Question 1

mri shows small herniation
on l5s1, mass effect on s1.  numbness and pain are l5 dermatoes, eg big toe numbness, is this common?

Accepted Answer

Mismatch: Be careful about concluding abnormality is cause if pain reconcile with diagnostic injections mismatches are common in failed surgical attempts Look at l5 s1 foramen and other  cause of l5 root impingements need to work toward a reconciled confirmed diagnosis

Question 2

can anklosing spondilits/sacarolitis cause sciatica and l5 dermatoes big toe numbness.  mri does not show l5 impingement, only small mass effect on s1?

Accepted Answer

MRI can show inflame: The  MRI can help see sacroiliac inflammation when X-rays are  normal. This is called  non-radiographic sacroiliitis and spondylarthropathy. The symptoms you describe could be from ankylosing spondylitis but it is unlikely. Your physician can have you see a rheumatologist to clarify

Question 3

my mri says i have lateral recess stenosis, mass effect on my s1 nerve root, and facet authropathy diffusley from l2-s1. what's this mean for me?

Accepted Answer

Needs correlation: The films suggest potential compression of the s-1 nerve root, which might explain numbness over sole of foot and weakness of calf muscles, besides pain radiating from lower back to foot.  Could be treated conservatively, and may respond to epidural steroid injection, but if bladder involved, surgery is far preferable.  Do have lengthy discussion with spine surgeon.

Question 4

what does disk material at least abuts the thecal sac and right transiting s1 nerve root without obvious mass effect mean?

Accepted Answer

Disk against nerve: Without seeing you, or you diagnostic exam, the finding does not mean much. To make a diagnosis a careful medical history and physical examination is required to frame the results of your test. The best person to ask is your doctor. They can determine what the findings mean, and what may be done next.

Question 5

mri showed grade 1 l5/ s1 anterolisthesis and severe bilateral l5/s1 foraminal stenosis with mass effect on exiting bilateral l5 roots. my options?

Accepted Answer

Lumbar stenosis: Lumbar spinal deformities in form of varying degrees affects 6% of the population in the U.S,..THE treatment spectrum varies from avoiding activities that produce pain, bracing , physiotherapy, NSAIDs, to surgical interventions which involve decompress ions and or fusions. Recovery from surgery depends upon whether or not a fusion is performed , but can take up to 9-12 months.

Question 6

l4-l5: compressed, 8mm one side- other 16mm. l5-s1: bulging disc with a 5mm mass effect. shooting pain down my leg & numbness. will i need surgery?

Accepted Answer

Differs: Each person is different.  The overall response to conservative therapy (Physical therapy and Epidural injections and meds) depends on several factors: your weight, your core strength, your height, your genetic spinal canal width/height, etc.  If you are short and fat, you are much more likely to need surgery with the described disc.  If you are taller and slimmer, you are less likely.

Question 7

where is the l2-s1 located?

Accepted Answer

Do you mean L5/S1: L5/s1 is the lowest disc, between the 5th lumbar (most people have 5) and the first sacral segment.

Question 8

what does mean if i have narrowing of disk space in l4-s1 level?

Accepted Answer

Maybe nothing : Your spine looks on MRI like 30% of asymptomatic 30 years olds many narrow disc cause no pain at all 95% of backache ismuscularand resolves overtime and can be controlled w ith commonsense avoiding activities.

Question 9

what can i do if my s1 vertabrae is not fused. i've had 2 nerve blocks and no relief. where do i go from here?

Accepted Answer

Core strengthening: Ask for a referral to physical therapy. Maybe you have increased mobility in the spine due to weak core muscles.

Question 10

i will soon be fuse l3-s1. i love rollerblading,  but should i give this up or could it be safe for me again some day?

Accepted Answer

Rollerblading: Once healed, through physical therapy post-op and cleared by your surgeon, there should be no reason you cannot return to rollerblading.  Just don't fall!  In fact, it should be excellent exercise for your repaired lumbar spine.  Good luck.
