Treatment of Distal Tibiofibular Syndesmosis Injury Associated with Ankle Fractures with Suture Button

Abstract

Objective To evaluate the results obtained from the surgical treatment of malleolar ankle fractures associated with distal tibiofibular syndesmosis (DTFS) injury submitted to conventional surgical procedure for fracture fixation and DTFS fixation by suture button (SB).

Methods Forty-nine patients were retrospectively evaluated, with a mean age of 45 years old and a mean follow-up of 34.1 months. Clinical and functional evaluation was based on the visual analogue scale (VAS) and on the American Foot and Ankle Society Score (AOFAS) for ankle and hindfoot, return to routine activities, and return to sport.

Results The postoperative mean AOFAS and VAS were, respectively, 97.06 (confidence interval [CI 95%: 95.31–98.81] and 0.16 [CI 95% 0,04 – 0,29]. All patients returned to previous daily activities, and only 12 showed some residual symptom. There was no postoperative instability in any patient. Forty-six patients returned to sports activities and, of these, only 1 did not return to the level prior to the injury. Only two patients presented SB-related alterations. There was no report of dissatisfaction.

Conclusion In malleolar fractures of the ankle with DTFS injury, the fixation of syndesmosis with SB demonstrated excellent postoperative results.

Level of Evidence IV, retrospective case series.
