Transforaminal Lumbar Interbody Fusion (TLIF)

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Spinal Fusion Techniques

Background:

• Posterior Lumbar Interbody Fusion (PLIF) historically used direct posterior approaches.
• Transforaminal Lumbar Interbody Fusion (TLIF) evolved to utilize a lateral access window, reducing dural retraction.
• TLIF theoretically offers enhanced fusion rates, foraminal decompression, deformity correction, and discogenic pain relief.

Purpose of the Study:

• To detail the procedural steps and considerations for Transforaminal Lumbar Interbody Fusion (TLIF).
• To highlight the technical nuances and advantages of the TLIF approach.
• To provide a systematic overview of TLIF for spinal fusion.

Main Methods:

• Standard posterior midline incision for spinal access.
• Pedicle screw placement followed by laminectomy and facetectomy for decompression.
• Disc space preparation via a lateral window, employing distraction techniques and specialized instruments for cage insertion and bone grafting.

Main Results:

• The described TLIF technique facilitates access to the interbody space with reduced dural tension.
• Thorough disc space preparation and appropriate cage selection are critical for fusion success and deformity correction.
• Postoperative recovery is comparable to other standard fusion procedures, with fusion expected within 6-12 months.

Conclusions:

• Transforaminal Lumbar Interbody Fusion (TLIF) is a viable alternative to PLIF, offering potential benefits in spinal fusion.
• Meticulous surgical technique, including distraction and disc space preparation, is key to successful TLIF outcomes.
• TLIF provides a comprehensive approach for treating various lumbar spine pathologies requiring fusion.
