Drill guides and inserters for bone plates having hook members

a technology of bone plate and inserter, which is applied in the field of fixing bone fractures, can solve the problems of inability to place screws through both cortices, inability to drill through the cortices, and inability to provide adequate space for more than one or two screws to be placed, so as to facilitate the drilling of at least, facilitate the drilling of locking pegs, and enhance the effect of subchondral fixation

Abstract

A system for assisting a surgeon in implanting hook plate-type bone plates includes a cannulated multiple barreled drill guide, a cannulated inserter / impactor, and a cannulated fastener coupling the inserter / impactor to a bone plate. The multiple barreled drill guide facilitates the drilling of at least two parallel holes at the distal end of a bone at the correct position and angle of entry, and includes a body and two drill guide channels coupled to the body in substantially parallel orientation relative to each other, with a guide pin aperture disposed between and substantially parallel to the drill guide tubes. The inserter / impactor likewise includes a central channel accommodating the same guide pin employed to place and align the multiple barreled drill guide.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. provisional patent application No. 61 / 901,964, filed Nov. 8, 2013, the entirety of which is hereby incorporated by reference.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates, in general, to the fixation of bone fractures and, more particularly, to the fixation of bone fractures having small fragments proximate a terminal end of a bone.

[0004] 2. Description of Related Art

[0005] Plates and screws are well accepted techniques for fixation of fractures. The standard bone plate is a planar bar of material, usually metal, having circular and / or slotted holes through which bone screws are placed. The bone plate is used to span a fracture and fixation screws are placed through holes in the bone plate positioned on either side of the fracture to secure the bone fragments the plate.

[0006] One example of a fracture occurring relatively close to the end of a bone is...
