Abstract

Background:

Unilateral biportal endoscopic lumbar interbody fusion (ULIF) with one cage results in fewer definitive fusions (Park et al. in Neurosurg Rev 42(3):753-761, 2019). We succeeded in inserting bilateral cages during ULIF.

Method:

We attempted posterior ULIF for degenerative lumbar spondylolisthesis with bilateral recess stenosis. With the help of a third portal, ULIF with bilateral cage insertion was performed under general anaesthesia.

Conclusions:

We successfully performed ULIF with bilateral cages with the help of a third portal. This procedure may be an alternative for treating lumbar stenosis with instability.

Keywords:

Bilateral cages; Lumbar interbody fusion; Third portal; Unilateral biportal endoscopy.
