Results published in The Journal of Orthopaedic Trauma showed, when treated in an injury-specific manner, stage 4 rotational ankle fractures with posterior malleolus fractures had similar outcomes to ligamentous-equivalent injuries.

“There was no significant difference in functional outcomes of patients who had supination/pronation external rotation 4 ankle injuries with posterior malleolar fractures vs. [posterior inferior tibiofibular ligament] PITFL injuries as long as each was treated operatively in an injury-specific manner,” David L. Helfet, MD, orthopedic trauma surgeon at Hospital for Special Surgery, told Healio.com/Orthopedics.
