Dynamic elbow support

1. A dynamic joint support, comprising:
- proximal and distal external support sections, one for each skeletal element on opposite sides of a joint;
connecting means for ridgedly connecting each support section to a bone on its respective side of the joint, wherein said connecting means attaches to the bone at a distance from the joint and not at the axis of rotation of the joint;
hinge means for connecting the support sections to each other in the vicinity of a joint so the hinge means will pivot the joint when skeletal elements move through flexion and extension; and
distraction means connected between the distal external support section and hinge for selectively moving the distal external support relative to the hinge, to distract the joint along a line oriented at an acute angle relative to a line generally perpendicular to a bone to which the distal external support section is connected.

Abstract
A dynamic joint support having proximal and distal support sections and means for rigidly connecting each support section to bone and a pair of hinges connecting each support section to each other and pivoting at the joint to cause movement of the support section and its corresponding attached bone through the movements of flexion and extension. The hinge may be driven in its movement by a gear mechanism which may be disengaged by means of a clutch. The dynamic joint support may also include a distraction mechanism for movement of the bones out of contact in the joint, while allowing for an active range of motion at the joint.
