Abstract
Revision femoral arthroplasty can be a daunting task. Historical success with a host of different reconstructive options has previously been reported. The Zimmer Modular Revision (ZMR®) system provides a complete armamentarium for the revision setting. For lesser femoral defects, the modular ZMR system can be used to create a custom preassembled implant. For more difficult situations, the implant can be sequentially assembled in vivo. The ZMR system can thus separate the tasks of revision femoral surgery so that the surgeon does not have to manage all issues at once. Fixation, length, offset, and implant version can all be handled independently to allow a safe, easy, and reproducible reconstruction in all settings.
