A digital traction system is disclosed in a hand application. A common traction plate spanning the length of the fingers and breadth of the hand may be mounted in a dorsal or is a palmar position. In the palmar position, the traction plate is anchored close to the base of the fingers or metacarpophalangeal joints by a hook and loop type fabric fastener such as that sold under the trademark VELCRO connecting the traction plate to a fingerless glove worn by the patient. Tension elements fastened to the traction plate are trained over rollers at the end of the plate and connected to finger traps which grip the patient\s fingers. In the dorsal position the plate is anchored by lugs fixed to the plate and passing between the fingers and engaging the crotches between the fingers. An auxiliary traction plate allows the thumb to be treated independently of the fingers if desired.

A traction system for the digits of a human extremity, each digit having a base and a palmar side and the extremity having a plurality of crotches between the digits comprising: a longitudinally extending traction plate for laying longitudinally alongside the palmar side of at least one of the digits, the plate having a free end and, longitudinally spaced from the free end, an anchor end; means for anchoring the plate anchor end to the extremity including a glove carried by the extremity and a contoured anchor member carried by the plate anchor end said member having a curved portion for engaging the glove and remaining in fixed relation with the extremity, said anchoring being effected solely by direct engagement of the anchoring means with the extremity adjacent the base of the at least one of the digits, the plate, in use, being substantially free of the at least one of the digits and said anchoring leaving all of the digits substantially unencumbered; and at least one elongated tension member extending generally longitudinally and having an end attached to the traction plate and an opposite end, the opposite end including means for attachment to a digit so as to apply a traction force to that digit.
