1. A method for fixing a bone block in a bone tunnel in a bone, said method comprising the steps of:
- placing a solid bone block in the bone tunnel;
advancing at least one trocar and trocar sleeve assembly into the bone transversely of the bone tunnel such that a distal end of said at least one trocar and trocar sleeve assembly resides in said bone proximate the a sidewall of said bone tunnel, the trocar in said at least one assembly being disposed within and substantially filling its associated trocar sleeve;
removing said trocar from said at least one trocar and trocar sleeve assembly and inserting a rod into said at least one sleeve;
slidably inserting one end of an elongate shaft into said sleeve so as to abut said rod;
tapping the other end of said elongate shaft so as to drive said rod out of said sleeve, through said bone and into said bone block.

Abstract
A method for fixing a bone block in a bone tunnel comprising the steps of placing the bone block in the bone tunnel, advancing spaced-apart first and second metal wires through the bone, transversely of the bone tunnel, so as to intersect the bone block and extend through the bone block, removing one of the wires and replacing the one removed wire with a first absorbable rod, and removing the other of the wires and replacing the other removed wire with a second absorbable rod, whereby to retain the bone block in the bone tunnel with the absorbable rods.

9. A method for fixing a bone block in a bone tunnel in a bone, said method comprising the steps of:
-
forming a bone tunnel in the bone, said bone tunnel comprising an open end, a portion adjacent said open end having a transverse diameter sized to receive the bone block and an at least partially closed end located internally of the bone;
locating the bone block in said bone tunnel such that one end thereof is disposed substantially adjacent to the at least partially closed end of said bone tunnel;
advancing a drill means through the bone transversely of the bone tunnel such that the drill means intersects and extends through the bone tunnel and back into the bone substantially adjacent the other end of the bone block; and
removing the drill means from the bone and replacing the drill means with a rod;
whereby to retain the bone block in said bone tunnel between said at least partially closed end and said rod. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method for fixing a bone block in a bone tunnel, said method comprising the steps of:
-
providing a rack assembly including an L-shaped member having a base portion and an arm portion extending transversely of said base portion, a cannulated sleeve at one end thereof releasably connectable to said base portion of said L-shaped member and, at the other end thereof, adapted for disposition in said bone tunnel to align said rack assembly relative to the intended fixation location of said bone block, a trocar sleeve guide member removably connectable to said arm portion of said L-shaped member such that bores extending therethrough are disposed at an angle transverse to the intended fixation location of said bone block in the bone tunnel, first and second trocar sleeves for movable disposition in said bores, respectively, at least one trocar for movable disposition in said trocar sleeves, said at least one trocar being interconnectable with the trocar sleeve in which it is disposed, each said trocar sleeve, when said at least one trocar is located therein, being movable axially toward the intended fixation location of said bone block and rotatable together with said trocar such that said interconnected trocar and trocar sleeve are adapted for drilling into the bone, said at least one trocar being respectively removable from said trocar sleeves, and rods for sliding into said trocar sleeves;
with said cannulated sleeve in its aligning position in the bone tunnel and said sleeve guide member connected to said arm, advancing said trocar and trocar sleeve assemblies into said bone but not into said bone tunnel;
removing said at least one trocar from said trocar and trocar sleeve assemblies;
removing said cannulated sleeve from said bone tunnel and said first and second sleeves from said sleeve guide;
locating a bone block in the bone tunnel in alignment with axial projections of said first and second sleeves disposed in said bone;
providing a first elongate trocar and advancing said first trocar through said first sleeves, through the bone located between the distal ends of the first sleeves and the bone tunnel, and into the bone block;
providing a second elongate trocar and advancing said second trocar though said second sleeve, through the bone between the distal end of the second sleeve and the bone tunnel, and into the bone block;
removing said second elongate trocar from said bone block, said bone and said second sleeve;
inserting a rigid rod through said second sleeve and into said bone and said bone block;
removing said first elongate trocar from said bone block, said bone and said first sleeve;
inserting another rigid rod through said first sleeve into said bone and said bone block; and
removing said first and second sleeves from said bone. - View Dependent Claims (17)
