- Abstract: 【Objective】 To investigate the clinical efficacy and significance of percutaneous cement discoplasty (PCD) in treating elderly patients with spinal instability and vacuum phenomenon on imaging. 【Methods】 We retrospectively analyzed 27 patients with spinal instability and vacuum phenomenon on imaging who underwent PVABC between June 2019 and September 2022. We recorded the surgery duration, bone cement usage, intraoperative bleeding, and total hospitalization time. We evaluated the improvement in pain and lumbar function by comparing pre- and postoperative visual analog scale (VAS) scores, Oswestry Disability Index (ODI) scores, and lumbar Japanese Orthopedic Association (JOA) scores. We also compared the change in intervertebral height and the distribution rate of bone cement in the intervertebral space by pre- and postoperative imaging data. 【Results】 All the 27 patients who underwent PCD had effective follow-up. The mean hospitalization time was (4.2±1.85) days, and the mean surgery duration was (32.3±4.51), (53.6±12.17), (74.4±6.33), and (90.0±10.36) minutes for single-, double-, triple-, and quadruple-level procedures, respectively. The intraoperative bleeding volume ranged from 2 to 13 mL, which was significantly lower than that of traditional intervertebral fusion surgery. Postoperative VAS pain scores, ODI scores, and JOA scores were significantly improved compared to those before surgery. In terms of imaging, the intervertebral height of the patients improved after surgery, and the distribution of bone cement in the intervertebral space was relatively good in the operated segments. Mechanical stability of the spine was restored. 【Conclusion】 For patients who are not suitable for open surgery due to severe complications, PCD is a feasible treatment option.
