In the dual-plating concept for intercondylar distal humerus fractures, the medial plate carries a particular burden: it fixes the column that supports the trochlea, the half of the joint around which the forearm actually hinges. Its screws work in the bone of the medial epicondyle and the medial ridge, and the plate must follow that anatomy closely to sit without prominence.
Traditional plates keep their place in elbow trauma for good reasons. They contour easily at the table, they compress the fracture as the screws seat, and in good bone they give the surgeon tactile control that fixed-angle systems deliberately remove. Whether a case calls for a traditional or a locking medial plate, and how the medial plate pairs with the lateral construct, is the operating surgeon's call.
