InternalBrace Fixation Technique for Lisfranc Injury:A Retrospective Study

Abstract

Abstract Background Lisfranc ligament is an important structure to maintain the transverse and longitudinal arch of the foot, due to the inherent fretting between the medial cuneiform bone and the base of the 2nd metatarsal bone, the current preferred fixation method remains controversial. Our study aimed to evaluate the InternalBrace fixation technique for Lisfranc injury. Methods A total of 58 patients who underwent InternalBrace fixation technique for Lisfranc injury from January 2019 to September 2022 through a retrospective study. Preoperative classification was performed according to Myerson classification system with imaging data. Postoperative follow-up was performed according to fracture healing time, visual analog scores(VAS), the American Orthopedic Foot and Ankle Society (AOFAS), Tegner scores and complications. Results All cases completed the operation successfully and obtained follow-up. The patients age ranged from 19 to 62 years (34.6 ± 9.4 years on average). The postoperative follow-up time was 12–24 months (16.9 ± 3.0 months on average). During the follow up period, no recurrence of lisfranc fracture-dislocations. The VAS, AOFAS and Tegner scores significantly improved as time went postoperatively, which proved statistically significant (P < 0.01), and the good rates of AOFAS was 91.4%. The postoperative complications were 1 case of traumatic arthritis, 1 case of incision infection and 1 case of temporary dorsal foot numbness. Conclusions InternalBrace fixation technique for Lisfranc injury that is benifical to restore lisfranc joint stability and function, allow earlier return to activities with fewer surgical complications.
