Reconstruction of forearm support with ulnar translocation after resection of chondrosarcoma in the proximal radius Introduction Chondrosarcoma is a malignant bone tumor characterized by tumor cells that produce tumorous cartilage [1]. Chondrosarcomas occurring in the radius are usually found in the distal segment and the bone defect after surgery is usually reconstructed using an autologous fibula graft [2, 3]. Chondrosarcoma occurring in the proximal radius is rare. A patient with chondrosarcoma in the proximal radius was treated and the skeleton of the forearm was reconstructed by translocation of vascularized ulna after extensive resection of the proximal radius.
Material and methods General information A 36-year-old man was admitted to hospital complaining of pain in the right forearm for 21 months that had been exacerbated for 2 months. Previous X-rays taken at the local hospital showed osteolytic and expansive bony destruction in the proximal radius.
Physical examination and laboratory examination
palpated; it was firm and poorly circumscribed, with tenderness and percussive pain. There were no other positive signs, except the axion angle of the elbow joint was 110°. Routine blood tests, biochemistry, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and procalcitonin (PCT) results were normal. Tumor markers including prostatespecific antigen (PSA), CA19-9, CA12-5, and AFP results were normal.
Imaging examinations The X-ray image showed swelling and bony destruction in the proximal and middle radius, almost all of the radius was involved, and the radiologist thought that infectious lesions could not be excluded. A computed tomography (CT) scan with reconstruction showed a wide range of thickened radial cortical bone, osteolysis and typical central calcifications. The MRI showed an expansive proximal radius with a wide range of abnormal signals in the medullary canal; the surrounding periosteum was edematous and thickened, and the soft tissue adjacent to the radius was swollen. Bone scan showed a concentration of nuclides in the proximal radius, which were considered neoplastic lesions (. Fig. 1).
The right forearm was swollen, especially in the anterolateral area. A mass of approximately 3 cm × 4 cm could be
Preoperative pathological examination

A CT-guided percutaneous biopsy of the lesion was performed for a pathologic di-
agnosis. Pink colored cartilage-like cells were observed by microscopy; there was extreme pleomorphism with markedly hyperchromatic nuclei, bizarre tumor giant cells and small cells, and frequent mitotic figures. The pathological diagnosis was chondrosarcoma (grade III).
