Dr. Antonacci has extensive surgical experience in adults and children with particular interest in scoliosis surgery and complex reconstructive spine surgery including minimally invasive fusion techniques.  He uses cutting edge surgical techniques such as minimally invasive, muscle sparing fusion surgery which drastically reduces blood loss, shortens hospital stays and provides faster recoveries.
