oa Management of Giant cell tumor occupying the 5th metacarpal bone in 6 years old child

Giant cell tumor of the bone (GCTOB) is a relatively uncommon tumor of the bone. It is characterized by the presence of multinucleated giant cells. Giant-cell tumor of the bone accounts for 4-5% of primary bone tumors and ∼20% of benign bone tumors. Giant cell tumors of the hand are rare, accounting for only 2–4% of all giant cell tumors.

Giant cell tumor (GCT) of the bones of the hand has some special features as compared to GCT at other sites. Because of the aggressive nature of this lesion, adequate assessment of the treatment method is required.

The aim is to eradicate the disease but preserve as much hand function as possible. Methods of treatment include curettage with or without bone grafts, local resection possibly combined with reconstruction using homologous or autologous bone, amputation, and resection of one or more rays.
