Safety of a Noninvasive Expandable Electromagnetic Prosthesis with an In Situ Ventricular Assist Device: A Case Report.

Expandable prostheses allow limb length maintenance in skeletally immature patients who undergo limb salvage. Chemotherapy for osteosarcoma involves anthracyclines with a dose-dependent side effect of cardiotoxicity. Patients can be successfully and safely lengthened with expandable electromagnetic prostheses with in situ ventricular assist devices.
