Fixing plate with distal radius fracture facet support ulnar volar integrated and adjustable

摘要

A bone plate (10) for a palmar side of a distal end of the radius bone for use with a Kirschner wire 1.6 mm, the bone of the distal radius that has a shaft and a metaphysis and metaphysis having an edge palmar, comprising: a) a lower contact surface with the bone (16); b) an opposite upper surface (18); c) a shaft (12) including a plurality of mounting holes (20, 22, 24) for securing said shaft (12) relative to the radius bone; d) a head (14) extending in a transverse orientation relative to said axis (12), said head (14) angled upwardly relative to said axis (12) when said bottom surface (16) of said shaft (12) is positioned substantially horizontal and facing downward, said head (14) including a plurality of threaded holes (28), each defining a threaded shaft along which a fastener inserted into threaded holes retains along said threaded shaft, said head (14) including a radial side (40) and an ulnar side (42), said radial side (40) that tapers to a distal edge (54) and free any tongue, said ulnar side (42) provided with first and second spaced tabs (44, 46) extending distally beyond said radial lateral distal edge (54), each of said tab (44, 46) provided with a hole for the K-wire (56, 58) with side walls cilin Doric able to closely receive the Kirschner wire 1.6 mm and retain the K-wire at a fixed angle, the upper surface of each of said tabs (44, 46) having a smooth contour with a distal edge tapered, a recess (50, 52) of each respective tongue (44, 46) provided to the bottom surface (62) of said bone plate and extending along an entire bond between each of said tabs (44, 46) and a remainder of said head (14) in alignment with said radial lateral distal edge (54) to reduce a moment of the cross-section of inertia in them so that when the Kirschner wire is inserted in said hole for wire Kirschner (56, 58) and a bending load the Kirschner wire, said plate (10) is applied bends in said area of ​​reduced cross section to reorient each of said tabs (44, 46) about an axis in alignment with said edge far l radial side.
