39-year-old male experienced in 1994 intense lower back pain after lifting weights, with spontaneous resolution. In 2006, he again experienced lower back pain radiating into both thighs. A lumbar MRI showed degenerative changes and EMG test showed L5 nerve root irritation. His physical examination demonstrated increased reflexes and a concern for cervical stenosis was entertained. Further cervical MRI and lumbar studies showed arthritic changes, and the thoracic MRI showed evidence of spinal cord compression. The surgeon suggested posterior thoracic laminectomy.
