We performed a retrospective review of Sutter silicone metacarpophalangeal (MP) joint arthroplasties in 34 patients (42 hands, 168 implants) with rheumatoid arthritis. Patients were evaluated at an average of 27 months (minimum follow-up period, 12 months). Twenty percent of the implants were shown to be definitely fractured on final follow-up examination, and 45% followed for more than 3 years were definitely fractured. At the final follow-up examination, the average ulnar drift in intact implants was 11 degrees and in the fractured implants, 23 degrees. However, there was no correlation between implant fracture and patient satisfaction. Eighty percent of patients said they would undergo the procedure again. Because of a significantly higher implant fracture incidence at a relatively shorter follow-up period than that of most studies of silicone MP implants of the Swanson design, we have abandoned the use of the Sutter implant.
我们对34例类风湿性关节炎患者（42只手，168枚植入物）的萨特硅胶掌指（MP）关节置换术进行了回顾性研究。患者平均随访27个月（最短随访期为12个月）。在最终随访检查中，20%的植入物被明确显示发生骨折，在随访超过3年的患者中，45%的植入物被明确显示发生骨折。在最终随访检查时，完整植入物的平均尺偏为11度，骨折植入物的平均尺偏为23度。然而，植入物骨折与患者满意度之间没有相关性。80%的患者表示他们愿意再次接受该手术。由于在相对较短的随访期内，萨特植入物的骨折发生率明显高于大多数关于斯旺森设计的硅胶MP植入物的研究，我们已不再使用萨特植入物。
