＜news＞ On October 2nd (Friday) and 3rd (Saturday), the 27th Annual Meeting of the Japanese Society of Spinal and Spinal Nerve Techniques (Kameda General Hospital, President of Dr. Kubota) will be held remotely. From 2:20 PM on Saturday, October 3rd, a mini lecture 1 FEM session titled "Vertebral bone analysis by 4DQCT method" will be held at the 3rd venue. RATOC Nango will report. Among them, we will introduce simulation of 4DQCT and posterior invasion correction surgery for scoliosis. Using preoperative images, vertebral body rotation was corrected by simulation, screws and implants were fixed to the vertebral body, stress simulation was performed by compressive load, and preoperative and postoperative intraosseous stress distributions were compared. We provide reference information for procedures
