Abstract
A dynamic splint has a bi-directional torsional power unit fastened between first and second struts to selectively deliver force opposing either extension or flexion. The power unit is mounted about a hinge pin and can be rotated between two positions. In the first position, the power unit is locked relative to the first strut and the torsion spring opposes relative movement of the second strut in a first direction. In the second position, the power unit is locked relative to the second strut. In this second position, the torsion spring opposes movement of the first strut relative to the second strut, providing torsion in an opposite direction from that of the first position. Self-aligning contour plates on the struts conform to the anatomy and provide a mechanical interlock to bony prominences on the patient's limbs. A universal integral soft cuff/strap design simplifies set-up and provides infinite adjustment capability for increased comfort and performance. Infinitely adjustable telescoping struts facilitate custom fitting adjustment. A cam locking mechanism selectively disables the torsional force of the power unit and locks the splint in a desired position.
