Bowler'S thumb in a baseball player: a case report.

A professional baseball player presented with a tender, painful and clinically enlarged ulnar digital nerve to the thumb which prevented him from batting. Thumb sensation was normal. At surgery, a 1.5 cm-length of the digital nerve was found to be thickened and enlarged. His condition was cured by detaching the adductor tendon and transplanting the nerve dorsal to the adductor muscle. Copyright 2013, SLACK Incorporated.
