Abstract
A surgical screwdriver for inserting bone screws in bone tunnels in ligament reconstruction has, in a preferred embodiment, a cannulated flexible shaft portion. The flexible shaft portion is formed by a plurality of linkage members disposed in series. Each linkage member is joined to an adjacent linkage member so as to permit adjacent linkage members to be pivotally movable with respect to one another about a pivot axis. 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.
