摘　　要：[目的]评价3D打印半骨盆重建骨盆的安全性及早期临床疗效。[方法]回顾性分析2022年1月—2023年4月本科收治的12例骨盆肿瘤患者的临床资料,评价围手术期情况及短期随访结果。[结果]12例患者均顺利完成手术,手术时间平均(339.3±97.1)min,术中出血量平均(956.3±708.8)ml,术中输注悬浮红细胞量平均(4.5±3.0)u,术中输注新鲜冰冻血浆平均(412.5±359.4)ml。随访时间平均(7.2±4.0)个月。1例患者术后7个月因肿瘤进展死亡,1例术后1年发生假体脱位,经手术进行复位。与术前相比,末次随访时,疼痛VAS评分[(3.3±0.5),(2.0±0.7),P=0.014]显著减少,髋关节Harris评分[(46.7±5.4),(64.8±7.3),P=0.003]、MSTS评分[(11.0±4.8),(16.3±2.9),P<0.001]显著增加。[结论]通过3D打印半骨盆重建可有效减轻患者疼痛,功能较术前恢复,是一种安全有效的重建方法。[Objective]To evaluate the safety and early clinical efficacy of 3D printed semi-pelvis reconstruction for defect secondary to tumor resection.[Methods]A retrospective study was done on 12 patients who received semi-pelvis reconstruction with 3D printed pros⁃theses for pelvic tumor in our department from January 2022 to April 2023.The documents regarding to perioperative conditions and shortterm follow-up results were evaluated.[Results]All the 12 patients were successfully operated,with an average operation time of(339.3±97.1)min,intraoperative blood loss of(956.3±708.8)ml,the intraoperative suspended red blood cell infusion of(4.5±3.0)units,and intraop⁃erative plasma infusion of(412.5±359.4)ml.All of them were followed up for(7.2±4.0)months on an average,1 patient died 7 months after surgery due to tumor progression,and 1 patient suffered dislocation 1 year after surgery and underwent surgical reduction.Compared with those preoperatively,pain VAS score significantly decreased at the last follow-up[(3.3±0.5),(2.0±0.7),P=0.014],whereas the Harris hip score[(46.7±5.4),(64.8±7.3),P=0.003],the MSTS score[(11.0±4.8),(16.3±2.9),P<0.001]significantly increased.[Conclusion]The semipelvis reconstruction with 3D printed prostheses does effectively reduce the pain,and improve the function postoperatively,which is a safe and effective reconstruction method.
