User Review
5 (1 vote)

Opponents splint is primarily functioned to hold the thumb in a position opposing the index and middle fingers. It is a custom fit or molded brace used to support weak muscles and/or immobilize or limit the motion of joints. It may be made of thermoplastic, canvas, metal, or a combination of materials. This position is more functionally suitable. Its dorsal and palmar bars support the metacarpal arch and prevent it from flattening.
