How I do It: L5/S1 foraminal stenosis and far-lateral lumbar disc herniation with unilateral bi-portal endoscopy
- 191 Downloads
Surgeries for far-lateral lumbar disc herniation (FLLDH) and foraminal stenosis at the L5/S1 level are very complicated because of its unique structure. The authors have performed unilateral bi-portal endoscopy (UBE) to these lesions because of the good results obtained for other spinal diseases (Park et al. in Orthopedics 40:e779–e783, 2017).
We described our experience of the surgical treatment for FLLDH and foraminal stenosis. Useful information for pre-, intraop-, and postoperative care is presented.
Among various minimally invasive surgical methods, extraforaminal approaches with UBE can be performed effectively.
