Abstract
A fixation system for drawing together into engaging relationship mutually opposed fracture surfaces of a pair of bone fragments at a fracture site. An elongated blade with a sharpened leading end is driven into a first bone fragment generally parallel to and spaced from a fracture surface of the first bone fragment. A flange member integral with the blade extends transverse of the blade and overlies the fracture site between the first and second bone fragments. At least one screw fastener with a head and threaded shank extends through an opening in the flange and is threaded into the second bone fragment along an axis which extends away from the blade. With continued tightening of the screw fastener, the head engages the flange and draws the flange against both bone fragments, holds the blade in a deepest seated relationship with the first bone fragment, and imparts a compressive or wedging force to the first and second bone fragments forcing them together at the site of fracture and enabling healing to proceed.
