Successful Cementless Cup Reimplantation Using Cortical Bone Graft Augmentation after an Acetabular Fracture and Cup Displacement

Objective

To report repair of a periprosthetic acetabular fracture with concurrent component displacement after cementless total hip arthroplasty (THA). Study Design

Clinical case report. Animals

Dog (n=1) with an acetabular fracture after THA. Methods

Acetabular repair was performed on a highly comminuted periprosthetic acetabular fracture after cementless THA. A bulk, structural corticocancellous autograft from the ipsilateral ilial wing was used for repair and reconstruction of the dorsal acetabular wall before reimplantation of a cementless acetabular component. Results

Repair of a periprosthetic acetabular fracture with a bulk structural autograft was successful in reconstruction of the dorsal acetabular wall and in reestablishing a stable, functional cementless THA acetabular prosthesis. Conclusions

Structural corticocancellous autografts from the ilium can be successfully used in repair of periprosthetic acetabular fractures after THA. Clinical Relevance

Structural corticocancellous grafting from the ilium can be considered as a treatment option for repair of periprosthetic acetabular fractures after THA.
