Abstract

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.
