The orthopedic foot and ankle surgeon needs bone grafts in the clinical situation of fracture healing and in bone-fusion procedures. This article briefly outlines thought processes and techniques for 2 recent options for the surgeon. The Trinity product is a unique combination of allograft bone and allograft stem cells. The beta-tricalcium phosphate and collagen materials provide an excellent scaffold for bone growth; when combined with concentrated bone marrow aspirate, they also offer osteoconductive and osteoinductive as well as osteogenerative sources for new bone formation.
