We’ve had many discussions about the technical aspects of vertebroplasty and kyphoplasty on BackTable MSK. However, in this episode, we take a deeper look into the history of these procedures, exploring early research controversies and the challenges that threatened their existence. Our host, Dr. Jacob Fleming, is joined in the BackTable Studio by interventional neuroradiologist Dr. Joshua Hirsch, who was in San Diego for the ASSR 2025 meeting. Dr. Hirsch is the Chief of the Interventional Spine Service at Massachusetts General Hospital.

SYNPOSIS
Dr. Hirsch begins by outlining the historical origins of radiologists using cement injection and how this practice evolved into vertebroplasty. He then highlights early research on the procedure, focusing on key 2009 NEJM papers that sparked both scientific and public controversy, leading to setbacks in research and disparities in access to life-changing care. Since that time, newer studies have demonstrated the clear benefits of spinal augmentation for patients with vertebral insufficiency fractures, including Dr. Hirsch’s own research showing a mortality benefit compared to nonsurgical treatment. Overall, the doctors discuss how far this field has advanced and the exciting developments currently in progress.
