Incorporating Posterior Interbody Fusion into Surgical

Interventions for Degenerative Lumbar Spine Conditions

For different degenerative lumbar spine ailments, posterolateral spinal fusion has been a well-established therapy for a long time. After its original explanation, only a few other methods have been introduced to accomplish lumbar spine fusion, such as posterior lumbar interbody fusion (PLIF) and unilateral transforaminal posterior lumbar interbody fusion (TLIF).

By expanding the compressed disc space and enhancing fusion in the load-bearing vertebral bodies that have ample blood supply, the integration of interbody fusion (PLIF/TLIF) enables nerve root decompression.

There are two approaches to performing interbody fusion: anterior and posterior. In comparison to posterolateral fusion (PF), incorporating posterior interbody fusion (PIF) is more intricate, has a greater likelihood of complications, and prolongs the duration and cost of the procedures.

Radiologic Parameters

Studies have demonstrated that incorporating the PIF approach indicates an increase in disc height and slip percentage, but there was a tendency for correction to diminish over time. Inadequate sagittal balance after surgery can result in degeneration of adjacent segments and unfavorable outcomes.

By utilizing multiple functional outcome assessments and conducting a thorough postoperative evaluation, the group treated with posterolateral fusion (PF) demonstrates better functional outcomes than those who received interbody fusion. The reason for this is ascribed to selection bias based on factors such as age, sex, degree of listhesis, and disc degeneration, as well as the retraction and scarring of the nerve roots and thecal sac.

Literature has demonstrated that interbody fusion achieves a high rate of fusion. The TLIF technique has yielded a 90% rate of fusion and an 85% rate of satisfactory clinical outcomes.

While PIF enhances the fusion rate, correction of disc height, and reduction of spondylolisthesis slip percentage, there are no notable distinctions in functional outcomes, final segmental or lordotic angles, and complication rates in comparison to PF.
