Abstract: A method of treating spinal cord injuries in a patient using sagittal MR images of the spinal cord injury to guide the extent of exposure of the neuro/orthopedic surgeon during a posterior spinal fusion for the purpose of autologous stem cell therapy in the setting of spinal injury; the method using large volumes of the patient's bone marrow aspirated to yield a large quantity of heterogeneous autologous stem cell concentrate containing cellular and subcellular fractions, in addition to soluble protein factors (defined as heterogeneous concentrate) exhibiting regenerative potential which is then applied directly over the spinal cord (under the dura/arachnoid) in the areas affected.
