Comminuted depressed fracture of lateral tibial plateau of left knee with 9.4mm depression and subchondral collapse. Fracture lines traverse to the epimetaphysis without any displacement.
Incidental bony outgrowths at distal diametaphysis of both femurs in the medial aspect as well as in the medial aspect of proximal left tibial diaphyses. These bony exostoses show preserved cortical continuity and normal transition of medullary marrow into the lesion.
Case Discussion
Tibial plateau fractures are classified based on Schatzker system.
The multiple exostoses were incidentally found and are typical of diaphyseal aclasis or hereditary multiple exostoses.
