Procedure for repairing foot injury

摘要

A Lisfranc injury between a second metatarsal and medial cuneiform is repaired by gaining access to the injury site and placing two arm members of a novel drill guide around the two neighboring bones at the injury site, drilling a guide wire through the two bones guided by the drill guide to a desired depth, measuring the depth of the guide wire to determine the proper length for a bone screw for securing the two bones, drilling a cannulated drill bit into the two bones to a drill depth using the guide wire as a guide, and threading a bone screw into the two bones.

主权项

1. A method for repairing a Lisfranc injury between a second metatarsal and medial cuneiform comprising the steps of:
(a) providing a drill guide assembly device comprising:
an elongated body having first and second ends;a first arm member extending from said first end of the elongated body;a second arm member extending from said elongated body and configured and adapted to be longitudinally movable along said elongated body;one of the two arm members provided with a guide housing and the other of the two arm members having a generally curved tip portion; anda sleeve having a longitudinal bore, wherein said guide housing is configured and adapted to removably receive said sleeve, wherein said guide housing is provided with at least one spike extending towards the other of the two arm members whereby one or more bone pieces positioned between the first and second arm members is secured between said at least one spike and said other of the two arm member's outer end by moving the second arm member towards the first arm member; (b) making an incision to access said Lisfranc injury site; (c) placing said curved tip portion of one arm member between the second metatarsal and third metatarsal base; (d) placing said at least one spike on the medial side of the medial cuneiform in desired alignment with the curved tip portion by closing the two arm members; (e) reducing the second metatarsal and the medial cuneiform by compressing the two arm members; (f) inserting a first sleeve into the guide housing, said first sleeve configured and adapted for receiving a guide wire; (g) drilling a guide wire through the medial cuneiform and the second metatarsal in an alignment guided by the first sleeve to a desired depth which is until the guide wire hits the curved tip portion; (h) removing the first sleeve and measuring said depth of the guide wire for determining a proper length for a bone screw for securing the second metatarsal and the medial cuneiform; (i) inserting a second sleeve into the guide housing, said second sleeve configured and adapted for receiving a cannulated drill bit; (j) drilling a hole through the medial cuneiform and the second metatarsal using the guide wire as a guide; (k) securing the medial cuneiform to the second metatarsal by threading a bone screw into said drilled hole; and (l) removing the drill guide assembly device.
