Good functional outcome evaluation of free vascularized fibular head graft (FVFHG) as treatment after resection of giant cell tumor (GCT) campanacci 3 at proximal humerus: A case report.

INTRODUCTION: Giant cell tumor (GCT) is benign aggressive tumors with a high rate of recurrence and capacity to metastasize. Wide resection is the treatment of choice, but this creates a flaw at the proximal end of the humerus. There are various methods exist as the treatment option to fixed this problem.

PRESENTATION OF CASE: We here present our experience on wide resection and free vascularized autogenous fibula head grafting for GCT at the proximal humerus of a 32 years old male. We performed free vascularized fibular head graft (FVFHG) as a reconstruction method followed by sling procedure and used the long head of biceps tendon. Evaluation of anatomical, functional, and radiological outcomes of this management was performed. After 3 years, the patient has a good outcome.

DISCUSSION: Free vascularized fibula graft is the most favored as a treatment after resection of a tumor on the proximal humerus. The advantages are can be harvested without many difficulties and rapid healing. In our case, we used a free vascularized fibular head graft (FVFHG) for proximal humerus reconstruction after resection giant cell tumor (GCT) on the right proximal humerus. We use the peroneal artery as vascular pedicle due to well vascularity to the peripheral part of fibula. There is no fibula head reabsorption after three years post-operation.

CONCLUSION: FVFHG for reconstruction modality as the treatment after resection of GCT grade Campanacci 3 on proximal humerus shows satisfactory result following long term evaluation.
