ABSTRACT

Introduction: radical resection is the surgical treatment of choice in musculoskeletal malignancies, which often settle in the pelvis and lower limbs. Megaprothesis reconstruction has been imposed in recent years as the gold standard in limb preservation surgery. Material and methods: descriptive retrospective study series of cases, including 30 patients operated between 2011 and 2019 of musculoskeletal pelvic and lower limb tumors at our institution that underwent limb-sparing reconstruction with the megaprosthesis. Functional results according to the MSTS (Musculoskeletal Tumor Society) index and complication rate were analyzed. Results: the average follow-up was 40.8 months (12-101.7). Nine patients (30%) underwent pelvic resections and reconstructions, 11 patients (36.7%) underwent hip reconstruction with megaprothesis due to femoral involvement, in three patients (10%) complete femur resection was performed, and seven patients (23.3%) underwent prosthetic reconstruction of the knee. The mean MSTS score was 72.5% (range: 40-95%), and the complication rate was 56.7% (17 patients), being de tumoral recurrence (29%) the main complication. Conclusion: tumor megaprothesis give satisfying functional results, allowing the patients to realize a relatively normal life after a lower limb-sparing surgery.
