AP and lateral X-ray views at 2-week postoperative visit show T10-L5 posterior segmental instrumentation with evidence of interbody fusion with cage at L2-L3. Evidence of prior fusion at L2-S1 noted. New laminectomy at L1-L2 with prior lumbar decompression noted distally.

Further imaging was obscured due to her extensive spinal instrumentation from prior surgeries (Figure 1).
Summary table of the patient's motor and sensory findings on electrodiagnostic examination and EMG waveforms, respectively. The above examination shows no response of left peroneal motor nerve, left radial sensory nerve, left superior peroneal sensory nerve, left sural sensory nerve, right sural sensory nerve, and left ulnar sensory nerve. There is reduced amplitude of right peroneal motor nerve. Evaluation of left peroneal and right peroneal F-wave showed no response, and left tibial F-wave showed prolonged latency (not pictured above). Left and right tibial H-reflexes were abnormal. EMG needle evaluation of the right anterior tibialis showed no polyphasic potentials and reduced recruitment. Left anterior tibialis showed no polyphasic potentials. Left iliopsias showed no polyphasic potentials and reduced recruitment.

Neurology was consulted, and postoperative nerve conduction testing and electromyography (EMG) were performed in order to further elucidate the cause of her symptoms (Figure 2).
