(A) A 51-year-old female had proximal humeral fracture from a slip down injury. Possible diagnosis was simple bone cyst, enchondroma, giant cell tumor or aneurismal bone cyst.
(B) She was treated with closed reduction and intramedullary nailing.
(C) After the surgical treatment, biopsy of fracture site was confirmed as giant cell tumor. One week after the primary operation, curettage and autoiliac bone graft were performed (Black arrow is an autologous iliac bone block).
(D) The bone union was gained at 13 months after operation.

(A) A 55-year-old male, with humerus shaft fracture from car accident 3 years ago, initially had an internal fixation, but a follow-up bone graft was carried out due to the continuous mal-union.
(B) After his third operation with preoperative evaluation of lung mass, biopsy of fracture site was confirmed as pathologic fracture originated from lung cancer (White arrow is a lung mass).
(C) At 5 months after closed reduction and IM nailing with bone graft, we found persistent non-union of humeral shaft. He died at 26 weeks after operation.
