How to create by your own a customized hip cement mega-spacer for a hip megaprosthesis two-stage revision surgery after oncologic limb-salvage surgery - Surgical technique and case report.

ABSTRACT

Managing chronic periprosthetic infections in patients who have undergone limb-salvage surgery following a malignant bone tumor with megaprosthesis often involves a two-stage revision surgery with the use of a cement-spacer. This paper show details the preparation of a self-made intramedullary metal-stabilized mega-cement spacer for patients needing a two-stage revision surgery due to infection after oncologic bone tumor resection and limb-salvage surgery with megaprosthesis and present two clinical cases treated with this technique. The report provides a practical surgical technique to create a cement hip mega-spacer using readily available tools in most orthopedic surgical settings.
