Spondylolisthesis,image 1 of 2. Coloured magnetic resonance imaging (MRI) scan of a side view of the lower back of a 46 year old woman showing spondylolisthesis. This is the backward displacement of a vertebra (spinal bone,light purple) relative to the one above it. Here it is between the lumbar vertebrae L4 (centre left) and L5 (lower centre). The condition is often due to a hereditary bone disorder,but can also be caused by trauma. It typically causes back pain,and the displaced vertebra puts pressure on the nearby spinal cord,causing sciatica (leg pain),loss of bladder and/or bowel control and eventually paralysis of the lower limbs. For the same patient after five years,see image M330/1432 | |
