Abstract

Objective To investigate the clinical efficacy and significance of a modified unilateral puncture percutaneous kyphoplasty (PKP) using personalized 3D-printed guides. Methods A retrospective analysis was performed on 110 patients with osteoporotic vertebral compression fractures (from June 2020 to June 2024). Based on the intraoperative use of a personalized 3D-printed guide, patients were divided into a 3D-printed guide group (n=55) and a traditional PKP group (n=55). The general information of the patients and perioperative parameters were compared between the two groups, including intraoperative bone cement leakage and dispersion patterns. Pain relief was evaluated using the Visual Analogue Scale (VAS) postoperatively. Results The 3D-printed guide group showed significantly shorter operative time, fewer fluoroscopies, less cement leakage, and better cement dispersion than the control group (all P<0.05). The postoperative VAS scores in both the 3D-printed guide group and control groups were significantly lower than the preoperative scores (P<0.05). All patients in both groups were followed up for at least 3 months. There was no significant difference in the incident of adjacent vertebral refracture. Conclusions The application of using personalized 3D-printed guides in a modified unilateral puncture percutaneous kyphoplasty significantly reduces surgical time and intraoperative fluoroscopy exposure compared to the conventional group, improves cement distribution, and lowers the cement leakage rate, making it a safe and effective approach.
