Adult patients (&gt;\u00a018\u00a0years) with unilateral SER ankle fractures, a minimum follow-up of 1\u00a0year, no persistent symptoms, and fixation using a 1\/3 tubular 3.5-mm locking plate (lateral or posterolateral) were included. Exclusion criteria comprised bilateral injuries, Weber A\/C fractures, pathological fractures, previous ankle disorders, infection, postoperative pain, or functional limitations. The primary outcomes were peroneal tendon thickness on ultrasonography and functional performance assessed using the AOFAS Ankle-Hindfoot Scale.

In most cases (71.1%), tendon thickness was greater on the operated side. Posterolateral plating demonstrated a higher frequency of positive tendon-thickness differences. Most differences measured 0\u20132\u00a0mm (56.6%), with a statistically significant difference between lateral and posterolateral fixation groups (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
