Scoliosis is a problem with your backbone, or spine, causing it to bend sideways and twist. Scoliosis can occur in either the upper back (thoracic), lower back (lumbar), or very rarely, in the neck (cervical region). Idiopathic scoliosis (scoliosis of an unknown cause) is the most common type of scoliosis in the United States. Eighty percent of diagnosed cases are of the idiopathic type. Idiopathic scoliosis is usually noticed at the onset of puberty and is more often seen in females. People with scoliosis often have uneven shoulders or hips, and a shoulder blade, which sticks out. Changes are especially noticeable when the person is bending over. Most scoliosis is found during school screening. Treatment If the spinal curvature progresses despite the use of conservative measures such as bracing, the doctor might recommend surgery called a "posterior spinal instrumentation and fusion" or PSIF. The purpose of this surgery is to halt progression of the curve and stabilize that portion of the spine. Doctors recommend surgery when the curve gets to a certain size, usually 45-50 degrees. Occasionally the patient will undergo surgery for curves less than this. If the curve is getting bigger and it's not treated, it can cause physical deformities and possibly lead to back, lung and heart problems in later years. Our Scoliosis physicians support school screening programs through nursing education. We provide physician coverage for Scoliosis clinics throughout the Northwest, including Alaska, Washington, Montana, and Idaho. We are members of the Scoliosis Research Society, and are actively involved in research related to Scoliosis and spinal deformities in children and adults.
