ABSTRACT:
An instrument is provided for use in orthopedic surgery, such as for reduction of spinal rods. In one embodiment, a shaft is pivotably connected to a plate with an aperture, and a sleeve is slidable over the shaft and plate. A base member can be provided for ease in handling the instrument, which may include a ratchet mechanism connected to the sleeve. The plate is moved so that its aperture is oriented to allow an orthopedic implant, such as a Schanz-type screw, to be inserted into the aperture. After insertion, the shaft is moved so as to pivot the plate so that the plate grips or holds the implant. The sleeve is then slid over the shaft, plate and implant in contact with an elongated member, such as a spinal rod, or other implanted device or tissue. Further sliding the sleeve forces the elongated member toward or past the implant.
