Conclusion
There seems to be little doubt that if the decision is taken to reduce spinal deformity such as spondylolisthesis, it should be accompanied by anterior column support.

Modern implants and techniques have improved the ease of Posterior Lumbar Interbody Fusion (PLIF) surgery and greatly reduced the surgical risks.

The clinical results have become more reliable with many surgeons now reporting good and excellent results in over 85% of patients. As minimal access techniques and fusion bio-technology continue to develop we can expect to see the clinical outcomes continue to improve.
