This study was conducted to identify the risk of avascular necrosis of the femoral head after arthroscopic femoroplasty extending to the posterolateral femoral neck, the source of the primary blood supply to the femoral head. Cam lesions of femoroacetabular impingement are typically anterior along the junction of the femoral head and neck. However, anatomic variations can involve the posterolat...

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...

Introduction: Avascular necrosis (AVN) of the femoral head is a leading cause of end-stage joint disease in the young population that can conduct patients to total hip replacement in early life. There are various risk factors including, trauma, corticosteroids, thrombosis, hypertension, and alcohol. There is a growing number of femoral head AVN patients with a history of self-medication with he...

brucellosis is a zoonotic disease mostly transmitted to humans through consumption of unpasteurized dairy products and can lead to a systemic disease with any organ involvement. in this report, we describe a case of brucellosis-induced avascular necrosis of the hip. brucellosis was diagnosed through serological tests, and avascular necrosis of the femoral head was confirmed by pelvic mri. the p...

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...

INTRODUCTION The avascular necrosis of the femoral head represents the death of bone tissue due to the lack of blood supply. The disease has a progressive evolution and left untreated leads to femoral head collapse and severe arthritis. CASE PRESENTATION We present a case of a pertrochanteric fracture which has been successfully operated with a dynamic interlocking trochanteric gamma nail on ...

INTRODUCTION: Avascular necrosis of the femoral head (FHN) is a common complication with disabling effect for young patients after high dose corticosteroid treatment [1]. Recently, we could show that steroids have a vasoconstrictive effect on lateral epiphyseal arteries of the femoral head (FH) which could lead to FH ischemia and subsequent necrosis [2]. In the current study we investigated the...
