Brief summary (from the registry)
The main objective of this prospective study is to compare the clinical outcomes after lumbar fusion for chronic low back pain using the four techniques commonly employed in our surgical practice. Lumbar fusion stops motion at a painful vertebral segment, which can decrease back pain. The four techniques are standard transforaminal lumbar interbody fusion (S TLIF), minimally invasive transforaminal lumbar interbody fusion (MI TLIF), extreme lateral interbody fusion (XLIF), and axial lumbar interbody fusion (AxiaLIF). Each differ in where incisions are made and level of invasiveness; not all may be implemented in each surgical case. The four different techniques are all standard approaches with different advantages and have yet to be compared in efficacy for relieving chronic low back pain.
