摘　　要：目的:分析CT数据髋部骨骼3D模型重建技术在髋关节置换术中的作用。方法:选定萍乡市人民医院骨关节外科2020年1月-2022年1月住院的80例髋关节置换术患者,以随机数字表法将其分为两组,每组40例,二维组手术前后采用传统二维影像评价,3D组手术前后采用基于CT数据髋部骨骼3D模型重建的三维影像评价,比较两组手术前后影像学测量指标[股骨近端匹配度、股骨偏心距、前倾角、外展角]、手术指标、术后髋关节功能优良率、并发症总发生率。结果:3D组术后6个月前倾角、外展角均低于二维组,差异均有统计学意义(P<0.05);3D组术后股骨近端匹配度、股骨偏心距均高于二维组,差异均有统计学意义(P<0.05)。3D组各项手术指标均优于二维组,差异均有统计学意义(P<0.05)。术后3个月,3D组髋关节功能优良率(95.00%)高于二维组(80.00%),差异有统计学意义(P<0.05)。术后1个月,3D组并发症总发生率(2.50%)低于二维组(20.00%),差异有统计学意义(P<0.05)。结论:髋关节置换术前后引入基于CT数据髋部骨骼3D模型重建技术,可有效改善髋关节功能,减少出血量、引流量,缩短手术及恢复时间,降低并发症发生率,提高手术安全性。Objective:To analyze the role of of CT data hip bone 3D model reconstruction in hip replacement.Method:A total of 80 patients with hip arthroplasty admitted to the Department of Bone and Joint Surgery of Pingxiang People's Hospital from January 2020 to January 2022 were selected and divided into two groups with 40 patients in each group by random number table method.The 2D group was evaluated by traditional 2D image before and after surgery,and the 3D group was evaluated by 3D image reconstruction of hip bone based on CT data before and after surgery.Imaging measurements(proximal femur matching degree,femoral offset,anteversion angle,abduction angle)before and after surgery,surgical indicators,excellent and good rate of postoperative hip function,and total incidence of complications were compared between the two groups.Result:Six months after surgery,anteversion angle and abduction angle of the 3D group were lower than those of the 2D group,the differences were statistically significant(P<0.05).The matching degree and femoral offset of proximal femur in the 3D group were higher than those in the 2D group,the differences were statistically significant(P<0.05).All surgical indexes in the 3D group were better than those in the 2D group,the differences were statistically significant(P<0.05).Three months after surgery,the excellent and good rate of hip joint function in 3D group(95.00%)was higher than that in 2D group(80.00%),the difference was statistically significant(P<0.05).One months after surgery,the total complication rate of the 3D group(2.50%)was lower than that of the 2D group(20.00%),the difference was statistically significant(P<0.05).Conclusion:The introduction of hip bone 3D model reconstruction technology based on CT data before and after hip replacement can effectively improve hip joint function,reduce blood loss and drainage volume,shorten operation and recovery time,reduce the incidence of complications,and improve surgical safety.
