Two different or general types of arthroplasty for treatment of the saddle-joint-arthrosis are usual: particular bone-resection (base of first metacarpal or part of the trapezium) or complete resection of the trapezium, both combined with an interposition. The last one is essentially used in carpometacarpal arthroplasty. Two main groups are known: tendon-interposition and silastic prostheses. Most authors describe the dislocation of the first metacarpal, followed by pain and instability, in 20% of all cases. Neglecting of the ligament conditions seems to be the mainfault. In nearly all cases the ligaments can be found destroyed or elongated. Functional reconstruction is difficult or impossible, therefore a tendon-plasty should be done to restore the function of the ligaments. Some other mistakes and complications are reported. Planning a saddle-joint-arthroplasty they should be known as the best protection against bad results.
特定的骨切除术（第一掌骨基部或大多角骨的一部分）或大多角骨的完全切除术，两者均联合植入物。最后一种主要用于腕掌关节成形术。已知有两个主要类别：肌腱植入和硅橡胶假体。大多数作者描述，在所有病例中有20%会出现第一掌骨脱位，随后出现疼痛和不稳定。忽视韧带状况似乎是主要错误。几乎在所有病例中，都能发现韧带受损或拉长。功能重建困难或无法进行，因此应进行肌腱成形术以恢复韧带功能。还报告了一些其他错误和并发症。在计划进行鞍状关节成形术时，应了解这些情况，这是防止出现不良结果的最佳保障。
