Proximal interphalangeal (PIP) joint dislocation a common injury. Usually, concentric stable reduction can be achieved with closed reduction. Occasionally, PIP joint dislocations are irreducible and open reduction is necessary. Complications include prolonged splinting and delay in presentation with subluxation or persistent dislocation. Surgery is often recommended for contracture or joint reduction. Surgical techniques focus on contracture release, joint reduction, and range of motion. Techniques have evolved from primary repair to tenodesis and suture anchor reconstruction. Most studies on PIP joint dislocations are retrospective case reports with good outcomes but chronic mild contracture and deformity are consistent in the literature.
近端指间关节（PIP）脱位是一种常见损伤。通常，通过闭合复位可实现同心稳定复位。偶尔，PIP关节脱位无法复位，需要切开复位。并发症包括长期夹板固定以及半脱位或持续性脱位就诊延迟。对于挛缩或关节复位，通常建议手术治疗。手术技术侧重于挛缩松解、关节复位和活动范围。技术已从一期修复发展到腱固定术和缝线锚钉重建。大多数关于PIP关节脱位的研究都是回顾性病例报告，结果良好，但文献中慢性轻度挛缩和畸形较为一致。
