Lateral Interbody Fusion (DLIF/XLIF)
Lateral, or transpsoas lumbar, interbody fusion is similar to transforaminal lumbar interbody fusion, but is performed using incisions on the patient's side. Dr. Tumialán generally prefers this incision technique when he is fusing vertebrae that are located in the upper part of the lumbar spine. As with transforaminal lumbar fusion, transpsoas lumbar fusion can stabilize two or more vertebrae for reduced pain and restored function.
