图1 术前病人大体照。图A示术前拄拐跛行步态;图B示双下肢不等长
图2 术前左侧髋关节正侧位X线片和髋关节CT,可见左侧股骨颈完全破损,严重骨缺损。图A为骨盆正位X线图像;图B为左髋侧围X线片;图C~D为双侧髋关节CT图像
图3 术前左侧髋关节CT图像3D重建,可见左股骨颈完全破损,股骨近端骨质破坏
图4 术前3D规划,模拟缺损、设计和打印个性化假体。图A为三维重建左髋关节,设计髋臼截骨导板;图B为三维重建左髋关节髋臼部分,设计个性化髋臼假体及截骨导板;图C为设计好的个性化髋臼假体及股骨柄假体
图5 术中假体安装及术后切口愈合情况。图A示术中在截骨导板引导下精准截骨、安装髋关节假体;图B术中左侧髋关节假体安装完成,假体位置良好;图C左侧髋关节术区切口愈合良好,引流管通畅
图7 左髋关节置换术后6个月左侧髋关节正侧位X线片,示左侧髋关节假体位置良好,假体无松动、下沉及骨溶解,无感染,髋臼侧可见骨长入
