Abstract: A retractor system and related methods for use in spinal surgery procedures, including but not limited to fusing or repairing damaged or deteriorated intervertebral discs or vertebral bodies in the lower lumbar levels. The retractor system includes a plurality of blade assemblies coupled to a handle assembly, wherein each of the blade assemblies may be independently adjusted (e.g. length blade and/or blade angulation and/or blade rotation relative to the handle assembly) to provide unprecedented customization of an operative corridor extending to the surgical target site of the patient such that any number of spinal surgery procedures may be undertaken by a surgeon, including but not limited to spinal fusion procedures at the L5-S1 disc space.

Abstract: A generally rectangular backing member is formed of a leather material and provided with a square, leather cover member, which is emplaced over the backing member and sewn thereto to overlie a portion thereof. Three sides of the cover member lie coextensively with three corresponding sides of the backing member and the fourth side of the cover member extends across the surface of the backing member between the side edges along an angular path with one side being substantially longer than the other side. The cover member is stitched to the backing member around the edges thereof, and includes a plurality of spaced or parallel stitch lines which connect the two members in such a way as to form a plurality of separate pockets therein. The backing member folds over and snaps closed to provide a sturdy, long-lasting case for hexagonal bar-type wrenches of differing size.
