A congenital anomalous band between the flexor pollicis longus and extensor pollicis longus tendons is, according to the literature, a rare condition. This anomalous junctura was recognized in three children with congenital thumb hypoplasia. Improved thumb function was noted after surgical release of the band in all cases. In the assessment of a child with a hypoplastic thumb and apparent absent extrinsic muscle function, one should consider the possibility of conjoined flexor and extensor tendons.
根据文献记载，拇长屈肌腱和拇长伸肌腱之间的先天性异常束带是一种罕见病症。在三名患有先天性拇指发育不全的儿童中发现了这种异常连接。所有病例在手术松解该束带后，拇指功能均有改善。在评估患有发育不全拇指且明显缺乏外在肌功能的儿童时，应考虑屈肌腱和伸肌腱相连的可能性。
