The natural history of congenital rigid kyphosis, or gibbus deformity, is rapid progression in early childhood1-6. The apex of the deformity is most frequently located in the middle and upper lumbar spine3,7 and is associated with vertebral anomalies, a sharp apical angulation, and the potential for skin breakdown over the deformity. It is the most common type of kyphosis associated with myelomeningocele4.
