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.

A method for fixing a bone block in a bone tunnel in a bone, the method comprising the steps of:
- placing the bone block in the bone tunnel;
- advancing a first drill means through a first portion of the bone and transversely of the tunnel so as to intersect and extend through the bone block;
- advancing a second drill means through a second portion of the bone and transversely of the tunnel so as to intersect and extend through the bone block, said second drill means being spaced from said first drill means;

- removing the other of the first and second drill means;
- and
- advancing a second absorbable rod through a bore left by removal of the other drill means, such that the second absorbable rod extends through the bone and the bone block;
- whereby to retain the bone block in the bone tunnel with said absorbable rods.

A method for fixing a bone block in a bone tunnel in a bone, the method comprising the steps of:
- placing the bone block in the bone tunnel;
- advancing spaced-apart first and second trocar and sleeve assemblies through the bone transversely of the bone tunnel so as to intersect the bone block and extend therethrough, the trocar in each of said assemblies being disposed within one of said sleeves of said assemblies and substantially filling said sleeve;
- removing said trocar from said first of said sleeves, advancing a first absorbable rod through said first sleeve and through said bone block, and then removing said first sleeve, so as to leave said first absorbable rod in said bone and said bone block;
- and
- removing said trocar from said second of said sleeves, advancing a second absorbable rod through said second sleeve and through said bone block, and then removing said second sleeve, so as to leave said second absorbable rod in said bone and said bone block;
- whereby to retain the bone block in the bone tunnel with said rods.
