The aims of this study were to identify the location of the A1 pulley combining palpation technique with superficial palm landmarks and to determine the efficacy and safety of A1 pulley percutaneous release with a 19-gauge needle. Fourteen fresh frozen cadaveric specimens were used: 56 fingers and 14 thumbs. The location of the A1 pulley was based on anatomical landmarks and was identified in all digits. Complete release of the A1 pulley occurred in 60 of the 70 digits (85.7%). The length of the A1 pulley in thumbs was 5.7 mm and in other fingers 4.5 mm. There were no signs of neurovascular bundle injuries. The mean distance between needle pathway and neurovascular bundle was 4.3 mm in the thumbs and 6.5 mm in the other fingers. There were no total flexor tendon injuries. The location of the A1 pulley can be predicted with success. Percutaneous release of the A1 pulley with a 19-gauge needle shows acceptable results in both safety and efficacy.
本研究的目的是结合触诊技术与手掌浅表标志来确定A1滑车的位置，并确定使用19号针进行A1滑车经皮松解术的有效性和安全性。使用了14个新鲜冷冻尸体标本：56根手指和14根拇指。A1滑车的位置基于解剖标志，在所有手指中均被确定。70个手指中有60个（85.7%）实现了A1滑车的完全松解。拇指的A1滑车长度为5.7毫米，其他手指为4.5毫米。没有神经血管束损伤的迹象。拇指针道与神经血管束之间的平均距离为4.3毫米，其他手指为6.5毫米。没有发生完全的屈肌腱损伤。A1滑车的位置可以成功预测。使用19号针进行A1滑车经皮松解术在安全性和有效性方面均显示出可接受的结果。
