Comparison of anterior and posterior iliac crest bone grafts in terms of harvest-site morbidity and functional outcomes

Previous studies indicate a high complication rate when harvesting bone graft from the iliac crest. This study demonstrated lower complications when harvesting posteriorly. Major/minor complications in this study were 8%/15% anterior and 2%/0% posterior.

Natural history of posterior iliac crest bone graft donation for spinal surgery: a prospective analysis of morbidity

A study was performed to evaluate bone graft donor site morbidity in patients undergoing spinal fusion surgery. Donor site pain is the major component of morbidity. The highest pain scores in this study were reported at 6 months post surgery.

Prospective evaluation of chronic pain associated with posterior autologous iliac crest bone graft harvest and its effect on postoperative outcome

Iliac crest bone graft is the gold standard for spinal fusion, but complications include chronic pain, numbness and poor cosmesis at the graft harvest site. This study looked at 170 patients undergoing spinal fusion surgery. Chronic harvest site pain and discomfort was reported in a significant percentage of patients more than 3 years post surgery.

Harvesting of cancellous bone from the proximal tibia under local anesthesia: donor site morbidity and patient experience

Autologous cancellous bone graft is frequently used in maxillofacial surgery. A study was conducted of patients who had bone graft removed from the proximal tibia under local anesthetic for use in the maxillofacial reconstruction.

 Stem cells in bone grafting: Trinity allograft with stem cells and collagen/bet tricalcium phosphate with concentrated bone marrow aspirate

Bone grafting is needed for fracture healing and fusion of the foot and ankle. Allograft bone combined with concentrated bone marrow aspirate is an alternative to harvesting autologous bone graft.

Mesenchymal stem cells

The mesenchymal stem cell (MSC) is the progenitor cell for skeletal tissues including cartilage, bone, tendon and ligaments. Understanding the role of MSCs in tissue repair/regeneration suggests the importance of these stem cells in future cell therapy treatments for a variety of diseases/conditions.
