ScoliosisScoliosis Surgery

What is adolescent idiopathic scoliosis?

Adolescent idiopathic scoliosis is an abnormal C-shaped or S-shaped curvature of the spine. The curvature of the spine is measured by the Cobb angle. Small spinal curves occur with similar frequency in boys and girls, but girls are more likely to have a progressively larger scoliotic curve requiring treatment.

 

What are the symptoms?

Symptoms of adolescent idiopathic scoliosis include back pain, unequal leg lengths, uneven hips, uneven shoulders (one shoulder appears higher than the other), abnormal gait, as well as breathing difficulties when the rib cage puts pressure on the lungs. When left untreated, the deformity might progress significantly.

 

How is adolescent idiopathic scoliosis treated?

For milder cases, physicians may recommend nonsurgical treatment such as bracing. Braces are usually worn for several hours daily. This can be effective if the child is still growing and has a cobb angle between 25° and 45°.

 

In cases which are progressive or the cobb angle is greater than 45°, a physician may recommend surgery to straighten and fixate the spine, which is achieved by placing implants such as screws, rods, hooks, and wires in and along the spine.

 

Scoliosis-Treated-Through-MazorWhat are the advantages of treatment with Mazor Robotics Renaissance as compared to other methods?

Surgical treatment of adolescent idiopathic scoliosis requires planning and precision. Each scoliotic curvature has unique challenges, and often the patient’s vertebrae are deformed, twisted and abnormally small, which makes for a challenging surgery.

 

Renaissance® provides increased safety and precision in corrective surgery. It allows surgeons to plan ahead before entering the operating room; Mazor Robotics advanced 3D planning software is used before surgery to create the ideal procedure for each patient’s condition. During the operation, the physician does the actual work; Renaissance® guides the surgeon’s tools according to the predetermined blueprint to place the implants safely and with the highest level of accuracy in the exact planned locations.

 

A clinical study presented at a Pediatric Society of North America (POSNA) conference reported 99.6 percent clinical acceptance of screws placed in 120 adolescent scoliotic surgery cases performed with Mazor Robotics Renaissance® Guidance System.1
