Does anyone remember the correct medical term for claw hand? I realize that claw hand is what is commonly used, but I have heard another term used as well that sounds much more scientific🙂
 
I think 'ectrodactyly' is the term for the so-called 'Lobster claw' congenital deformity, but is this what you're referring to? Or are you talking about something you see with, for example, an ulnar nerve lesion?
 
'Arachnodactyly' is the really long, skinny digits you see in Marfan's.
 
Yea im not talking about Lobster claw, which is a birth defect. I have a friend who lacerated his ulnar nerve. His pinky finger and his ring finger have now curled in. This is referred to as claw hand, but also has a medical term associated with it.
 
It appears to be referred to as claw hand deformity in ortho textbooks.
 
Dupuytren's contracture
 
That's congenital I believe, not the result of ulnar injury.

no, duputryen's contracture is an idiopathic fibrosis and contraction of the palmar fascia that tends to affect people of (IIRC) scandanavian descent. It is also a diesease of age.

Claw hand can refer to the appearance of the hand w/ an ulnar nerve lesion
 
Dupuytren's contracture

No it's not dupuy's.

I think ulnar claw hand is the correct medical name of the deformity subzero is referring to. Due to the loss of the intrinsic muscles of the hand (the lumbricals specifically) which are innervated by the ulnar nerve -- resulting in hyperextension of the 4th and 5th MCPs and flexion of the IPs.
 
Yea no one has named it yet. I have 3 good friends in their first year right now, and it was brought up at a party this weekend. I will just go ahead and see if any of them remember the name, and post it when I find out. Thanks for the help.
 
Are you one of those people who starts every sentence with "yeah"?

Volkmann's contracture?

edit: Oops guess not, I looked it up and that is due to ischemia to the muscles, not to nerve damage.
 
could it be Erb-Duchenne palsy...."waiter's tip palsy"?
 
Are you're talking about Klumpke Paralysis? It's cause by an injury to the lower trunk of the brachial plexus by upward traction on the shoulder(i.e. delivering a breach baby by the arms, etc.) This causes "claw hand" of the last two fingers.
 
The only other thing I have heard or read claw hand called (besides claw hand, and its etiologies) is intrinsic minus hand. But since the 1st and 2nd lumbricals are innervated by the median nerve, only the ring and small finger are involved in a pure ulnar lesion. Clawing is an accepted medical term describing the resulting deformity.

Winner. My friends did indeed call it klumpke paralysis.

why were you talking about this at a party?
 
How does Klumpke sound more scientific? personally reminds me of officer Klumpke from westside story.

second, i think we all can stand to brush-up on our brachial plexus knowledge.

third, why were you talkin about this at a party?
 
Med student parties are often lamed up by talking about medical things.

Haha it wasnt like we were at a huge house party. It was more like we were all at our house having a few beers making fun of how retarted our friend is, and a couple of the medical students brought it up. And yes, I think that it is not actually the right term. Anyways, this thread has gone on way to long. Thanks for all the help guys.
 
But you said your friend had an ulnar nerve transection. It would be inaccurate to call it Klumpke's paralysis.

If it's an ulnar nerve injury, it's called "claw hand," even by our local hand surgeon. 😉
 
If it is Claw Hand mixed with Tiger Stance I would call it the Wu Tang Sword Style.
 
a.k.a. The Hand of Benediction
 
the freedictionary.com says it is also called "main en griffe"

p.s. I think the black and white kitten is thinking "derp".

But this thread was an awesome read.

Your friend is definitely the retarted one.
 
isn't that axillary nerve damage?

It is actually damage to the C5 C6 root of the brachial plexus. But yes, this would affect the axillary nerve among others.

Oh, and you can have an ulnar claw (affects digits 4 and 5), a median claw (affects digits 2 and 3), or a full claw (all 4 digits)
 
Differential diagnosis, SDN style.
 
Yes, it is the term for a complete claw (Fr. "hand in claw" or "claw in hand") resulting from combined ulnar and median nerve lesion/injury.
Correct me if I am wrong, which is highly possible, but I think that wouldn't be a claw. There would be impaired digit flexion because ulnar and median nerves innervate all digit flexors, so extensors would dominate.

BTW, it is spelled retarded.

My favorite mnemonic from upper limb.

"DR CUMA" .
Drop-Radial, Claw-Ulnar, Medial-Ape..
 
med students try to make medicine seem alien and exotic to the people around them to be seen as intellectually superior, doctors try to make medicine seem as simple as possible so the patient can understand as much as possible about what they are going through
 
lol at this thread. 47 posts. all more or less completely on topic. lol at you, SDN.
