Patent number: 9066751Abstract: Instrumentation and methods are provided for mounting a surgical navigation reference frame to a patient. A trocar may be positioned within a cannula to form an insertion device adapted for percutaneous introduction into the patient. A bone anchor having a bone engaging portion is inserted through the cannula for anchoring to bone. The bone anchor cooperates with the cannula to form a mounting device adapted for coupling with the surgical navigation reference frame. An image-guided surgical procedure may be performed at a location remote from the anchoring location. In a specific embodiment, a minimally invasive surgical procedure is performed, with a reference frame anchored to the pelvic bone, and more specifically to the iliac region of the pelvic bone. A second reference frame may be anchored to the femur.Type: GrantFiled: January 17, 2012Date of Patent: June 30, 2015Assignee: Warsaw Orthopedic, Inc.Inventor: Ricardo Sasso

Publication number: 20140200617Abstract: A posterior fixation system includes a saddle member, an anchoring member, an occipital plate, an occipital rod, and a cross-link connector. The anchoring member anchors the saddle member to bone. The saddle member includes a channel that is adapted to receive an orthopedic rod. The saddle member and the anchoring member can be coupled so as to allow multi-axial movement of the members. Connection of individual rods can be accomplished by connecting the rods with the cross-link connector. The occipital plate secures the rods to the occipital bone of the skull. Alternatively, the occipital rod can be secured to the occipital bone.Type: ApplicationFiled: August 19, 2013Publication date: July 17, 2014Applicant: WARSAW ORTHOPEDIC, INC.Inventors: Robert A. Farris, Kevin T. Foley, Stephen M. Papadopoulos, Jeffrey W. Poyner, Ricardo Sasso

Patent number: 8512380Abstract: A posterior fixation system includes a saddle member, an anchoring member, an occipital plate, an occipital rod, and a cross-link connector. The anchoring member anchors the saddle member to bone. The saddle member includes a pair of upright portions that define a channel. The channel is adapted to receive an orthopedic rod, and the saddle member can include a hole to receive the anchoring member. The saddle member and the anchoring member can be coupled so as to allow multi-axial movement of the members. The anchoring member in one embodiment is a screw coupled to the hole of the saddle, and in another embodiment, the anchoring member is a hook. The offset member may be coupled to the saddle member to allow for offset connection of rods. Connection of individual rods can be accomplished by connecting the rods with the cross-link connector. The cross-link connector has an integrally formed cylindrical member that couples a pair of coupling portions together.Type: GrantFiled: March 1, 2010Date of Patent: August 20, 2013Assignee: Warsaw Orthopedic, Inc.Inventors: Robert A.

Publication number: 20070276379Abstract: An instrument is provided for reduction of a rod or other elongated member into an implant, such as a bone screw. In one embodiment, such an instrument includes a rod adjusting assembly pivotably attached to an implant holding assembly. The implant holding assembly can be pivotably connected to an implant, and the rod adjusting assembly is operable to move a rod toward or away from the implant holding assembly. In that embodiment, several motions are possible by the instrument so that relatively small or large movements of a rod with respect to an implant may be made.Type: ApplicationFiled: February 2, 2007Publication date: November 29, 2007Inventors: Keith Miller, Alan Rezach, Greg Denzer, Christopher Shaffrey, Marcel Dvorak, Charles Fisher, Jeff Wang, Ricardo Sasso

Publication number: 20070055245Abstract: Prostheses and methods for repair of cervical fact joints. In one aspect, the articulating surfaces of the natural facets of a facet joint are removed only a sufficient amount to allow the insertion of flat or slightly curvilinear portions of prostheses therebetween in an overlapping relationship. The portions are so inserted and the prostheses mounted by attachment to adjacent vertebrae. Also, a single natural facet may be similarly repaired with a single prosthesis. In another aspect, the invention provides a single prosthesis that is useful in repairing articulating surfaces in more than one cervical facet joint.Type: ApplicationFiled: October 3, 2006Publication date: March 8, 2007Inventors: Ricardo Sasso, Kevin Foley

Patent number: 6980849Abstract: Instrumentation and methods are provided for performing image-guided spinal surgery using an anterior surgical approach. In one embodiment, the method comprises providing a surgical navigation reference device, mounting the reference device to bone at a location remote from the spinal column and in a substantially fixed position relative thereto, accessing a portion of the spinal column from an anterior direction, and performing an image-guided surgical procedure on the spinal column using an anterior surgical approach. In another embodiment, the mounting of the reference device comprises anchoring the reference device to a portion of the patient's pelvic bone, and more specifically the anterior region of the iliac crest. In a further embodiment, the image-guided surgical procedure comprises a spinal implantation procedure wherein a spinal implant is inserted into an intervertebral opening formed along the lumbar region of the spinal column using an anterior surgical approach.Type: GrantFiled: July 8, 2003Date of Patent: December 27, 2005Inventor: Ricardo Sasso
