Background:
This study investigated radiological changes in syndesmotic injuries after suture-button fixation, from the immediate postoperative period to the resumption of daily activities.
Methods:
We retrospectively analyzed 38 patients who underwent syndesmosis fixation using a suture-button. Anterior difference (AD), posterior difference (PD), fibular translation (FT), and fibular rotation (FR) were measured on computed tomography scans and compared across time points and with the contralateral side.
Results:
AD and PD significantly increased preoperatively, decreased immediately postoperatively, and were slightly increased or maintained at 6 months, resembling the normal side. FT showed no significant changes over time. FR decreased immediately after surgery and slightly increased at 6 months, approaching values of the contralateral side.
Conclusions:
Suture-button fixation initially over-narrowed the syndesmosis compared to the normal side. However, with weightbearing and daily activities, the overcorrected syndesmosis gradually adjusted to resemble the uninjured side.
Level Of Evidence:
III.
