Bone Marrow Concentrate Enriched in Platelet Growth Factors Combined With De-mineralized Bone Matrix for Complex Revision and Complex Lower Limb Arthrodesis
Authored by Edgardo R Rodriguez
Complex arthrodesis procedures in the lower limb present a challenging
model for successful outcomes, especially in the face of multiple
co-morbidities [1]. Not only is this patient population at risk for
delayed union and nonunion, the potential for infection and delay in
soft
tissue healing is also of great concern [2]. Autolo-gous fusion
solutions have been used for decades in bone repair procedures in the
form of
bone grafts (iliac or rib) or bone marrow (Figure 2) aspirate harvested
from the marrow cavities with good results. Bone graft harvest comes
with inherent challenges, often resulting in do-nor site morbidity [3].
Bone marrow aspirate (BMA) har-vested from the marrow cavities is a
mixture of stromal and peripheral blood and has less inherent risk and
still provides a potent osteogenic stimulus. Unfortunately, pure BMA
has relatively few osteoprogenitor cells per volume and contains a high
proportion of red blood cells that can interfere with bone healing [4].
