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.
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
