=========================

Our MSK imaging tutorials continue. Today we review wrist MRI anatomy.

We’ll cover the bones of the forearm, carpal bones, dorsal wrist tendons, flexor tendons as well as intrinsic and extrinsic wrist ligaments. We also review the triangularfibrocartilage complex (including the triangular fibrocartilage disk proper, the ulnomeniscal homologue and the ligaments that surround the TFCC.

Easily identify these structures: radius, ulna, scaphoid, lunate, triquetrum, hamate, pisiform, capitate, trapezoid, trapezium, flexor digitorum profundus and superficialis tendons, the six dorsal extensor tendon compartments and their contents, the intrinsic wrist tendons (scapholunate, lunotriquetral) and extrinsic wrist tendons (radiocarpal tendons, ulnocarpal tendons).

4:22 Carpal bone anatomy
5:52 Tendons(flexor and extensor) on axial MRI

23:24 Triangular fibrocartilage complex (TFCC)
26:47 Summary

=========================

*Not sure if the question banks are for you?*
If you're here, you're likely studying for a radiology physics exam. I've spent the last few months collating past papers from multiple different countries selecting the most commonly asked questions. You'll be surprised how often questions repeat themselves!

The types of questions asked in FRCR, RANZCR AIT, ARRT, FC Rad Diag (SA), ABR qualifying Core Physics and MICR part 1 are surprisingly similar and the key concepts remain the same throughout. I've taken the most high-yield questions and answered them in video format so that I can take you through why certain answers are correct and others are not.

Happy studying,
Michael

As an MSK radiology trainee, I found your videos super helpful! Thank you!!!!

MRI Report:

1. Ulnocarpal Disc (Discus ulnocarpalis):



Firmly attached in all directions, with a slightly heterogeneous internal signal at the attachment of the ulnar styloid process.

Differential diagnosis (DD): Possibly post-traumatic changes or early degenerative alterations.

2. Extensor and Flexor Tendons:



Hypointense signal throughout their course, with no signs of inflammation.

Clinical Condition:

I have chronic pain on the ulnar side of my wrist and hand, extending toward my little finger.

Writing and typing are painful for me.

Fine movements, like playing with my beard, also cause pain.

My wrist appears to be stable from what I can observe.

Supination and pronation, hurt me a little. Not so much that it's unbearable, but on a scale from 0 to 10 its 4)

I don't feel tingling or numbness, so I think it's not a peripheral nerve issue.

But I've had pain in other parts of my body before that had no physical cause, likely due to psychological factors.

Question: "MRI reports, as far as I know, are not very accurate when it comes to TFCC. Now, I want to know, based on what is written in my MRI report, can it be said whether I have a tear in my TFCC, or is it just a small heterogeneous signal indicating that it is not a major, significant injury but something that can be stabilized through physiotherapy? Can a definitive answer to my question be given based on my clinical examination and MRI report without arthroscopy?"

Should I necessarily undergo arthroscopy, or can it be improved with exercises?

even though the MRI report does not mention a tear in the TFCC, is it still possible that there are undetected tears in that area?

Additional Information:

I've had this pain for about two years.

I have tried treatments like PRP injections and immobilization, but they have not helped.

Thanks! Your lectures are extremely helpful

[khushalkhan]

GREAT!! both your videos and your looks as well

[karlwagner]

How important are those extrinsic volar and dorsal ligmaments in daily practice? I've never paid much attention to them but I also rarely look at MSK images.
Thank you for your excellent videos!

[euhype]

My favourite joint! The scaphotrapeziotrapezoidal joint...try that one voice recognition!

[MusicYoutube-su]

Hi doc, may I ask why doctors order mri to a hand injury than xray?

Thank you

[maliqaziz]

Thank you! A big help. Great timing too 😁 Looking forward for more videos from you.

[Drparihar-svfl]

Very excellent video.. Btw intersection syndrome occurs due to crossing over of 1st and 2nd dorsal compartment..

[mehreengul]

Sucha comprehensive lecture . You are amazing👌

[GuruprasadMehetri]

Sir your teaching is excellent. please take a class on MR spectroscopy

[RachelWaters-ezjq]

Please could you do one on approaches to wrist/hand fractures on xrays. Particularly on metacarpal fractures? Your shoulder xray was is brilliant and so useful as an EM doctor!

[hameedaklan]

Fantastic as always, wish you the best

[anjalimagan]

Thank you again 🙏🏽✨ some further anatomy suggestions: cardiac system and it’s main vessels, cranial nerves.
We appreciate all your effort 🎉

[drrehmatrahi]

Very usefull and systematic video. Sir ! Please make a video on spine also.Thanks

[Awjabaefar]

👏 Please make more anatomy videos. Especially lower limb MRI

[vasanthasadineni-btuo]

How to know wether i have a tfcc injury or not sir in mri

[atamelangnkwamba]

Thank you for the insightful lecture doc😊

[zakariyanakhooda]

Hi. Video is awesome as usual. I'm just confused over the orientation of the wrist in the axial plane. Why is the anterior compartment at the bottom? Is it not standard in an axial section to position the patient so that superior = anterior?

[MistaKasko]

So glad to have you back. We need you working in over drive, only 1 month to go until the exam! Ahhhh!
