In situ splitting of a rib graft for reconstruction of the orbital floor.

A technique of in situ split rib graft harvest is described. It has been used in bone graft reconstructions of the orbital floor when small, thin, malleable grafts are desired. The advantages of in situ rib harvest are technical simplicity, diminished risks of known rib harvest-associated complications, and avoidance of the risks involved with in situ split cranial bone harvesting.
