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.

Results of treatment of aseptic necrosis of the femoral head with vascularized bone graft.

Osteonecrosis of the femoral head with deformity was treated with vascularized iliac crest grafts or with free microanastomosed fibular grafts in 20 young adults (22 hips). The clinical and radiographic results at two years and five years are presented. The overall results are promising.

Construction of acetabular bone stock. A staged cementless arthroplasty of the hip.

Vascularized pedicular bone graft was used for the purpose of achieving a sufficient bone stock for cementless total hip arthroplasty in patients with major acetabular bone defects. A useful bed for the acetabular prosthesis was obtained in all three cases. The ordinary prosthetic arthroplasty was performed in the second phase.

Silicone implant arthroplasty in Kienböck's disease.

Fifty-five patients with malacia of the carpal lunate treated by Swanson's silicone implant arthroplasty were reexamined. The follow-up period averaged 3 years. The operation had a favorable effect on pain, but the range of motion and the grip strength remained impaired.

Dynamic reconstruction of the cruciate ligaments of the knee.

This paper reports the long term results of dynamic gracilis or semitendinosus transfer in chronic cruciate ligament instability of the knee. During the period 1968-1983, 76 dynamic reconstructions were performed. Sixty-one patients (63 knees) were evaluated.

Osteotomy of the neck of the humerus for traumatic varus deformity.

Seven patients had osteotomy for traumatic varus deformity of the humeral neck following fracture. Indications for the operations were limited active abduction and forward flexion of the arm. The result was good in five cases.

Surgery of the brachial plexus.

The principles and difficulties of surgery of brachial plexus lesions in 52 cases are reported. In 22 cases there was avulsion of one or more roots. Six lesions were infraclavicular.

Accessory nerve injury.

A series of 13 patients with an injury of the accessory nerve in the posterior cervical triangle is reported. In 11 patients the nerve was damaged during a lymph node biopsy and in two cases there was a sharp glass injury. Paralysis of the trapezius muscle occurred with resulting deformity and loss of function of the shoulder.

Reconstruction of the rotator cuff.

The results of a new operative technique of reconstruction of the rotator cuff are described in 112 cases. The principle of the method is the restoration of the anatomy in order to restore function. Results so far have been encouraging, as 80% of the patients have benefited from the operation.

Bone cysts containing silicone particles in bones adjacent to a carpal silastic implant.

Silastic implants for a wide variety of medical purposes are in current and frequent use worldwide. Only recently there have been reports of the migration of silicone to the surrounding tissues via lymphatics. In the present material of nine cases with carpal implants followed for more than two years, bone cysts developed in the surrounding bones on five occasions.

Transposition of pedicled skin flaps in the hand.

A series of 28 neurovascular island flaps are presented together with a series of three radial innervated pedicled flaps. The former method gave superior results compared to the latter. The mean follow-up period was 4.

Toe to hand transfer.

Nine patients received a toe-to-finger transfer after accidental amputation and one after a congenital defect. One led to secondary amputation due to arterial thrombosis. Seven of the 9 patients would have the operation again if needed.

Arteriography before toe to hand free tissue transfer operation.

During the last two years the hand surgeons performed toe to hand transfer operations on eight patients. Preoperative hand and foot arteriography was carried out in all cases. This is important in order to determine which arteries can be used and which toe should be selected for the transfer.
