ABSTRACT:
A surgical screwdriver for inserting bone screws in bone tunnels in ligament reconstruction has, in a preferred embodiment, a flexible cannulated operating shaft. The shaft is formed by concentric coils including at least one clockwise helical coil and at least one counterclockwise helical coil. The screwdriver is used in methods of arthroscopic cruciate ligament reconstruction including the steps of introducing the screwdriver along a guide wire through a portal that is offset from the longitudinal axis of a bone tunnel and driving an interference screw mounted on the driver in the bone tunnel to fixate a bone block in the bone tunnel.
