Case: We outline the management of a 10-month-old girl with an Ewing sarcoma involving the entire radius. The patient was treated with neoadjuvant chemotherapy resulting in almost a complete response. A limb-sparing procedure was performed consisting of a radical resection of the entire radius and centralization of the carpus to the ulna.
Conclusion: This case is the first to describe an Ewing sarcoma of the entire radius in a 10-month-old girl treated with a radical resection of the radius and centralization of the carpus on the ulna. Over 2 years postoperatively, the construct remains stable with a very good functional and aesthetic outcome.
