The treatment of rhizarthritis involves several surgical techniques; among them, bioabsorbable scaffolds have begun to be proposed to avoid the use of other biological tissues or artificial permanent devices. In this study, we evaluated the long-term outcomes of poly-ld-lactic acid scaffold in interposition arthroplasty in a series of patients treated in our department. Strength, range of motion, and pain improved after the intervention and lasted over the years; nonetheless, most of the radiographs showed a progressive collapse of the first metacarpal. Despite radiological findings, we believe that poly-ld-lactic acid scaffold can be considered a good alternative to traditional trapeziectomy with tendon interposition and suspensionplasty, with long-lasting satisfactory clinical results.
rhizarthritis 的治疗涉及几种手术技术；其中，生物可吸收支架已开始被提议用于避免使用其他生物组织或人工永久性装置。在这项研究中，我们评估了在我们科室治疗的一系列患者中，聚乳酸支架在间置关节成形术中的长期效果。干预后力量、活动范围和疼痛得到改善，并持续多年；然而，大多数 X 光片显示第一掌骨逐渐塌陷。尽管存在放射学发现，但我们认为聚乳酸支架可以被认为是传统的梯形切除术与肌腱间置和悬吊成形术的良好替代方案，具有持久的满意的临床效果。
