Summary and References: Part 4

Endoscopic spine surgery has a high learning curve, but is within the grasp of every endoscopic surgeon with proper training.

Indications for Foraminal Endoscopic Surgery: Part 2

Most disc herniations are amenable to endoscopic disc excision and the timing of surgical treatment is similar to transcanal discectomy.
