ABSTRACT

Pseudotumor is a rare complication that can occur following hip arthroplasty. This complication may present with pain, swelling, and decreased function and may lead to bone and soft-tissue destruction. We report a case of pseudotumor formation resulting from corrosion of a modular neck in a hip replacement with a ceramic-on-polyethylene bearing. The patient underwent successful revision surgery using an extended trochanteric osteotomy, removal of the entire stem, and implantation of a new femoral stem and ceramic-polyethylene bearing without a modular neck.
