Mri results said i had a large disc protrusion impinging on L5 nerve, and deformity of spinal canal/sacral nerve roots. Surgery? The report says: large 7mm posterior disc protrusion(l4-l5 disc)measuring up to 13mm in width. It is obliterating the right la

Right : Right l4-5 disk herniation can be treated with rest, physical therapy, medications, steroid injections and surgery. Surgery is a good treatment if the disk is causing right leg pain and you have failed other conservative treatments i mentioned. Today disk surgery can be done extremely minimally invasive through the spine endoscope. Please see my health guide on lumbar disk herniations. Good luck! ...Read more

Nerve (Definition)

The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more

Good First Step: As an anesthesiologist and internist, i completely agree with your surgeon. The first step is to evaluate your candidacy for either pt or transforaminal (ct- guided) injection before going to the slightly more invasive percutaneous, or open surgical, discectomy. It's wise to approach your condition "conservatively, " unless severe pain or loss of nerve function require more rapid action. No worries. ...Read more

I have MS and spinal stenosis. Emg shows l5-l4-s1 compression of nerve root. Orthopaedic surgeon won't do the surgery without neurologist ok.?

Cautious : I would guess the surgeon is being cautious to make sure that the neurologist agrees that surgery will help the problem. Stenosis of the spinal canal is different than neuroforaminal stenosis. Emg is usually normal in canal stenosis and is sometimes helpful in neuroforaminal stenosis. Just because you have something wrong on EMG and MRI doesn't mean surgery is the answer. Ask twice, cut once. ...Read more

You're the patient..: ...not the MRI. You didn't just wander into an MRI facility one day & make an impulse purchase. You saw a doctor with symptoms & signs and that's why an MRI was done. You need to repost with WHY you got the MRI. ...Read more

Mri-t12-l1 l4-l5 l5-s1 disk protrusion no nerve impingement or spinal stenosis. Left low back buttock leg pain ×3 wks. Foot cold tingling. Worse when sitting standing walking. 10 days steriod no help?

Mri-t12-l1 l4-l5 l5-s1 disk protrusion no nerve impingement or spinal stenosis. Left low back buttock leg pain ×3 wks. Foot cold tingling. Worse when sitting standing walking. 10 days steriod no help?

Delaying in this: Circumstance isn't advisable. Your symptoms suggest impingement, either through direct nerve compression or swelling around the nerve. In any event, a discussion with your neurologist/neurosurgeon about an epidural steroid (or transforaminal steroid) injection should happen sooner, rather than later. Although a cold, numb foot may be related to other (vascular) problems, nerve problems are primary. ...Read more

Conjoined l5/s1 nerve root on rt side after spinal fusion.Scarring in the spinal canal at l4-5 especially on the rt side intervertebral foramen ?

Conjoined l5/s1 nerve root on rt side after spinal fusion.Scarring in the spinal canal at l4-5 especially on the rt side intervertebral foramen ?

Conjoined nerve root: A conjoined nerve root is a congenital condition. It cannot be acquired from surgery. It does make surgery more difficult and the patient may be more prone to radiculopathy or nerve root problems. The larger nerve root sleeve that contains to spinal nerve roots is more easily injured. ...Read more

How is spinal retrospondylolisthesis of l4-l5 managed?

How is spinal retrospondylolisthesis of l4-l5 managed?

Depends on symptoms: Retrolisthesis occurs from degenerative changes in the disc and facet joints of the spine. It is generally considered more stable than a forward slippage and therefore a fusion is not always recommended if you are having nerve pain. Instead a simpler laminectomy can be done. If the slippage is significant leading to narrowing of the nerve exits (foramen), then a fusion is sometimes warranted. ...Read more

I have had a two-level spinal fusion (l5-s1). What is the best way to avoid (or prolong) adjacent disc disease?

Not much : Accelerated adjacent segment degeneration is relatively common and concerns adverse effects following spinal fusion. It is believed that this accelerated degeneration is due in large part to increased mechanical stress on the adjacent motion segments. Stay in shape, do not gain weight. ...Read more
