Retroperitoneal Approach for Excision of Wear-Debris Pseudotumor: A Case Report

Pelvic pseudotumors may occur as a reaction to wear-debris after hip arthroplasty and are rarely treated with surgery. We describe an instance in which a pelvic pseudotumor along the iliopsoas muscle tendon sheath was debulked using a retroperitoneal approach in a patient presenting for treatment of a prosthetic hip infection. The patient recovered uneventfully and was ambulatory with a new hip prosthesis at 3 months after procedure.

Retroperitoneal exposure provided safe, excellent exposure to a wear-debris pelvic pseudotumor in this case.
