Abstract:
A 9-year-old girl with osteosarcoma of the radius was treated with segmental forearm resection and replantation followed by forearm lengthening of 11 cm. At 9-year follow-up, she had recovered sensory function, and her pinch and grasp were sufficient for performing daily activities. Functional outcomes evaluated by the Disabilities of the Arm, Shoulder, and Hand questionnaire and International Society of Limb Salvage functional score system were 4/100 and 23/30, respectively.
