We report a rare case of limitation of active flexion and subcutaneous bow-stringing as a result of flexor pulley rupture after repeated corticosteroid injections for trigger thumb. Complete rupture of the A1 and oblique flexor pulleys was confirmed during surgery, and the pulley system was reconstructed with a "three-loop technique" using a free palmaris longus autograft. This technique provided enough strength to allow early mobilization and prompt recovery to full range of motion.
我们报告了一例罕见病例，该病例因反复注射皮质类固醇治疗扳机指后屈肌滑车破裂，导致主动屈曲受限和皮下弓弦征。手术中证实A1和斜屈肌滑车完全断裂，采用游离掌长肌自体移植的“三环技术”重建滑车系统。该技术提供了足够的强度，以允许早期活动并迅速恢复到全范围运动。
