Correction to: Epidural Balloon Placement for Protection of the Spinal Canal During Cryoablation of Paraspinal Lesions.

In the published article the first sentence under the section heading Case Reports ("This study was conducted with the institutional review board approval and complied with the Health Insurance Portability and Accountability Act.") is incorrect. That sentence should be replaced with: "Case reports are exempt from IRB approval at the authors' institution. This study complied with the Health Insurance Portability and Accountability Act."
