title: Paradoxical extension phenomenon of the little finger due to repetitive trauma to the palm.
abstract: We report a case of paradoxical extension phenomenon of the little finger, so called "lumbrical plus deformity" due to repetitive trauma to the ulnar side of the palm. The adhesion between the flexor digitorum profundus tendon and the lumbrical muscle was the cause of this phenomenon. The lumbrical muscle release was sufficient to solve this rare problem.
