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

Helfet and colleagues collected foot and ankle outcome scores for 187 ankle fractures treated with injury-specific anatomic fixation of either a posterior malleolus fracture (n=122) or torn PITFL (n=56).

Results showed patients in the posterior malleolus fracture group were significantly older, contained more women, had a lower mean BMI and a greater rate of medial malleolar fractures vs. the PITFL group. However, researchers noted other fracture and baseline characteristics between the two groups were similar. The posterior malleolus fracture group had a median length follow-up of 16.3 months vs. 12.8 months for the PITFL group.

At the time of most recent follow-up, univariate and multivariable analyses showed no differences in foot and ankle scores for symptoms, pain, activities of daily living, sports or quality of life. – by Casey Tingle
