We have made a retrospective study of 1001 custom-made prostheses used as replacements after surgery for bone tumours. There were 493 distal femoral, 263 proximal femoral and 245 proximal tibial prostheses. Aseptic loosening was shown to be the principal mode of failure of the implants, and 71 patients had revision for aseptic loosening of a cemented intramedullary stem. The probability of a pa...

Disruption of the proximal femoral epiphysis in the neonate is a rare injury, and requires to be differentiated from congenital dislocation of hip, osteomyelitis of proximal femur and fracture of the proximal femoral metaphysis. The proximal femoral epiphysis in the neonate is not visible in an X-ray. Therefore, diagnosis of its disruption is not easy. Radiological changes do occur in the proxi...

Proximal focal femoral deficiency (PFFD) is a developmental disorder of the proximal segment of the femur and of acetabulum resulting in shortening of the affected limb and impairment of the function. It is a spectrum of congenital osseous anomalies characterized by a deficiency in the structure of the proximal femur. The diagnosis is often made by radiological evaluation which includes identif...

We followed prospectively 69 patients with 78 proximal femoral allografts performed for revision of total hip arthroplasty for an average of 36 months (range 29 to 68). Large fragment proximal femoral allografts and cortical strut allografts were successful in 85%. Grafts smaller than 3 cm in length (calcar grafts) were clinically successful in 81%, but 50% underwent significant radiographic re...

INTRODUCTION Hip fractures are very common in adults, but are rare in children, comprising less than 1% of all pediatric fractures. Separation of the proximal femoral epiphysis can occur in a child with a traumatic hip dislocation and an open epiphysis. Regardless of the mechanism of proximal femoral epiphyseal separation, the prognosis is poor secondary to the development of osteonecrosis. C...
