Abstract
An internal joint distraction device provides articulation to an articulating bone joint between an upper bone structure and a lower bone structure. The device includes a medial plate shaped to at least partially conform to a medial side of a bone structure of a limb and includes a lateral plate shaped to at least partially conform to a lateral side of a bone structure of a limb. Each of the medial and lateral plates may include a longitudinal length sufficient to extend from the upper bone structure to the lower bone structure thereby spanning at least a portion of the joint. Each plates includes at least one proximal connection feature formed therein for connecting to the upper bone structure and at least one distal connection feature formed therein for connecting to the lower bone structure. An axle extends from one of the connection features on the medial plate to one of the connection features on the lateral plate. The axle extends through one of the upper and lower bone structures in a manner that said one of the upper and lower bone structures pivots about the axle relative to the other of the upper and lower bone structures.
