Percutaneous Endoscopic Interlaminar Unilateral Ventral Dural Approach for Symptomatic Bilateral L5-S1 Herniated Nucleus Pulposus: Technical Note.
Percutaneous endoscopic lumbar diskectomy is a good treatment modality for lumbar disk herniation. However, when a patient complains of bilateral lower limb radicular pain with severe disk protrusion at the L5-S1 level, the transforaminal approach is often unable to resolve both lesions owing to anatomical limitations. It is also very difficult to resolve both lesions in an ipsilateral direction using the percutaneous interlaminar approach. We report our surgical technique and clinical results using a ventral dural approach of percutaneous endoscopic interlaminar lumbar diskectomy for L5-S1 herniated nucleus pulposus (HNP) in patients with bilateral radiculopathy due to a severe disk protrusion. ⋯ According to the results of this study, the ventral dural approach of percutaneous full endoscopic interlaminar lumbar diskectomy in patients with L5-S1 HNP associated with bilateral lower limb pain due to a severely protruded HNP is a good option for a minimally invasive surgical approach.
