Elbow fracture fixation system

摘要

A bone plate for the internal fixation of the coronoid of the proximal ulna includes a central ring element including a screw hole. A first arm is radially coupled to the central ring, the first arm having a plurality of screw holes. A second arm is radially coupled to the central ring, the second arm including a second ring element having a single screw hole, and further including a single first buttress element coupled to the second ring element, the first buttress element having no hole for receiving a bone fastener and forming bone supporting structure that can bear against the coronoid surface. A third arm is radially coupled to the central ring, the third arm having a single screw hole. A fourth arm is radially coupled to the central ring, the fourth arm having a single second buttress element with no hole for receiving a bone fastener, the second buttress element forming bone supporting structure that can bear against the coronoid surface.
