The smooth shaft of the 4.5mm Malleolar Screw is partly threaded. Malleolar screws with a cortical thread, shaft, and trocar tip have limited usage in the metaphyseal, distal humerus, trochanteric, and possibly ankle areas where the bone is thick.
Specifications
Partially threaded threads provide the optimum fit of threads into the distant bone fragment, allowing for improved interfragmentary compression.
When the screw is inclined, the hemispherical head diameter enables excellent annular contact with washers and plates.
