Prosthesis survivorship and clinical outcome of the Austin
Moore hemiarthroplasty: an eight-year mean follow-up of a consecutive series of
500 patients Abstract: The Austin Moore hemiarthroplasty prosthesis is inexpensive and is increasingly being used as a treatment for intracapsular hip fractures in developing countries. We report the results of a consecutive series of 500 patients treated with Austin Moore hemiarthroplasty prosthesis for hip fracture. The range of follow-up was from 5 – 12 years and the mean was 8 years. Only ten patients were lost to follow-up and 398 (81%) patients died within the follow-up period. The mean age of the patient population was 82 years, and 85% were women. The cumulative survivorship of the prosthesis was calculated at 94% (95% confidence interval 90%-96%) at 5 years and 83% (95% CI 65%-94%) at 12 years. A total of 66 secondary operations of any type were required in 46 (9%) patients. Revision of the Austin Moore prosthesis was performed in 23 cases (5%). Of the long-term survivors contacted for follow-up, 66 (81%) had no pain or minimal pain, whilst 5 (6%) reported constant in the hip. The revision rates in our series were higher for younger patients those from their own home and with good pre-fracture mobility and mental function. For the frail elderly with a displaced intracapsular fracture this prosthesis can still be recommended. This paper presents the largest consecutive series, with the longest follow-up currently available. |
