We present a case of an 8-year-old girl with a high grade osteogenic sarcoma of the proximal humerus treated with wide resection and vascularized proximal humerus treated with wide resection and vascularized proximal fibular epiphyseal transfer. At 5 years after reconstruction, the patient is tumor free and had a Musculoskeletal Tumor Score of 26/30 or 86.7%. The functional outcomes in terms of shoulder range of motion and pain were good. Complications include transient peroneal nerve palsy and mild valgus instability of the knee.

Osteosarcoma of the spine accounts for 1 to 3 percent of osteosarcoma. When this afflication of the spine occurs, it is often fraught with diagnostic dilemmas and treatment challenges.

OBJECTIVE: This manuscript reports on the cases reported over a 15- year period from the UP Musculoskeletal Tumor Unit. Only 2 of the 3 cases were available for review.

RESULTS: Both patients were initially misdiagnosed. This delay in diagnosis led to a delay in instituting appropriate chemotheraphy inevitable causing poor outcomes of treatment.

CONCLUSION: This report highlights the dilemma of treating a difficult site. Spinal osteosarcoma presents with numerous diagnostics and management obstacles. Unless clinician awareness is improved and these treatment options become available to patients, prognosis will not improve.
