ABSTRACT:
A device for use in setting of fractured wrist or other wrist disorders including a rigid rod member adjustable in length, a pair of holders fastened to the member and each carrying at least one transcutaneous pin which is intended to penetrate the skin and muscle so that the free ends of the pins may be secured in holes drilled in the bone parts. The pins of one holder are adapted for entering the bone distal the wrist and the pins of the other holder are adapted for entering the bone proximal the wrist. The pin adapted for entering the bone distal the fracture is operatively connected to a compound arc gear adapted to move the wrist through a predetermined path of flexion or extension. The compound arc gear has a plurality of sections each of predetermined varying radius of curvatures to correspond to the physiologic path of flexion or extension of the patient fitted with the device.
