Persistent abduction of the little finger after ulnar nerve palsy has been attributed to the unopposed action of extensor digiti minimi. Evidence is presented that the deformity can also result when re-innervation reaches abductor digiti minimi but not the palmar interossei. Operative correction of the deformity, if required, should be delayed until it is clear that no further muscle recovery is likely to occur.
尺神经麻痹后小指持续外展被认为是由于小指伸肌的无对抗作用。有证据表明，当再支配到达小指展肌而未到达骨间掌侧肌时，也会导致这种畸形。如有必要，畸形的手术矫正应推迟到明确不可能有进一步的肌肉恢复时进行。
