[In situ pinning with Kirschner wires for chronic juvenile slipped capital femoral epiphysis].

Fixation in situis the most common method of management for different degrees of slip of the proximal capital femoral epiphysis. The aim of our study is to retrospectively analyze final results and complications after in situ pinning with Kirschner wires for stabile slipped capital femoral epiphysis. We retrospectively reviewed clinical records and radiographs of 61 children (17 girls and 33 boys) at the average age of 11.8 years. The average follow-up period was 7.4 years, minimum 3 years. In slips 300 and less (38 hips) vast majority of patients had very good and good subjective results (pain and function), 5% and 8% has satisfactory objective (limping and range of motion) and radiological results respectively. In slips between 30-60 degrees (23 hips) 75%, 60% and 70% had satisfactory subjective, objective and radiological results respectively. One child had chodrolysis that resolved at later follow up. There was no case of AVN. In 6 cases wires migration was found. In situ spinning with Kirschnerwires is simple safe and gives satisfactory results. This method of treatment especially recommended in younger, skeletally immature children with remaining growth of femoral neck.
