The spinal cord ends in the lower back (around L1 or L2), but the lower spinal nerve roots continue, forming a bundle that resembles a horse’s tail (called the cauda equina). The record produced is known as a myelogram. Confidently interpreting spine imaging studies is an essential skill for neurologists as many spinal cord disorders can produce significant disability if not diagnosed and treated correctly. Their emphasis is on making you as independent as possible. But researchers are continually working on new treatments, including stem-cell therapies, innovative electrical stimulation, bionic exoskeletons and new medications.
