Conus Medullaris Syndrome
Conus medullaris syndrome is caused by injury to the conus medullaris and lumbar nerve roots. It is a subset of the Incomplete Cord Syndromes. Injury to T12-L2 are the most likely to cause the syndrome. The conus medullaris is in close proximity to the nerve roots. The clinical features include severe back pain, and a combination of upper and lower motor neurone deficits. This is unlike Cauda Equina Syndrome which only has lower motor neurone deficits. There may be other symptoms similar to cauda equina syndrome such as saddle anaesthesia, bladder dysfunction, bowel dysfunction, and lower limbs radicular pain and/or radiculopathy.
