Our Scoliosis Methodology

A conservative treatment philosophy drives all of our clinicians. We will advocate for nonoperative scoliosis treatment unless it has been shown to be ineffective or if surgery has been proven to be the best treatment option.

Our EOS Imaging System

Many parents express concern about exposing their child or teenager to radiation during an X-ray or CT scan. We are physicians, but we are also parents, so we fully appreciate their concern.

Using only about 10% of the radiation of traditional X-rays, EOS imaging is a low-dose x-ray, 2D/3D imaging technology that provides a detailed x-ray image of bones with more accurate information than traditional x-rays. The EOS system allows for more accurate assessment and—as a result—better, more precise treatments.

We are the only pediatric orthopedic practice and scoliosis center in northern New Jersey to offer the EOS imaging technology.
