Summary
Current evidence does not favor one lumbar spine fusion technique over another for degenerative conditions. Anterior interbody fusion may offer better outcomes than posterolateral fusion, with fewer risks of adjacent spinal stenosis.
Area of Science:
- Spine surgery
- Orthopedics
- Neurosurgery
Background:
- Surgeons hold differing opinions on the optimal lumbar spine fusion method.
- Techniques are used for deformity, disease, trauma, and degenerative spine conditions.
Purpose of the Study:
- To review conceptual and technical aspects of common lumbar spine fusion techniques.
- To discuss expected clinical outcomes for various fusion approaches.
Main Methods:
- Literature review.
- Incorporation of personal surgical experience.
Main Results:
- No single lumbar spine fusion technique is definitively superior for degenerative conditions.
- Anterior interbody fusion shows promising outcomes compared to posterolateral fusion with internal fixation.
- Posterior fusion procedures may increase the risk of adjacent spinal stenosis over time compared to anterior fusion.
Conclusions:
- All lumbar spine fusion techniques carry significant risks, including neurological damage (posterior interbody) and vascular injury (anterior interbody).
- Spinal fusion should be performed by highly trained and experienced surgeons.
