The aim of this study was to investigate the efficacy of three-dimensional (3D) printing-assisted treatment for acetabular fractures (AFs) and to compare with conventional surgical methods.
Between May 2019 and May 2022, a total of 44 patients (33 males, 11 females; mean age: 40.6±11.8 years; range, 20 to 68 years) who were diagnosed with AFs based on clinical symptoms, X-ray and computed tomography (CT) and underwent open reduction and internal fixation in Hospital of Xinjiang Production and Construction Corps were retrospectively analyzed. The patients were divided into two groups based on whether 3D printing was applied as the experimental group (n=24) and control group (n=20). In the experimental group, pelvic and acetabular data were imported into a 3D printer, and an equal-scale highly simulated model was printed using photosensitive resin as the 3D printing material. The model was used to develop more specific personalized surgical plans, to determine the optimal sequence of surgical procedures for fracture reduction, and simulate surgery in vitro.
In the experimental group, the mean surgical duration was shorter (123.57±22.05 vs. 163.57±26.20 min, p<0.001), the mean intraoperative bleeding loss was lower (557.14±174.15 vs. 885.71±203.27 mL, p<0.001), and the frequency of intraoperative fluoroscopy was lower (8.64±1.65 vs. 12.07±2.76, p<0.001) than in the control group. No statistically significant differences were found between the two groups in the Visual Analog Scale scores after surgery or the hip function score after treatment (p>0.05). No major postoperative complications were observed in any of the patients.
Compared to conventional surgical treatment, preoperative 3D printing-assisted treatment for adult patients with AFs can significantly reduce surgical duration, intraoperative bleeding loss and frequency of intraoperative C-arm fluoroscopy, reducing surgical difficulty and improving surgical safety.
本研究旨在探讨三维（3D）打印辅助治疗髋臼骨折（AFs）的疗效，并与传统手术方法进行比较。
2019 年 5 月至 2022 年 5 月，根据临床症状、X 线和计算机断层扫描（CT）诊断为 AFs 并在新疆生产建设兵团医院接受切开复位内固定的 44 例患者（男 33 例，女 11 例；平均年龄 40.6±11.8 岁；范围 20 至 68 岁）进行回顾性分析。根据是否应用 3D 打印将患者分为实验组（n=24）和对照组（n=20）。在实验组中，将骨盆和髋臼数据导入 3D 打印机，使用光敏树脂作为 3D 打印材料打印出等比例的高度模拟模型。该模型用于制定更具体的个性化手术计划，确定骨折复位的最佳手术程序顺序，并进行体外模拟手术。
实验组的手术时间更短（123.57±22.05 分钟 vs. 163.57±26.20 分钟，p<0.001），术中出血量更少（557.14±174.15 毫升 vs. 885.71±203.27 毫升，p<0.001），术中 C 臂透视次数更少（8.64±1.65 次 vs. 12.07±2.76 次，p<0.001）。两组患者术后视觉模拟量表评分或治疗后髋关节功能评分无统计学差异（p>0.05）。所有患者均未出现重大术后并发症。
与传统手术治疗相比，术前 3D 打印辅助治疗成人 AFs 可显著缩短手术时间、减少术中出血量和术中 C 臂透视次数，降低手术难度，提高手术安全性。
