Degenerative changes of the scaphotrapezial trapezoidal (ST) joint commonly cause pain and weakness. These patients do not respond to conservative treatment, and for several years effort has been made to find an easy way to relieve symptoms. In a previous report a silicone interposition arthroplasty was described and considered to be a useful method. However, the durability of the elastomer was insufficient, and implant fractures and migration of fragments occurred. Since then the procedure has been modified, and high performance Silastic has been used for interposition. Ten patients have been reviewed, with a follow-up from 6 to 36 months (average 15 months). All patients have had lasting relief from pain and consider they have full hand function, without stiffness or limited thumb or wrist motion. Roentgenographic reviews have neither revealed deterioration nor dislocation or migration of the implant. Untoward bone reactions have not been observed. Implant hemiarthroplasty is indicated only when the degenerative changes are solely confined to the ST joint.
舟大多角小多角（ST）关节的退行性变常导致疼痛和无力。这些患者对保守治疗无反应，多年来一直在努力寻找一种缓解症状的简便方法。在之前的一份报告中描述了硅胶置入关节成形术，并认为这是一种有用的方法。然而，弹性体的耐久性不足，出现了植入物骨折和碎片移位的情况。从那时起，该手术方法已得到改进，高性能硅橡胶已用于置入。对10例患者进行了复查，随访时间为6至36个月（平均15个月）。所有患者的疼痛都得到了持久缓解，并认为他们的手部功能完全正常，没有僵硬或拇指及腕关节活动受限的情况。X线复查未发现植入物有恶化、脱位或移位。未观察到不良的骨反应。仅当退行性变仅局限于ST关节时，才考虑植入半关节成形术。
