【目的】探讨切开复位重建钢板内固定治疗移位髋臼骨折的疗效。【方法】回顾性分析52例有移位的髋臼骨折患者的临床资料,分析手术入路,观察疗效。【结果】52例患者髂腹股沟入路21例,Kocher-Langenbeck(K-L)入路26例,前后联合入路5例,均采用重建钢板内固定治疗。按照 Matta 影像学评价标准,解剖复位29例,满意复位18例,不满意复位5例；根据美国骨科学会(AAOS)髋关节功能评价标准：优32例,良13例,可5例,差2例,优良率为86.5%(45/52)。【结论】采用重建钢板内固定治疗移位髋臼骨折,能有效固定骨折、重建关节的稳定性,是治疗髋臼骨折的良好方法。“,”Objective]To discuss the clinical effects of displaced acetabular fracture treated by the open re-duction reconstructive plate internal fixation.[Methods]The clinical data of 52 patients with displaced acetabu-lar fractures and surgical approach were retrospectively analyzed to observe the curative effect.[Results]Of 52 cases of patients ,21 of them were treated with groin approach,26 cases with Kocher-Langenbeck (K-L),5 cases with front and back combined approach,and all of them with reconstruction plate internal fixation.Ac-cording to Matta imaging evaluation criteria,29 cases were anatomic reduction,18 cases were satisfactory,5 cases were not satisfied;According to hip function evaluation standard of the American orthopaedic society (AAOS):32 cases were excellent,13 cases were good,5 cases were fair,2 cases were poor,the excellent and good rate was 86.5% (45/52 ).[Conclusion]Reconstruction of acetabular fractures with reconstruction plate internal fixation can effectively fix fracture and reconstruct the stability of the joint,and it is a good method for the treatment of acetabular fractures.
