Alternatives to Lumbar Discectomy

Lower back paincan arise from many sources including facets, sacroillac joints, ligamental instability, muscular dysfunction and  the lumbar disc.  Discectomy is a   common surgical procedure for lower back pain where the disc bulge is surgically trimmed.  In the short term this may be beneficial but in the long term it can result  in progression of the degenerative process by compromising the integrity and blood supply of the disc.

The disc is composed of two principle components:  the  annular fibrous and nucleus pulpopus

The annulus is a ring of strong ligamental fibers that encircle the inner core of the disc.    The nucleus pulpopus is the inner core and is compromised of jelly like material. The annulus fibrous functions to prevent the nucleus pulposus from leaking out. It is best thought of as the sidewall of a tire. It is also the only part of the disc that has a significant blood supply. 

A discectomycuts through the sidewall of the disc thereby weakening the fibers that contain the nucleus pulpopus and compromising the blood supply to the disc.

Regenexx offers patients an alternative to surgical therapies by using their own stem cells to regenerate the damaged sidewall of the disc.  To understand the potential of stem therapy please click video.

Alternatives to Back Surgery

As a physician I have seen thousands of patients with lower back pain some of who go on to have back surgery.  Surgical therapies for back pain include discectomy, foraminotomy and fusion.  A discectomy is where a portion of the protruding disc is trimmed thereby relieving its compressive effect on the nerve root.

foraminotomy is opening the doorway (neural foramen) through which a nerve passes as it leaves the spine. Its goal is to relieve the compression on the nerve root.  neural-foramen

 

 

 A lumbar fusion removes the lumbar disc and replaces it with an artificial disc, spacer or bone along with stabilizing hardware.  The theory is that the disc is the pain “generator”.

Unfortunately with all back surgeries patients are exposed to the risks of surgery, anesthesia and extensive rehabilitation.  Another issue that is rarely addressed is failure.  That is to say that the surgery may not relieve the pain and can in some cases  makes it worse.  Surgery is a one way door.  Once the disc is trimmed or removed there is no turning back.  One year and 4 year studies have demonstrated no difference between surgery and conservative therapy in patients with low back pain.

Patients now have an alternative to surgery utilizing stem cell therapyRegenexx enables the patient to use their own stem cells to repair damaged discs.
