Abstract
The objective of this study was to report early outcomes of a novel screw-suture syndesmotic device compared with suture button fixation devices when treating traumatic syndesmotic instability. Retrospective chart review. Single academic Level 1 Trauma Center. All adult patients who had syndesmotic fixation with the novel device [novel syndesmotic repair implant (NSRI) group] compared with a suture button device (SB group) between January 2018 and December 2022. Medial clear space and tibiofibular overlap measurements were compared immediately postoperatively and at the final follow-up. Patients were followed for a minimum of 1 year or skeletal healing. Fifty-nine patients (25 female) with an average age of 47 years (range 19-78 years) were in the NSRI group compared with 52 patients (20 female) with an average age of 41 years (range 18-73 years) in the SB group. There were no significant differences when comparing body mass index, diabetes, or smoking status between groups (P > 0.05). There was no difference when comparing the postoperative and final medial clear space measurements in the NSRI group compared with the SB group (P = 0.86; 95% confidence interval, -0.32 to 0.27). There was no difference when comparing the postoperative and final tibiofibular overlap measurements in the NSRI group compared with the SB group (P = 0.79; 95% confidence interval, -0.072 to 0.09). There were 3 cases of implant removal in the NSRI group compared with 2 in the SB group (P = 0.77). There was 1 failure in the NSRI group and none in the SB group. The remaining patients were all fully ambulatory at the final follow-up (P = 0.35). A novel screw-suture syndesmotic implant provides the fixation of a screw, and the flexibility of a suture had similar radiographic outcomes compared with suture button fixation devices in treating ankle syndesmotic instability. Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
