- Dr. Ebraheim’s educational animated video describes the positions of the hand and fingers associated with injury to the ulnar and median nerves.
The position of the hand can determine what kind of nerve injury thet patient may have.
Ulnar nerve injury:
1-claw hand
2-Wartenberg's sign
3-cannot cross the fingers
injury to the ulnar nerve may produce a ‘claw hand’ deformity. The deformity usually occurs if the injury to the ulnar nerve is below the elbow. Flexion of the fingers occurs due to a functional profundus muscle for the 4th and 5th fingers. Wartenberg’s sign is due to a low ulnar nerve injury and consists of abduction of the 5th finger caused by unopposed ulnar insertion of the extensor digiti quinti. As a result of ulnar nerve injury the patient is unable to cross or abduct the fingers. Adduction of the fingers come from the palmar interossei (PAD). Abduction of the fingers come from the dorsal interossei (DAB).
The Forment’s test is used to test for palsy of the ulnar nerve which may occur with entrapment of the ulnar nerve within the cubital tunnel (cubital tunnel syndrome). When pinching a piece of paper between the thumb and index finger, the thumb IP joint will flex if the adductor pollicis muscle is weak due to ulnar nerve palsy.
Median nerve injury:
1-hand of benediction
2-cannot do the OK sign.
Prolonged compression or injury of the median nerve at this level may result in the “hand of benediction” . the ability to flex the 2nd and possibly the 3rd digits is lost due to loss of innervation of the lateral two lumbricals of the hand. The hand of benediction is different from an “ulnar claw hand”. Ulnar claw hand refers to damage to the ulnar nerve and is seen when attempting to extend all the digits (leaving the 4th and 5th digits flexed).
The O.K sign is used to check for paralysis of the anterior interosseous nerve due to entrapment or compression injury. Patient with paralysis of the anterior interosseous nerve will be unable to make the O.K sign. typical pinch attitude associated with anterior interosseous nerve injury.
Radial nerve injury:
1-wrist drop
2-cannot do the hitch hike sign
3-will be able to extend wrist but unable to extend fingers
injury to the radial nerve will cause wrist drop. High radial nerve injuries usually occur due to fractures of the distal third of the humeral shaft. The fracture may cause injury to the radial nerve which results in paralysis of the wrist and finger extensors. The patient will be unable to perform the “hitch hike” sign of finger extension. Low radial nerve injury usually occurs around the elbow affecting the finger and thumb extension. If the patient does not have wrist drop, and still cannot perform the “hitch hike” sign, check the patient for posterior interosseous nerve injury. Patient with posterior interosseous nerve injury can perform wrist extension, but no finger extension. Recovery of the wrist extensors, but finger externsors are not yet recovered is a sign of posterior interosseous nerve injury that is not recovered yet. With the wrist placed in extension, the patient cannot extend the finger= posterior interosseous nerve injury.

You taught me better than my doctor !!
I had open heart surgery (successful) but awakened to a paralyzed right (dominant) hand. I would be grateful to hear from anyone who recovered the use of their hand after the nerve damage.

Warning to all: I've had ulnar nerve damage on my left hand from my
stationary exercise bike's PULSE SENSORS. They've been zapping my nerves
because I sort of had it under my hands most of the time and overused.
Me also ..... how you feel now ? Because my hand still so painful and not even working it's atrophied
Had a distal phalanx fracture and deep laceration on right ring finger at work hand will extend open but painful will go back to being closed after letting it do so
Hey Doc i cannot extend my thumb and flex it too. I had a facture in ip joint. How can i get my range back. Its been 4 months. Swelling is still there
It hurts at the base of my thumb close to my wrist while I do the ok sign.
I have lost my finger extension and muscles in hand.. cervical Nerves are pinched.. any treatment?
I can't up my thumb and index finger what's the problem please tell me
Sir i hv the same problm help me
I accidentally cutt my three last fingers (pinky ring & middle) I currently have stitches but I can’t bend my fingers at all. Not because of how swollen because my antibiotics took care of that and not because of the stitches because I can make my finger bend myself and no pain. I can’t mentally bend my fingers. But I can move them side to side it’s like I have nerve damage to the complete tips of my fingers. My injury happened a little more than a week ago. Any advise or tips or anything I’m kinda trying to avoids hospitals with this virus
After 3 month of cutting my fingers also cant bend

nerves are one of the most complicated things. I had my median nerve, that was cut in my wrist, transplanted from my leg ~75 days after the accident. the muscle nor the joint was injured, it was just the nerve that was cut. 4 1/2 years ago, at the time 16yo, I was rushed to the hospital in a complete shock-state, as if I was on some drugs that made me physically numb. it was quite a deep cut and around 2 inches long with skin that was also hanging still. the doctor who cleaned up the wound had told me that the nerve wasn't damaged, but a few weeks later it turned out to be otherwise. I couldn't feel 3 fingers which I used to write with. the length from the cut up until the end of my middle finger is about 25-30 centimeters. I'm used to the numbness now and I can feel when my fingers are warm/cold, and tell the difference between warm/cold water easily.
nearly half of a decade has passed after this incident that was caused by glass. I still regret how I reacted, because I was upset about something, so I punched a glass door. that's life, though. I punched the middle of the glass and my hand went right through it. the thing that I'm most thankful for is that the glass didn't chop my arm off, which would have obviously been the worst outcome. glass was hanging from the top of the door frame and thankfully, it didn't fall down right after the moment my hand went through it.
I had bicep surgery recently. Surgery was successful but now I lost feeling in my index, thumb, middle and part of my ring finger. It feels like when your arm falls asleep then you move it to get blood flowing and it goes away. But this time it's permanent.
I told my parents I have the wartenberg sign and they laughed and called me a freak
Treatment ???????????????????????????
I think im the only person Whos here because theyre writting a character oof
