SYSTEMS AND METHODS FOR PEDICLE SCREW STABILIZATION OF SPINAL VERTEBRAE

摘要

Disclosed herein are embodiments of a system for stabilizing spinal vertebrae through a skin incision, that include a first extension (410) removably coupled with a first screw (402) at a distal end thereof, and a second extension (420) removably coupled with a second screw (404) at a distal end of the second extension. A first opening (432) extends through a wall of the first extension. Further, the first opening and the wall of the first extension adjacent to the first opening is sized and configured such that the second extension can be advanced through the first opening so that the second extension is restrained within the first opening and is positionable at an acute angle relative to an axial centerline (C) of the first extension.
