STRUCTURES FOR USE IN ORTHOPAEDIC IMPLANT FIXATION AND METHODS OF INSTALLATION ONTO A BONE

摘要

An orthopaedic implant (10, 40, 50, 60,100) including a base portion (12, 1 12) and first andsecond transverse portions (14, 16, 114, 116) extendingtransversely from the base portion (12, 112) to therebydefine an inner region (18, 1 18) of the implant sized forreceipt of an end portion of a bone (B) therein Theimplant further includes at least one anchor structure (30,130) projecting from the base portion (12, 112) andsized and configured for receipt within an opening (O,O') formed m the end portion of the bone (B) Theanchor structure (30, 130) extends along a longitudinalaxis (L) and includes a proximal end (30a, 130a)attached to the base portion (12, 112) and an oppositedistal end (30b, 130b), and further includes a tapered outersurface (36, 136) that inwardly tapers in aproximal-to-distal direction along the longitudinal axis (L) In oneembodiment, an anchor structure (130) is providedwhich includes one or more grooves (140) extendinginto the tapered outer surface (136), with a flowablematerial (150) positioned about at least a portion of thetapered outer surface (136) and positioned within thegrooves (140), and with the flowable material (150)configured to cure to a hardened state
