Abstract: A blade assembly has a blade body and a blade body surround. A retractor attachment structure is attached to the blade body at the first end portion thereof extending from an exterior surface thereof. The retractor attachment structure is configured for having one of the blade body mounting structures of the retractor engaged therewith in a manner whereby the blade body is independently pivotable about and translatable along the blade body mounting structure. An alignment member protrudes from an interior surface of the blade body adjacent its first end portion. A slot extends through the blade body at its first end portion. The blade body surround and the blade body jointly form a generally cylindrical-shaped structure when the blade body is in a seated position within the slot. The cylindrical structure defines a central passage extending between the first and second end portions of blade body surround.

Abstract: Pedicle screw apparatuses each including a pedicle screw assembly and an attached pedicle screw extender are placed in a true percutaneous manner, thereby overcoming issues resulting from placing pedicle screw assemblies through a retractor. Thus, a retractor can advantageously be built off of the pedicle screw apparatuses, thereby allowing visualization of the spine anatomy directly. Furthermore, such a method for performing surgery ensures ideal placement of the retractor for additional procedures that are often required such as, for example, decompression, interbody device placement, etc.

Abstract: A blade system configured for use with a surgical retractor comprising a blade body and a blade body surround. The blade body includes a retractor attachment structure engagable with a blade body mounting structure of the surgical retractor. The retractor attachment structure is configured for allowing the blade body to be independently pivotable about and translatable along the blade body mounting structure. The blade body surround includes a slot within a sidewall thereof. The blade body surround and the blade body are jointly configured to form a generally cylindrical-shaped structure when the blade body is in a seated position within the slot.

Abstract: The present invention provides an intervertebral prosthesis generally defining a first wall, a second wall, sidewalls extending from the first wall to the second wall, and an upper surface and a lower surface. One or more passages may be included providing for an affixation element, to be inserted therethrough. The passages may each include a first portion for receiving a head or tip of an affixation element, and a second portion of a smaller diameter, where a substantial amount of the second portion of the passage located above or below a midline of the prosthesis. One or more openings may also be provided on the spinal prosthesis for coupling the prosthesis to a surgical tool, and the upper and lower surfaces of the prosthesis may include a depression or portion void of any teeth for the insertion of the prosthesis where a distraction tool is situated about the surgical site.
