Question
I HAD A MYELOGRAM IT SAID UNDULATING DISK BULGE POSTERIORLY AT L4-5 WITH CALCIFICATION OF THE ANNULUS POSTEROLATERALLY ON THE RIGHT (WHAT IS THIS AND WHAT IS THE TX)

Answer
Dear Barry,

The basic problem here is that the L4/L5 disk material has pushed back into the spinal canal and is creating pressure and inflammation.  The calcification just means that calcium has been deposited in the outer ring of the disk (annulus) on the right side, and that it has become hardened.   Here is the good news:  the report says nothing about pressing directly upon the spinal cord or the nerve roots.

This presentation is a common problem today and occurs either due to injury, or chronic problems with posture and abnormal movements when lifting etc...   These are often degenerative in nature meaning that the problem started long ago with only a very small injury, and has progressed over time.  For a better understanding of the spinal anatomy and disk bulges, please feel free to visit my website:

Concerning treatment conservative measures should work well in your case, and if you stabilize the low back and disk material, you should not need a surgical intervention.  I would recommend that you seek out professional care concerning the implementation of a rehabilitation program.  The program should center around strengthening of the low back extensors, the abdominal musculature and the multifidus muscle (small stabilizing muscle located deep in the spine around the disk and facet joint).  Additionally, you may want to explore the option of decompression therapy to traction the spine and reduce gravitational stress on the disk itself.  

Chiropractic physicians and physical therapists all have training in lumbar spine stabilization, but often you can only get decompression at a chiropractors office.  However, physical therapists cannot by law diagnose or adjust the spine, therefore you may want to check out both avenues.

Lastly, there is a great book I would recommend that you read and you can get it online, or find it at a local library called "Low Back Disorders" written by Stuart McGill, and it is full of evidence based rehab guidelines.  It outlines injury and effective exercises to address rehab, and functional improvement.  Bottom line is that you need to address the issue soon, and get the care needed to stabilize the area, reduce pain, and increase function.  Good Luck Barry.
