[Double intertrochanteric distraction osteotomy.].
The authors present four case-histories pertaining to double intertrochanteric distraction osteotomy of the proximal portion of the femur. In two female patients the result was excellent, in one female patient a 130 degrees splint broke and in another the splint was bent and the splints had to be replaced. All patients are satisfied with the operation because the extremity was prolonged on average by 2 cm. The authors objective is to demonstrate, based on their own practice, the static and biomechanical demands laid not only on bone but also on the metal fixation material (splint) in double distraction osteotomy of the proximal femur. Based on these observations the authors recommend in double distraction osteotomy of the proximal femur in adults prolonged immobilization of the hip joint either in bed with extension applied for four weeks or use of a plaster spike for a four-week period. Key words: dysplasia of the hip joint, intertrochanteric distraction osteotomy.
