Abstract
Background: Lisfranc joint complex injury may be managed surgically by either an open reduction internal fixation (ORIF) or primary arthrodesis (PA). Published literature advocates PA for purely ligamentous injuries, but many surgeons in actuality refrain from performing PA. The purpose of the study is to assess surgeon practices and behavior in managing Lisfranc injuries due to the influence of peer reviewed literature with the help of the American Board of Orthopaedic Surgery (ABOS) database. Methods: Data were requested from the ABOS database of cases on Lisfranc joint injury requiring either an ORIF or PA from examination year 2004 to 2017 for both part II and maintenance of certification (MOC) examinees. Cases with ICD-9 code 838.03 only were considered as primarily ligamentous and all fracture codes classified under 825 with 838.03 were considered as fracture dislocation. The number of PA and ORIF were recorded for both types of examinees and specific type of Lisfranc joint injury (primarily ligamentous and fracture dislocation). Results: A total of 2010 cases of Lisfranc joint injuries managed surgically by 1230 board-eligible orthopaedic surgeons. Open fractures (93) and non-/malunion fractures were excluded. A total of 1016 primarily ligamentous and 474 fracture dislocation cases were performed by part II examinees. Overall, 288 primarily ligamentous and 139 fracture dislocation cases were performed by MOC examinees. A total of 27 PA were performed in the primarily ligamentous and 17 were performed on fracture dislocation cases. Conclusion: ORIF is commonly performed by newly trained and senior orthopaedic surgeons. There was no change in the number of PA performed on primarily ligamentous injuries in spite of the published literature.
