Abstract
In elderly acetabular fractures, central dislocation of the femoral head and impacted superior dome of the acetabulum is common. Unreduced dome impaction can lead to degenerative arthritis and results in poor results. Herein, we present a case of operative reduction and fixation performed via the modified Stoppa approach in acetabular fracture with superior dome impaction.

A 65-year-old man with acetabular factures. (A) Radiograph of right acetabular fracture involving both columns, with a medially displaced quadrilateral plate and superior dome impaction. (B) Coronal reconstruction computed tomography (CT) showing impacted fragment at the acetabular dome. (C) Sagittal reconstruction CT showing 2 pieces of impacted fragment. (D) Immediate postoperative pelvis anteroposterior image, showing a good reduction through the modified Stoppa approach. (E, F) Postoperative CT images, showing well-reduced dome impaction and congruent joint.
