TO THE READERSHIP: An error appeared in the article by Vargas et al. (Vargas E, Shabani S, Mummaneni PV, et al. Does surgery for metastatic spinal tumors improve functional outcomes in patients without spinal cord compression but with potentially unstable spines?J Neurosurg Spine. Published online May 5, 2023. doi:10.3171/2023.3.SPINE221120).

Because of a miscommunication during production of the article, the Spine Instability Neoplastic Score (SINS) was inadvertently removed from the title. As the scores indicate the specific patient group under consideration in our study, they have been included in the corrected title, which appears below.

Does surgery for metastatic spinal tumors improve functional outcomes in patients without spinal cord compression but with potentially unstable spines (SINS 7–12)?

The article has been corrected online as of June 16, 2023.
