The in situ rib split graft.
The in situ rib split graft was devised in response to experimental data demonstrating superior survival of autograft bone bearing periosteum.  A more compelling reason for adopting the technique as a standard means for obtaining limited amounts of rib graft is the marked decrease in pain and pulmonary morbidity postoperatively.  This is achieved by leaving the inner half of the rib in continuity and resecting only the outer half as the graft.
