| Popis: | Category: Midfoot/Forefoot; Trauma Introduction/Purpose: Lisfranc injuries are among the most debilitating injuries to the midfoot. Various classification systems have characterized the injury patterns with specific focus on the interval between the base of the second metatarsal and the medial cuneiform as well as the importance of the ligamentous structures of the midfoot. The medial ligamentous restraints of the first tarsometatarsal (TMT) joint and the bony involvement of these injuries remains unclear. Improved knowledge on how the first TMT joint is affected in Lisfranc injuries will provide information on how best to manage these injuries. Methods: We conducted a single institution review of all Lisfranc fractures from 2010 through 2020. Patients were identified by CPT codes. Hardcastle and Myerson Lisfranc injury classifications and computed tomography and radiograph characterizations of the first TMT joint were identified by three foot and ankle trained orthopaedic surgeons. Light's kappa statistics (mean weighted Cohen's kappa) evaluated inter-rater reliability of Lisfranc classifications. The effects injury mechanism and Lisfranc classification on the first TMT joint were further assessed using t-test, Mann-Whitney U, Fisher's exact test, and analysis of variance. Results: Of 71 patients with a Lisfranc injury, 62 (87%) had a sign of injury to the first TMT joint, which significantly varied by Lisfranc classification (P |
