ABSTRACT
BACKGROUND:
Pilon fractures are devastating injuries with high complication rates. Osteonecrosis has been previously described after Weber C fracture-dislocations but has not been reported following fixation of pilon fractures.METHODS:
All AO/OTA 43-C pilon fractures from 2007 to 2018 were reviewed. Injury factors and demographics were recorded. Computed tomography (CT) scans of the fracture pattern were analyzed to determine risk factors for ON.RESULTS:
71 pilon fractures in 69 patients were included. Mean follow-up was 21.6 months. 18 patients demonstrated ON at a mean 7.3 months' post-injury. Regression analysis demonstrated no differences between cohorts with respect to smoking status, open injury, or diabetic status. ON was associated with small anterolateral fragment less than 2.0cm2 (OR=19.47, p=0.012), higher comminution (OR=3.00, p=0.005), use of calcium phosphate bone substitute (OR=20.72, p=0.013).CONCLUSIONS:
ON of the distal tibia was not associated with patient factors but was associated with fracture characteristics.Palavras-chave
