In daily practice, when CT or MRI does not show a pathological lesion in a patient with persistent abnormal neurological signs, it is important to obtain imaging studies of the spine in dynamic position.

Neurological Analysis Based on the Terminal End of the Spinal Cord and the Narrowest Level of Injured Spine in Thoracolumbar Spinal Injuries.

Article Synopsis
- This study investigated neurological variations in patients with epiconus, conus medullaris, and cauda equina syndromes after acute thoracolumbar spinal injuries.
- It involved 87 patients who were categorized based on the location of the narrowest part of their spinal canal, identifying 22 with epiconus, 37 with conus medullaris, and 25 with cauda equina involvement.
- Although more patients initially had a narrowed epiconus, by the end of the study, neurological recovery was similar across all three syndromes, highlighting the importance of anatomical classification in understanding these conditions.

Objective This study aimed to analyze the neurological symptoms caused by thoracolumbar lesions according to their distance from where the spinal cord terminates for a better description of epiconus syndrome. Methods We retrospectively reviewed cases of patients with neurological symptoms caused by a thoracolumbar lesion in a single institute. Neurological symptoms were analyzed according to the distance from the proximal end of the lesion to where the spinal cord terminates using MRI or CT myelograms.

The most caudal part of the spinal cord shows special anatomical characteristics and it contains epiconus (L4-S2 segments), the conus medullaris (S3-S5 segments), and surrounding nerve roots. Lesions of the thoracolumbar junction cause epiconus or conus syndrome. Epiconus syndrome is characterized by segmental muscular weakness and atrophy of one or both lower extremities, often accompanied by foot drop.

The motor deficits, urogenital dysfunction and perineal numbness of the conus medullaris syndrome are well known. Less well known is the disease of the epiconus, the spinal cord immediately above the conus medullaris. The disease is quite unique with ankle plantar-flexion weakness that usually exceeds ankle dorsi-flexion weakness.
