Abstract

A bone plate designed specifically to accomplish fixation of an olecranon fracture and consisting of a generally L-shaped plate including a first elongated flange and a second flange at one end of the first flange disposed at generally right angles relative to the first flange. The first flange includes a plurality of longitudinally spaced apertures through which bone attaching screws may be secured and the second flange also includes a single aperture. Screws or pins may be passed through the aperture in the second short flange and the adjacent aperture in the longer flange and anchored in the proximal fragment so as to fix and position the latter relative to the plate and the remaining portion of the long flange is then secured by screws or pins to the distal ulna after the fracture is compressed.

Claims

1. A bone plate for supporting the fractured components of an olecranon fracture in fixed position and under compression, said plate comprising a generally L-shaped rigid brace including narrow elongated rigid short and long flanges disposed at generally right angles relative to each other and fixedly joined at adjacent ends, said short flange having at least one aperture formed therethrough intermediate its opposite ends and said long flange having at least three apertures formed therethrough with one of said three apertures being disposed adjacent the end of said long flange joined to said short flange, and at least four elongated bone component anchoring fasteners for passage through said apertures and anchoring in the bone components, said bone component anchoring fasteners including headed elongated fasteners having threaded shank portions, the heads of said fasteners including generally frusto-conical undersurfaces, the aperture formed through said short flange being of the keyholetype including a slot extension extending lengthwise of the short flange away from the long flange and the aperture formed through the end of the long flange remote from the short flange being also of the keyhole-type and including a slot extension extending lengthwise of the long flange away from said short flange, the portions of the apertures and said slot extensions opening outwardly of the flange surfaces defining the outside corner of the brace being chamfered.

2. The combination of claim 1 wherein said long flange includes at least one additional aperture formed therein.
