Abstract
A dynamic splint provides a bias force with magnitude adjustable by a mechanism located at a pivotal joint. Specific embodiments include a dynamic ankle splint incorporating a correction cradle. The correction cradle applies a torsional force to the foot, thus permitting correction of inversion and eversion of the foot in conjunction with correction of dorsiflexion and plantar flexion. In another embodiment, a dynamic wrist splint attaches to the forearm and provides a novel palm interface which adjusts to apply force over a large area of the palm depending on the relative angular position of the hand. A flexion strap is provided at the back of the hand for applying flexion forces. Further aspects of the invention include visible display of the bias magnitude. The relative magnitude is indicated by numeric markings on a rotating member of the adjustment mechanism. The portion of the rotating member having the appropriate magnitude marking is visible through an aperture in the housing. Additionally, a pin lock mechanism is provided for locking the strut members to prevent relative movement thereof and to temporarily prevent the application of force by the bias unit during attachment and removal of the splint.
