Abstract
PURPOSE: 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. METHODS: A retrospective evaluation of all patients with intraarticular periacetabular metastases who underwent the procedure outlined. RESULTS: 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. DISCUSSION: 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.
