Tri-City Moves to Forefront in California in the Use of Mazor Robotic Surgery

Tri-City Medical Center has become one of the nation’s leading hospitals in robotic surgery.  Using the Mazor Renaissance guidance system, the medical center has performed 201 Mazor Robotic surgeries over an 18-month period.  This number is unprecedented in California.  In addition, no patient has returned for revision surgery. In addition, the medical center is now one of the first hospitals worldwide to use an enhancement to that system that allows surgeons to immediately verify the placement of implants, significantly diminishing the need for follow-up procedures.


Mazor Robotics’ Renaissance™ is a specially-designed surgical guidance system which allows surgeons to perform safer and more accurate spine surgeries. For patients, this means better clinical outcomes with less pain, fewer complications, and shorter recovery time. Renaissance is in daily use in leading hospitals with thousands of successful cases worldwide.


“Superior surgical outcomes, and physician and patient demand for the technology have led to a 30 percent increase in the number of patients receiving spine care at Tri-City Medical Center,” said Tri-City Medical Center interim CEO Casey Fatch. “Tri-City Medical Center remains on the cutting edge in embracing technology that advances the quality of care we provide to patients with back pain.”


“In the past,” said Neville Alleyne, M.D., president of Tri-City’s Orthopedic and Spine Institute, “surgeons performing open spine surgery have accessed the spine by making a large incision in order to allow a full, direct-field-of-vision and access for the surgeon's hands and tools. In minimally invasive surgery, surgeons make much smaller skin incisions.”


He added, “When Tri-City Medical Center surgeons use the Renaissance, they actually map out the surgery on a computer using CT images of the patient. Patients benefit from high levels of accuracy, low intraoperative exposure to radiation and the advantages of minimally invasive surgery.”


Earlier this year, Dr. Alleyne and fellow surgeon Payam Moazzaz, M.D., participated in a field evaluation of C-OnSite, which enables fast, low-radiation, intra-operative 3D verification of implant placement.

"Renaissance C-OnSite combines the enhanced accuracy of robotic guidance with actionable, intra-operative verification of screw positioning for immediate evaluation and correction," said Ori Hadomi, CEO of Mazor Robotics. "This offers the potential to reduce revision cases due to the misplacement of pedicle screws, which in freehand surgery occurs in approximately 10 percent of screw placements."  

The current standard of care in spine surgery is a post-operative CT to verify accurate placement of pedicle screws. But it occurs after the surgery has been completed, so significant misplacements necessitate a revision surgery. 

"C-OnSite is a quantum leap forward for spine surgeons and their patients," said Dr. Moazzaz. "C-OnSite makes Renaissance a full solution for the spine surgeon, from pre-op planning through post-op verification, with the added benefit of delivering post-op information during the surgical procedure.”
