Q: MRI Explanations

Greets. I was in a workplace slip and fall in Feb 08 where I fell and my hip landed on a concrete curb. Since then I've been off work with unbearable back pain. I was taking heavy doses of oxycontin during the summer and now I'm down to percocet 5/325 4 times daily, Flexeril 2 times and Celebrex 200mg 2x daily. I've gone through 2 rounds of physio with little or no improvement and Workers comp is now reffering me to another specialist. I just wanted to post my results from my MRI taken back in Jun 08 to see if anyone could give me a better understanding of what's happening and why my lower back is still in so much pain. Many thanks.

EXAMINATION FINDINGS: The tip of the conus ends at the L1 level. There appears to be some fluid density within the more central
canal, higher up towards the T11level, and possibly in the cervical spine on the initial scout films. This area is not examined

completely on this examination.

There is a small rudimentary disc at the S1-S2 level.
At L3-L4 level, some mild diffuse bulging of the disc is present, but no prominent focal disc herniation is seen with the

traversing and exitings roots preserved. At L3-L4 level, mild diffuse bulge of the dsc is present. Mild degenerative changes in

the facet joints with no prominent disc herniation apparent. The central canal contains CSF is on the smaller side. At L5-S1

level, diffuse bulge of the disc is present with some minimal osteophytic lipping present. Some mild degenerative facet changes

are noted, slightly more so to the left side, however the traversing and exiting roots still appear to be preservered.

OPINION: There is diffuse bulging of the lumbar discs with some degenerative facet changes. Some small amount of fluid appears

to be seen in the central canal, which is not completely assessed on this examiation. If there is clinical concern, re:symptoms

then more extensive examination of the cervical and possibly the thoracic spine may be needed.

the conus is where the spinal cord branches out to form separate nerve endings kind of like a horses tail its in its normal place et the top of you lumbar spine the bit about fluid density has got me stumped it probably refers to an anomaly in the spinal cerebral fluid. which is the fluid that surrounds the spinal cord and brain.


"There is a small rudimentary disc at the S1-S2 level."


this has got me confused also S1-S2 refers to the top segment of the sacrum which is the bone in the middle of your pelvis its made up of i think five vertebrae that fuse together during childhood development the joins are visible but the discs have pretty much dissapeared in the normal spine i am guessing that you still have a disc at this level.




"At L3-L4 level, some mild diffuse bulging of the disc is present, but no prominent focal disc herniation is seen with the

At this level you have broad based bulge meaning the bulge is spread somewhat around the circumference of the disc the disc has not ruptured and the nerve roots that branch off the spine at this level are not compressed the facet joint are small delicate joints at the rear of each vertebra that help the joint move correctly they have mild arthritis at this level.your spinal canal is narrow here and contains spinal cerebral fluid.


"At L5-S1

level, diffuse bulge of the disc is present with some minimal osteophytic lipping present. Some mild degenerative facet changes

are noted, slightly more so to the left side, however the traversing and exiting roots still appear to be preservered."


this is the bottom joint in your spine another broad based disc bulge, osteophytic lipping is when you have small bony growths around the margins of the joints you have more arthritis in your facet joints at this level and again the nerve roots appear not to be compressed.
