The results of secondary microsurgical repair of ulnar nerve injury.

110 patients with injuries to the ulnar nerve were assessed, on average, 12.7 (3-20) years after secondary repair. 89 were male and 21 female, with a mean age of 27.

The results of secondary microsurgical repair of radial nerve in 33 patients.

33 patients with injuries to the radial nerve were reviewed, on average, 12.1 (5-20) years after secondary repair. 24 were male and nine female, with a mean age of 29.

Cementless total replacement for severely dysplastic or dislocated hips.

We report the short-term results of 100 cementless total hip replacements in 52 severely dysplastic and 48 totally dislocated hips, with some new technical solutions to the problems involved. In cases with a very narrow iliac bone, the acetabular screw ring is seated below the true cotyloid area. In hips with tight flexor and abductor muscles or with deformities of the proximal femur, various osteotomies were performed.

Vascularized pedicled bone graft into the femoral head--treatment of aseptic necrosis of the femoral head.

Revitalization of the femoral head in cases of aseptic necrosis was attempted in 13 hips of 11 patients 15-33 years of age. The necrotic bone was replaced by a vascularized pedicular iliac bone graft and free cancellous transplants. The results after an average follow-up of 53 months are satisfying in some cases.
