Slipped capital femoral epiphysis: intraarticular position of devices. - Bad results and clinical consequences

Which consequences can be ascribed to the intraarticular position of device s in the operative treatment of a slipped capital femoral epiphysis? Which steps are to define as a standard of a careful procedure? The clinical and radiological results of five cases of a pin or nail penetr ation after the operative treatment of a slipped capital femoral epiphysis are described, a possible connection of causalities is investigated. The in traarticular position of devices in most cases goes along with an unfortuna te clinical outcome and leads to a higher risk of developing chondrolysis. Because of the radiologic overprojection with the femoral head it is possib le to oversee the malposition of the pin. Any operative treatment of a slip ped capital femoral epiphysis requires a careful intraoperative X-ray exami nation combined with documentation. With this procedure the bad results of an intraarticular implant position must be ascribed to the reminding risk o f a fateful development.
