Abstract: The bone plate (1) according to the invention is particularly suitable for treating fractures or non-unions and for osteotomies of the olecranon and the proximal ulna. The bone plate (1) has the following parts: a distal longitudinal shaft portion (2) having a number of plate holes (11); a longitudinal central axis (3); and a proximal head part (4), which is widened compared to the distal shaft part and has two holes (5; 6) with the hole axes (7, 8) arranged on opposite sides of the central axis (3), wherein the head part (4) is bent down relative to the shaft part (2). The two holes (5, 6) are suitable for receiving a polyaxial locking screw at an angle of ±15° relative to the respective hole axis (7; 8) or a non-locking standard screw, with the two hole axes (7, 8) forming an angle ?.

Abstract: The fracture fixation plate (1) is suitable for application to the proximal humerus, wherein •a) the fracture fixation plate (1) has an elongate body section (2) which has a free distal end (3) and a proximal end (4) to which there are adjoined, on each side, a right wing (5) having the center line (11) and a left wing (6) having the center line (12); •b) the body section (2) and the two wings (5, 6) are provided with a number of screw holes (7) for receiving bone-fastening elements (8), and the fracture fixation plate (1) has a bone contact face (9) and an opposite surface (10), and •c) the two wings (5, 6) have different lengths. Furthermore, •d) the two wings (5, 6) are curved, and •e) the extensions of the two curved center lines (11, 12) form an obtuse angle a.
