掌板关节囊松解术治疗压砸伤术后掌指关节屈曲障碍

Volar plate joint capsule release for treatment of post-traumatic metacarpophalangeal joint flexion contracture caused by crush injury

目的探讨应用掌板关节囊松解术治疗手掌严重压砸伤造成的掌指关节屈曲障碍。方法2005年9月-2008年6月，应用掌板关节囊松解术治疗8例严重压砸伤术后掌指关节被动屈曲障碍的患者，并进行随访，结合蜡疗及功能锻炼观察掌指关节屈曲功能的恢复情况。结果8例患者均为第3掌指关节被动屈曲障碍，术后关节屈曲功能均获明显改善。屈曲失能角度（F）减小，达到0°～30°；失能值降低，达到0％-18％。结论应用掌板关节囊松解术治疗手掌严重压砸伤造成的掌指关节屈曲障碍，是一种操作简便、疗效可靠的良好方法。

Objective To discuss the application of volar plate joint capsule release to treat metacarpophalangeal joint flexion contracture caused by severe crush injury to the palm. Methods From September 2005 to June 2008, 8 cases with post-traumatic metacarpophalangeal joint flexion contracture caused by severe crush injury was treated with volar plate joint capsule release. Postoperatively the patients underwent keritherapy and functional exercise. They were followed up to evaluate recovery of metaearpophalangeal joint flexion. Results All 8 patients had metacarpophalangeal joint flexion eontraeture of the middle finger. The joint flexion function was improved remarkably after the surgery. The joint movement limitation decreased to 0° to 30°and the funetional impairment reduced to 0% to 18%. Conclusion Volar plate joint capsule release is an excellent method to treat metacarpophalangeal joint flexion contracture caused by severe palm crush injury. It is easy to operate and leads to reliable results.
