Our family cannot thank these doctors enough. They are simply miracle workers. We have been very happy with our son's care after his 78/50 degree scoliosis was corrected. If you are considering any form of scoliosis treatment or know someone who is, you must consider this team!

This group of surgeons are the greatest! They are experts and very helpful through out the whole process. My daughter is approaching her 1 year post ASC surgery and she is doing great. No pain and went from 60+ lumbar and 48 thoracic curves to 7.8 lumbar and 13.7 thoracic. I am so thankful for this group of surgeons!

Hands down the most talented, pioneering, thoughtful, and professional team for scoliosis correction. Our daughter was diagnosed with a 47deg Scoliosis at age 11. After meeting with many fine professionals, all recommending old-style fusion surgeries, we met with Dr. Betz and his team who offered an advanced approach (Anterior Scoliosis Correction), which keeps the spine flexible, with much quicker recovery time (2w out of bed, ~2mo for complete recovery), minimal scarring, and zero pain/discomfort post recovery. The team's bedside manners are amazing, before, during hospitalization, and after. Their support team is just as amazing, which is super appreciated with all the parental stress they have to deal with. Highly recommended.

The Institute for Spine and Scoliosis performed a truly miraculous surgery for my teenage son. Drs. Antonacci, Betz & Cuddihy are not only extremely talented leaders in their field, they are incredibly kind and caring. Such a rare combination these days, and we are forever thankful we found them!

We coudn' be happier with our decision to haven't our daughter's surgery with the ABC team. The hospital nurses and staff were amazing and the surgery was more successful than we imagined. We are 4 months post surgery and my daughter is doing great. She was back to school after 4 weeks and back to running after 6 weeks. We are very thankful to have found this fusion-less option.

Wonderful team of Dr.'s who have changed our daughter's life.

We have been up and down the east coast and these doctors are, from our experience are the best. We are so blessed to have found them.

“ASC by Drs. ABC is our multi-year, multi-generational advancement  of our original techniques of Anterior Fusion, VBT, and Stapling since 2013, which we now find vastly superior to posterior metal rod fusion in our practice. Because of our pioneering evolution (four U.S. Technique Patents) of ASC by Drs.ABC, there’s virtually no curve that in our opinion wouldn’t be better served with ASC by Drs. ABC over posterior metal rod fusion which by design destroys 100% of the functionality of your back muscles” — Dr. A.

a World-Renowned Surgeon

Dr. M. Darryl Antonacci MD FACS, Lead Surgeon and Founder, Institute for Spine & Scoliosis

In 2013 Drs. ABC coined the term ASC by Drs. ABC to distinguish their modified anterior scoliosis correction from what they considered was the severely limited first-generation techniques of VBT, as well as posterior metal rod fusion surgery which destroys your back muscles.  Now well after over 830 cases and multi-generational advancements of this back muscle sparing surgery, our peer reviewed published data is proving the point: the future of VBT and Metal Rods is dim, but the future for ASC by Drs. ABC is revolutionary in the world of Scoliosis Surgery.  Watch Dr. Antonacci’s 2023 interview on the concepts and success of ASC by Drs. ABC. 

Dr. Antonacci, is acknowledged as the premier scoliosis surgeon in the world for this technique and is years ahead of any of his contemporaries.  So much so that Dr. Antonacci’s patients come from all over the world (see map below).  About 18-20% of his practice are international patients, and 70% of his patients come from outside our local tri-state NY-NJ-PA area.  Patients are not the only ones coming now.  Drs. ABC have hosted some of the most well-regarded scoliosis surgeons in the World who have visited to watch Dr. Antonacci perform his ASC surgery (Surgeons from the United Kingdom, Germany, Italy, Spain, Turkey, Poland, and Greece to name a few).  

Among his many awards and recognitions, Dr. Antonacci has also twice been awarded the prestigious Russell A. Hibbs Award from the Scoliosis Research Society and continues to be a preeminent leader in the field of spinal surgery.

The Most Innovative Surgery For Scoliosis in 50+ years

Anterior Scoliosis Correction by Drs. ABC effectively replaces Posterior Metal Rod Surgery

Unlike posterior metal rod surgery which 100% scars your back muscles and destroy their function, Anterior Scoliosis Correction by Drs. ABC  100% saves your back muscles and function.  ASC by Drs. ABC can be performed on individuals aged 4 to 50 with curves measuring from 40 to over 90 degrees. 

ASC by Dr. ABC gets better corrections with greater clinical success (See our Data). Patients with severe curvatures of the spine or stiff and mature spines may be candidates for ASC by Drs. ABC just as much as young patients with flexible scoliosis. 

ASC by Drs. ABC is less invasive and muscle-sparing, with lower blood loss (<1-2% transfusion rates), negligible infection rates, and optimized recovery times compared to published Metal Rod results.  

Additionally, ASC by Drs. ABC preserve the growth, mobility, and flexibility of our patients’ spines. At six to eight weeks, most patients are released to sports, and live life unencumbered by a rigidly stiff spine (like they would with posterior metal rod spinal fusion). If you’re interested in learning if ASC is the ideal solution for you or your child, submit your case for review.  Any doubts, watch Dr. Antonacci’s interview above.
