1. Fifty dislocations and fracture-dislocations of the pelvis have been reviewed. 2. Complications were unusual. Two patients with rupture of the bladder died; two with rupture of the urethra survived. Of eight patients with retroperitoneal haemorrhage four died; the treatment advised is controlled blood transfusion maintaining a blood-pressure of not more than 100 mm. 3. Two types of pelvic disruption should be distinguished: 1) pubic injury with sacro-iliac dislocation; 2) pubic injury with fracture near the sacro-iliac joint. The first is twice as common as the second. 4. In each type, displacement is maintained by extension of the hip and outward roll of the limb. This may be controlled by the Watson-Jones plaster method but the pelvic sling technique is preferred and was used in all cases in this series. 5. The prognosis in fracture-dislocations is very good; nearly all patients went back to heavy work. 6. The prognosis in sacro-iliac dislocations is not so good; only half the patients went back to heavy work and there was often persistent sacro-iliac pain. Sacro-iliac arthrodesis is advised in those cases

Aims

Limb salvage for pelvic sarcomas involving the acetabulum is a major surgical challenge. There remains no consensus about what is the optimum type of reconstruction after resection of the tumour. The aim of this study was to evaluate the surgical outcomes in these patients according to the methods of periacetabular reconstruction.

1. Three cases of severe retroperitoneal haemorrhage complicating fractures of the pelvis are described. In two patients haemorrhage was immediately controlled by ligation of the internal iliac artery. The third patient died before the bleeding could be controlled. 2. Ligature of the internal iliac artery may be a life-saving measure when fracture of the pelvis is complicated by severe haemorrhage

1. Seventy-five patients sustained fractures of the pelvis with associated soft-tissue complications. Twenty died, and of these, thirteen died within forty-eight hours of admission to hospital. 2. The initial resuscitation and clinical assessment of these patients are discussed, and attention is drawn to the significance of the concomitant retroperitoneal haematoma as a cause of oligaemic shock, and as a dissembler of internal visceral injury. 3. The morphological fracture patterns are classified into six categories, but the fracture patterns are not correlated with specific visceral injuries. 4. Forty-six patients sustained urinary tract injuries. Of these, nineteen had suffered rupture of the urethra; fourteen had rupture of the bladder; two had both urethral and vesical disruption, and one patient had a torn ureter. The diagnosis and management of these injuries is discussed. 5. Twelve patients had a traumatic laceration or perforation of the ano-rectum. Nine of these patients had associated urethral or vesical injuries. 6. Four patients were involved in accidents and sustained pelvic fractures while in the last three months of pregnancy. The tragic outcome of this combination of circumstances is noted. 7. Attention is drawn to peripheral nerve injuries in association with pelvic fractures, and the difficulty of localising these lesions is stressed. 8. Eight instances of damage to the abdominal parietes are recorded. Four patients suffered skin and soft-tissue loss, two patients had diaphragmatic disruptions and two patients had abdominal wall dehiscences. 9. Major accident victims frequently have multiple injuries. This series of patients has been analysed to draw attention to the association of pelvic fractures with bizarre visceral injuries

We reviewed 43 patients treated from 1984 to 1988 for open fractures of the pelvis. There were four Gustilo type I wounds, seven type II and 32 type III; 22 fractures were stable and 21 unstable. The overall mortality was 30%; the average Injury Severity Score was 30, being 26 in the survivors and 40 in the fetal cases. We analysed the influence of a number of factors on the mortality rate. The most important were the ISS and the age in years, while the presence of a type III wound and instability of the fracture also had an influence. We describe two simple methods of assessment of the prognosis in individual cases, based on these factors

We report a patient with a peri-acetabular chondrosarcoma which was treated by resection of part of the pelvis and the femoral head. This was followed by replacement with a custom-made titanium alloy pelvic portion and a conventional total hip prosthesis. The operation was carried out in two stages, and yielded a good functional and cosmetic result
