Application of three-Dimensional Printed Acetabular Model to the Treatment of Severe Acetabular Bone Defect in Cup Revision Surgery: A Technical Case Report

The application of three-dimensional (3D) printed acetabular model made by personal 3D printer to cup revision surgery has some advantages such as preoperative evaluation, shorting operation time and easier creation of fitted bulk allograft in the cases with a massive bone defect which would need a structural bulk allograft along with the Kerboull-type acetabular reinforcement device. We presented a cup revision case with severe acetabular bone defect treated by the surgical technique for the intraoperative simulation using 3D printed acetabular model to create the fitted structural bulk allograft. There were no obvious complications such as post-operative infection associated with 3D printed models although the patient was observed for a short term period. This technique using 3D printed model has the great advantages, which would be a useful option for cup revision surgery with massive defect of the acetabulum.
