Sacral sparing is a spinal cord injury phenomenon in which some or all function remains intact below the injury site at the sacral spine level. The sacrum is a triangle-shaped 5-segment bone located at the lower spine between the lumbar region and the tailbone. Incomplete spinal cord injuries to the sacral spine are often referred to as sacral sparkings. When a sparing occurs, it means that the spinal cord is partially compressed but not entirely severed, leaving some of the motor functions intact.
