Autogenous cancellous bone graft from the proximal tibial metaphysis

ABSTRACT

Many graft materials are available for surgical treatment of maxillofacial bony defect and deformity. Despite concerted efforts to gain comparable outcomes with allogenic bone, xenogenic bone, bone substitutes, and alloplasts, the results related to function, from and adaptibility remain superior with autogenous bone. The cancellous bone is relatively more osteogenic than cortical bone. The superior osteogenic properties of cancellous bone has been widely used an oral and maxillofacial surgery. Well-recognized donor sites of cancellous bone have included ilium, rib and calvarial bone, But the procurement of cancellous bone from any site should be no considered biologic insult to the patients. The proximal tibia as an alternative donor site has the potential to yield viable cancellous bone with a minimum of morbidity. We experienced several jaw defect treated with autogenous proximal tibial cancellous bone grafting. The harvested cancellous bone was soft and easily molded to fill defects and the recipient site showed a favorable result. Moreover, with uneventful healing process, the donor site showed the overall lack of morbidity. This report presents clinical applications of the autogenous cancellous bone graft from the proximal tibial metaphysis and satisfactory results to repair of the jaw defect.
