| description | First tarsometatarsal (TMT) arthrodesis or the modified Lapidus (ML) is a common procedure utilized by foot and ankle surgeons for the management large bunion deformities, particularly in the presence of medial column instability. The purpose of the present anatomic study was to assist surgeons in preoperative planning for ML procedure utilizing the first metatarsal to second metatarsal cross-screw technique by assessing the average length of screw guidewire placed bi-cortically through the first metatarsal and second metatarsal at a location specific to the ML procedure with metatarsal to second metatarsal cross-screw technique. This was a cadaveric study utilizing 20 fresh-frozen below-the-knee specimens. After dissection, joint preparation, and stabilization, a cannulated 4.0 screw was then placed across the first and second metatarsal bases from medial to lateral starting 1 cm distal to the 1st TMT joint. Once appropriate length and orientation was achieved the guidewire was measured using a cannulated depth gage and values were then recorded on a spreadsheet and analyzed. Amongst the 20 specimens the mean guidewire length was found to be 34 mm +/- 3.2 mm. The median guidewire length was found to be 34 mm (range: 29 – 41 mm). The present anatomic study defined the mean and median lengths of a first metatarsal to second metatarsal screw utilized for medial column stabilization and spot weld arthrodesis in the ML procedure. |
