What Is A Interbody Fusion (TLIF/XLIF/ALIF)?
Interbody fusion refers to a surgical procedure that involves the removal of a damaged intervertebral disc and the insertion of a bone graft or an implant into the disc space. This procedure aims to promote fusion (joining) of adjacent vertebrae thorugh creating a solid bone bridge that stabilizes the spine. Moreover, several techniques for interbody fusion include Transforaminal Lumbar Interbody Fusion (TLIF), Extreme Lateral Interbody Fusion (XLIF), and Anterior Lumbar Interbody Fusion (ALIF).
All these interbody fusion techniques aim to restore disc height, decompress neural structures, and promote spinal fusion to stabilize the spine. The specific approach chosen depends on factors such as the location and extent of the disc pathology, the surgeon’s preference and expertise, and the patient’s overall health. It deems important to consult with a qualified spine surgeon to determine the most appropriate surgical technique for an individual case.
Types of Interbody Fusions
- Transforaminal Lumbar Interbody Fusion (TLIF): This technique takes on a osterior approach where the surgeon accesses the spine from the back. Additionally, it involves removing the entire disc through a small incision, decompressing any pinched nerves, and inserting a bone graft or interbody cage into the disc space. The procedure typically involves the use of screws and rods to stabilize the spine while fusion occurs.
- Extreme Lateral Interbody Fusion (XLIF): This technique takes on a lateral approach where the surgeon accesses the spine from the side. Moreover, it involves making a small incision and creating a pathway through the psoas muscle to access the disc space. After surgeons remove the damaged disks, the surgeons then insert a bone graft or interbody cage. This technique avoids the disruption of the posterior spinal elements and allows for fusion without the need for posterior screws and rods.
- Anterior Lumbar Interbody Fusion (ALIF): This last technique uses an anterior approach where the surgeon accesses the spine from the front. It involves making an incision in the abdomen or flank area and retracting the organs to access the spine. Once surgeons remove the damages discs, a bone graft or interbody cage is inserted into the disc space. Additionally, fixation with screws and rods may be used from a posterior approach to enhance stability
