Primary bone healing involves intra-membraneous ossification while secondary bone healing involves endochondral ossification. Fracture healing involves a complex and sequential set of events to restore the bone , in which stem cells play a crucial role. (Aiyer, no date) . Bone defects present a therapeutic challenge to both the surgeon as well as to the patient. When not treated properly, patients can have long-lasting symptoms such as non-unions, pseudoarthrosis and large bone defects. Such patients are left untreated due to the absence of further facilities to enhance bone growth and fracture healing. Tissue engineering with stem cell auto grafts have proven to be the gold standard for fracture healing and therefore is used by surgeons to treat bone defects and large-bone fractures. B...
