Abstract:
A rack assembly for cross-pinning a portion of a piece of tissue in a bone tunnel extending through a first bone on one side of a skeletal joint and into a second bone on the other side of said skeletal joint, said rack assembly comprising:an L-shaped member having a base portion and an arm portion extending transversely of said base portion; a cannulated sleeve for movement through the bone tunnel in said first bone and into the bone tunnel in said second bone, said cannulated sleeve having a head portion at a free end thereof for disposition in the bone tunnel in said second bone and being connectable to the base portion of the L-shaped member at an opposite end, said head defining a window therethrough oriented substantially parallel to the base portion of the L-shaped member when said cannulated sleeve is connected to said base portion thereof, and said head extending beyond said window toward said free end so as to surround said window in a plane orthogonal to said window; a trocar sleeve guide member removably connectable to said arm portion of the L-shaped member and having bores extending therethrough at an angle normal to a projection of the longitudinal axis of said cannulated sleeve; first and second trocar sleeves for movable disposition in the bores, respectively; at least one trocar for disposition in said trocar sleeves, the trocar being interconnectable with said trocar sleeve in which the trocar is disposed, said trocar sleeve and said trocar therein being movable axially toward said head portion of said cannulated sleeve and rotatable together such that said interconnected trocar and trocar sleeve are adapted for drilling into the second bone and said at least one trocar is adapted to penetrate through the window in said head of said cannulated sleeve and a portion of a piece of tissue subsequently substituted therefore; said trocar being removable from said trocar sleeves; and said trocar sleeves being adapted to receive rods slidable through the trocar sleeves and through the portion of a piece of tissue, said trocar sleeves being removable from the second bone and from the rods so as to leave the rods in the portion of a piece of tissue and the second bone; wherein said head is configured so that when said head engages an end of the bone tunnel in said second bone, said window is aligned with said at least one trocar adapted to penetrate therethrough.
