Correction of hypermobile claw fingers in leprosy by pulley insertion procedure.

Hypermobile fingers with clawing in 14 hands were operated on from 1981 to 1985. A new muscle-tendon unit was provided to flex the metacarpophalangeal joint. The insertion was into the flexor sheath; the tendon slip was brought out through the A pulley, folded back and sutured to itself. At followup examinations, the span of the hand and grip strength were found to be increased. Integrated forger movements occurred and a good cosmetic and functional result were achieved.
