The tethered cord syndrome in adults with spina bifida occulta.

The management of adult-onset tethered cord syndrome (TCA) remains controversial, although the necessity of early surgery in children with TCS is well established. In this paper, we review the major publications that discuss the congenital tethered spinal cord (spina bifida occulta) presenting in adulthood. Data concerning acquired tethered cord from prior myelomeningocele repair were excluded. TCS in adults is an uncommon entity that can become symptomatic. The long-term surgical outcome after tethered cord release in this patient population is generally favorable, as most patients report improvement or stabilization of their symptoms. In addition, the overall post-operative complication rate is low. Although special consideration should be given to older patients with a poor general medical condition, it seems reasonable to recommend early surgical treatment in both symptomatic and asymptomatic adults.
