Brown-Sequard syndrome due to penetrating injury by an iron fence point

Study design: Case report. Objectives: To present an unusual type of penetrating objects causing Brown-Sequard syndrome (BSS) and its clinical character. Setting: Department of Orthopaedic Surgery, Shanghai Changzheng Hospital, Second Military Medical University, Shanghai, PR China. Methods: A 54-year-old man fell from a height of 4 m onto an iron fence, and a sharp iron fence point penetrated the right side of his back. He developed left-sided BSS. Both X-ray film and computed tomography scanning of the thoracic spine showed a right vertebral plate of Th5 fracture and metal fragments inclining through the posterior and left lateral of the spinal canal. Emergency decompressive laminectomy and removal of the foreign metal piece were performed. No improvement in neurological function was observed 10 days after surgery, and thus hyperbaric oxygen treatment was initiated twice a day for the next 1 month. Results: Forty days after surgery, his bladder function returned to normal. The motor deficit had regressed and he could walk without assistance 70 days after the operation. One year later, his lower extremity functions recovered almost completely, except for slight numbness on the right side. Conclusion: As far as we know, on the basis of existing literature, the injury mechanism to BSS by a sharp iron fence point has not been reported so far. The satisfactory recovery after injury may in part be attributed to timely surgery and continuing hyperbaric oxygen treatment.
