 A 25-year-old man presented with radicular pain of the left leg. Pain did not improve after conservative therapy for 9 months. Old fracture of the superior articular process of the L4 vertebra was suspected on a computed tomography. And block for the lt. L4 nerve root was effective. These results suggested that his symptom was caused by the nonunion fragment compressing lt. L4 nerve root. Microendoscopic surgery was applied to this case, and the fragment was removed safely. After surgery he has resumed his former occupation without pain. Microendoscopic surgery minimizes resection of the posterior elements of the spine, and prevents postoperative instability. In this case, microendoscopic decompression seems to decrease risk of delayed spinal instability.
