Distal Tibia Sarcoma Treatment Using Allograft Arthrodesis of the Ankle

Study Overview
=================
Brief Summary
-----------------
The study show the clinical results of limb salvage for primary malignant bone tumor of the distal tibia using block excision of the tumor and reconstruction with allograft arthrodesis with different methods of fixation (plates or intramedullary nail system)

Detailed Description
-----------------
It is well known that before the 1980's the usual treatment for the sarcomas of the distal tibia was amputation (1). Currently, however, after the improvement of the chemotherapy treatments, potential reconstructions of the area in well studied patients are possible, and for that we have a wide range: auto graft, allograft and prosthetic reconstructions (2, 3) Is important to know that osteosarcoma still meant the principal diagnosis, followed by the Ewing sarcoma and synovial sarcoma, but their malignant potency is lower than when they are present in the rest of the body (4, 5, and 6) The purpose of this study is to recollect the patients' data followed from different institutions and countries that have the criteria for their inclusion in the study (primary malignant bone tumor of the distal tibia that underwent block excision of the tumor and reconstruction with allograft arthrodesis from the patient management for any of the multidisciplinary sarcoma team including in this study).
