拇指腕掌（CMC）关节骨关节炎（OA）有几种手术选择。本文介绍了我们对10例患者12个拇指的长期临床和影像学回顾，这些患者接受了部分桡骨切除和硅橡胶间置关节成形术。随访期平均为15年，最短为10年。虽然该手术在大多数拇指中提供了早期疼痛缓解，但在随访时，除了两个拇指外，所有拇指都有轻度至重度疼痛。术后掌外展范围平均23.术后平均握力为9.5 kg。拇指和食指之间的指尖和关键捏平均约为正常受试者的50%。植入物脱位发生在两个关节和断裂在五个。在四个拇指中发现植入物周围的骨质侵蚀，我们将其归因于硅胶滑膜炎。拇指CMC关节OA的硅橡胶间置关节成形术的适应症应严格限制，因为这些手术的长期结果不令人满意。
There are several surgical options for osteoarthritis (OA) of the thumb carpometacarpal (CMC) joint. This paper presents our long-term clinical and radiographic review of 12 thumbs in ten patients treated by partial trapezial excision and silicone-rubber interposition arthroplasty. The follow-up period averaged 15; three years with a ten-year minimum. Although the procedure provided early pain relief in most thumbs, all but two had mild to severe pain at follow-up. The average range of post-operative palmar abduction was 23.. The average post-operative grip strength was 9.5 kg. Both tip and key pinch between thumb and index finger averaged about 50% that of normal subjects. Dislocation of the implant occurred in two joints and breakages in five. Bony erosions around the implant, which we attributed silicone synovitis, were found in four thumbs. The indications for silicone-rubber interposition arthroplasty for OA of the thumb CMC joint should be severely restricted as these produced unsatisfactory long-term results.
