Abstract
A counter-torque wrench for use with spinal implantation systems is provided wherein the counter-torque wrench engages a spinal implant rod and a bone screw body in a manner to promote a perpendicular alignment between the longitudinal axis of the rod and the longitudinal axis of the bone screw body, and a co-linear alignment between the longitudinal axis of the bone screw body and the longitudinal axis of the wrench body. The counter-torque wrench may comprise a handle attached to a first end of the counter-torque wrench body and a rod engaging member attached to a second end of the counter-torque wrench body. The rod engaging member may comprise generally opposing slots, wherein each slot comprises a prong extending into each slot, the prong creating a generally L-shaped slot, and a pocket formed by a curved feature of each slot. The opposing slots may be sized and shaped to releasably attach to the spinal implant rod in an engaged position perpendicular to the counter-torque wrench body when the counter-torque wrench is rotated in a counter-clockwise direction.
