To the Editor: In his Editorial on the Spine Patient Outcomes Research Trial (SPORT),1 which compared operative vs nonoperative treatment for lumbar disk herniation, Dr Flum2 criticized the authors for not including a sham surgery group in the trial. He correctly stated that sham controls are important in determining efficacy of interventions that have subjective outcomes. However, he incorrectly characterized the nature of a sham intervention in the SPORT trial as being an ethical alternative.
