New studies highlight benefits of EOS 3D imaging in assessing corrective bracing for scoliosis

EOS imaging (NYSE Euronext, FR0011191766-EOSI), the pioneer in orthopaedic 2D/3D imaging, have announced that two new studies supporting the use of its 3D imaging technology in assessing the impact of bracing for adolescent idiopathic scoliosis (AIS) have been published online in the European Spine Journal. Bracing is the preferred therapy for progressive scoliosis with a Cobb angle (curve) in the range of 20° to 45°, though current data on its efficacy in correcting spinal curvatures are inconclusive.

The first study, conducted by the Laboratoire de Biomécanique in Paris, France and published in June, used the EOS® System to obtain 3D images of the spines of 30 patients with AIS. It showed that there is high variability among individual patients in terms of the effectiveness of bracing on 3D Cobb angle and other key spinal parameters.[1] The second study, by clinicians at the Hospital for Sick Children in Toronto, Ontario and published in July, used 3D imaging provided by the EOS System to evaluate the immediate effects of two common braces on the spine, concluding that braces do differ in their treatment impact.[2]

Researchers in both studies noted that the low dose 3D imaging enabled by the EOS System allows for immediate control of the bracing as well as for the assessment of the disease progression and corrective impact of bracing treatment.

Marie Meynadier, CEO of EOS imaging, said, "Wearing a corrective brace can be quite challenging for young scoliotic patients, most of them teenage girls. We are pleased that the low dose and 3D capacity of the EOS System may offer a new tool for post-bracing control, as well as for the assessment of the efficacy of this treatment for a condition that affects millions of children and adults worldwide. The research demonstrates yet another clinical application in which the EOS System offers a new and superior method to evaluate a patient's specific orthopaedic condition and guide the treatment plan. Studies such as these continue to build awareness of the role our technology can play in advancing the understanding of spinal pathology."
