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.
Keywords: Oncology; Osseous fixation pathways; Periacetabular metastases; Total hip arthroplasty.
