Background:
Various full-endoscopic techniques have been developed to reach the lateral recess of the lumbar spine. However, specialized surgical tools, including expensive spinal endoscopic systems, and a steeper learning curve to mastering the technique are required.
Method:
We present a novel target-addressed unilateral biportal endoscopic technique to reach directly the lumbar lateral recess, particularly useful at L4-L5 and L5-S1. The technique follows an inclined-ipsilateral trajectory to preserve the lateral extension of ligamentum flavum and the facet joint as much as possible.
Conclusion:
This technique was associated with all the advantages of minimally invasive decompressive procedures and outstanding outcomes.
