Tissue graft fixation
The present disclosure relates to a graft fixation device including a body configured and arranged for passage through a bone tunnel when oriented generally longitudinally with respect to the bone tunnel, and for residing against bone defining an opening to the bone tunnel when oriented generally transversely with respect to the bone tunnel. The body defines an enclosed channel for receiving a member such that the member is substantially evenly distributed about a longitudinal extent of the body so that the body maintains a generally longitudinal orientation during passage through the tunnel, and includes a cross bar about which the member is looped when the body resides against the bone defining the opening to the bone tunnel.
1. A graft fixation device, comprising:
a one-piece body configured and arranged for passage through a bone tunnel when oriented generally longitudinally with respect to the hone tunnel, and for residing against bone defining an opening to the bone tunnel when oriented generally transversely with respect to the bone tunnel,
the body consisting of a leading end portion consisting of a pair of rectangular arms with chamfered edges joined by a curved portion which collectively define a singular oval-shaped, closed-end, tissue graft opening, the curved portion defining a single suture hole, the tissue graft opening configured for housing a portion of a tissue graft such that the tissue graft is substantially evenly distributed about a longitudinal extent of the body so that the body maintains a generally longitudinal orientation during passage through the tunnel,
a trailing end portion of said body having a singular cross bar creating said singular oval shaped closed end tissue graft opening the pair of rectangular arms extending from the singular cross bar and defining an open-ended, tissue graft channel therebetween, the arms each defining one of opposing holes for receiving one or more strands of suture that are used to flip the graft fixation device after passage through a femoral tunnel such that the fixation member is positioned against a femur and centered about a femoral opening, and
the singular cross bar having rounded smooth edges tapered to a reduced thickness relative to the body providing a smooth surface for engagement, said singular cross bar comprising a maximum height that is less than a height of the body, wherein the height of the body has a dimension that is less than the width and length of the body.
2. The graft fixation device of claim 1 wherein the trailing end portion defines a hole.
3. The graft fixation device of claim 1 , wherein the first closed-end, tissue graft opening comprises one of an oval, elliptical, or rectangular shape.
