Abstract
To the Editor: An occupational paralysis of the muscles supplied by the deep palmar branch of the ulnar nerve was first described in 1896 under the title "A Peculiar Form of Progressive Muscular Atrophy in Gold Polishers."1 The neuropathic origin was recognized by Hunt in 1908 when he reported distal ulnar neuropathy after prolonged oyster opening.2 Cases have also followed shoveling with a spade,1 , 3 carpentry, and use of vibrating buffers, wire cutters, leather-cutting knives, floor polishers, and pneumatic drills. Other causes include laceration, carpal-bone or radius fracture, scar-tissue contracture, ulnar-artery disease, anomalous muscles, osteoarthritis, ulnar-nerve tumor, lipoma, and hemorrhage.1 , 3 , 4 Distal . . .
