BACKGROUNDS: Although open lumbar discectomy is a gold standard surgical technique for lumbar disc herniation (LDH), surgery-induced tissue injury may actually become a source of postsurgical pain. Percutaneous endoscopic lumbar discectomy (PELD) is introduced as a minimal invasive spinal technique for LDH. The PELD has gained popularity and shown successful results. The authors report the clinical usefulness of the PELD technique in two patients with the serial multilevel LDHs. CASE PRESENTATIONS: A 32-year-old man suffered from radicular pain at the L5 dermatome due to the down migrated soft LDH at the L4-5 level...

BACKGROUND: The anterior approach to lumbar spine surgery has grown in popularity in the past few years; spinal fusion of the last two lumbar levels is often required. While there are alternatives to bone grafting available, including recombinant human bone morphogenetic protein 2 or bone substitutes, only cancellous autologous bone has all the required factors for bone growth. To avoid the use of bone substitutes, remote iliac crest bone harvesting remains the gold standard. However, this technique may lead to some unfavorable outcomes...

BACKGROUND CONTEXT: Percutaneous endoscopic discectomy (PED) is a minimally invasive procedure for the surgical treatment of lumbar disc herniation (LDH). It can be performed under local anesthesia and requires a skin incision of only 8 mm, with minimal disruption of the spinal structures including ligaments and muscles. However, performing PED with a transforaminal approach (TF-PED) for the lower lumbar spine is associated with some anatomical problems such as interference from the iliac crest...

BACKGROUND: Percutaneous full-endoscopic discectomy (PED) is being increasingly used because of its potential to minimalize soft-tissue damage and decrease hospital stay. PED using the interlaminar approach (PED-IL) at L4-L5 is performed by only a few surgeons. To the best of our knowledge, the safety and efficacy of PED-IL at L4-L5, without experience in PED via a transforaminal approach (PED-TF) has not been previously reported. OBJECTIVE: This study aimed to evaluate initial clinical outcomes and complications of PED-IL at L4-L5 without experience in PED-TF...

BACKGROUND: Degenerative lumbar spinal stenosis (DLSS) is a common health problem in the elderly and usually associated with three-joint complex degeneration. Schmorl's nodes (SNs) are described as vertical herniation of the disc into the vertebral body through a weakened part of the end plate that can lead to disc degeneration. Since SNs can harm the spine unit stability, the association between DLSS and SNs is expected. The aim of this study is to shed light on the relationship between degenerative lumbar spinal stenosis and SNs...
