[Hallux valgus. A prospective study of staple fixation in Mitchell's osteotomy].

Twenty-two feet (17 patients) with hallux valgus were operated with a distal osteotomy of the first metatarsal bone ad modum Hawkins, Mitchell and Hedrick (1945). Fixation of the osteotomy was achieved using two staples driven into the bone by a pneumatic stapler (3M). Postoperatively the patients were treated without plaster bandage in a heel-shoe for two weeks and then allowed full weight bearing. There were two superficial infections, but no deep ones. Within six weeks all the osteotomies had healed without any secondary dislocation. Two staples had to be removed in local anaesthesia after healing. Staple fixation gives adequate support during healing of the osteotomy and allows early mobilisation without the need of a plaster bandage.

[The reliability of fiber endoscopic estimation of the size of gastroduodenal ulcer].

The areas of 22 regions in a gastro-duodenal model were estimated endoscopically by 11 examiners. The procedure was then repeated with a biopsy forceps as the reference for measurement. Without the biopsy forceps, 86% of the areas were underestimated. Measurement with the biopsy forceps reduced the deviations of the estimates and the scatter of these but 75% were still underestimated. The estimates showed considerable inter-observer variation and limited reproducibility. Endoscopically estimated alteration in area of an ulcer should not be accepted as clinical documentation for healing.

[Pigmented villonodular synovitis].

Pigmented villonodular synovitis (PVS) is characterized by diffuse or localized proliferation of the synovial membrane in synovial joints, tendon sheaths or bursae. The etiology and pathogenesis are unknown. The condition is most frequently localized to the flexor tendon sheaths. Intraarticular PVS is most frequent in the knee joint. Swelling of the joint and slight pain develop. The localized intraarticular form may result in locking of the joint. The joint fluid is frequently haemorrhagic. The laboratory tests reveal normal findings. X-rays reveal erosion of the bone and cyst formation. Histological examination of the affected tissue is necessary to establish the diagnosis. Treatment consists of surgical excision. In the diffuse intraarticular form, this must take the form of total synovectomy. In cases with recurrence or pronounced destruction of bone, joint replacement may be indicated.

Epidemiology of proximal humeral fractures.

In an urban population of half a million, all proximal humeral fractures were recorded in 1983. A total of 565 fractures, of which 77 per cent occurred in women, were seen. The overall incidence per 100,000 was 48 in men and 142 in women, with an exponential increase from the 5th decade of age. This rise was due to a higher incidence of minimally displaced fractures associated with moderate trauma, and thus of fractures associated with osteoporosis.

Humeral shaft fractures treated with a ready-made fracture brace.

Twenty patients, 17 to 87 years of age, were treated with a dynamic brace for fractures of the humerus. The brace acts by compressing the soft tissues surrounding the fractured bone while the dependent arm of the ambulatory patient helps to pull the displaced bone fragments into normal relationship. As soon as the initial swelling and pain subsides the brace can be applied, usually within the first week. The brace permits early exercise of all the joints; it gives good comfort to the patient. There were two nonunions. Eighteen fractures healed with good anatomical and functional outcome.

Complications of fractures of the femoral neck.

The results of a series of 82 medial femoral neck fractures are presented. Complications arose in 34% of 24 non-operated impacted fractures (17% redisplacement, 17% necrosis of the femoral head). 58 patients were treated with a sliding screw plate device (Zimmer). The Garden stage I and II fractures united uneventfully. Out of a total of 52 Garden stage III and IV fractures, 14 (27%) had to be reoperated with total hip arthroplasty, due to redisplacement or necrosis of the femoral head. All redisplacements occurred in cases of unsuccessful reduction, indicating that quality of reduction is the prime determinant with regard to redisplacement. As all Garden stage I and II fractures, and 73% of the Garden stage III and IV fractures united, the material points at the gliding screw plate device as a most recommendable treatment in femoral neck fractures.
