Between 1993 and 2002, 165 corrective osteotomies in 152 patients were performed with the interlocking nail in the lower extremity. The method of intramedullary stabilisation of long tubular bones of the legs has the big advantage of early full weight bearing in combination with a covered osteosynthetic technique and stable dynamic biomechanic inducing biological bone healing with callus formation. In contrast to the ordinary ways of osteotomy there is no need to perform the correction in the level of metaphysis as other methods of bone fixation with plates or fixateurs interfere with bone concolidation in the diaphysis. Because of the drilling sludge any further bone grafting could be delected in case of defects which are not bigger than 2 cm. Even in cases of biaxial or multidimensional deformities only a short oblique osteotomy is necessary. The longer fragment of the bone is guided by the nail and the shorter fixed by the interlocking screws against rotation and bending. With gamma nail intertrochanteric osteotomies were performed as well. The results showed complications in 9 cases: 4 infections in the tibia of which all could be treated with success after early nail removal and redilling with the drainage, 3 peroneal palsy without complete recovery and 2 non-unions which needed bone grafting. A slight loss of correction were seen in 12 cases, but not more than 5 degrees of axis or 1 cm of length. Because of the results the method is now the standard for all classical forms of correction in the intertrochanteric, supra- and infracondylar level of femur and tibia as well as the supramalleolar level. In 3 patients both femora had been corrected, in one case both femora and tibiae, in 7 both tibiae.
