Increased risk of osteoporosis, fractures, and avascular necrosis (AVN) has been suggested in multiple sclerosis (MS). Patients with MS are often exposed to corticosteroid treatment (CST) during the disease course and conflicting reports exist regarding complications of CST. Our study aims to investigate the association between cumulative doses of CST and radiographic evaluation of AVN of the f...

Posttraumatic osteonecrosis of the femoral head (ONFH) is the most serious complication after fracture dislocation of the femoral head. The rate of this complication was reported to range from 1.7% to 40%. Although the development of posttraumatic osteonecrosis normally occurs within 2 years of injury, there are some reports of the late development ONFH. The authors encountered a case of posttr...

Untreated osteonecrosis of the femoral head ultimately leads to collapse and disintegration of hip joint. The predegenerative stages of osteonecrosis especially when seen in young adults, should be treated by a femoral head preservation operation with the objective to delay and possibly to avert the above consequences. Previously head preserving surgeries were not in vogue so total hip replacem...

The Girdlestone procedure is an excision arthroplasty of the hip. Rarely used nowadays, it was required in a young patient following discovery of avascular necrosis of the femoral head as a result of septic emboli from infective endocarditis in an intravenous drug user. This procedure was deemed necessary based on poor cardiac function and anaesthetic risk. During this case report we will discu...

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...

Hip dislocations during sporting activities represent only 2%-5% of all hip dislocations. Most hip dislocations in sports can be categorised as "less complicated traumatic hip dislocations" by the Stewart-Milford classification due to the fact that minimal force is involved. The incidence of avascular necrosis of the femoral head greatly increases if the time to reduction is more than six hours...

Osteochondritis dissecans is a condition affecting a joint in which a variably sized wedge of subchondral bone and its overlying cartilage dies and becomes detached from the articular surface. Although it occurs most often in the knee joint of young male athletes, other reported sites of involvement include the patella, the capitellum, the talar dome, and the femoral head.I In contrast, the occ...

The efficacy of traction before an attempted closed reduction for patients with developmental dislocation of the hip remains controversial. We treated 55 children (62 dislocations of the hip) by preliminary, prolonged traction for a mean of eight weeks. All were followed up for at least two years in order to observe the development of any avascular changes within the femoral head. Of the 55 chi...

Osteonecrosis of femoral head (ONFH) is a challenging disease. Regardless of underlying causes, the ultimate result in all cases is disruption of femoral head blood supply. Once the disease starts, it is progressive in 80% of cases. Since the majority of the affected individuals are young, every effort should be focused on preserving the patients own femoral head. These years, the role of angio...

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...
