COURSE 2

Transforaminal Endoscopy for Lumbar Disc Disorders

The GORE System | Operative Foundations Course

From Clinical Diagnosis to Targeted Endoscopic Surgery

Transforaminal endoscopy is not simply a smaller surgical approach. It requires an understanding of clinical indications, three-dimensional foraminal anatomy, instrument orientation, and surgical decision-making.

This course introduces the operative principles of the GORE System, developed from Dr. Satishchandra Gore's experience in transforaminal lumbar endoscopic surgery.

WHO SHOULD ATTEND?

Orthopaedic surgeons, neurosurgeons, spine surgeons, and surgeons beginning or developing their practice in transforaminal lumbar endoscopy.

Prior understanding of lumbar anatomy, MRI interpretation, and clinical diagnosis is recommended.

LEARNING OUTCOMES

Participants should develop an understanding of:

1. The anatomical foundations of transforaminal disc surgery.

2. Selecting appropriate patients and surgical targets.

3. Planning a safe transforaminal approach.

4. Recognizing key structures during endoscopy.

5. Understanding discectomy principles and adequacy of decompression.

6. Recognizing complications and procedural limitations.

7. Progressing from theoretical learning to supervised practical training.

EDUCATIONAL RESOURCES

Books: GORE System surgical manuals, anatomical illustrations, and selected chapters relating to transforaminal access and disc surgery.

Videos: Endoscopic anatomy, access techniques, operative demonstrations, and case analysis.

Practical training: Dervan hands-on training and structured surgical mentoring.

CONTINUE YOUR LEARNING

Course 1 — Clinical Diagnosis

Review clinical decision-making and symptom–MRI correlation.

Course 3 — Endoscopic Management of Lumbar Stenosis

Advance to foraminal, lateral recess, and central canal decompression.

Dervan Hands-on Training

Develop practical skills through structured, supervised learning.

This course provides professional surgical education. Online learning alone does not establish procedural competence or replace hands-on instruction, supervision, and appropriate credentialing.
