Kyphosis is a spinal disorder in which an excessive outward curve of the spine results in an abnormal rounding of the upper back. The condition is sometimes known as "roundback" or—in the case of a severe curve—as "hunchback." Kyphosis can occur at any age, but is common during adolescence.
In the majority of cases, kyphosis causes few problems and does not require treatment. Occasionally, a patient may need to wear a back brace or do exercises in order to improve his or her posture and strengthen the spine. In severe cases, however, kyphosis can be painful, cause significant spinal deformity, and lead to breathing problems. Patients with severe kyphosis may need surgery to help reduce the excessive spinal curve and improve their symptoms.
Types of kyphosis
There are 3 types (causes) of kyphosis.
Postural Kyphosis: the most 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.
Congenital Kyphosis: occurs when the spinal column fails to develop normally while the baby is in utero. The bones may not form as they should or several vertebrae may be fused together. Congenital kyphosis typically worsens as the child ages.
Scheuermann's Kyphosis: 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, several 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.
