摘要

拇僵直是足部最常见的关节炎病理，是一种使人衰弱的疾病，引起疼痛、肿胀和活动范围缩小。虽然关节融合术是金标准的治疗选择，但软半关节置换术植入物，聚乙烯醇(PVA)水凝胶，已被设计用于保持第一跖趾关节的活动并减轻疼痛。由合成PVA和生理盐水制成的指数非劣效性试验显示了满意的临床结果。然而，由于种植体下沉是一个普遍的问题，这一结果并没有被其他人重复。在这项手术技术中，我们描述了一种新的改良入路，包括第一跖趾关节的PVA半关节成形术，三维打印底板和Akin截骨术，以最终防止可能的种植失败。

Polyvinyl Alcohol Hydrogel Hemiarthroplasty of the First Metatarsophalangeal Joint Augmented With 3D-printed Baseplate

Hallux rigidus is the most common arthritic pathology of the foot and is a debilitating disease that causes pain, swelling, and reduced range of motion. Although arthrodesis is the gold standard treatment option, a soft hemiarthroplasty implant, the polyvinyl alcohol (PVA) hydrogel, has been designed to preserve motion in the first metatarsophalangeal joint and alleviate pain. Made from synthetic PVA and saline, the index noninferiority trial showed satisfactory clinical outcomes. However, this result was not reproducible by others with implant subsidence being a common concern. In this surgical technique, we describe a novel modified approach which involves PVA hemiarthroplasty of the first metatarsophalangeal joint, 3-dimensional-printed baseplate and Akin osteotomy to ultimately prevent likely implant failure.
