[Salvage surgery treatment in osteosarcoma of the fibula with seventeen years survival].

INTRODUCTION
Osteosarcoma is the most frequent primary bony tumor with two picks of incidence, one around the 15 years (adolescents) and another in old people.


CLINICAL CASE
Patient of 14 years with pain clinic in proximal fibula. It was diagnosed by radiological studies and biopsy of located osteosarcoma with infiltration of cortical and periostium and extension toward fibula epiphysis. After preoperatory chemotherapy she was carried out tumoral resection with margins of 5 cm. following approaches of Enneking (surgery of salvation of the member). Several cycles of chemotherapy were completed after surgery. The patient, after seventeen years, is free of illness.


DISCUSSION
Traditionally in the treatment of the located osteosarcoma you proceeded to the radical amputation for norm. At the moment due to the advances of the surgical and diagnostic techniques (able to detect precociously the local and distant dissemination of the tumor) it is possible to make other therapeutic modalities that preserve the member until in 90% of the patients. Thanks to the use of the chemotherapy the rate of survival nowadays approaches to 70% in those cases diagnosed previously to the metastasis appearance. At the moment in those cases in which the illness is located, the tumoral size is reduced and have a good answer to the preoperatroy chemotherapy, it is more advisable to opt for a surgery of salvation of the limb making a wise resection at distance of the margins of the tumor and accompanying it of cycles of combined chemotherapy.
