Microendoscopic Surgical Treatment for Lumbar Disc Herniation with Conjoined Nerve Roots : A Case Report

Abstract

We report a case of lumbar disc herniation with conjoined nerve roots treated with microendoscopic discecotomy. A 27-year-old man complained of lower back pain with sciatica in his left leg. Physical examination showed hypesthesia in the right leg without muscle weakness or atrophy. Lumbar myelography, CTM and MRI revealed a space-occupying mass which might have been caused by a herniated disc at the L5/S1 level on the right side. He underwent microendoscopic discectomy. Operative findings showed entrapment of the S1 root conjoined with the L5 root. Axillary discectomy was required because the nerve roots had lost mobility. The symptoms were completely relieved after surgery.
