Total Hip Arthroplasty With Impacted Bone Graft on Acetabulum for Osteoporotic Acetabular Fractures: A Report of 3 Cases.

Osteoporotic acetabular fractures in elderly patients have recently been increasing, but the best treatment remains uncertain due to the difficulty in stabilizing these fractures with osteosynthesis. We performed total hip arthroplasty with an impacted bone graft on the acetabula of 3 elderly patients with comminuted acetabular fractures after confirming acetabular callus formation via radiographic imaging 2 months following the patients' initial injuries. Two of the patients presented in the subacute phase after conservative treatment, and 1 patient had no history of trauma or quadrilateral surface destruction. Two patients achieved good functional results at the 3-year follow-up. Furthermore, no loosening of the prosthesis components or subsidence of the acetabular cemented cup was evident on radiographic imaging in any of the patients.
