ABSTRACT

Introduction: Chondrosarcoma is a malignant tumor of chondroid matrix-producing cells; based on its frequency, it is the second most common malignant bone tumor (10-20%) and responds poorly to chemo- and radiotherapy. It is infrequent in the pelvis. It has a rapid growth potential. The indicated treatment is broad resection with tumor-free margins. Pelvic reconstruction after resection is controversial. The current management of musculoskeletal neoplasias has a two-fold purpose. First of all, controlling the neoplasia by means of surgeries with cancer-free margins and, second, performing procedures for the reconstruction of the involved segment achieving limb preservation with maximum functionality. Objective: Intrapelvic reconstruction with the proximal third of the ipsilateral femur in a patient with a chondrosarcoma in Enneking-Dunham’s zone II. And placement of an unconventional femur prosthesis. Clinical case: We present herein the case of a 58 year-old male, with a lytic lesion of the right acetabulum. The patient completed the diagnostic protocol, and the biopsy result was dedifferentiated chondrosarcoma. Conclusion: The purpose of the surgical technique is to use the proximal third of the femur as a novel reconstruction alternative with massive autograft for tumor lesions located in Enneking-Dunham zone II.
