  • Dynamic mp joint extension splint
    Patent number: 4949711
    Abstract: A low-profile dynamic hand splint including a rigging which is attached to a finger sling and which uses a single extendable coil spring to generate a variable tension force in the rigging. The tension force in the rigging is adjusted over a range of up to approximately 400 grams by attachment of one end of the rigging to various points on the base of the hand splint using releasable hook and loop fasteners. Use of a single extendable coil spring with an adjustable attachment point for the end of the rigging permits the rigging to be short in length and to be conveniently attached to the splint near a patient's wrist.
