Male patient, 15 years old, left proximal humeral osteosarcoma. He received segmental resection of left proximal humerus. The resection length accounted for 71.4% of total humeral length and the residual length was 8 cm. Plate-prosthesis composite (PPC) was used for reconstruction. (A) Preoperative X-ray and magnetic resonance imaging. (B) PPC was used for reconstruction and a synthetic mesh was used for soft-tissue reconstruction. (C) Postoperative X-ray. (E) X-ray on 14 months after surgery showed no evidence of mechanical prosthetic complications.
