A loss of the normal spinal alignment is referred to as a spinal deformity. Scoliosis (abnormal sideward bending of the spine) and kyphosis (abnormal forward bending of the spine) are the two common types of deformity. Some of these deformities can progress and need treatment.
Spinal deformities could result from a variety of causes and in a majority of adolescents, the exact cause is unknown (idiopathic). Other causes for a spinal deformity are vertebral anomalies that occur by birth or as a manifestation of some other disease in adults, the spinal deformity can be due to degenerative conditions, previous spinal surgery or even childhood deformities that have persisted.
