More on our walk through the shoulder joint
There is more to managing shoulder pain and injuries than just x-ray and ruling out fracture. This short podcast starts with the rotator cuff.
More info here: http://wp.me/p2GZ98-A4
Quick and simple, likely not anything too new.
More detail on the wrist and in particular the Terry Thomas sign and carpal instability. As always there’s much more going on in the x-ray than just the bones.
Please check out radiopaedia.org.
And some cases from the podcast.
OK so this one is a little bit different than the usual but still some anatomy to learn. Check out emergencymedicineireland.com for the show notes.
Hi guys. This is yet another Zebra diagnosis but it’s a great one for illustrating some of the relevant anatomy. Let me know what you think.
Here’s the link to the article mentioned
Rudinsky, Sherri L, and Michael J Matteucci. “Emergency Department Presentation of Superior Mesenteric Artery Syndrome: Two Cases in Marine Corps Recruits..” JEM 42, no. 2 (February 2012): 155–158. PMID 19111427
Still in the skull but this time looking at the cavernous sinus.
The case report in the video can be found here
Yes I know it’s more circle of willis stuff but we’re getting there I promise you.

And a really neat one:
Continuing where we left of. This time you’re the patient…
The differences between ACA and MCA strokes in terms of vascular supply to the brain
The nice little picture of the brain in the case presentation can be found here
This is key knowledge I think – if you want to understand the stroke syndromes and the different presentations then you need to understand the internal capsule and its importance
This is a quick run through of the 3 main brain herniation syndromes. Enjoy
As mentioned in the video here are some of the cric resources out there on the interweb
And the final spinal cord video, if you have the er… spine… for it…
Here’s number 2. Let me know what you think
The very smart and astute Chris Nickson points out that central cord syndrome normally presents with motor weakness in the distally (in the hands) rather than proximally in the case in the video.
He is of course right and has a nice little mnemonic for remembering it MUD: Motor/Upper/Distal
And remember that the symptoms and signs are relative not absolute:
Based on the pure anatomy – with the corticospinal tracts arranged somatotopically with the highest spinal segments most medial – one would expect proximal weakness (C5,6 etc..) more than distal (C7-8, T1 etc…). But since when does the textbook play ball with reality! Maybe it’s just representative of the level of lesion in cervical cord (ie a lower lesion when the upper segments have already exited the cord) but it has me beat. Let me know if you have a better answer
Either way the more important thing is that central cord syndrome more usually presents with distal not proximal upper limb weakness.
Kudos to Chris for spotting it.
There was just too much good stuff for one spinal cord vid so I did three. They’ll be out over the next couple of weeks
Trust me CSF circulation is more relevant than you think.
As always, feel free to download and reuse or embed or whatever.
Let me know what you think
Here’s the next (not so) exciting installment. Thanks for the emails and encouragement. Some neuro stuff is in progress!
And if you have a slightly more accurate account of where the LisFranc story is from then I’d love to know
As always this is free to re-use as you see fit, it’s also downloable for free too. If there’s technical things that are bugging let me know and I’ll see if I can fix them.
In 10 minutes this is only a very brief look at the ankle, so there may have to be a part 2 to this.
