| abstract |
A graft fixation device such as for use in holes drilled into the intercondylar notch of the femur for a bone-patella tendon-bone constructs, for immediate and secure fixation of both ends of a graft. The device comprises a wedge shaped shim constructed of a hard (preferably metal) biologically inert material, which is wedged in between the graft and the formed tunnel in which the graft is positioned. One side of the shim is arcuate and adapted to be from one third to one half a complete circle circumference (adapted to fit into holes of varying circumferences). The shim is either wedge shaped or formed with central aperture for insertion of an expander such as a screw, to snug up and securely wedge an adjacent graft within a bone hole. The shim does not entail bone damage such as occurs with screw fixation devices, and can be adjusted to the correct and secure holding pressure. The shim is also removable and/or replaceable for different sizes as required. |
