摘　　要：[目的]探讨3D打印重建钢板联合后柱螺钉治疗髋臼四方区骨折的临床疗效。[方法]回顾性分析2019年1月—2022年1月本院采用3D打印设计辅助治疗的25例四方区髋臼骨折患者的资料,评价临床及影像结果。[结果] 25例患者手术时间平均(156.8±26.3) min,术中出血量平均(791.1±163.4) ml。所有患者均获随访,随访时间平均(21.1±6.9)个月。与术后1个月相比,术后3个月和末次随访时,患者Merled Aubigne-Postel评分[(10.6±1.9),(13.1±1.9),(17.0±1.6), P<0.001]、髋伸屈ROM [(84.8±13.1)°,(105.5±13.5)°,(127.0±12.1)°, P<0.001]、髋内-外旋ROM [(23.6±2.9)°,(39.6±3.1)°,(51.9±2.7)°, P<0.001]均显著增加。影像方面,术后Matta影像学评价无显著变化(P>0.05),末次随访时,骨折均愈合,愈合时间平均(13.7±1.4)周。[结论]基于3D打印设计的重建钢板联合后柱螺钉治疗髋臼四方区骨折可获得满意的临床疗效。[Objective]To investigate the clinical consequence of 3D printing design for reconstruction plate combined with posteriorcolumn lag screw in the treatment of acetabular quadrilateral plate fractures.[Methods]A retrospective study was done on 25 patients whohad acetabular quadrangular plate fractures fixed with reconstruction plate combined with posterior column lag screw based on 3D printingdesign in our hospital from January 2019 to January 2022.The documents regarding to clinical and imaging conditions were evaluated.[Re-sults]All the 25 patients had operation performed smoothly with the average operation time of(156.8±26.3)min and the average intraopera-tive blood loss of(791.1±163.4)ml,were followed up for an average of(21.1±6.9)months.As time went from the point 1 month after opera-tion,3 months postoperatively to the last follow-up,the Merled Aubign-Postel score[(10.6±1.9),(13.1±1.9),(17.0±1.6),P<0.001],hip flex-ion-extension range of motion(ROM)[(84.8±13.1)°,(105.5±13.5)°,(127.0±12.1)°,P<0.001],hip internal-external rotation ROM[(23.6±2.9)°,(39.6±3.1)°,(51.9±2.7)°,P<0.001]were significantly increased.As for imaging,there was no significant change in Matta grade at thelast follow-up compared with that immediately after operation(P>0.05).All patients had fractures healed,with healing time of(13.7±1.4)weeks on an average.[Conclusion]The 3D printed reconstruction plate combined with posterior column lag screw does achieve satisfactoryclinical outcomes for acetabular quadrilateral plate fractures.
