Slipped capital femoral epiphysis caused by an implant--a case report

A nine-year old boy sustained a traumatic fracture of the neck of left femur and was treated by closed reduction and cancellous screw fixation. Fourteen months later the tips of the screws were found to be at the epiphyseal plate and there was evidence of slip of the upper femoral epiphysis. The opposite hip was normal and no other abnormalities were detected. It is postulated that the slip was caused by the implant.
