Abstract:
1. A bone plate for the internal fixation of a fracture at the proximal ulna, the plate for placement at the olecranon, the plate machined from a solid bar and having a top surface and a bone contacting bottom surface, and defining a longitudinal axis, the plate comprising: a) a body portion having a distal end, a proximal end, a medial edge and a lateral edge and defining a plurality of threaded holes; b) a head portion extending proximally relative to the body portion, the head portion having a thickness and a width transverse to both of the longitudinal axis and the thickness, the width increasing as the distance increases from the body portion to define a transverse axis oriented perpendicular to the longitudinal axis and the thickness, the head portion including two threaded holes arranged on opposite sides of the longitudinal axis and along the transverse axis; c) a neck portion between the body and head portions, the neck portion narrower in transverse dimension than each of the body and head portions, the neck portion having a lower surface; d) a proximal arm smaller in width than the head portion, the proximal arm extending proximally from the head portion and including a proximal ring element attached to the head portion by a proximal bendable bridge element, such that the proximal arm is reconfigurable about the bendable bridge element in a plane containing the longitudinal axis and perpendicular to the top surface, the proximal ring element including a threaded hole; e) a medial arm extending medially from the neck portion and including a medial ring element attached to the medial edge of the neck portion by a medial bendable bridge element, the medial ring element having a thickness and the medial bendable bridge of reduced thickness relative to both the thicknesses of the neck portion and the medial ring element, the medial bridge element machined to position the entire medial ring element below the lower surface of the neck portion when the plate is oriented top surface facing up; and f) a lateral arm extending laterally from the neck portion opposite of the medial arm and including a lateral ring element attached to the lateral edge of the neck portion by a lateral bendable bridge element, the lateral ring having a thickness and the lateral bendable bridge element of reduced thickness relative to both the thickness of the neck portion and the lateral ring element, the lateral bridge element machined to position the entire lateral ring element below the lower surface of the neck portion when the plate is oriented top surface facing up,
