EOS is a platform that includes an imaging system, EOSedge®, and digital software, EOS Insight™, that provides medical professionals with high-quality images and data to better understand each individual patient’s unique anatomy and condition. The images and information generated by EOSedge, which is processed by EOS Insight, is used by your surgical team to make decisions, and develop treatment plans for orthopedic medical conditions, such as:
Degenerative Spine/Disc Disease (DDD)
Adult Spinal Deformity (ASD)
Adolescent Idiopathic Scoliosis (AIS)
Limb-length discrepancy
Hip and knee osteoarthritis.
Hip dysplasia
Balance and posture complications
Bowlegs and Knock-Knees
General orthopedic conditions
What should I expect during my EOSedge exam?
EOSedge was designed to comfortably accommodate most children and adults. The system captures two X-ray scans of your body at the same time, one from the front and one from the side. The exam is done in a standing or seated position with the goal of giving physicians a depiction of your natural, weight-bearing posture.
The exam will begin when the radiology technician brings you into the EOSedge room. Once in the room, you may be asked to remove shoes, jewelry, and any metal objects. You will be asked to stand or sit on the lowered orange platform. Once you are in the appropriate position, two pods containing the X-ray tubes will lower and raise to acquire the images, taking around 20 to 30 seconds. The radiology technician will notify you once the images are completed and will then escort you off the platform.
What are the benefits of an EOSedge exam?
EOSedge is a low dose imaging system. Each exam is taken in consideration of the “As Low As Reasonably Achievable” (ALARA) radiation dose principle1, providing up to 80% overall radiation reduction per exam compared to conventional digital radiography.2 To achieve this, EOSedge uses a dose adjustment feature called Flex Dose™,3 automatically adjusting the dose based on each patient’s body composition and physical build. Flex Dose minimizes radiation exposure while still delivering high-resolution images. For patients who require frequent follow-up imaging, such as pediatric patients with scoliosis, an additional dose reduction feature called Micro Dose™ can be used, providing up to a 96% dose reduction compared to digital radiography2, resulting in the equivalent of less than a week’s worth of natural radiation exposure. 3
How will my doctor use the information?
Your physician will review the images and other diagnostic information about your skeletal alignment. The images and alignment assessment details will assist your physician in determining the best course of action for your proposed treatment, enabling them to develop a personalized plan, and to subsequently evaluate the outcome of any received treatments.
What is “global alignment” and why is it important?
Over the past decade, there have been numerous clinical publications on the importance of global skeletal alignment.4-6
Imagine your body is like a puzzle made up of different pieces, and each body part, for example your spine, hip, or knee, represents a piece of the puzzle. Global alignment allows your doctor to make sure all the pieces of the puzzle fit together just right, so your body can be balanced and work as smoothly and efficiently as possible. It’s about ensuring that everything in your body is properly aligned, so you feel your best and can function at your optimal level.
The EOS Insight platform provides your doctor with a thorough understanding of your global alignment by providing not only the appropriate images, but also the diagnostic information needed to make treatment plans and evaluate their effectiveness. Just like how a well-aligned puzzle looks neat and complete, global alignment aims to keep your body in harmony, helping you stay healthy and active.

Scoliosis-specific exercises provide significant benefits both before and after vertebral body tethering surgery. Prior to surgery, these exercises help strengthen muscles around the spine, improve flexibility, and optimize posture, which can potentially reduce the severity of the curvature and prepare the body for the procedure. Following surgery, scoliosis-specific exercises play a crucial role in promoting healing, restoring mobility, and preventing muscle imbalances or stiffness.
By adhering to a tailored exercise regimen, patients can support the success of the surgery, enhance their recovery process, and maintain optimal spinal function and alignment in the long term, leading to improved overall well-being and quality of life.
Scoliosis-specific exercises offer important benefits both before and after spinal fusion surgery for scoliosis. Before surgery, these exercises can help improve flexibility, strength, and posture, which may ease symptoms and prepare the body for the procedure. After surgery, these exercises become even more crucial. They aid in regaining strength, promoting healing, and preventing muscle stiffness or weakness that can occur due to the surgical procedure.
By following a tailored exercise program, patients can enhance their recovery, maintain spinal alignment, and improve overall mobility and function, ultimately supporting their long-term well-being and quality of life.
Pregnancy can pose unique challenges for women with scoliosis, a condition where the spine curves sideways. While many women with scoliosis have healthy pregnancies, the added weight and changes in posture during pregnancy can sometimes exacerbate back pain or discomfort. It’s important for women with scoliosis to communicate with their healthcare providers throughout pregnancy to manage any pain or concerns.
Scoliosis Specific physical therapy, proper posture, and sometimes support devices can help alleviate discomfort and promote a smoother pregnancy experience. With proper care and monitoring, most women with scoliosis can enjoy a healthy happy pregnancy and delivery.
Aging adolescent idiopathic scoliosis occurs when the curvature of the spine, which developed during adolescence, progresses or worsens with age. This type of scoliosis affects individuals who had scoliosis as teenagers, and it may cause pain, stiffness, and difficulty with daily activities as they get older. In contrast, adult degenerative scoliosis develops later in life due to wear and tear on the spine’s discs and joints.
It often leads to spinal curvature and can cause back pain, nerve compression, and changes in posture. Treatment options for both conditions may include physical therapy, pain management, and in severe cases, surgery to stabilize the spine and improve quality of life. Early diagnosis and appropriate management are essential to minimize symptoms and maintain spinal health
Juvenile idiopathic scoliosis, (JIS) is a type of spinal curvature that occurs in children under the age of 10. Unlike adolescent scoliosis, it may not be related to growth spurts. It affects both boys and girls equally and can lead to uneven shoulders, waist, or hips. Early detection is essential as it allows for timely intervention to prevent the curve from worsening. The research and outcomes for JIS are different than AIS. Treatment options may include observation, physical therapy, bracing, or, in severe cases, surgery.
Early Onset Scoliosis, (EOS): Early onset scoliosis is a condition where the spine curves sideways in children under the age of 5. Unlike scoliosis in older children, the cause of early onset scoliosis can be related to congenital spine abnormalities, neuromuscular conditions, or chest wall deformities. This type of scoliosis can affect a child’s breathing and lung development if left untreated. Treatment options may include observation, bracing, growth-friendly surgeries, or a combination of these, aiming to manage the curve and support healthy spine growth as the child grows. Early diagnosis and intervention are crucial to prevent potential complications and promote better long-term outcomes.
Adolescent idiopathic scoliosis is a condition where the spine curves during a growth spurt in teenagers. It affects around 2-3% of adolescents, typically girls, aged 10-18 and will appear on an xray like a C or S shape. While the cause is unknown, genetics may play a role, and thus can be present in the family history.
Early detection through screenings is crucial, as mild cases may not cause symptoms but can progress over time. Treatment options include observation, physical therapy, bracing, or in severe cases, surgery, aiming to prevent curve progression and maintain spinal alignment for a healthy, active life.
