Congenital kyphosis.

Congenital kyphosis is a rare spinal deformity, and many physicians are unfamiliar with its proper treatment. Following a case report, this article presents a brief synopsis of the literature. We present the case history of a 45-year-old woman with a congenital kyphosis of 140 degrees who has been followed at our institution for 39 years. No treatment was ever prescribed, affording the unique opportunity to study the natural history of this entity in a particular patient.
