混合现实技术在椎体成形治疗中的应用

BACKGROUND: How to improve the accuracy of puncture, reduce surgical damage, and improve surgical efficiency during vertebroplasty is currently one of the focuses of exploration and improvement in vertebroplasty techniques. OBJECTIVE: To explore the clinical significance of application of mixed reality technology in percutaneous vertebroplasty for spinal fractures. METHODS: Two patients with osteoporotic vertebral compression fracture in Dalian Second People’s Hospital in June 2023 were selected. Before operation, 128-row CT scanning of the lumbar spine was performed and the original data of digital imaging and communications in medicine (DICOM) were obtained. Visual Volume software was used to build the three-dimensional network model of vertebral compression fracture. Holographic imaging glasses were used to accurately map 3D network model images to the real world, assist the surgeon in completing preoperative simulation, explaining preoperative conditions and treatment plans, and guiding puncture and bone cement injection during surgery. RESULTS AND CONCLUSION: (1) Precise puncture was achieved with the assistance of a mixed reality technology. Postoperative imaging examination showed good bone cement filling and no obvious leakage. The postoperative symptoms of the patient were alleviated well, and they were able to move to the ground on the same day after surgery. (2) It is concluded that a mixed reality technology is helpful for preoperative surgical design and communication efficiency with patients and their families. Assisting with precise puncture during surgery, shortening surgical time, and reducing side injuries is a new and effective clinical diagnosis and treatment model, which has development potential in minimally invasive, precise, and personalized treatment of spinal surgery. © 2024, Publishing House of Chinese Journal of Tissue Engineering Research.
