The invention relates to an orthopedic hinge system, including an outer and an inner later base, each substantially complemental in peripheral dimension to each other, the bases each having a major vertical axis, the inner base having a recess. Also included is an elongate distal member having a semi-circular pivot end including, upon a portion of the end, ratchet teeth pointing in a counter-clockwise direction, the pivot end rotationally secured to both of the bases. Further included is an elongate proximal member having a transverse end element proportioned for complemental securement within the recess of the inner base, transverse end element including an axis of rotation co-linear with an axis of rotation of the distal member and defining an axis of rotation of the pivot end of the distal member. The system also includes a cam lever including a pawl surface having teeth pointing in a clockwise direction and, upon contact with the ratchet teeth of the distal member, then complemental therewith, the lever having an axis of rotation co-linear with a second axis within a transverse element of the proximal member, the lever also including a radial projection disposed radially oppositely from the pawl surface to which an end of a biasing spring is attached.
