Stem Cell Therapy for Lumbar Disc Protrusions

Lumbar disc protrusions can cause lower back and leg pain which can vary from mild to severe.

Today in clinic, I had the opportunity to followup with a patient who underwent autologous stem cell therapy using the Regenexx procedure.  He has kindly allowed me to share his experience. Patient is a 37-year-old male with longstanding lower back and leg pain.  The back pain was sharp in character, constant in duration, progressive in nature and aggravated by coughing, sneezing and flexion.  He would experience episodic pain which would incapacitate him.  Physical examination was significant for lower back pain aggravated by flexion, extension and straight leg raise.

Micro-discectomy and other surgical treatments were dismissed by the patient and his family.

 4 weeks after having his own stem cells injected into the L5/S1 disc along with platelet derived growth factors, the patient had significant reduction in his back and leg pain.  MRI prior to and after stem cell therapy was significant for a reduction in the L5/S1 protrusion which is illustrated below.

MRI of Lumbar Spine: Stem Cell Therapy

The lumbar disc functions as a shock absorber.  There is a lumbar disc between each lumbar vertebral body.

Lumbar discs are compromised of a supportive side-wall called the annulus fibrous and the inner gel referred to as the nucleus pulposus.  With degeneration there is weakening of the side wall with bulging of the disc.  The disc itself also looses height and brightness.  On the MRI, the disc will be shorter and darker.

To strengthen the side wall, patients can undergo the Regenexx  procedure where their own  mesenchymal stem cells are injected into the disc. This regenerative in design as opposed a    microdiscectomy where a “nip and tuck” is performed on disc protrusion.  This latter procedure disrupts the integrity of the disc and increases risk of degeneration and recurrent protrusion or herniation.
