clear guidelines for the management of this condition and treatment can be difficult and u...

UNLABELLED To assess the importance of using conventional magnetic resonance imaging and T2 mapping to determine the pre-slip stage of the contralateral epiphysis in patients with a clinical and radiographic diagnosis of unilateral proximal femoral epiphysiolysis who were initially treated with in-situ fixation. METHODS This prospective clinical study on 11 patients with unilateral epiphysiol...
