Encounters with pseudoaneurysms in orthopaedic practice.

Thirteen pseudoaneurysms are presented of which five were caused as a complication of pin/wire placement of external fixators (one conventional and four Ilizarov frames). The most common symptom was the presence of profuse persistent bleeding from either the wound or the pin/wire site. In nine patients the pseudoaneurysm was directly caused by a fracture or subsequent fracture stabilisation. Pre-operative evaluation included radiography, arteriography, Doppler and computed tomography (CT) angiography. Depending on the site and size of the pseudoaneurysm management consisted of either ligation, resection and end-to-end anastamosis/vein grafting, lateral suture, endoaneurysmorrhaphy or selective embolisation.A high index of suspicion needs to be maintained following penetrating injury in the vicinity of a major vessel, particularly in the presence of persisting symptoms. External fixators are widely used to treat complex orthopaedic problems. The procedure is technically demanding, requiring a sound knowledge of cross-sectional limb anatomy. Injudicious use may result in potentially life/limb threatening complication of pseudoaneurysm.

Giant cell tumour of soft tissue--a case report.

Giant cell tumor is seen in late adolescence or in the third or fourth decade of life. It arises from epiphysis of long bones, the commonest site being the distal end of the demur and the proximal end of tibia. This paper presents a case report of giant cell tumor of soft tissue.

Biological fixation of subtrochanteric fractures by external fixation.

Fifty-one subtrochanteric fractures have been stabilized by external fixation over the last 9 years. Union occurred in all types of fractures, usually within 6 months. Soft tissue interposition led to non-union in three patients. Refracture in one patient and significant limb-length discrepancy in two patients was seen. The technique is versatile, easily reproducible and 'biological'. Protected weight-bearing is not necessary after removal.

Salvage of limbs with vascular trauma.

In an eight-year period we treated 51 cases of vascular injury associated with fractures and/or dislocations or soft-tissue injuries of the limbs. We relied on a clinical diagnosis and immediate exploration of blood vessels rather than the time-consuming procedure of arteriography. All patients were operated on by the orthopaedic residents on duty and not by vascular surgeons. Only 17 (33%) were repaired within six hours of injury. Limb viability with good function was obtained in 38. Complications included six deaths, four amputations, two renal failures and delayed occlusion in one case.

External fixation of intertrochanteric fractures of the femur.

External fixation was used in the treatment of 154 intertrochanteric fractures of the femur over a period of eight years. Good fixation and early ambulation was achieved in all cases. Blood loss was slight. There were 12 deaths due to medical causes unrelated to the surgical procedure. Deep pin-track infection occurred in six cases and late displacement of the fracture fragments in nine. The average time for union was 16 weeks. The technique is simple, quick and inexpensive, and causes minimal surgical trauma. All these features are particularly relevant where resources are limited.
