title: Osteochondroma of the Radial Tuberosity in Child.
abstract: Osteochondromas are common benign bone tumors. They may occur on any bone preformed in cartilage, but usually are found on the metaphysis of a long bone near the physis. In this article, we report a case of the subluxation of the radial head caused by osteochondroma on the radial tuberosity. A 9-year-old female patient presented with a hard palpable mass and pain in her posterior aspect of left elbow joint. Preoperative radiography and MRI demonstrated an expansile bone lesion arising in the left radial tuberosity of the proximal radius. Resection of the bone tumor was done without any complications. Biopsy confirmed the diagnosis of osteochondroma without malignant degeneration. A one year after surgery, the elbow had full range of motion without any discomfort and complication.
