Fig 1 A 58-year-old woman with 9 months of pain in her lower back radiating to her left foot through the back of her leg without neurologic loss. Magnetic resonance imaging revealed disk herniation at L5-S1 with apex deviated to the left causing minor impingement of the S1 nerve root. Electromyography suggested an S1 radiculopathy. After conservative options failed, a combined L5 and S1 transforaminal ESI using the procedure described improved symptoms more than 75% at 3 months. (A) The oblique view with and without highlights of the Scotty dog formation. (B) Simultaneous placement of needles in L5 and S1 foramen in oblique view with and without highlights of the Scotty dog formation. (C) The lateral view. (D) The AP view. (E) The AP view with contrast.
