Acetabular both-column fractures: Essentials of operative management

Biomechanical analysis of the acetabular buttress-plate: are complex acetabular fractures in the quadrilateral area stable after treatment with anterior construct plate-1/3 tube buttress plate fixation?

“…The bone in the quadrilateral area is thin, and the anatomical site is deep. The most difficult part of these bony deficits is that the screw can easily penetrate into the hip (1). Acetabular both-column fractures are the most common fracture in the quadrilateral area (1,2).…”

“…The most difficult part of these bony deficits is that the screw can easily penetrate into the hip (1). Acetabular both-column fractures are the most common fracture in the quadrilateral area (1,2). We often select a multi-approach (3) or modified ilioinguinal approach (1) to expose this fracture during the operation.…”

“…Acetabular both-column fractures are the most common fracture in the quadrilateral area (1,2). We often select a multi-approach (3) or modified ilioinguinal approach (1) to expose this fracture during the operation. Due to the presence of many postoperative complications, the reduction and internal fixation of acetabular both-column fractures though a single anterior approach has been a direction sought by many orthopedic doctors (4,5).…”

“…The lag screw through the anterior column to the posterior column would produce a certain clinical result (1,6), but its fixation is eccentric (partial posterior) and requires the fracture blocks of the anterior and posterior columns to not be crushed (6,7). The cerclage wires also produce some good results (8).…”

“…There are currently no biomechanical evaluations in the literature comparing buttress-plate for the treatment of complex acetabular fractures. Therefore, this study evaluated the biomechanics of a tube buttress-plate in both standing (1) and sitting (10) simulations.…”
