Abstract

Background. Injury to the Lisfranc interosseous ligament is currently managed with a screw. However, this can potentially further disrupt the ligament. The objective of this study was to observe the proximity of the screw or disruption it can cause at the ligament attachment sites. Methods. Twenty-three feet were studied. A 40-mm, 4.0, partially threaded, cannulated screw was inserted from the base of the second metatarsal into the medial cuneiform. The relationship of the ligament attachment sites to the screw hole were measured. Results. The screw hole contacted at least 1 of the ligament attachment sites in 20 of the 23 feet. The screw hole fully penetrated it in 7 feet, partially disrupted it in 4 feet, and had less than or equal to 1 mm of contact in 9 feet. There was no contact with either of the attachment sites in 3 feet, with an average distance of 1.5 mm separating them. Conclusion. Our results show the proximity of the ligament to the screw and the disruption that can result from its insertion. This is clinically relevant as some amount ligamentous disruption is likely to occur with insertion of the “Lisfranc screw,” which may interfere with its healing process.
