Minimally Invasive System Helps Save Muscle Tissue and Reduces Recovery Time
Philadelphia - Medtronic, Inc. announced the U.S. market availability of the CD HORIZON(R) SEXTANT(R) II System, a surgical instrumentation system that offers a minimally invasive method of placing implants that provide stabilization during spinal fusion surgery. The CD HORIZON SEXTANT II System delivers rods and screws percutaneously into the backs of patients suffering from degenerative disc disease, herniated or ruptured discs, misaligned vertebrae or spinal fractures. The implants stabilize the back to encourage fusion.
As part of a modern spinal fusion procedure, the CD HORIZON SEXTANT II System allows surgeons to place the implants into the back of the spine without major muscle and tissue disruption usually associated with traditional fusion surgeries. An arc, resembling a sailor's sextant, places the rod through the skin and into the heads of the screws. Because the surgery is minimally invasive, the patient recovery time is usually faster than traditional spinal fusion surgery. The CD HORIZON SEXTANT II System may also leave patients with smaller scars, usually only 1 inch long.
For surgeons, the CD HORIZON SEXTANT II System reduces the number of operating room procedural steps and provides user-friendly instrumentation. The rod inserter arc is larger than previous editions and the screw extenders achieve a stronger connection with the CD HORIZON(R) LEGACY(TM) Cannulated pedicle screws used in the procedure.
"The CD HORIZON SEXTANT II System is a next generation innovation offering a streamlined process that provides a truly percutaneous solution for surgeons treating patients with degenerative spinal disorders in their thoracic or lumbar regions," said Dr. David Rouben of River City Orthopedic Surgeons in Louisville, Ky.
CD HORIZON SEXTANT II System is part of Medtronic's comprehensive Minimal Access Surgical Technique (MAST(TM)) Platform that includes METRx(TM) System, MAST QUADRANT(TM) Retractor and Interbody Options. Integrated NIM-SPINE(TM) System neuromonitoring accessories and MAST FLOURONAV(R) System facilitate safe pedicle screw placement.
The screws used in the CD HORIZON SEXTANT II System are made of titanium and utilize a 5.5mm rod. Screw diameters are available in 4.5mm, 5.5mm, 6.5mm, 7.5mm and 8.5mm options with lengths that run from 30mm to 60mm. Since the launch of CD HORIZON SEXTANT(R) Spinal System in 2002, more than 20,000 successful procedures have been performed.
The CD HORIZON SEXTANT II System received U.S. Food and Drug Administration 510(k) clearance in May 2005 for use as a posterior spine thoracic/lumbar system intended for use in the following indications: (1) degenerative disc disease (as defined by back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), (2) spinal stenosis, (3) spondylolisthesis, (4) spinal deformities (i.e., degenerative scoliosis, kyphosis, and/or lordosis), (5) fracture, (6) pseudarthrosis, (7) tumor resection, and/or (8) failed previous fusion.
