What is

Minimally Invasive Lumbar Discectomy?


A Lumbar herniated disc may be very painful, but is often not permanent and can sometimes heal on its own. However, when necessary, a minimally invasive surgical option is the Lumbar Discectomy. The intent of this surgery is to cut away the portion of the disc which is pressing on the nerve; normally, only about 5% to 10% of the disc itself is removed. This surgery has a very high success rate and is helpful in relieving Sciatica, a pain which originates in the spine and then radiates down the back of the leg. For carefully qualified patients, the Minimally Invasive Lumbar Discectomy has become the gold standard surgery of choice, offering extremely favorable and predictable outcomes.

 

Microdiscectomy

Modern microdiscectomy technology enables the surgeon to reduce the potential for tissue damage by requiring an incision of only 1 to 1.5 inches, then utilizing a technique of spreading the muscles and ligaments apart instead of cutting through them.

Flouroscopic guidance https://en.wikipedia.org/wiki/Fluoroscopy imaging techniques are used to target the surgical field, utilizing X-rays to obtain real-time moving images of the interior of the body, allowing for surgical accuracy. Magnification enhances the visualization of the nerve sac and of the herniation itself. Precise repair and manipulation of tissue is granted by the use of bayoneted instruments, which gain access to the surgical site without restricting the view of the affected areas.

Patients usually leave the recovery room feeling less pain, especially leg discomfort, than they had before the procedure, and will experience a much more rapid recovery as compared to open back surgery.

 

Percutaneous and Endoscopic Discectomy

Outpatient procedures which are performed under mild sedation and with local anesthetics, Percutaneous and Endoscopic Discectomy are minimally invasive approaches accomplished through a tube, or several tubes, that require incisions of only a few millimeters. The tubes are guided into the lower back, creating create a pathway to make the injured disc area accessible to the surgeon. A wire is then inserted through the tube into the disc or the neuroforamen (the openings which act as exits for the nerve roots from the spinal canal). Cannulas are placed in sequence over the guide wire, gradually becoming wider to push apart the tissues with minimal damage. This procedure offers a path for the surgeon to perform the required repairs while remaining within a small operative corridor, resulting in less incisional pain.
