Thirty-three patients with 39 Swanson silastic trapezium implants have been studied. Three years after operation no dislocation or evidence of implant wear was found, but re-examination at an average of 12 years after operation revealed dislocations and implant wear in about half of the cases. Cyst formation in surrounding carpal bones was found in twenty cases. The result in terms of pain relief and thumb function was good and comparable to the three-year follow-up. A significant correlation was found between weakness of the pinch grip and dislocation of the implant. No correlation was found between pain and dislocation of the implants, nor between pain and presence of intraosseous cysts.
对33例植入39个斯旺森硅橡胶梯形植入物的患者进行了研究。术后三年未发现脱位或植入物磨损迹象，但平均术后12年复查发现约一半病例出现脱位和植入物磨损。20例患者周围腕骨出现囊肿形成。在缓解疼痛和拇指功能方面效果良好，与三年随访结果相当。发现捏力减弱与植入物脱位之间存在显著相关性。未发现植入物脱位与疼痛之间、以及疼痛与骨内囊肿的存在之间存在相关性。
