The use of alternative bearing surfaces for total hip arthroplasty has become popular to minimize wear and increase longevity, especially in young patients. Oxidized zirconium (Oxinium; Smith & Nephew, Memphis, Tennessee) femoral heads were introduced in the past decade for use in total hip arthroplasty. The advantages of oxidized zirconium include less risk of fracture compared with traditiona...

Sixty two patients with displaced femoral neck fractures treated by percutaneous pinning are reviewed. There were 37 females and 25 males with an average age of 63.7 years. There were 36 Garden grade III and 26 grade IV fractures. Twenty three patients had other medical conditions. Fourteen patients were operated under local anaesthesia. Superficial wound infection was found in three cases with...

Avascular necrosis (AVN) of femoral head is a recognised complication of fracture dislocation of the hip joint but is not studied frequently in relation to acetabulum fractures. The aim was to establish the relationship between obturator externus and piriformis muscle morphology in acetabulum fractures and potenital development of AVN of the femoral head. Twenty-five fractures were included in ...

Case Description- Twenty four cases of dogs and cats were presented for inability to move and/or getting up one of the legs while walking and leaning on the other.Clinical Findings-Physical and radiographic examinations revealed that the patients had coxofemoral luxation, hip dysplasia, comminuted acetabular fracture, avascular necrosis of femoral head and/or femur head fracture.Tre...

Aseptic osteonecrosis is a frequent pathology. It corresponds to epiphyseal bone necrosis, secondary ischemic and/or cytotoxic mechanisms. not specific disease, but rather the final outcome of various pathological situations in which there disturbance intraosseous circulation femoral head. This explains usual names avascular necrosis or aseptic necrosis. may be unilateral, bilateral multifocal....

We describe a method of intertrochanteric osteotomy with posterior rotation of the femoral head and neck. We analysed 45 hips in 44 children and adolescents aged from six to 18 years with residual dysplasia after conservative (35) and operative (10) treatment of developmental dysplasia of the hip complicated by avascular necrosis of the femoral head. In ten, femoral osteotomy was combined with ...

Osteochondral lesions of the femoral head are uncommon and few studies have reported their imaging findings. Since joints are at risk of early degeneration after osteochondral damage, timely recognition is important. Osteochondral lesions of femoral head may often be necessary to differentiate from avascular necrosis. Here, we report a case of osteochondral lesions on bilateral femoral heads. T...

Mechanical factors have now been excluded as the main cause of non-union in fractures of the femoral neck : the development of efficient methods of internal fixation has removed this source of non-union and the chief remaining cause is disturbance of the circulation of blood to the capital fragment. The incidence of avascular necrosis of the femoral head appears to depend upon normal variations...

BACKGROUND 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...
