Scoliosis means that the spine curves from side to side rather than running straight down the back. The spine is made of bones called vertebrae that normally stack one on top of the other in a straight line. The bones in the upper back are called thoracic vertebrae. This is the most common site for scoliosis. The bones in the lower back are called lumbar vertebrae. Scoliosis occurs less often in the lumbar vertebrae.
Scoliosis develops gradually. Scoliosis is usually noticed just before or during puberty when a child goes through a growth spurt. Females get scoliosis more often than males. Often parents do not notice the gradual changes caused by scoliosis. The curvature is usually discovered by a healthcare provider. Occasionally, scoliosis is diagnosed during infancy and is treated sooner.
There are many causes of scoliosis. Sometimes vertebrae are incompletely formed or misshapen. Sometimes children who have legs of different lengths develop a curvature of the spine. Other times, diseases cause scoliosis. In children and teens the cause is most often not known.
When a cause for scoliosis cannot be found, it is called idiopathic scoliosis. In idiopathic scoliosis some of the vertebrae are rotated because the muscles attaching the vertebrae to the ribs may not be pulling with equal force. One set of rib muscles pulls harder causing the vertebrae to twist and move out of a straight line down the back. This may also cause the ribs on one side of the back to stick out more, causing a hump.
At first, the symptoms are painless and not always easy to recognize. Someone with scoliosis may:
The healthcare provider will take a medical history to see if there may be a cause for the scoliosis. The provider will do a physical exam, checking the back, chest, shoulders, pelvis, legs, feet, and skin. The curve of the spine may be measured during the exam. X-rays can be taken to measure the curvature more precisely.
If your child has a slight curvature, he or she just needs regular checkups by the healthcare provider. If the curvature continues to get worse, your provider will refer your child to a bone doctor (orthopedist). The orthopedist may recommend braces and molded plastic shells called orthoses. Orthoses may slow down further curving of the spine but do not correct a curvature that is already there. Sometimes orthoses do not slow the curving enough to prevent serious problems and surgery is needed.
The curvature in the back will never go away. However, many people have no symptoms or problems from their scoliosis. When problems do occur, they will last until the symptoms are treated. How well the treatment works depends on the type of treatment and the severity of the problem.
Most children are adolescents or teenagers when scoliosis is diagnosed. Often they are self-conscious about their problem. Help your child understand the importance of carefully following the recommended treatment. Counseling or a support group might be helpful.
