Abstract
A dynamic splint which braces any joint and particularly any body joint, and is capable of cyclically moving the joint through a programmable range of motion while accommodating normal joint component motion and triplant motion. In a preferred embodiment, an extendable cable with a cable sleeve mounted on one limb and a rotatable inner threaded cable threaded through a threaded mounting bracket on the other limb extends and contacts to cause flexing and extension of the joint.
Claims10
An apparatus for movably bracing a joint between two members comprising:
- (a) first attachment means for releasably attaching the apparatus to one of said members and second attachment means for releasably attaching the apparatus to the other of said members;
- (b) joint flexing and extending means attached to said first and second members to apply a force urging the flexing or extending of said joint;
- and
- (c) supination and pronation means cooperatively engaged with said flexing and extending means, for supinating and pronating one of said members, wherein said supination and pronation means includes a pulley cable looped around one of said members and engaged with a pulley attached to said flexing and extending means.
An apparatus for movably bracing a joint between two members, comprising:
- (a) first attachment means for releasably attaching the apparatus to one of said members, and second attachment means for releasably attaching the apparatus to the other of said members;
- (b) a cable sleeve with two ends, one of said ends being attached to one of said attachment means;
- (c) a cable rotatably mounted in said cable sleeve and with two ends, one of said ends being threadably attached to the other of said attachment means, said cable being substantially rigid except for a flexible portion adjacent to the joint to bend as the joint bends;
- and
- (d) motor means attached to said cable for threading the cable through said threaded attachment, whereby the distance between the two attachment means is lengthened and shortened to flex and extend the joint.
An apparatus for movably bracing a joint between two members, comprising:
- (a) first attachment means for releasably attaching the apparatus to one of said members, and second attachment means for releasably attaching the apparatus to the other of said members;
- and
- (b) slidable and pivotal connecting means for connecting said first and second attachment means, whereby the two attachment means can both pivot and slide with respect to one another.
