Abstract
A retro guidewire reamer includes a cutting member, and a mechanism for moving the cutting member from a closed position to a deployed position in a single manual motion. Once a desired size of a bone tunnel is established, a surgeon uses the reamer to create a primary bone tunnel over a guidewire from the outside in. The surgeon retracts the guidewire, and activates the mechanism to deploy the cutting member within the bone joint to conform to the size of a tendon graft. The surgeon uses the deployed cutting member to create a counter bore through the bone in a retrograde manner. Once the counter bore is drilled, the surgeon activates the mechanism to close the cutting member, allowing the reamer to be withdrawn through the primary tunnel. The retro guidewire reamer can be used to provide more accurate bone tunnel placement during ligament reconstruction surgery.
