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: (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.
