Abstract
Introduction and Aims: Severe central fracture dislocations of the hip in the elderly can be catastrophic events. Conservative treatment yields poor results with stiff painful hips. We assessed the results of three patients treated with a total hip replacement for a central fracture dislocation of the hip, using ante-protrusio supports and bone grafts.
Method: Three elderly patients with central fracture dislocations were treated with early total hip replacement utilising ante-protrusio supports. Bone grafting was used to re-establish acetabular bone stock. Intra and post-operatively these patients had no more complications than a comparable group undergoing hip replacement for femoral neck fractures. The surgical times were longer than for routine hip replacment, and blood replacement requirements was slightly higher. Patients were mobilised early and aggressively.
Results: All became independent walkers. All regained a good range of movement. Radiologically the acetabular/pelvic fractures united and good bone-implant interfaces were obtained. There was no excessive heterotrophic bone formation. The economic assessment indicated that it was more cost-effective to treat these patients with a hip replacement than with alternative methods.
Conclusion: We regard total hip replacements in the management of acetabular fractures in the elderly as a reasonable approach, enabling our patients to mobilise early and keeping morbidity to an acceptable level. The procedure is also more cost-effective than internal fixation and delayed arthroplasty.
