摘　　要：目的探讨基于MSCT三维扫描加重建对成人髋关节发育不良(DDH)患者行全髋关节置换术(THA)时髋臼假体的选择及截骨准确性的预测价值。方法选择60例行全髋关节置换术的成人DDH患者,其中使用常规术前规划的30例患者作为对照组,而使用MSCT三维扫描加重建技术的30例患者作为观察组,规划完成后依据规划情况实行手术操作及假体置入,收集两组手术前后相关信息,比较两组患者手术时间、术中出血量、术中透视时间、髋臼假体选择匹配率、股骨劈裂骨折发生率、骨盆及髋臼复位质量、Majeed评分及Harris髋关节功能评分,比较两组患者规划前及实际情况中截骨距离、尖肩距情况,评估MSCT三维扫描加重建技术与髋臼假体选择准确度的相关性。结果结果分析显示,观察组患者术前评估使用的MSCT三维扫描加重建技术与髋臼假体选择的准确性具相关性(P<0.05),且规划前情况与实际相比,观察组患者截骨距离及尖肩距的绝对误差更小(P<0.05),此外,相较于对照组患者,观察组患者的手术时间、术中出血量、术中透视时间及股骨劈裂骨折发生率明显更低,髋臼假体选择匹配率、术后3个月时的Majeed评分及Harris评分明显更高(P<0.05),骨盆及髋臼复位质量则两组比较差异无统计学意义(P>0.05)。结论基于MSCT三维扫描+重建对成人DDH全髋关节置换术中髋臼假体的选择及截骨的准确性具较高预测价值,且使用该技术进行术前规划对实际治疗效果及患者恢复具有显著优化效果。Objective To explore the effect of MSCT 3D scanning and reconstruction on developmental dysplasia of the hip(DDH)in adult patients with total hip arthroplasty,The predictive value of acetabular prosthesis selection and osteotomy accuracy in THA.Methods Selection in our hospital between February 2021 and February 2023 were 60 adult DDH patients underwent total hip replacement,which USES routine preoperative planning as a control group of 30 patients,and using MSCT+reconstruction of 3 d scanning technology as observation group of 30 patients,planning after the completion of the planning of the surgical operation and implant placement,Relevant information was collected before and after the operation of the two groups.Operation time,intraoperative blood loss,intraoperative fluoroscopy time,acetabular prosthesis selection and matching rate,femur split fracture rate,pelvis and acetabular reduction quality,Majeed score and Harris hip function score were compared between the two groups.The osteotomy distance and sharp shoulder distance of the two groups were compared before planning and in actual conditions,and the correlation between MSCT 3D scanning and reconstruction technology and the accuracy of acetabular prosthesis selection was evaluated.Results Results analysis showed that MSCT 3D scanning+reconstruc⁃tion technology used in preoperative evaluation of patients in the observation group was correlated with the accuracy of acetabular prosthesis selection(P<0.05),and the absolute errors of osteotomy distance and sharp shoulder distance of patients in the observation group were smaller than the actual situation before planning(P<0.05).In addition,compared with the control group,the operative time,intraoperative blood loss,intraoperative fluoroscopy time and incidence of femoral split fracture in the observation group were significantly lower,and the matching rate of acetabular prosthesis selection,the Majeed scores and Harris scores were significantly higher in the following 3 months were significantly higher(P<0.05
