Osteoarthritis at the base of the thumb is a functionally disabling condition and, as such, the basal joint complex represents the most commonly operated focus in the osteoarthritic upper extremity. Degenerative disease is predicted on instability of the trapeziometacarpal joint secondary to deterioration of the capsular and ligamentous restraints. Ligament reconstruction in the setting of a symptomatic hypermobile joint with intact cartilage surfaces may retard progression of arthritic disease. Complications related to silicone implant arthroplasty have given way to ligament reconstruction tendon interposition arthroplasty as the preferred procedure for the osteoarthritic thumb basal joint complex.
拇指基部的骨关节炎是一种功能致残性疾病，因此，掌指关节复合体是骨关节炎上肢最常进行手术的部位。退行性疾病是由于关节囊和韧带限制结构恶化导致的大多角骨掌骨关节不稳定所引发的。对于软骨表面完好的症状性活动过度关节，进行韧带重建可能会延缓关节炎疾病的进展。与硅胶植入关节成形术相关的并发症已被韧带重建肌腱嵌入关节成形术所取代，成为治疗骨关节炎拇指基部关节复合体的首选手术方法。
