Types of & :
1. Postural Kyphosis
Postural kyphosis, the common type of kyphosis, usually becomes noticeable during adolescence. It is noticed clinically as poor posture or slouching but is not associated with severe structural abnormalities of the spine.
The curve caused by postural kyphosis is typically round and smooth and can often be corrected by the patient when they are asked to stand up straight.
Postural kyphosis is more common in girls than boys. It is rarely painful, and, because the curve does not progress, it does not usually lead to problems in adult life.
2. Scheuermann's Kyphosis
Scheuermann's kyphosis is named after Danish radiologist who first described the condition.
Like postural kyphosis, Scheuermann's kyphosis often becomes apparent during the teen years. However, Scheuermann's kyphosis can result in a more severe deformity than postural kyphosis.
Scheuermann's kyphosis is caused by a structural abnormality in the spine. In a patient with Scheuermann's kyphosis, an X-ray from the side will show that, rather than the normal rectangular shape, three or more consecutive vertebrae have a more triangular shape. This irregular shape causes the vertebrae to wedge together toward the front of the spine, decreasing the normal disk space and creating an exaggerated forward curvature in the upper back.
The curve caused by Scheuermann's kyphosis is usually sharp and angular. It is also stiff and rigid. Unlike a patient with postural kyphosis, a patient with Scheuermann's kyphosis is not able to correct the curve simply by standing up straight.
Scheuermann's kyphosis usually affects the thoracic spine but occasionally develops in the lumbar spine. The condition is more common in boys than girls.
3. Congenital Kyphosis
Congenital kyphosis is present at birth. It occurs when the spinal column fails to develop normally while the baby is in the womb. The bones may not form as they should, or several vertebrae may be fused together.
