Hi there. Conus medullaris is the terminal end of the spinal cord. It occurs near lumbar vertebral levels one and 2. The nerve roots at the ends are called cauda equine. The terminal nerve root tail is the filum terminale. Conus medullaris syndrome and cauda equine syndrome are complex neurological disorders manifesting as back pain, unilateral or bilateral leg pain, paresthesias and weakness, perineum or saddle anesthesia, rectal and urinary incontinence. Hope this helps. Consult a neurologist for a detailed clinical evaluation if relevant. Take care.
Conus medullaris syndrome has symptons like low back pain, numbness and weakness on legs, foot and groin. There are other symptons like impotence, difficult walking and loss of bladder control.
