Abstract
A device for generating passive motion of a joint while applying traction includes a proximal bracket for engaging at least one pin inserted into a bone proximal to the joint and a distal bracket for engaging at least one pin inserted into a bone distal to the joint. The device also includes a tension-hinge mechanism connecting between the proximal and distal brackets. The tension-hinge mechanism includes a hinge for permitting rotational movement of the distal bracket relative to the proximal bracket about a hinge axis. At least one of the proximal bracket and the distal bracket is implemented as a movable bracket slidingly mounted so as to be displaceable in a direction generally perpendicular to the hinge axis. The tension-hinge mechanism also includes a traction mechanism for applying roughly constant force over a predefined range of positions of the movable bracket so as to apply tension across the joint. Also provided are jigs for use during insertion of pins around joints for orthopedic devices.
