Abstract
A coring reamer and method for creating a tibial tunnel and producing a bone graft for arthroscopic anterior cruciate ligament reconstruction. A conventional guide pin is drilled through the tibia and removed. A collared guide pin is then inserted through the guide pin tunnel until the collar abuts against the tibia. A cannulated core saw is slid over the guide pin and collar to engage the tibia. The tibial tunnel is reamed by driving the core saw into the tibia.
Claims10
A method for creating a tibial tunnel and producing a bone graft for arthroscopic anterior cruciate ligament reconstruction, comprising the steps of:
- drilling a guide tunnel through the tibia;
- inserting a guide pin through the guide tunnel, said guide pin having opposed ends and a collar spaced from one of the ends, until the collar abuts against the tibia;
- sliding a cannulated core saw over said guide pin and collar to engage the tibia;
- and
- reaming the tibial tunnel by driving the core saw into the tibia.
The method of claim 7, further comprising the step of saving the bone material removed from the core saw and sawing the bone material into two separate halves.
The method of claim 10, wherein an interference screw is used to fix the bone material half within the tibial tunnel.
