Abducted Little Finger in Low Ulnar Nerve PalsyFrom the Nuffield Orthopaedic Centre, Oxford.
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.
