The domed osteotomy has been successively performed for 4 cases with the varus deformity of the elbow joint in children, which was caused by the transcondylar or supracodylar fractures of the humerus.
The advantages of the new technique of the domed osteotomy against the varus deformity are as follows:
1. The correction in open operation is possible for the varus deformity, flexion disturbance and displacement of the internal or external rotation of the fracture region.
2. the correction of the radial prominence out of the humerus is able to perform by the displacement of the distal portion.
3. The extreme varus deformity is also able to correct, which is difficult in operated by usual wedge osteotomy.
4. By the wider cotact of cutting region as other methods, the bone union is more expected.
However, we understand that the method has some disadvantages such as the complicated operation technique, and possibilities of happend trouble of the ulnar nerve palsy by the increased tension of the ulnar nerve. But we prevent it by the ulnar nerve release, or shortning of the humerus.
