At 5:00 : How could they have found the typical textbook anatomy in _37-77%_ of cases. How can there be such a big gap percentagewise? Thanks for the high quality video, keep it up (:
But what about the blank areas in the dermatome distribution? Are they so because they are considered variable? Because shown with all these gaps the map looks to me a little misleading, looks like there might be jumps in the innervation
Q1:Can radicular pain exist without any low back/ neck pain ? And if yes why is that ? If a netve root would be trapped wouldn’t that cause pain in that area too at least in the first phase ? I met a young guy ( 20 ) at the place where i do my practice training and he has radicular pain in his feet’s but never in his low back. Q2: Can nerve tightness/tension be caused by tight muscle or other structures that would cause this radicular pain ? I saw his MRI-s and as the doctor said there were no important deviations from normal.
@@Sawstinker because he told me he has this problem for almost 3 years, and initially it was localised around glutes and made it's way down his feets and it temained there. Also the pain increase woth prolonged sitting and lying flat. But walking is a relief. I asumed it may be radicular because whenever he puts the nerve in a elongated state he has pain. Like lasegue test, or simply making him touch his toes.
Q1: Less common, but yes. Radicular pain is caused by an inflammation of a nerve root often due to leaking disk material or longstanding ischemia and not so much the entrapment itself. Pain is felt along the distribution of the nerve due to ectopic discharge of the dorsal nerve root ganglion and not so much in the back/neck. Really biomechanically talking we would expect pain in the back derived from an irritated disk through afferents of the sinuvertebral nerves and not the nerve root itself. But let's remember that pain is a subjective experience and involves more than just biomechanics. Q2: Less probable as it would have to be a longstanding entrapment causing ischemia and inflammation. Radicular pain by definition is pain coming from the Radix, so the nerve root. There are other pathologies than a disk gerniation that can cause radicular pain such as cysts, tumors, infections etc.
3 years would be very atypical for a disk herniation causing radicular pain, but so would any red flags. Radicular pain is really shooting pain in the whole leg. If it's different, it's not radicular pain
Practitioners could learn a thing or two from this, great work as always!
Thank you for the informative video. A regular follower.
Fire content guys!

Based on different studies I guess, some of them say 37% some other 77% or something in between.
Thanks for your amazing work! Whats about the dinatoma?
Very useful clip for my orthopedist career.

Hello sir, i want to ask you how can i recover my muscle after truly workout. please give me advice. i am waiting for your comment.
Muscle recovery after workout?
Hello physiotutors. Thanks for your wonderful explanations. Could you pls teach us spasticity definition and physiotherapy management. Thank you.
No one expertise to be honest
@@Physiotutors Thank you

q1: yes
q2: yes
why do you assume it is radicular?

@@Physiotutors Thank you for making things a little bit clearer for me :D
What is the diference between: radicular syndrome and radiculopathy?
We have a video on that 😉
Can I now assume that other prominent ideas that have been taught should be questioned.
