  author={Gun Moo Choi and Sang-Ho Lee and Arun Bhanot and Pradyumna Pai Raiturker and Yu Sik Chae},
Study Design. A retrospective analysis of 41 patients operated for excision of soft lumbar extraforaminal disc herniation (EFDH) by percutaneous endoscopic extraforaminal approach under local anesthesia by a new technique. Objectives. To describe a new and safer percutaneous endoscopic technique for the removal of soft EFDH and report the results on the basis of a new objective criterion modified from Oswestry Disability Index (ODI). Summary of Background Data. EFDHs usually occur in older… 


The study results demonstrated good to excellent results in Carefully selected Young Adult patients with single level disc herniation in Lumbar spine.

Transtubular microsurgical approach to treating extraforaminal lumbar disc herniations.

The dilative transtubular microsurgical approach combines the advantages of the conventional open muscle-splitting approach and the endoscopic approach and is easy to use with a steep learning curve, thereby contributing to a rapid recovery.

The Strategy and Early Clinical Outcome of Percutaneous Full-Endoscopic Interlaminar or Extraforaminal Approach for Treatment of Lumbar Disc Herniation

Percutaneous full-endoscopic discectomy through different puncture technique to remove the protrusive NP for LDH is a safe, effective, and rational minimally invasive spine-surgical technology with excellent clinical outcome.

Advantages of Endoscope-Assisted Disc-FX in Surgical Management of Lumbar Disc Herniation: A Report of 10 Cases

Disc-FX is a promising procedure in the armamentarium of minimally invasive surgery for the selected conditions of patients, and endoscopic observation is considered to be beneficial in more accurate and adequate decompression.

The Effect and Feasibility Study of Transforaminal Percutaneous Endoscopic Lumbar Discectomy Via Superior Border of Inferior Pedicle Approach for Down-Migrated Intracanal Disc Herniations

Foraminoplastic-PELD via upper border of inferior pedicle can serve as a safe and effective minimally invasive technique for removal of down-migrated herniations.

Suprapedicular Circumferential Opening Technique of Percutaneous Endoscopic Transforaminal Lumbar Discectomy for High Grade Inferiorly Migrated Lumbar Disc Herniation

Good to excellent clinical results were achieved using the SCOT of PETLD for high grade inferiorly migrated lumbar disc herniation in patients with back and leg pain.

Modified Endoscopic Access for Migrated and Foraminal/Extraforaminal Disc Herniation

This work proposes various strategies for PELD according to various types of disc herniation, including less paravertebral muscle injury, preservation of bony structure, and rapid recovery.

The effect of paraspinal muscle-splitting microscopic-assisted discectomy versus percutaneous endoscopic lumbar discectomy on patients in the treatment of far-lateral lumbar disc herniation

Compared with the PELD technique, the MD procedure affords a wider field of vision during operation, shorter operation time, fewer postoperative complications, and a shorter learning curve.

Transforaminal percutaneous endoscopic discectomy in the treatment of far-lateral and foraminal lumbar disc herniations.

Transforaminal percutaneous endoscopic discectomy is safe and efficacious in the treatment of far-lateral and foraminal disc herniations.

Percutaneous Endoscopic Interlaminar Discectomy for Intracanalicular Disc Herniations at L5–S1 Using a Rigid Working Channel Endoscope

Percutaneous endoscopic interlaminar discectomy is a safe, effective, and minimally invasive procedure for the treatment of intracanalicular disc herniations at the L5–S1 level in properly selected cases, especially when the transforaminal approach is not possible because of anatomic constraints.

Posterolateral Endoscopic Excision for Lumbar Disc Herniation: Surgical Technique, Outcome, and Complications in 307 Consecutive Cases

The surgical outcome of posterolateral endoscopic discectomy for lumbar disc herniation is comparable with that for the traditional open transcanal microdisceCTomy and intracanal and extracanals herniations, reherniations, and incidental lateral recess stenosis can be addressed by the same approach.

Foraminal and Extraforaminal Lumbar Disc Herniation: Diagnosis and Treatment

Surgical treatment with bilateral hemilaminectomy, partial medial facetectomy, and partial internal foraminotomy, if needed, followed by discectomy is very effective and the favored surgical management for nerve root decompression in most all cases.

The results of statistical analysis showed that the severity of damage to the nerve root and its response to conservative treatment were mainly related to the location of the protruding disc to the superior pedicle rather than the protruded disc in the foramen or extraforamen.

Microlumbar discectomy: a conservative surgical approach to the virgin herniated lumbar disc.

Microlumbar discectomy is an extremely conservative microsurgical procedure for the treatment of the virgin herniated lumbar disc that features no laminectomy or curettement of the disc space.

Far-lateral lumbar disc herniation: the microsurgical transmuscular approach.

The far-lateral approach is a muscle-splitting approach that allows surgeons to reach the disc herniation without any facet bone removal and the transmuscular approach is discussed.

Different surgical approaches to far lateral lumbar disc herniations.

No one technique of far lateral disk excision is applicable for the management of all lesions and it is more appropriate to choose the right operation for the right patient.

Unilateral facetectomy approach for lateral lumbar disc herniation.

Forty-one patients with herniated lumbar discs in a lateral location underwent unilateral complete facetectomy for removal of their disc herniation, and the results were excellent in 35 patients, good in three, and poor in three.
