A first pair of opposed longitudinally extending slots is provided in the first part and a second pair of opposed longitudinally extending slots is provided in the second part. A first and second pin-holders are received within and threadably engage the internally threaded bore of the first part and the second part, respectively, and are configured to removably hold a first and second sets of one or more bone fixation pins extending through the first and second pairs of opposed longitudinally extending slots, respectively.
1. An orthopedic device for fixating bone parts using two sets of one or more bone fixation pins, the orthopedic device comprising:
a fixator body having a first part and a second part, the first and second parts being connected by a joint, the first part having an internally threaded bore extending longitudinally therethrough, the second part having a bore extending longitudinally therethrough;
a first pair of opposed longitudinally extending slots in the first part of the fixator body;
a first pin-holder received within and threadably engaging the internally threaded bore of the first part and configured to removably hold a first of the two sets of one or more bone fixation pins extending through the first pair of opposed longitudinally extending slots, the pin-holder longitudinally movable within the first part for controlling the position of the set of bone fixation pins within the first part;
a second pair of opposed longitudinally extending slots in the second part of the fixator body;
a second pin-holder received within the bore of the second part and configured to removably hold a second of the two sets of one or more bone fixation pins extending through the second pair of opposed longitudinally extending slots, the pin-holder longitudinally movable within the second part.
2. The orthopedic device of claim 1 , wherein the joint is a universal joint.
3. The orthopedic device of claim 2 , wherein the universal joint comprising a double-axle member providing two axes of rotation for the universal joint; and
a cannulated hinge-locking pin extending completely through the double-axle along one of the two axes of rotation, the cannulated hinge-locking pin providing a cannula for receiving a K-wire.
4. The orthopedic device of claim 1 , wherein the joint comprises two universal joints.
5. The orthopedic device of claim 1 , wherein the joint comprises two ball joints.
6. The orthopedic device of claim 1 , wherein the first pin-holder further comprises a driving screw rotatably attached to the pin-holder and threadably engaging the internally threaded bore of first part of the fixator body for moving the pin-holder longitudinally within the fixator body.
7. The orthopedic device of claim 1 , further comprising the two sets of one or more bone fixation pins.
