The quadrilateral plate (QP) is an essential structure of the inner wall of the acetabulum, an important weight-bearing joint of the human body, which is often involved in acetabular fractures. The operative exposure, reduction and fixation of QP fractures have always been the difficulties in orthopedics due to the special morphological structure and anatomical features of the QP. Fortunately, there have been many effective methods and instruments developed for QP exposure, reduction and fixation by virtue of the combined efforts of numerous orthopedists. At the same time, each method presents with its own advantages and disadvantages, resulting in different prognoses. It is necessary to have a thorough understanding of the anatomy, radiology and fixation techniques of the QP in terms of patient prognosis optimization. In this paper, the anatomical features, definition and classification of QP, operative approach selection, implant internal fixation methods and efficacy were reviewed.
四边形板（QP）是人体重要负重关节髋臼内壁的一个重要结构，髋臼骨折时该结构常受累。由于QP特殊的形态结构和解剖特点，QP骨折的手术显露、复位及固定一直是骨科领域的难题。幸运的是，众多骨科医生共同努力，已经研发出许多用于QP显露、复位及固定的有效方法和器械。同时，每种方法都有其优缺点，导致预后不同。为优化患者预后，有必要深入了解QP的解剖、影像学及固定技术。本文对QP的解剖特点、定义及分类、手术入路选择、植入物内固定方法及疗效进行了综述。
