Abstract:
1. A bone plate for the internal fixation of the coronoid of the proximal ulna, consisting essentially of: a) a central ring element including a threaded screw hole for receiving a locking fastener; b) a first arm radially coupled to the central ring, the first arm having a plurality of first ring elements each defining a threaded screw hole for receiving a locking fastener, the first ring elements each having a lower surface that is concave in a medial-lateral direction oriented transverse to a longitudinal axis extending through the first arm; c) a second arm radially coupled to the central ring, the second arm including one and only one second ring element having one and only one threaded screw hole for receiving a locking fastener, the second arm further including a single paddle-like first buttress element coupled to the second ring element by a narrower bridge element on an opposite ring from the central ring, the first buttress element having no hole for receiving a bone fastener and forming bone supporting structure that can bear against the coronoid surface; d) a third arm radially coupled to the central ring, the third arm having one and only one threaded screw hole for receiving a locking fastener; and e) a fourth arm radially coupled to the central ring, the fourth arm having one and only one paddle-like 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,
