The present disclosure provides an expandable fastener for orthopaedic applications and arranged for fastening when positioned in a bore hole in bone. The fastener comprises a body having an axis. The fastener further comprises an expansion portion moveable between a contracted configuration and an expanded configuration such that, in use, the expansion portion urges outwardly from the body towards the bone surrounding the bore hole. The fastener is arranged such that ingrowth of bone between the expansion portion and the body is substantially avoided when the expansion portion is in the expanded configuration.

Expandable fastener for orthopaedic applications

The present disclosure provides a fastener that has a body that has an axis. The body comprises a head portion and at least one body portion projecting from the head portion. The at least one body portion has an actuating surface portion and is arranged such that at least a part of the at least one body portion is urged away from the axis when an actuating member is received along the axis and urges against the actuating surface portion. The at least one body portion has a substantially flat surface portion facing away from the axis.
