Abstract:
1. A method for securing a transplant in a bone tunnel, comprising the steps of: forming a tunnel in a bone; providing a fixation device for securing a transplant in said tunnel, having a strap with a plurality of protrusions disposed along its length, a fastening member with an aperture therein for passing the strap, and a connection element disposed at a distal end of said strap for engaging a transplant, said fastening member further comprising a distal side, a longitudinal axis of said aperture being substantially parallel to a longitudinal axis of said bone tunnel when said fastening member distal side lies substantially flush against an outer surface of the bone, said fastening member further comprising a self-locking element having a camming surface adjacent to a locking surface positioned to engage at least one of said plurality of protrusions and a stem, said camming surface defining a portion of said aperture and said locking surface being parallel to the distal side of said fastening member, said stem flexibly connecting said self-locking element to said fastening member; engaging a transplant on said connection element; passing a proximal end of said strap through said tunnel; passing a proximal end of said strap through said aperture, said plurality of protrusions causing said stem to flex slightly inward and engaging said plurality of protrusions with said locking surface; and moving said fastening member in a distal direction down said strap until an undersurface of said fastening member engages the bone; wherein said camming surface is positioned at a 45-degree angle with respect to the distal side of said fastening member.
