Abstract
- We present a case of postoperative radiculopathy caused by extrusion of centering pin marker in lumbar artificial disc treated by percutaneous endoscopic procedure. A 39-year-old man was presented with intermittent electric shock like left leg pain along S1 dermatome. He received lumbar total disc replacement (TDR) on L5-S1 for his degenerative disc disease (DDD) six years before the revisit to the clinic. X-ray and CT revealed extruded pin from the core of the implant compressing the thecal sac and left S1 root. The position and mobility of the implant were seen intact in follow-up X-rays. The marker pin was removed by percutaneous endoscopic interlaminar technique. The patient’s preoperative leg pain was completely resolved after the procedure.
