Utility of Intraoperative Ultrasound (IOUS) Imaging in Spinal Surgery

Intraoperative ultrasound (IOUS) has emerged as a pivotal imaging modality in spinal surgery, providing continuous, real-time visualization that enhances both precision and safety in complex procedures. This technical note evaluates the efficacy of IOUS for lesion identification, surgical strategy guidance, and operative outcome assessment. Between 2021 and 2023, IOUS was integrated into 47 spinal surgeries at Nagoya University Hospital, including procedures for degenerative decompression, Chiari malformation decompression, syringomyelia shunting, and tumor resection.
