The healing potential in cauda equina syndrome secondary to traumatic posterior L5-S1 dislocation. A case report with 16 years follow-up.

Cauda equina syndrome is the result of any lesion that compresses or paralyzes cauda equina roots which are both motor and sensory. It is an uncommon syndrome, which features low back pain, sciatica, variable lower extremity motor and sensory loss with possible bladder and bowel dysfunction. It is an emergency situation as it may cause significant morbidity such as permanent paralysis, impaired bladder and/or bowel control or loss of sexual sensation. We present the case of a patient who was admitted to the emergency department with a traumatic posterior L5-S1 dislocation, low back pain and bladder dysfunction 8 days following an initial trauma. Open L5-S1 reduction and posterior stabilization was performed and the dural sac was decompressed. Most of the patient's neurological deficits resolved over several years, following the initial surgery.
