CT三维重建在成人髋关节发育不良髋臼形态研究中的进展

Research progress on application of three-dimensional CT in acetabular morphology of developmental dysplasia of hip in adults

目的 对CT三维重建（3DR）在成人髋关节发育不良（DDH）髋臼形态研究的优势、测量参数、髋臼分型进行综述。方法 近年DDH髋臼形态研究中以“髋臼形态”、“成人DDH”、“THR”及“CT3D重建”为关键词，在PuMed和中国知网数据库中检索近年发表的相关文献，对CT3DR的应用优势、测量参数、髋臼分型进行分析总结。结果 髋关节是一个复杂的3D立体结构，DDH髋臼形态可发生严重的病理改变。术前应用CT3DR技术可以全面认识DDH髋臼形态，从而可优化术前设计，提高手术精确度，降低术后并发症。结论 CT3DR能全面显示髋关节的立体形态和各部位解剖结构的空间关系，对于DDH的诊断、分型，术前全面认识髋臼形态，提高髋关节置换准确度及减少术后并发症都发挥着重要的作用。

Objective To summarize the advantages, measurement parameters and acetabular classification of the CT three-dimensional reconstruction （CT 3DR） in the acetabular morphology of developmental dysplasia of hip （DDH） in adults. Methods To search and consult all the literatures arailable by the key words of the acebular morphology, DDH in adults, THR and CT 3DR in the database of Pub Med and CNKI To analyze and summarize the advantages, measurement parameters and acetabular classification of the acetabular morphology of DDH in adults by referring to recent relevant database. Results Hip joints are complicated three-dimensional structures. Serious pathological changes can take place in the acetabular morphology of DDH in adults. Preoperative application of CT 3DR can recognize the acetabular morphology of DDH in adults comprehensively, which can optimize the preoperative design, improve the operation accuracy and reduce the postoperative complications. Conclusions CT 3DR displays the morphology and anatomical structure of spatial relations of the hip joint comprehensively and accurately. It plays an important role not only in the diagnosis and classification of DDH in adults, but also in the improvement of operation accuracy and reduction of postoperative complications.
