Bone Marrow Clot for Posterior Lumbar Fusion

Bone marrow aspirate (BMA) in association to graft substitutes has long been introduced as a promising alternative to iliac crest bone graft in spinal fusion. However, BMA use is limited by the absence of a standardized technique, of a physical texture and by the possibility of dispersion away from the implant site. Recently, the potential use of a new formulation of BMA, named BMA clot, has been preclinically described. A prospective pilot clinical study designed to assessing the safety and efficacy of autologous vertebral BMA (vBMA) clot as multifunctional bio-scaffold in instrumental posterior lumbar fusion will be performed.
