Abstract

See full text

An implant with an interference fit fastener for attaching the implant to a bone. The interference fit prevents backout of the fastener after the attachment. The implant may include a passage with a first end and second end. The passage may include a first interference section between the first and second ends. A fastener with an elongated shape may be sized to extend through the passage to attach the implant to the bone. The fastener may include a second interference section. During insertion of the fastener through the passage and into the bone, the second interference section of the fastener may contact against and modify or be modified by the first interference section of the passage. This modification may create the interference fit between the implant and the fastener that prevents backout. The interference sections may remain in contact or may move apart once the fastener is fully attached to the bone.
