Morbidity of graft harvesting versus bone marrow aspiration in cell regenerative therapy

Purpose

Using bone marrow mesenchymal stem cells (MSCs) with aspiration from the iliac crest is commonly used in reconstructive orthopaedic surgery. Because bone marrow aspiration is a percutaneous technique, the morbidity as compared with the classical bone graft should be decreased.

Method

Therefore in a retrospective review of 523 consecutive cases of bone marrow aspiration performed at the Henri Mondor Hospital from 1990 to 2006 for the treatment of fractures, minor and major complications were identified and compared to the number of complications observed during the same period with 435 classical iliac crest bone graft procedures performed for the same indications of treatment of fractures. Minor complications included superficial infections, superficial seromas, and minor haematomas. Major complications included herniation of abdominal contents through massive bone graft donor sites, vascular injuries, deep infections at the donor site, neurologic injuries, deep haematoma formation requiring surgical intervention or transfusion, and iliac wing fractures.

Result

Bone marrow aspiration decreased significantly the number of complications as compared with harvesting classical iliac crest bone graft that was associated with significant morbidity. Adverse events were significantly lower (p?Conclusion In our series the number of complications with bone marrow aspiration was ten times less than the complications observed with the classical technique of bone piece harvesting from the iliac crest, and the complications were clearly less severe.
