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.

Advanced hip arthrosis in young patients presents a unique problem. The goal is to provide a stable and pain-free hip joint for early return to function. Several surgical options are available, most of which however present with unpredictable results. Arthrodesis as a bone conserving procedure addresses pain relief and offers the pursuit of an active lifestyle, making it a suitable option for young, active individuals with high physical demands. We reviewed the cases of three pediatric patients with end stage hip arthrosis secondary to non-traumatic and non- septic etiologies managed by hip arthrodesis. After a mean follow up of 17 months, fusion was noted in all subjects at an average of 4 months. All subjects have become pain free as of last follow up although there was expectedly some degree of functional limitation, and an asymmetric and slightly slower gait compared to normal. Most importantly, all patients have returned to an active lifestyle both at school and at play.
