Abstract:
A bone clamp for temporary securement of adjacent bone segments of an involved bone separated by a fracture following open reduction thereof, said bone clamp comprising:a pair of jaw members opposed to one another and mutually urgeable together, each of said pair of jaw members including support structure, said support structure presenting an expanded dimension extending between opposed ends thereof, said support structure being oriented crosswise to a direction in which said jaws are urgeable together for codirectional alignment of said expanded dimension with a longitudinal direction of the involved bone when same is received between said pair of jaws, the fracture being oriented proximate an intermediate position located between said opposed ends of the support structure and spaced apart therefrom;gripping structure carried on said support structure in a gripping region between each of said opposed ends and either corresponding side of said intermediate position of both of said pair of jaws for opposed contact of said gripping structure of each said gripping region with a respective one of the adjacent bone segments, said gripping structure being brought into secured engagement by continued urging together of said pair of jaws;said gripping structure including penetrating bodies at least a portion of which at least partially pierce said involved bone in response to continued urging together of said pair of jaws;said penetrating bodies including at least two spikes carried on each of said pair of jaw members, at least one of said at least two spikes being disposed on each side of said intermediate position on each of said pair of jaw members; andsaid at least two spikes are disposed one on each side of said intermediate position, each of said at least two spikes being oriented at an angle outwardly divergent from a compression axis extending through said intermediate position and which is representative of a direction of jaw movement effected by urging together of closure of said pair of jaws and codirectionally angled with respect to said expanded direction, said at least two spikes thereby being respectively angled away from the fracture in a direction along a longitudinal axis of the involved bone interposed between said pair of jaws whereby continued urging of said pair of jaws effects reduction of the fracture.
