A glass foreign body migrating into the lumbar spinal canal: a case report.

We report on a 12-year-old boy in whom a glass fragment migrated into the lumbar spinal canal causing low back pain and radiculopathy 6 years after injury. Computed tomography showed a foreign body in the anterior spinal canal of L5/S1. The patient underwent recapping T-saw laminoplasty to remove the foreign body. Scar formation was noted at the anterior dura. The glass fragment seemed to have penetrated into the intradural space from an anterior site. Postoperatively, the pain resolved immediately. At the 9-year follow-up, the alignment of the lumbar spine and healing of L5 was good, with no features of aseptic necrosis.
