<unk>  cord syndrome (TCS) refers to a group of neurological disorders that relate to malformations of the<unk>  cord. Various forms include tight filum terminale, lipomeningomyelocele, split cord malformations (diastematomyelia), dermal sinus tracts, and dermoids. All forms involve the pulling of the<unk>  cord at the base of the<unk>  canal, literally a<unk>  cord. The<unk>  cord normally hangs loose in the canal, free to move up and down with growth, and with bending and stretching. A<unk>  cord, however, is held taut at the end or at some point in the<unk>  canal. In children, a<unk>  cord can force the<unk>  cord to stretch as they grow. In adults the<unk>  cord stretches in the course of normal activity, usually leading to progressive<unk>  cord damage if untreated. TCS is often associated with the closure of a<unk> bifida. It can be congenital, such as in tight filum terminale, or the result of injury later in life.
