Autologous bone marrow concentrate combined with platelet-rich plasma enhance bone allograft potential to induce spinal fusion
Vol 30, Issue 4S1, 2016
Abstract
Bone marrow cells concentrate (BMCs) is a source of osteoprogenitor cells and platelet-rich plasma (PRP) is a source of growth factors. The objective of the study was to determine whether BMC and PRP could increase the potential of bone allograft to induce posterolateral-lumbar spinal fusion compared to the bone allograft alone. A prospective nonrandomized radiographic study has been conduced on 10 patients with posterolateral instrumented fusion for degenerative lumbar disease with 1-year follow-up using CT scan. A fresh frozen bone allograft alone and bone allograft with a mixture of autologous BMC and PRP blended with thrombin were apposed in the right and left posterolateral side, respectively. CT showed good right fusion masses (allograft alone) in 4 patients and poor in 6; good left masses (BMC and PRP plus allograft) in 9 patients and poor in 1. The differences detected between right-side and left-side masses show an advantage in adding BMC and PRP to the bone allograft to increase spinal fusion rate.
