Primary arthritis of the thumb saddle joint is very common. Among the different treatment options, the implantation of a total joint arthroplasty is an alternative. The GUEPAR prosthesis, developed by a group of French surgeons, is mainly used in elderly patients and only in cases with preserved trapezial height. This study reports the mid-term results of the second generation of this implant. The clinical results show good pain relief and good mobility of the thumb. There were a few patients with radiological signs of implant loosening, but none of them had clinical problems. The advantage of a total replacement of the saddle joint, compared to the standard resection arthroplasty, is faster rehabilitation and preservation of the length of the thumb. The new generation of the GUEPAR prosthesis has a more anatomical metacarpal stem and a modularity which allows the fit of the implants according to the anatomical situation.
拇指鞍状关节原发性关节炎非常常见。在不同的治疗选择中，全关节置换术是一种替代方案。由一组法国外科医生研发的GUEPAR假体主要用于老年患者，且仅适用于保留大多角骨高度的病例。本研究报告了该植入物第二代的中期结果。临床结果显示疼痛缓解良好，拇指活动度良好。有少数患者出现假体松动的放射学迹象，但均无临床问题。与标准切除关节成形术相比，鞍状关节全置换的优势在于康复更快且能保留拇指长度。新一代GUEPAR假体具有更符合解剖结构的掌骨干以及模块化设计，可根据解剖情况适配植入物。
