Case report 592: Bone graft donor site of tibia.

A case is presented in which a donor site for a bone graft from the proximal end of the tibia caused diagnostic difficulty. The bony defect produced in such procedures is easily confused with a variety of neoplastic and neoplasm-like lesions. The clinical history, use of immediate postoperative films, and knowledge concerning the common sites for obtaining bone graft donor tissue are critical in offering the correct diagnosis.
