Abstract

The mixed reality (MR) technique has recently been widely used in the orthopedic surgery with satisfactory results reported. However, few studies have focused on the application of MR in the Lumbar fracture (LF). In this retrospective study, our aim is to analyze some findings by investigating the feasibility of MR applied to lumbar fracture treatment. Posterior vertebrectomy has been operated on 7 patients. The MR–based intraoperative three-dimensional image-guided navigation system (MITINS) was used to assist implantation of pedicle screws. The feasibility and safety of pedicle screw implantation were assessed by postsurgery radiography. The visual analog scale (VAS) and Oswestry Disability Index (ODI) were used to assess the pain level and recovery situation before and after surgery. 57 pedicle screws were safely and precisely placed into three-dimensional lumbar models by using MITINS. No screw was found outside the pedicle of the models, and it was not necessary for the X-ray to provide extra locative information during the operation with the use of MITINS. In summary, the application of MITINS is feasible, safe, and accurate while the lumbar fracture surgery is processing, providing satisfactory assistance for spine surgeons.

Highlights

With aging of the population, the incidence of osteoporosis has increased significantly [1]
As vertebral degeneration and anatomical variation are very common in the elderly people, the additional problems associated with implanting pedicle screws during an operation are becoming more noteworthy [4]
Our aim was to evaluate a new surgical navigation system based on the mixed reality (MR) approach and MR–based intraoperative three-dimensional image-guided navigation system (MITINS) while inserting pedicle screws into the elderly patients, which can assess its safety and accuracy during the treatment of lumbar fracture

Summary

Introduction

With aging of the population, the incidence of osteoporosis has increased significantly [1]. Fractures associated with osteoporosis have become a challenging problem in elderly people. Lumbar fracture is the commonest form of the senile osteoporosis fracture [2]. During the treatment of lumbar fracture, if the fracture is only slightly compressed, conservative treatment or vertebral plasty is usually sufficient. If the fracture is severely compressed, or if the type of fracture is burst fracture, open surgery is required [3]. As vertebral degeneration and anatomical variation are very common in the elderly people, the additional problems associated with implanting pedicle screws during an operation are becoming more noteworthy [4]
