The patient was a 51-year-old man who was evaluated by a physical therapist for a chief complaint of right hip pain. The patient was treated with a single bout of nonthrust hip joint mobilizations, but due to the patient's atypical response and long-term use of oral corticosteroid medications, he was referred to his primary care physician. Radiographs and subsequent magnetic resonance imaging r...

OBJECTIVE To evaluate the biomechanical changes of balloon inflating and cement filling in avascular necrosis of the femoral head using finite-element analysis. METHODS The procedure of percutaneous balloon inflating and cement filling was simulated in fresh specimen of human femoral head. CT scan and three-dimensional reconstruction were used to establish the three-dimensional model of the f...

The Pavlik harness was used in the treatment of complete congenital dislocation of one or both hips in a series of infants, on either an outpatient or an inpatient basis. The results in the two groups were compared. For the children treated as outpatients the incidence of avascular necrosis of the femoral head was 7.2 per cent and for the group treated as inpatients the rate was 28 per cent. Ap...

Background: Femoral head avascular necrosis is the cause of paralyzing status of youth population. Initial diagnosisis the main element in treating the disease. Bone grafting and core decompression are the approved cures at the earlysteps of the disease. Hip replacement in a total manner is the common cure in the final stages. The optimal treatment inthe intermediate stages is...

Since the recent publication of studies of the vascular pattern of the proximal femoral epiphysis in man by Tucker (1949), Trueta and Harrison (1953), Judet, Judet, Lagrange and Dunoyer (1955), and Trueta (1957) there has been a renewed interest in the mechanism of capital necrosis after fractures of the femoral neck. The literature on the subject is so extensive that no effort will be made her...

We reviewed 41 hips in 40 patients at three to 11 years (average 6.3 years) after Sugioka transtrochanteric rotational osteotomy for non-traumatic avascular necrosis of the femoral head. The clinical results were excellent or good in 23 hips (56%) and the radiological success rate was 56%. Failure was due to fracture of the femoral neck, nonunion of the osteotomy, secondary collapse, or osteoar...

This case deals with the avascular necrosis or osteonecrosis of the femoral head in a 41-year-old male presenting to a chiropractor's office. In addition to the clinical picture, diagnostic imaging should be performed to confirm the presence and extent of hip avascular necrosis. Referral to an orthopedic specialist is key and treatment is mainly surgical.
