The results of a consecutive series of 500 patients treated with Austin Moore hemiarthroplasty prosthesis are reported. The range of follow-up was from 5-12 years and the mean was 8 years. Only 10 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% CI 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 pain 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.
报告了连续500例接受奥斯汀·摩尔半关节置换假体治疗患者的结果。随访时间为5至12年，平均为8年。仅10例患者失访，398例（81%）患者在随访期内死亡。患者群体的平均年龄为82岁，85%为女性。假体的累积生存率在5年时计算为94%（95%可信区间90 - 96%），在12年时为83%（95%可信区间65 - 94%）。46例（9%）患者共需要进行66次任何类型的二次手术。23例（5%）患者进行了奥斯汀·摩尔假体翻修。在接受随访的长期存活者中，66例（81%）无疼痛或疼痛轻微，而5例（6%）报告髋部持续疼痛。在我们的系列研究中，年轻患者、在家居住且骨折前活动能力和心理功能良好的患者翻修率较高。对于伴有囊内移位骨折的体弱老年人，仍可推荐使用这种假体。本文呈现了目前可获得的最大连续系列病例及最长随访时间的研究。
