Abstract
The proposed normal function of the terminal filum of the spinal cord is to fixate, stabilize and buffer the distal cord from normal and abnormal cephalic and caudal traction. The filum is a viseoelastic band that usually allows the conus medullaris to move slightly during flexion and extension of the spine. It is theorized that if the viscoelasticity of the filum is lost or compromised by fatty infiltration [1] or abnormal thickening, then caudal tension and traction may cause stress upon the conus, resulting in a tethered spinal cord (TSC).
