Introduction: Superior femoral epiphysiolysis (SFE) is a most progressive but sometimes abrupt displacement of the head relative to superior metaphysis through cervicocerebral growth plate femur. The often downward and backward. It typical pathology pubescent adolescent, overweight. occurs on average at age 12 years in girls 14 boys. Unstable forms with large displacements have high risk necros...

OBJECTIVE This work aims to perform a biomechanical test to evaluate the effect of interior supporting system and tantalum rod in simulating the treatment of ischemic necrosis of the femoral head. METHOD Three models were established: control group (group A), interior supporting system group (group B), and tantalum rod group (group C). Step-by-step loading was applied on the top of the femora...

We have reviewed 54 hips in 46 patients from 2 to 14 years after a joint-preserving operation for idiopathic avascular necrosis of the femoral head. The choice between core decompression (17 hips), bone grafting (18), rotation osteotomy (15) or varus osteotomy (4) was determined by the stage and location of the area of necrosis. The overall success rate was unexpectedly low at 60%. Core decompr...

Fracture of the femoral head (OTA 31-C1.3) following anterior obturator dislocations are a challenging problem as the fractures are often communited, impacted and with loose osteochondral fragments, making surgical fixation difficult. This can result in residual articular defects if the fragments cannot be internally fixed and need be excised, predisposing to secondary osteoarthritis. Treatment...

Developmental dysplasia of the hip (DDH) causes anatomical changes that cause early coxarthrosis. Although risf factors have been determined, the aetiology and physiopathology remains exactly unknown. Neonatal screening with physical examination and ultrasound have been stablished in order to diagnose this disease early in life. A diagnosis in the first months of life is essential as it enables...

Avascular necrosis of femoral head is not an uncommon chronic disorder of hip in adults. The patient presents to the health facility with varied range of symptoms based on the degree of collapse of the head and arthritic changes at hip. Avascular necrosis of hip presenting as subacute condition with pathological sub capital neck of femur fracture has not yet been reported. The commonly used Fic...

Objective To analyze the effects of the acetabular fracture index (AFI) and other factors on the functional outcome of patients with acetabular fractures involving the posterior wall. Methods Forty-eight patients who underwent surgery in our department were reviewed. According to the AFI, which indicates the percentage of remaining intact posterior acetabular arc, the patients were divided into...

A broken guide wire while operating on hip is one of every surgeon's most dreaded nightmares. We report here a method which was used successfully to retrieve a broken guide wire from a patient who was being operated for core decompression and fibular grafting for avascular necrosis of the femoral head.

We performed 96 Birmingham resurfacing arthroplasties of the hip in 71 consecutive patients with avascular necrosis of the femoral head. A modified neck-capsule-preserving approach was used which is described in detail. The University of California, Los Angeles outcome score, the radiological parameters and survival rates were assessed. The mean follow-up was for 5.4 years (4.0 to 8.1). All the...

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...
