A dynamic splint has a bi-directional torsional dynamic tension unit (348) fastened between first and second struts (308,388) to selectively deliver force opposing either extension or flexion. The tension unit (348) is mounted about a pivot post (34) and can be rotated between two positions. In the first position, the power unit is locked relative to the first strut (308) and the torsion spring opposes relative movement of the second strut (388) in a first direction. In the second position, the tension unit (348) is locked relative to the second strut (388). In this second position, the tension unit (348) opposes movement of the first strut (308) relative to the second strut (388), providing torsion in an opposite direction from that of the first position. Self-aligning contour plates (334) on the struts conform to the anatomy and provide a mechanical interlock to bony prominence on the patient's limbs.
