Plantar plate rupture is a common cause of forefoot pain, multiplanar malalignment, subluxation, or dislocation of the metatarsophalangeal joint (MTPJ). The treatments that have been described for MTPJ instability of lesser toes include amputation, lengthening and/or tendon transfer, periarticular soft-tissue release (capsule, collateral ligaments, and plantar plate), colateral ligament reconstruction, metatarsal shortening osteotomy, and suture of plantar plate lesion. This article outlines the anatomy, pathogenesis, and diagnosis of plantar plate rupture, and describes a new technique that combines joint decompression by Weil osteotomy with a plantar plate repair using a pull-out technique.
跖板破裂是前足疼痛、多平面排列不齐、跖趾关节（MTPJ）半脱位或脱位的常见原因。针对小趾MTPJ不稳定所描述的治疗方法包括截肢、延长和/或肌腱转移、关节周围软组织松解（关节囊、侧副韧带和跖板）、侧副韧带重建、跖骨缩短截骨术以及跖板损伤缝合术。本文概述了跖板破裂的解剖结构、发病机制和诊断方法，并描述了一种新技术，该技术将Weil截骨术的关节减压与采用拔出技术的跖板修复相结合。
