Between 1971 and 1982, thirty-three patients underwent scaphoid silicone arthroplasty, and twenty-three of them were available for review after an average of three years of follow-up. Radiographically, there was evidence of carpal collapse with a progressive decrease in carpal height and a progressive increase in the scapholunate angle in thirteen wrists. Subluxation of the spacer occurred in thirteen patients, and nine of them also had dislocation of the trapezial stem. Clinically, grip strength did not improve and wrist motion increased only slightly. There were complaints of pain associated with subluxation of the spacer in more than half of the patients. Ten patients, eight of whom had a subluxated spacer, underwent thirteen secondary surgical procedures.
1971年至1982年间，33例患者接受了舟状骨硅胶置换术，其中23例在平均随访三年后可供复查。影像学检查显示，13例腕关节出现腕骨塌陷，腕骨高度逐渐降低，舟月角逐渐增大。13例患者出现假体半脱位，其中9例还伴有大多角骨柄脱位。临床上，握力没有改善，腕关节活动仅略有增加。超过半数的患者抱怨假体半脱位伴有疼痛。10例患者接受了13次二次手术，其中8例患者的假体发生了半脱位。
