Reconstruction of acetabular posterior wall fractures with extension to the roof using dual arc-shaped plates: A case report.

Anatomical reduction and rigid fixation of acetabular posterior wall fractures extending to the acetabular roof proves challenging because of the big bony fragment and muscular obstruction to accessing this region. This report describes a novel reconstructive technique in a patient with an acetabular posterior wall fracture involving the acetabular roof. Both the standard Kocher-Langenbeck approach and a greater trochanter osteotomy technique were used. Following anatomical reduction, a dual arc-shaped reconstruction plate technique was employed to achieve rigid fixation. The patient recovered with satisfactory function at the injured hip. We recommend this dual arc-shaped reconstruction plate technique for the treatment of acetabular posterior wall fractures extending to the acetabular roof in clinical practice.
