<unk>  is a rare neurological disorder (occurring in 0.05 to 0.25 of 1000 births) caused by tissue attachments that limit the movement of the spinal<unk>  within the spinal column. These attachments cause an abnormal stretching of the spinal<unk> . The course of the disorder is progressive. Symptoms may include lesions, hairy patches, dimples, or fatty tumours on the lower back; foot and spinal deformities; weakness in the legs; low back pain; scoliosis; and incontinence.<unk>  may go undiagnosed until adulthood, when sensory and motor problems and loss of bowel and bladder control emerge. This delayed presentation of symptoms is related to the degree of strain placed on the spinal<unk>  over time.<unk>  appears to be the result of improper growth of the neural tube during fetal development, and is closely linked to spina bifida. Tethering may also develop after spinal<unk>  injury and scar tissue can block the flow of fluids around the spinal<unk> . Fluid pressure may cause cysts to form in the spinal<unk> , a condition called syringomyelia. This can lead to additional loss of movement or feeling, or the onset of pain or autonomic symptoms.
