Scoliosis is a condition characterised by the lateral (side-to-side) curvature of the normally straight spine, forming an "S" or "C" shape, as observed in X-rays.
These changes occur due to the wear and tear of the discs, which act as shock absorbers between the vertebral bodies of the spine, as we age. As the intervertebral discs undergo wear and tear, they can start to collapse or prolapse, resulting in reduced flexibility.
There are various types of scoliosis and causes for spinal curvature, including:
Scoliosis is not caused by carrying heavy objects (such as heavy school bags on one shoulder), sports or other physical activities, poor standing or sleeping postures, or dietary calcium deficiency.
Scoliosis affects children of all races but is more common in girls than in boys (ratio of 7:1).
In Singapore, the prevalence of adolescent idiopathic scoliosis in schoolgirls is 1.4% at 11–12 years of age and 2.2% at 13–14 years of age.Many signs of scoliosis are noticeable and can be detected in early childhood. These include:
Scoliosis cannot be corrected by learning to sit or stand up straight. Food or vitamin supplements and exercise programmes have also shown no significant value in treating the condition. Although about 10% of all male and female adolescents suffer from scoliosis, less than 1% have curves that require medical attention. Scoliosis can be mild, moderate or severe. Treatment may include one or a combination of the following:
Surgery is recommended for curves greater than 40 degrees in children and for curves greater than 50 degrees at any age. It is a common misconception that scoliosis does not progress after skeletal maturity. It has now been shown that if left untreated, large idiopathic curves above 50 degrees will continue progressing in adulthood.
Surgical treatment of scoliosis may be indicated for any of these reasons:
The most common surgical treatment for scoliosis is spinal fusion using special stainless steel/titanium rods, hooks, screws and bone graft to carefully straighten the curved portion of the spine. In suitable patients, the surgery can be achieved through thoracoscopic "keyhole" techniques that require only four to five small openings on the side of the chest. Using modern spinal instrumentation, scoliosis patients who have undergone surgery lead normal and independent lives and can participate in most or all forms of sports. However, during the initial few months post-surgery, patients are advised to gradually ease into physical activities.
