He presented the next day with intractable back and leg pain. Magnetic resonance imaging revealed ventral displacement of the cauda equina and a subdural collection on the right L3\/L4 nerve roots. Revision decompression revealed occult durotomy caudal and contralateral to the index decompression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Minimally invasive spine (MIS) surgery leverages shorter operative time and reduced postoperative pain.
