Bone Marrow Injection

Harvesting autologous bone grafts can be associated with considerable morbidity [28]. Because bone marrow incorporates the osteoinductive properties of bone grafting (0.01% of marrow cells are osteogenic stromal stem cells), experimental studies have provided evidence that local autologous bone marrow injections can stimulate nonunions to heal [3, 29]. The technique is simple: marrow is obtained from the iliac wing and directly injected into the nonunion site, which should be stabilized by cast bracing or by osteosynthesis.
