Our Unique Advantage: Robotic-Assisted Spine Surgery
ONYX is one of only a few ambulatory surgery centers in the country that offers robotic-assisted spine surgery using the advanced Globus ExcelsiusGPS® system. This innovative technology enhances surgical precision, reduces tissue damage and blood loss, and helps patients recover faster with fewer complications.
When surgery is necessary, we prioritize minimally invasive techniques that shorten recovery times and lower risks, because better outcomes start with smarter tools and specialized care.
