Characteristic Analysis and Surgical Exploration for Acetabular Roof Fractures: Multicenter Retrospective Cohort Study (CASEARF)

Acetabular roof was a crucial structure for maintaining the stability of hip joint; however, its important role was not especially emphasized in the Letournel-Judet classification system. Acetabular roof was segmented into the roof column and roof wall in Three-column classification and fracture in this area alone was defined as A3 injury. Radiographic data and functional outcome of A3 injury patients were reviewed to explore the characteristics and surgical strategy.
