I have heard many lectures in my life but this one is by far the best. What a magnificent job summarizing this topic! Thank you.

@theneurophile 3 года назад

Thank you. I took over a month to produce. Not an easy topic.

@wiltonpt1 2 года назад

I was wondering about the statement that cord compression released by flexion and nerve root relieve by extension. Straight leg raise tenses the dura and arachnoid and that is a kink of flexion. Conversely stenosis which affects roots is relieved by flexion. Any comments??

@theneurophile 4 года назад

Thank you. Please watch the Spinal Disorders video if you want to know about paraplegia.

@theneurophile 4 года назад

Paraplegia is more of a localization issue - bilateral medial frontal lobes vs spinal cord (at any level) vs peripheral nerve roots vs peripheral nerves. So neuropathy vs plexopathy vs radiculopathy vs myelopathy vs frontal pathologies. If you can identify the correct localization, pathology and management will follow. I'll make a localization video soon to explain.

Thank you for this amazing lecture! Is bladder dysfunction due to involvement of the sacral corticospinal fibres or motor autonomic fibres in the lateral horn. You seem to mention both.

Most likely due to sacral parasympathetic fiber involvement.

@theneurophile 2 года назад

Oh sorry, that was a "typo." Cervical vertebra end at C7. Thank you for catching that.

@johnrowland3105 Год назад

Still awaiting an 'official' diagnosis after a year of scans and 'terms' expressed in the occasional letters from hospitals and Consultants. Arteriovenus Fistula being the latest and oft used within them. When information is in short supply (to patients) you have to go looking for potential explanations (sadly). Of all the 'research material' i've been looking through, this video was more enlightening (maybe) Thank you.

@theneurophile Год назад

I'm very sorry to hear that you are having difficulties. I hope you receive a diagnosis and get treatment. I wish you a speedy recovery.

@farahazizi6764 2 года назад

Thank you very much for such a great explanation but i have one question In minute 4:10 you mentioned flexion decreases size of intervertebral foramina i looked it up it actually increases it or am i missing the point if so please do explain it if possible

@theneurophile 2 года назад

Flexion should decrease the size of intravertebral foramina while increasing the size of spinal canal. Hence flexion worsens pain from radiculopathy but makes the pain from spinal stenosis a little better.

@user-wr9ks3tf4n 2 года назад

hello doctor, can I ask whether the term "lower motor neuron lesions/signs" include neuromuscular junction disorder and myopathy? thank you

@theneurophile 2 года назад

“Lower motor neuron” only refers to the nerve. Neuromuscular junction and myopathy are technically different conditions.

@fhibanhes 2 года назад

Loveeee the lecture. Very impressed with the didactics. Now aren't there 7 cervical vertebrae rather than 8, as the video shows?

@theneurophile 2 года назад

Sorry, that was a typo. I'll fix in the update.

@didemkocabiyikoglu4587 3 года назад

Hi! I thought intervertebral foramina size reduces extension and increase with flexion?

@theneurophile 3 года назад

Intervertebral foramina reduces with flexion. One maneuver to bring on the pain of cervical radiculopathy is to tilt the head to the side and press down on the top (Spurling test).

Please What Is The Spinal Fluids Made Of It’s A Simple Straight Forward Question .

@theneurophile 3 года назад

Spinal fluid has proteins and nutrients necessary to protect and sustain the life of nerve cells.

@antonribkin5319 9 месяцев назад

I’m a bit confused about motor pathways damage and pattern of weakness If say both - anterior horns and corticospinal tracts would be damaged then what pattern of weakness (LMN or UMN) would the patient exhibit? Excuse my imperfect English Thanks in advance

@theneurophile 9 месяцев назад

That’s an excellent question. Anterior horns at each spinal level supply the muscles at that dermatome. But motor tracks are continuous. If you acutely damage motor tracks in the cervical cord for example, patients may have quadriplegia. Cervical cord lesions may also damage the cervical anterior horns, but since the arms will already be weak from motor track damage, the signs of anterior horn damage will be masked. So in general, with acute cord injury, motor track damage takes priority clinically. In chronic lesions (like motor neuron disease), you may be able to see lower motor neuron signs associated with anterior horn lesions (fasciculations, wasting, decreased reflexes) and/or upper motor neuron signs with motor tract damage (spasticity, Babinski, hyper-reflexia).

@theneurophile 4 месяца назад

@user-wr9ks3tf4n 2 года назад

Hi doctor, in 16:33 you said the sensory deficit deficit is in ascending pattern, however most lateral part of posterior column is the innervation of cevical area ; does the proprioception loss happen in descending pattern?

@theneurophile 2 года назад

Proprioception deficit with cord compression is really impossible to detect at the bedside, so we focus on pinprick/light touch instead. That is more reliable.

@user-wr9ks3tf4n 2 года назад

@@theneurophile very thanks for your reply.

@user-wr9ks3tf4n 2 года назад

@@theneurophile Can I ask whether the patient description of pain effectively differentiate pain between dorsal column compression , anterolateral system compression , or dorsal root compression?

@theneurophile 2 года назад

@@user-wr9ks3tf4n Description of pain is unfortunately very non-specific as well. Most compressive myelopathy presents with pain, and it's unusual to have cord compression without pain. But that's I can say with any reliability.
