目的:探讨X线检查对不同类型髋臼骨缺损的诊断价值。方法:成人骨盆尸体标本6具,按照美国骨科协会(AAOS)髋臼骨缺损分型法制作不同部位的节段型和腔隙型缺损模型。分别进行包括前后位、髂骨位和闭孔位X线检查。结果:即使综合3个不同投照位的X片,尚不能显示所有类型的骨缺损。结论:对全髋置换术后髋臼骨缺损必须进行3个不同投照位的摄片。所有病例应该接受CT扫描检查,才能对所有骨缺损类型进行准确评估,为手术提供翔实的参考。
Objective: To investigate the diagnostic value of X-ray in different types of acetabular bone defects. Methods: Six adult cadaveric cadavers were used to make segmental and lacunar defect models of different sites according to the American Academy of Orthopedic Associations (AAOS) acetabular bone defect classification method. Respectively, including anteroposterior position, iliac bone and closed-cell X-ray examination. Results: Even though three radiographs of different radiographs were combined, all types of bone defects were not yet displayed. CONCLUSION: Three different radiographs must be taken for acetabular bone defects after total hip arthroplasty. All cases should be undergone CT scan examination, in order to accurately evaluate all types of bone defects, provide detailed information for surgery.
