Supplementary posterior fusion in patients operated on employing TLIF may decrease the instrumentation failure rate.

Study Summary:
This retrospective study evaluated the clinical efficacy of circumferential fusion in 179 patients with degenerative lumbar stenosis and instability who underwent transforaminal lumbar interbody fusion (TLIF). Of these, 118 received additional posterior fusion. The follow-up period was 24 months, and the impact on pedicle screw loosening and complication rates was assessed.
Key Findings:
- Pedicle screw loosening was associated with lower radiodensity and was more common in two-level fusions.
- Loosening correlated with anterior nonunion but decreased with both complete and incomplete posterior fusion.
- Lumbosacral fusion, bilateral facet joints resection, and laminectomy were not significant factors.
- Additional posterior fusion was found to potentially reduce the rate of instrumentation failure requiring revision surgery (Odds Ratio: 24.98507; 95% CI: 3.209265 to 194.5162; p = 0.0023).
Importance:
The study suggests that circumferential fusion, including additional posterior fusion, can decrease the rate of pedicle screw loosening and clinically significant instrumentation failure in TLIF procedures. This finding is significant for surgical planning and could influence postoperative outcomes.
Contribution to Literature:
This research contributes to the ongoing debate about the necessity and efficacy of additional posterior fusion in TLIF surgeries. It provides evidence that supports the use of circumferential fusion to enhance stability and reduce complications.
