Primary bone tumors of the talus.

A review of 12 cases of bony tumors involving the talus is presented. Giant cell tumor was the most common tumor. Malignant tumors should be treated by surgical ablation followed by chemotherapy. There are good results after excision or curettage and bone grafting in the treatment of benign neoplasms. Giant cell tumors, if diagnosed early, can be treated by curettage and bone grafting, but if there is talar collapse, a talectomy can be performed.
