Abstract:
1. An external fixation device for facilitating the healing and repair of bone fractures of the hand, wrist and lower arm, the device comprising: (a) a distal member comprising a dorsal pivotal engagement hub and defining a mounting aperture, (b) a pivot member comprising a first pivotal engagement hub and a second pivotal engagement hub, wherein the rotational axes of said first and second hubs are generally orthogonal, (c) a distraction member comprising a lateral pivotal engagement hub, and (d) a radial member defining a mounting aperture, wherein said dorsal pivotal engagement hub of said distal member is connected to said first pivotal engagement hub, forming a revolute joint, to define lateral flexion of the hand with respect to the lower arm, said lateral pivotal engagement hub of said distraction member is connected to said pivot member at said second pivotal engagement hub, forming a revolute joint to allow said distraction member to rotate with respect to said pivot member, to define palmer-dorsal flexion of the hand with respect to the lower arm, and said radial member translationally connected to said distraction member; and wherein said distal member and said radial member further define a well coaxial with said mounting aperture.
