June is the Scoliosis Awareness Month that aims at highlighting the growing need for education, early detection, and awareness regarding scoliosis and its prevalence within the community. It unites scoliosis patients, families, physicians, clinicians, institutions, and related businesses in collaborative partnerships of local activities, events, and grassroots networking throughout the month.
Scoliosis is an abnormal side-to-side curvature of the spine. The spinal curve may develop as a single curve (shaped like the letter C) or as two curves (shaped like the letter S).� It is often defined as spinal curvature in the �coronal� (frontal) plane. While the degree of curvature is measured on the coronal plane, scoliosis is actually a more complex, three-dimensional problem which involves the following planes:
The coronal plane is a vertical plane from head to foot and parallel to the shoulders, dividing the body into anterior (front) and posterior (back) sections. The sagittal plane divides the body into right and left halves. The axial plane is parallel to the plane of the ground and at right angles to the coronal and sagittal planes.
Scoliosis is hereditary among the people with scoliosis who are more likely to have children with scoliosis; however, there is no correlation between the severity of the curves from one generation to the next. In children and teens, scoliosis often does not have any noticeable symptoms and may not be noticeable until it has progressed significantly. Most cases of scoliosis are mild, but some spine deformities continue to get more severe as children grow. Severe scoliosis can be disabling. An especially severe spinal curve can reduce the amount of space within the chest, making it difficult for the lungs to function properly.� The most common form of scoliosis appears in adolescents. It is known as adolescent idiopathic scoliosis. It can affect children from the age of 10 years.�
The symptoms can include the head is slightly off center, the ribcage is not symmetrical, so the ribs may be at different heights and one hip is more prominent than the other. Furthermore, in infants, symptoms can include: a bulge on one side of the chest, consistently lying curved to one side (in babies), Problems with the heart and lungs, leading to shortness of breath and chest pain.
According to the American Association of Neurological Surgeons (AANS), about 80 percent of scoliosis cases have no identifiable cause. The condition is often diagnosed during the first seven years of a child�s life.
There are certain risk factors associated with scoliosis include: age, gender & genetics etc. are explained below:
Scoliosis is confirmed through a physical examination, an x-ray, spinal radiograph, CT scan or MRI. The curve is measured by the Cobb Method and is diagnosed in terms of severity by the number of degrees. A positive diagnosis of scoliosis is made based on a coronal curvature measured on a posterior-anterior radiograph of greater than 10 degrees. In general, a curve is considered significant if it is greater than 25 to 30 degrees. Curves exceeding 45 to 50 degrees are considered severe and often require more aggressive treatment.
A standard exam that is sometimes used by pediatricians and in grade school screenings is called the Adam's Forward Bend Test. During this test, the patient leans forward with his or her feet together and bends 90 degrees at the waist. This is a simple initial screening test that can detect potential problems, but cannot determine accurately the exact type or severity of the deformity. The tests are required for an accurate and positive diagnosis.
Doctor would check the spine curvature and whether the shoulders and waist area are symmetrical or not.
Imaging tests doctor may order to look for scoliosis include:
Treatment of scoliosis is based on the severity of the curve and the chances of the curve getting worse. Certain types of scoliosis have a greater chance of getting worse, so the type of scoliosis also helps to determine the proper treatment. There are three main categories of treatment i.e. observation, bracing (for example, thoracolumbosacral orthosis or TLSO back brace), and surgery. Consequently, there are treatments available that do not involve surgery, but in some individuals, surgery may be their best option.
In many children with scoliosis, the spinal curve is mild enough to not require treatment. However, if the doctor is worried that the curve may be increasing, he or she may wish to examine the child every four to six months throughout adolescence.
In adults with scoliosis, X-rays are usually recommended once every five years, unless symptoms are getting progressively worse.
Braces are only effective in patients who have not reached skeletal maturity. If the child is still growing and his or her curve is between 25 degrees and 40 degrees, a brace may be recommended to prevent the curve from progressing. There have been improvements in brace design and the newer models fit under the arm, not around the neck. There are several different types of braces available. For optimal effectiveness, the brace should be checked regularly to assure a proper fit and may need to be worn 16 to 23 hours every day until growth stops.
In children, the two primary goals of surgery are to stop the curve from progressing during adulthood and to diminish spinal deformity. Most experts would recommend surgery only when the spinal curve is greater than 40 degrees and there are signs of progression. This surgery can be done using an anterior approach (through the front) or a posterior approach (through the back) depending on the particular case.
A number of factors can lead to increased surgical-related risks in older adults with degenerative scoliosis. These factors include the following: advanced age, being a smoker, being overweight and the presence of other health/medical problems. In general, both surgery and recovery time are expected to be longer in older adults with scoliosis.
Following surgical procedures are used for the treatment of scoliosis
The benefits of surgery should always be weighed carefully against its risks. Although a large percentage of scoliosis patients benefit from surgery, there is no guarantee that surgery will stop curve progression and symptoms in every individual.
