A New Modified Operative Technique for Varus or Valgus Deformity of Knee and Elbow Joint

Abstract

It has been generally accepted that the osteotomy corrects the varus or valgus deformity of the knee and the elbow joint for relief from pain. The technique which removes wedgewidely the bone at the proximal tibia or distal humerus has been usually available for correction. We tried a new modified technique to correct the deformity by the Z like frontal osteotomy and the following results were obtained. The results of this technique were excellent in the case of osteoarthritis of the knee joint. Contrary to the wedge osteotomy, this procedure could be done very easily with firm internal fixation. The bone union was accomplisshed quickly because of the wide osteotomized surface and the sufficient correction could be achieved near the joint surface. In the elbow joints, the step-formation on which was made on the osteotomized level was not found by this procedure. Some problems to be improved in this new modified technique were still remained. How is it done, for example, safer and firmer for the internal fixation?
