Procedure for Spinal Instrumentation
Spinal fusion is a process using bone graft to cause two opposing bony surfaces to grow together. In medical terminology, this is called arthrodesis. Bone graft can be taken from the patient (termed autologous or allograft bone) during the primary surgical procedure or harvested from other individuals (termed allograft bone). Another option for some patients undergoing lumbar (low back) spine surgery is bone morphogenetic protein (BMP). BMP stimulates new bone to grow.
