We report an anomalous insertion of the flexor digitorum superficialis (FDS) tendon causing multiple digit camptodactyly. The abnormal tendon was present in the ring and middle fingers, passing from the FDS tendon (proximal to the proximal interphalangeal-PIP-joint) to the extensor expansion (distal to the PIP joint). It was present on the ulnar aspect only, with no corresponding structure on the radial side. Division of the anomalous insertion corrected the fixed flexion deformity at the PIP joint. This anomaly has not been reported in clinical or cadaveric studies and could have been overlooked if a volar approach had been used.
我们报告一例指浅屈肌腱（FDS）异常插入导致多个手指屈肌腱挛缩。异常的肌腱存在于环指和中指，从 FDS 肌腱（近侧指间关节-PIP 关节近端）到伸肌扩张部（PIP 关节远端）。它仅存在于尺侧，没有相应的桡侧结构。异常插入的切断纠正了 PIP 关节的固定屈曲畸形。这种异常在临床或尸体研究中均未见报道，如果采用掌侧入路，可能会被忽略。
