Abstract
Intraoperative ultrasonography (IOUS) is a noninvasive and simple tool to assess the real-time anatomic data of the spinal cord during a surgical procedure. The normal anatomical landmarks and pathological lesions can be obtained accurately through IOUS images that can help to shorten the duration of surgical procedures and improve surgical results. In cases of ossification of the posterior longitudinal ligament (OPLL), the relationship between OPLL and the spinal cord can be easily visualized using IOUS. It is important to confirm an echo-free space between OPLL and the ventral side of the spinal cord to achieve adequate decompression. If IOUS shows no echo-free space on the ventral side of the spinal cord from OPLL, additional procedures to decompress the spinal cord would be required. This chapter describes the suitable application of IOUS for OPLL surgery.
