Drs. M. Darryl Antonacci, Randal R. Betz and Laury A. Cuddihy are world-class scoliosis surgeons treating local New Jersey families and patients with scoliosis from all over the world.

A board-certified spine and scoliosis surgeon, Dr. Antonacci has extensive surgical experience with adults and children, and is a world leader in scoliosis surgery.

The physicians at the Institute for Spine and Scoliosis are pioneers and leaders in the field of scoliosis both nationally and internationally, and focus on pediatric scoliosis and spondylolisthesis. Drs. Antonacci, Betz and Cuddihy restore function of the spine with near normal contour and movement—and significantly faster recovery—by utilizing surgical methods that are less invasive than traditional approaches.

Following in the footsteps of his four older siblings who are all physicians, Dr. Antonacci chose to specialize in scoliosis after seeing a need for minimally-invasive solutions with less scarring and better outcomes. He developed the Anterior Scoliosis Correction (ASC) procedure, a flexible approach for correcting the scoliosis curve that leaves minimal scarring. The muscle-sparing surgery helps maximize flexibility while straightening small, large and even stiff curves in both growing and mature patients.

“The ASC procedure is the most advanced minimally-invasive treatment for correcting the scoliosis curve. It gives a child the ability to continue an active life with flexibility,” he says.

The practice provides a nurturing, supportive environment for families. “We never rush anyone, and always take the time to answer questions,” Dr. Antonacci says. The practice also offers a private Facebook group as a support forum for families to ask questions and share experiences.

“Everyone’s nervous when dealing with such a personal procedure, and parents have a lot of questions about pre-and post-care,” he says. “We’re not only there to support patients in the office or hospital, but my team and I are constantly checking in with our families via calls, text messages and emails.”

Dr. Antonacci’s two daughters and son are working with the practice to establish the Antonacci Foundation, a fundraising organization that’ll help families afford the hospital costs associated with the ASC procedure. “We love interacting with families and children in the office and being there for them throughout the surgery process and on their road to recovery,” he says.

Dr. Antonacci has studied and taught at some of the world’s most prestigious universities for spinal surgery. He maintains positions as attending physician in the department of orthopaedic surgery at Saint Peter’s University Hospital; clinical assistant professor of orthopaedic surgery at Mount Sinai Medical Center, and attending physician in the department of orthopaedic surgery at the University Medical Center of Princeton.

Drs. Antonacci, Betz, Cuddihy and their team recently received the Bishop’s Award from Saint Peter’s Healthcare System for their pioneering work in less invasive and complex spine surgery. Dr. Antonacci is among only a few individuals to receive the Russell Hibbs Award for Research from the Scoliosis Research Society twice.

A Diplomate of the National Board of Medical Examiners, Dr. Antonacci is a Fellow of the American Academy of Orthopaedic Surgery, American College of Surgeons, Scoliosis Research Society, Cervical Spine Research Society and the North American Spine Society. “It’s very rewarding to know that our treatments make such a huge impact in children’s lives,” he says.

"Dr. Antonacci is a wonderful skilled surgeon who performed surgery on my 15-year-old son. He's the best, and I'll be forever grateful to him and his team for giving my son's life back to him! " Lisa, Macomb

"The whole team was informative, supportive and incredibly knowledgeable. I was certain my daughter was in great hands. " Tracey, Carthage

"Dr. Cuddihy came to see my daughter every day while she was in the hospital for seven days after her spine surgery. Her surgery was out of state. If I had a question, I could text the doctor and she'd get back to me that day! Her compassion for her patients is just amazing." Danielle, Sterling Heights

"Dr. Cuddihy was part of the physician team that did surgery on my daughter that no one else was capable of doing. She was also very supportive and friendly to a scared 12-year-old. Her surgery was four years ago and Dr. Cuddihy still stays in touch, even though we're out of state. " Susan, Matthews
