We present an anatomic variation of type IIIA thumb hypoplasia in which a tendinous interconnection between the flexor pollicis longus and the extensor pollicis longus occurred on the ulnar aspect of the thumb. Interconnection between extrinsic flexor and extensor systems is well known in type IIIA thumb hypoplasia and has been reported on the radial side (pollex abductus). In our patient the ulnar location of the interconnection remained unrecognized until recurrence of the deformity in adolescence.
我们展示了一例 IIIA 型拇指发育不全的解剖变异，其中拇长屈肌和拇长伸肌之间的腱性连接出现在拇指的尺侧。外在屈肌和伸肌系统之间的连接在 IIIA 型拇指发育不全中是众所周知的，并且已经有在桡侧（拇外展）的报道。在我们的患者中，这种连接的尺侧位置直到青春期畸形复发才被发现。
