Abstract
A bone plug for intramedullary insertion into the canal of a bone to restrict the bypass of cement during implant surgery is described. The bone plug is made of a bioabsorbable material and has a tapered central body providing the primary support for the plug. A plurality of radially extending disc-like fins extend from the body at spaced locations. The taper provides the distal fin with a greater degree of flexibility due to the long cantilever, thus permitting an ease of insertion into the intramedullary canal while the larger diameter body and shorter proximal fins lend structural stiffness to resist the migration of the device.
