Abstract
BACKGROUND: Despite of the evolution of endoscopic surgery, the literature on technique uniportal transforaminal endoscopic lumbar discectomy (TELD) for bilateral lesions is scarce. METHODS: Unilateral TELD was performed in a patient with bilateral superior and inferior migrated, broad-based disc herniation presenting with an impaired neurological state. The key surgical steps focus on free mobility in Kambin triangle with the mobile outside-in technique and accessibility to contralateral lesions with an extensive annular resection procedure. CONCLUSION: TELD can be a surgical option for treating bilateral multiple direction migrated lumbar disc herniation with benefits of minimal neural retraction and facet joint preservation.
