Functional outcome of cemented austin moor hemiarthroplasty for treatment of neck femur fracture in elderly.

BACKGROUND

Femoral neck fractures in elderly patients are associated with significant morbidity and mortality. Treatment options include internal fixation, hemiarthroplasty, and total hip arthroplasty, with the Austin Moore prosthesis representing a cost-effective choice in resource-limited settings.

PURPOSE

To assess the efficacy and safety of the cemented Austin Moore prosthesis in elderly, low-demand patients with femoral neck fractures in a resource-limited setting.

METHODS

This prospective study included 52 patients aged over 65 years who underwent hemiarthroplasty with the Austin Moore prosthesis between January 2020 and January 2022 at Amran General Hospital, Yemen. Functional outcomes were assessed using the Harris Hip Score (HHS) and the Parker and Palmer Mobility Score at 1, 3, 6, 12, and 24 months postoperatively.

RESULTS

Forty-nine patients completed the 24 month follow-up. The mean age was 75.8 years, with a male-to-female ratio of 0.69:1. The mean HHS at 2 years was 85.4; 16.3% of patients achieved excellent outcomes, 55.1% good, 20.4% fair, and 8.2% poor. The Parker and Palmer Mobility Score indicated that 71.4% of patients had a score greater than 5. Postoperative complications included superficial infections (4%), deep-vein thrombosis (8.1%), and mild limb length discrepancy (6.2%).

CONCLUSION

Hemiarthroplasty using the Austin Moore prosthesis is a cost-effective and reliable treatment for femoral neck fractures in elderly patients, providing good functional outcomes and a low complication rate in resource-limited settings.
