Abstract
There is an increasing interest in uses of bone marrow aspirate concentrate for various orthopedic procedures throughout the lower extremity. The ideal location of bone marrow harvest for lower extremity surgery would be near the surgical field, however, there has not been a quantitative comparison of the contents of bone marrow concentrate retrieved from various locations in the lower extremity. The objective of this present study is to assess the contents of bone aspirate concentration obtained from various harvest sites (anterior iliac crest, proximal tibia, and calcaneus), as determined by cell surface markers for osteoprogenitor cells and colony forming unit assays to evaluate differences in growth and differentiation ability.
