Metatarsophalangeal joint arthroplasty is an accepted treatment for hallux rigidus. There are few reports of the long-term results of this procedure.
A series of 15 consecutive bio-action first metatarsophalangeal total joint replacements were retrospectively reviewed after a minimum follow-up of 5 years. The patients were assessed using the American Orthopaedic Foot and Ankle Society Score. Patient satisfaction and standard radiographs were also examined.
Subjectively, just over half the patients were satisfied with the results of the surgery. Objectively, however mechanical failure of the implant was universal, as determined radiographically.
Despite some success in relieving symptoms in patients, we have abandoned this procedure because of the high and increasing rate of failure, as demonstrated both clinically and radiologically.
跖趾关节置换术是治疗拇僵硬的一种公认的治疗方法。关于该手术的长期效果的报道很少。
对 15 例连续的生物动作第一跖趾关节全关节置换术进行回顾性研究，随访时间至少 5 年。采用美国矫形足踝协会评分对患者进行评估。同时检查患者满意度和标准 X 线片。
主观上，超过一半的患者对手术结果满意。然而，客观上，影像学显示，植入物的机械故障是普遍存在的。
尽管该手术在缓解患者症状方面取得了一定的成功，但由于临床和影像学均显示出高且不断增加的失败率，我们已经放弃了该手术。
