Conjoined Nerve Root Anomaly Associated with Lumbar Disc Herniation: A Case Report

ABSTRACT

The condition of anomalous nerve root is rare. The authors are reporting a case of conjoined nerve root anomaly associated with lumbar disc herniation in a 36-year-old male who was transferred from another hospital. A standard hemilaminectomy with a discectomy had been performed under the disgnosis of the L4-5 lumbar disc herniation at the other hospital. However symptoms were not relieved. During a second surgery at our hospital, a L5-S1 conjoined nerve root was discovered after removal of the extradural hematoma at the previous laminectomy site, a medial facetctomy with a foraminotomy were carried out and the conjoined root was decompressed completely. The patient returned to work 2 months postoperatively with complete relief of symptoms.
