Reinforced reconstruction: A technique for the treatment of periacetabular metastases.

Abstract

To describe a single-stage reconstruction of intraarticular periacetabular metastases that utilizes a cemented acetabular liner reinforced with percutaneous screws oriented along various osseous fixation pathways. A retrospective evaluation of all patients with intraarticular periacetabular metastases who underwent the procedure outlined. 16 procedures (1 bilateral) were included. There were no intraoperative complications or postoperative mechanical failures to date despite allowing the patients to immediately weight bear in the postoperative setting. Utilizing osseous fixation pathways to reinforce a cemented acetabular cup represents a safe and effective strategy to allow for immediate weightbearing in patients with periacetabular metastases.
