The Spine: Congenital and Developmental Conditions

Abstract

The chapter initially discusses normal spinal development and variants. Pathology is addressed fi rst in terms of general structural vertebral anomalies. These are then applied to congenital scoliosis, kyphosis, and lordosis, as well as anomalies involving the craniovertebral junction. Discussion of spinal dysraphism follows, including tethered fi lum terminale, hydrosyringomyelia, and diastematomyelia. Congenital intraspinal tumors are briefl y reviewed. Klippel-Feil syndrome and caudal regression are presented, as well as spine manifestations of neurofi bromatosis and several other syndromes. Idiopathic scoliosis is discussed in detail, including curve measurement, imaging techniques, and treatment options. Neuromuscular scoliosis is briefl y reviewed. The chapter concludes with juvenile kyphosis.
