Patent number: 8828064Abstract: A bone fixation apparatus may include a bone fixation plate having a fixation hole and a fastener shaft received in the fixation hole. The fastener shaft may include a first portion having an outer surface defining a first cam and a second bone-engaging portion. An annular member may be received in the fixation hole and may include an inner surface defining a second cam for cooperating with the first cam to selectively move the annular member in a radial direction between an unexpanded position permitting movement of the fastener shaft and annular member relative to the fixation hole and an expanded position restricting movement of the fastener shaft and annular member relative to the fixation hole. The annular member may be moved between the expanded position and the unexpanded position by rotation of the annular member relative to the fastener shaft following insertion of the fastener shaft into a bone.Type: GrantFiled: April 18, 2011Date of Patent: September 9, 2014Assignee: EBI, LLCInventors: Tara Ziolo, Rui Ferreira

Patent number: 7942913Abstract: A bone fixation apparatus and associate method. The bone fixation apparatus includes a plate having a fixation hole, and a modular fastener received in the fixation hole. The bone fixation fastener includes a shaft member and an expandable head member. The shaft member has a outer cam at a first end mating with a corresponding inner cam of the head member, such that upon rotation of the head member relative to the shaft member, the head member expands against an inner surface of the fixation hole to prevent back out of the shaft member relative to the bone fixation plate.Type: GrantFiled: April 8, 2004Date of Patent: May 17, 2011Assignee: EBI, LLCInventors: Tara Ziolo, Rui Ferreira
