Kyphosis

Kyphosis is an abnormal forward curvature of the spine in the sagittal plane, derived from the Greek word kyphos, meaning bent. Both physiological and pathological types of kyphosis are distinguished.

Physiological kyphosis, which involves the entire spine, is present only in newborns and infants During the first three months of life. Subsequently, the spine straightens; however, upon assuming an upright posture when the child begins to walk, physiological lordosis develops in the lumbar region, while kyphosis persists throughout Life in the thoracic region.

Pathological kyphosis can be congenital or acquired. Congenital kyphosis is caused by Developmental anomalies of the spine, such as accessory wedge-shaped vertebrae, fusion of thoracic vertebrae, and others. Acquired kyphosis occurs in Rickets, following vertebral osteochondropathy (Calvé disease), Ankylosing spondylitis (Bechterew's disease), Tuberculous Spondylitis, and similar conditions, as detailed in the relevant sections.

In clinical practice, cases of juvenile and Senile kyphosis are frequently encountered.
