Hand of Benediction vs the Claw Hand [feat. the Ulnar Paradox]

To misquote Olivia Newton John, let's get clinical, clinical, as we look at two nerve injuries with potentially similar presentations. We'll be looking at which nerves have been injured, how to tell them apart and unpicking the mysteries of the 'ulnar paradox'.

2:53-3:14 •ulnar: “claw hand” at REST [passive] •median: “benediction/ape hand” with FIST [active]

Excellent explanation. Thank you so much. On the theory portion of my first block anatomy, there was a question about this, and the question left hints that split this paradox right down the middle (and I personally thought that the picture provided was somewhat misleading) to make it a challenge. But I got it, and this video helped!

I have a doubt, in benediction deformity, why aren't 2nd and 4th digits doesn't get extended and MP joint and flexed at IP joints as 1st and 2nd lumbricals are damaged. Won't medial claw hand be caused?

@ardaburdurluoglu3868 Жыл бұрын

Hey! Great video! I just wanted to clarify, in minute 2:28 until minute 2:34, you say "flexor digitorum profundus have split innervation, lateral half is under median nerve control, but the medial half is supplied by the ulnar nerve." But the colours are a bit misleading? Because the median nerve is in blue, and lies medially to the red ulnar, which means the lateral side is innervated by the ulnar nerve. Should we go after the colors or what you said?

@Anartomy Жыл бұрын

Hi Arda! Thanks for checking, as I always worry about making these kind of mistakes! In this case though, I'm afraid both the narration AND the colours are the right way round. In the anatomical position, the thumb is the most lateral digit, so the median-innervated portion should lie closest to it, whilst the ulnar-innervated portion is found medially, passing to digits 4/5. I hope this helps!

@grahamlorsung88 Жыл бұрын

very good explanation except flexor digitorum profundus digits 2 and 3 are innervated by a branch of the media nerve called the anterior inneroussi

@Anartomy Жыл бұрын

Hi Graham - great point! I didn't specify the branch as I was worried about making the video too detailed, but you're spot on about the anterior interosseus nerve!

Hello, so I understand that Flexor Pollicis Longus is innervated strictly by the median nerve but I also know that Flexor Pollicis Brevis is a muscle that has a split innervation (median and ulnar nerve). In terms of hand of benediction condition, wouldn't the person be able to slightly flex their thumb if only the median nerve is being affected?

@Anartomy Жыл бұрын

Hi Erlyn, What a great question! You're right, the dual innervation of FPB would permit some flexion of the thumb (although it would be fairly limited). Apologies for the omission, I didn't want to overcomplicate the video/key diagnostic features!

@QpointXDz Жыл бұрын

@@Anartomy No worries! I just wanted to to make sure I wasn't mistaking. Awesome video none the less!

Will you be able to flex the index and middle fingers in claw hand?

@Anartomy Жыл бұрын

Good question! In ulnar clawing, only the medial two digits are affected, so you should be able to flex [and extend] the index/middle fingers as normal.
