BACKGROUND
Many solutions have been proposed in treating of forearm supination. Comparing with other supination function reconstructions, pronator teres rerouting is believed to be less effective due to its insufficient supination strength. The aim of this study is to introduce a modified procedure, and compare its result with two previous approaches.
PATIENTS AND METHODS
From 2015 to 2020, 11 patients have restored forearm supination by rerouting of the pronator teres weave sutured with allogeneic tendons. The average follow-up period was 17.5 months (12 to 24). The range of active supination at the final follow-up was recorded.
RESULTS
Almost all patients acquired good supination range. The average active post-operative supination was 72.7° (60° to 80°) at the final follow-up. No complication was observed. All patients retained full range of pronation.
CONCLUSIONS
This study provides a modified supination function reconstruction with simple operating, fine results, low risks, and no affecting of pronation function. The use of allogeneic tendon makes up for the muscles with insufficient length, making it valuable to reconsider those rebuilding operations that were once considered unpromising by many.
背景
许多方法已被提出用于治疗前臂旋前。与其他旋前功能重建相比，由于旋前能力不足，认为旋前圆肌转位术效果不理想。本研究旨在介绍一种改良方法，并与两种既往方法比较。
患者和方法
2015 年至 2020 年，11 例患者通过将同种异体肌腱缝合的旋前圆肌编织物重新布线来恢复前臂旋前。平均随访时间为 17.5 个月（12 至 24 个月）。记录末次随访时主动旋后范围。
结果
几乎所有患者均获得良好的旋前范围。末次随访时平均主动术后旋后 72.7°（60°至 80°）。未观察到并发症。所有患者均保留完全的旋前范围。
结论
本研究提供了一种改良的旋后功能重建方法，操作简单，效果良好，风险低，不影响旋前功能。同种异体肌腱的使用弥补了肌肉长度不足的问题，对于重新考虑那些曾经被认为效果不佳的重建手术具有重要意义。
