Abstract
A surgical screw driver for inserting bone screws in bone tunnels in ligament reconstruction has, in a preferred embodiment, a rotatable operating shaft disposed at an angle to a drive shaft. A mechanism is on the drive shaft for retaining a bone screw. Methods of arthroscopic cruciate ligament reconstruction include the steps of introducing a surgical screw driver through a portal that is offset from the longitudinal axis of a bone tunnel and driving a bone screw mounted on the driver in the bone tunnel to fixate a bone block in the bone tunnel.
Claims22
A method for arthroscopic ligament reconstruction in a joint of the body:
- (a) forming in a bone of the joint a bone tunnel having a central longitudinal axis;
- (b) positioning a ligament having a terminus at each end so that a first terminus is disposed in the tunnel;
- (c) introducing a surgical screw driver from a portal that is substantially offset from the central longitudinal axis;
- (d) inserting an interference bone fixation screw in the bone tunnel with the surgical screw driver and driving the interference bone fixation screw to fixate the first terminus within the bone tunnel;
- and
- (e) fixating the second terminus to another bone of the joint.
