Abstract
Objective
In this study, we introduced a design of a targeted puncture trajectory applied to unilateral extrapedicular percutaneous vertebroplasty.
Methods
62 individuals with osteoporotic vertebral compression fractures (OVCF) were included in this research at the Tongling People’s Hospital, from January 2019 to December 2020. Percutaneous Vertebroplasty (PVP) was performed on all patients using a targeted unilateral extrapedicular puncture technique guided by G-arm fluoroscopy. The operating time, volume and dispersion of bone cement, and cement leak were all evaluated. The oswestry disability index(ODI) and the visual analog scale (VAS) were used to assess pain relief and quality of life (QOL).
Results
The targeted puncture trajectory for unilateral extrapedicular PVP was used to successfully treat a total of 62 fractured vertebrae without any apparent clinical issues. In comparison to their equivalent preoperative values, the VAS and ODI values after surgery were considerably lower (P < 0.01). The bone cement not only could be across the midline of the targeted vertebrae but also appeared in both the bilateral pedicle and the center projection region on the anteroposterior X-ray film, according to radiologic results in all injured vertebrae. There were 3 cases of leakage at the anterior border of the vertebral body and 2 cases of leakage into the intervertebral region without significant clinical manifestations. Furthermore, no bone cement leaked into the vessels or spinal canal.
Conclusion
The design of the targeted puncture trajectory used in unilateral extrapedicular PVP not only ensures that the bone cement injector transcends the midline of the vertebral body, but it also improves the accuracy of the injector arriving at the contralateral pedicle projection area. As a result, this approach can increase well-distributed bone cement diffusion while preventing cement leakage into the spinal canal.
