Abstract
Abstract A graft attachment device having an elongated body with a leading end and a trailing end, each defining an element for carrying a filament such as a suture. The body further defines at least one element for attaching to the body either a graft or a graft connection element which is in turn connected to the graft. The element for attaching enables the body to rotate relative to the graft from an initial insertion position, along an axis substantially parallel to the graft, to a final fixation position transverse to the graft to secure the graft relative to a bone. A method of attaching a graft to the bone using such a graft attachment device includes forming a socket in a bone such as a femur to accommodate an end of the graft, the socket having an opening at one end and a floor at its opposite end. A passage is formed from the floor of the socket to the opposite side of the bone, the passage having a width at least as large as the maximum width of the graft attachment device. The graft is secured to the element for attaching, and the lead and trailing filaments are inserted through the passage. The lead filament is pulled until the elongated body of the graft attachment device emerges from the passage. the elongated body is then rotated by pulling on the trailing filament to rotate the body from the initial insertion position to the final fixation position transverse to the graft. The elongated body is then seated against the surface of the bone by pulling on the graft to fixate the graft to the bone.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
200 words
A method of attaching a graft to bone, comprising: forming a first socket in a bone to accommodate a portion of the graft, the socket having an opening at one end and a floor at its opposite end; providing a first graft attachment device having an elongated body with a maximum length, a maximum width, an upper surface, a lower surface, a leading end, and a trailing end, each end carrying a first lead filament and a first trailing filament, respectively, the body further defining means for attaching to the body one of the graft and a graft connection element; forming a first passage from the floor of the socket to the opposite side of the bone, the passage having a width at least as large as the maximum width of the graft attachment device; securing the graft to the means for attaching; inserting the first lead and trailing filaments through the first passage and pulling primarily on the lead filament until the elongated body of the graft attachment device emerges; and rotating the elongated body by pulling on the trailing filament and seating the elongated body against the surface of the bone to fixate the graft to the bone.
Claim 2
Independent Claim
200 words
A method of attaching a graft to bone, comprising: forming a first socket in a bone to accommodate a portion of the graft, the socket having an opening at one end and a floor at its opposite end; providing a first graft attachment device having an elongated body with a maximum length, a maximum width, an upper surface, a lower surface, a leading end, and a trailing end, each end carrying a first lead filament and a first trailing filament, respectively, the body further defining means for attaching to the body one of the graft and a graft connection element; forming a first passage from the floor of the socket to the opposite side of the bone, the passage having a width at least as large as the maximum width of the graft attachment device; securing the graft to the means for attaching; inserting the first lead and trailing filaments through the first passage and pulling primarily on the lead filament until the elongated body of the graft attachment device emerges; and rotating the elongated body by pulling on the trailing filament and seating the elongated body against the surface of the bone to fixate the graft to the bone.
Claim 3
Dependent Claim
34 words
The method of claim 1 wherein the socket is formed to a depth substantially equal to a desired insertion depth for the graft plus one-half of the maximum length of the graft attachment device.
Claim 4
Dependent Claim
17 words
The method of claim 1 wherein the graft is secured to the means for attaching by sutures.
Claim 5
Dependent Claim
26 words
The method of claim 1 wherein the graft to the means for attaching by being looped over a sling member connected to the means for attaching.
Claim 6
Dependent Claim
