Becker's Spine Review

44 patients who had already undergone the minimally invasive procedure as part of the study reported a solid fusion, and 73 percent reported pain reduction. e system consists of several threaded, cannulated implants and associated instrumentation that transfixes the sacrum and ilium, creating the appropriate conditions for bony growth across the SI joint. In June, Zyga received a new U.S. patent representing continued advancement of the SImmetry Sacroiliac Joint Fusion System. STALIF L (Centinel Spine). e STALIF L is the first FDA-cleared no-profile minimally invasive lateral integrated interbody system to feature a compressive lag screw fixation and Centinel Spine's proprietary anti-backout technology. Built on 30 years of STALIF heritage innova- tion, the STALIF L is an all-PEEK integrated interbody device that was developed to have multiple lordotic implant configurations that can closely match the patient's normal anatomy. e system is designed to optimize fixation with self-drilling, self-tapping screws and a variety of cage sizes. Tessys (joimax). Developed more than 15 years ago, Tessys is an endoscopic spine surgery system marketed in 45 countries for use in decompression procedures. Beginning in 2017, the American Medical Association assigned an endoscopic spine surgery code covering endo- scopic spinal cord and nerve root decompression, including laminoto- my, foraminotomy and discectomy. Tessys uses a lateral transforaminal endoscopic approach for surgeons to resect the herniated disc through the foramen intervertebrale. Surgeons can perform the procedure in the lateral or prone position under general anesthesia or moderated anesthesia care. In August, joimax opened a new Training and Educa- tion Center in Irvine, Calif., to instruct U.S. surgeons on endoscopic technique. underbolt Minimally Invasive Pedicle Screw System (Choic- eSpine). underbolt is a minimally invasive pedicle screw system that provides immobilization and stabilization of spinal segments as an adjunct to fusion in patients with degenerative disc disease, spondylo- listhesis, trauma, stenosis, deformity, tumor and pseudoarthrosis. e system includes a user-friendly rod reduction and a dovetail screw set to minimize head splay and cross threading. underbolt received FDA clearance in 2014 and Robert Knetsche, MD, performed the first proce- dure using the technology in April 2015. UNiD MIS Rod (Medicrea). e first minimally invasive spine surgery with Medicrea's patient specific UNiD MIS Rod was performed in July at Aurora-based University of Colorado Hospital. e rod is compat- ible with percutaneous and mini open applications and eliminates the need to modify implants intraoperatively. e company manufactures each rod specifically for the patient prior to surgery. Studies show the patient-specific rod can reduce rod breakage in adult spinal deformity patients. Viper Prime (DePuy Synthes). Unveiled earlier this year at Eurospine 2017 Congress, DePuy Synthes' Viper Prime is a minimally invasive pedicle screw system designed for fusion procedures. e system reduc- es instrumentation needed and steps required to insert percutaneous screws by combining the pedicle preparation instruments into one tool. Surgeons only need two instrument trays for Viper Prime procedures, which could make the back table easier to organize and reduce pro- cessing costs. A bench study conducted with Viper Prime showed a 33 percent reduction in pedicle screw insertion time compared with other minimally invasive techniques. Yeung Endoscopic Spine System. Anthony Yeung, MD, developed the Yeung Endoscopic Spine System in partnership with the Richard Wolf Instrument Company to perform selective endoscopic discectomy in patients with herniated, protruded, extruded and degenerative discs. Visualization through the endoscope allows surgeons to selectively remove portions of the herniated nucleus pulposus that contribute to the patient's pain. Dr. Yeung has trained several surgeons in using the FDA-cleared system and helped develop the Dr. Anthony T. and Eileen K. Yeung Endoscopic Spine Center at the University of New Mexico's Rio Rancho-based Sandoval Regional Medical Center, which also trains surgeons in the technique. n Allen Medical is an industry leader in patient positioning and surgical site access.
