    Abstract: The invention relates to a small fragment humeral head plate which is used to fix, in a stable manner, bone fracture fragments to the humeral head and shaft which is near to the body, including an elongate plate part which is sheet-shaped, in addition to an anatomically shaped head part which is attached thereto and bores which are arranged in the plate part and in the head part, said bores having a conical-shaped thread which is used to receive bone screws which comprise, respectively, a screw head with a complementary conical thread, such that an angle-stable position is produced when screwing. According to the invention, a symmetrically distributed group of bores are embodied in the head part, wherein the axis of symmetry coincides with the longitudinal axis of the plate. The first, external bores on the head part are oriented in relation to each other at an angle of between, approximately 12 degrees-17 degrees, preferably 15 degrees.
