Eight silastic implants of the lunate bone were inserted between 1980 and 1984 on 8 patients. Seven patients were seen, at a ten year follow-up visit and were satisfied with the results. However, STT osteoarthritis secondary to the carpal collapse had to be stabilized by a triscaph arthrodesis. The clinical course showed a clear improvement of force and mobility in a first phase, followed by progressive deterioration ending in a return to preoperative values. Multiple intracarpal cysts were found radiologically in all wrists as well as in the distal radius in two cases and in the metacarpal bones in 3 cases. The height of the prosthesis was decreased by about 36%. Carpal collapse and ulnar translation showed a statistically significant progression. According to these findings, silastic prostheses should no longer be recommended.
1980年至1984年间，为8例患者植入了8个硅橡胶月骨假体。7例患者在10年随访时接受了检查，对结果感到满意。然而，腕骨塌陷继发的舟月三角关节骨关节炎必须通过舟状骨间关节融合术来稳定。临床过程显示，第一阶段力量和活动度明显改善，随后逐渐恶化，最终恢复到术前水平。所有手腕在影像学上均发现多个腕骨内囊肿，2例桡骨远端和3例掌骨也发现囊肿。假体高度下降了约36%。腕骨塌陷和尺侧移位在统计学上有显著进展。根据这些发现，不再推荐使用硅橡胶假体。
