Elbow brace with twist adjustment
An orthopedic elbow brace having a forearm strut hinged to an upper arm strut, with two cuffs that are attached and slidable to the forearm strut, and a third cuff attached to the upper arm strut. First and second rotatable spools are positioned at the strut pivot. A lace, cable or wire interconnects the forearm and/or upper arm struts to the first spool, and another lace, cable or wire interconnects the forearm and/or upper arm struts to the second spool. Rotating the first and second spools tensions the laces, cables or wires to set an angular position between the forearm and upper arm struts corresponding to range of motion (ROM) limits for the brace. Attachment straps further secure the cuffs and the brace to the wearer's arm.
1 . An orthopedic elbow brace, comprising:
an elongated forearm strut and an elongated upper arm strut;
a single strut pivot joining the elongated forearm strut and the elongated upper arm strut together;
first and second cuffs disposed on the elongated forearm strut, wherein at least one of the first and second cuffs is slidable along the elongated forearm strut;
a third cuff disposed on the elongated upper arm strut;
at least two pivoting D-rings located proximate to each other for a V-formation and disposed on the third cuff;
first and second rotatable spools disposed on a common base plate wherein the common base plate includes an integral, single-piece plane that does not include a hinge for out-of-plane bending, and the first and second rotatable spools are positioned proximate and acting on the single strut pivot to define a range of motion contained within a single plane that is parallel to the common base plate;
a first lace interconnecting at least one of the elongated forearm strut and the elongated upper arm strut to the first rotatable spool, and a second lace interconnecting at least one of the elongated forearm strut and the elongated upper arm strut to the second rotatable spool, wherein rotating the first and second rotatable spools tensions the first and second laces to set an angular position between the elongated forearm strut and the elongated upper arm strut in flexion and in extension, corresponding to the range of motion contained within the single plane, and wherein the elongated forearm strut and the elongated upper arm strut move within the range of motion contained within the single plane in use; and
a plurality of straps disposed on the at least two pivoting D-rings and on the first and second cuffs.
2 . The orthopedic elbow brace of claim 1 , wherein the first lace wraps around the first rotatable spool and interconnects with the elongated forearm strut, and the second lace wraps around the second rotatable spool and interconnects with the elongated upper arm strut.
3 . The orthopedic elbow brace of claim 1 , wherein the first lace wraps around the first rotatable spool and interconnects with the elongated forearm strut and the elongated upper arm strut, and the second lace wraps around the second rotatable spool and interconnects with the elongated forearm strut and the elongated upper arm strut.
4 . The orthopedic elbow brace of claim 1 , wherein the elongated forearm strut includes a longitudinal slot and at least one of the first and second cuffs includes a post freely slidable therein.
5 . The orthopedic elbow brace of claim 1 , wherein the orthopedic elbow brace includes a goniometer disposed proximate the strut pivot.
6 . The orthopedic elbow brace of claim 1 , wherein at least one of the first, second, and third cuffs includes an internal sleeve that rotates axially.
