Abstract
Aim: To assess the functional outcome and longevity of patients who are mentally competent when they sustain an intra-capsular fracture of the femoral neck.
Methods: Prospective cohort study of fifty female patients over the age of seventy years of age with a displaced intra-capsular fracture of the femoral neck. Patients with known, cognitive impairment terminal illness or active infection were excluded from the study. Patients were treated with a large head total hip replacement. Functional outcome was assessed using the the Barthel index score and the Charnley-modified Merle d’Aubigne score yearly for five years. The Oxford hip score was also recorded annually from three to ten years post op. The date and cause of death were recorded from hospital notes and death certificates.
Results: The mean age at time of femoral neck fracture was 81 years. Three patients died before discharge from hospital. The mortality rates were 18% at twelve months, 28% at two years, 44% at five years and 92% at ten years. Those patients surviving had mean Oxford scores of 24 at 3 years, 26 at 5 years, 23 at 7 years and 25 at ten years. The cause of death was ischaemic heart disease in 22%, cancer in 10%, bronchopneumonia in 12% and simply ‘old age’ in 14%.
Conclusion: Elderly female patients who are not cognitively impaired at the time of displaced intra-capsular fracture of the femoral neck have a 56% chance of living five years. Function scores in the survivors are maintained, and are better than would be expected if the patients had undergone hip hemiarthroplasty. Total hip replacement in this population may be justified.
