Osteosarcoma of Radial Diaphysis: A Pediatric Case Report

Abstract

Osteosarcoma is the most common primary malignant bone tumor
in children. It can affect all bones but has a predilection for the
metaphyses of the long bones and appears in the knee in most
cases.Osteosarcoma is rare in the forearm and the radius of her
ri
ght arm. We report the case of a 13
-
year
-
old girl with
osteosarcoma of the middle third of the radius. A thoraco
-
abdominopelvic scanner and bone scintigraphy were performed
as part of the extension work
-up and did not indicate metastasis.
Following neoadju
vant chemotherapy, surgery consisted ofan
oncological resection of the tumor with the removal of more than
two-thirds of the proximal radius, followed by an ulnarization of
the forearm six months after the failure of distal radioulnar
arthrodesis. After su
rgery, the patient received adjuvant
chemotherapy.The clinical and functional outcomes were
satisfactory at the five-year follow-up evaluation
