Trigger finger anatomy

Ғылым және технология

Also known as stenosing tenosynovitis, a clicking sensation at the base of a finger can progress to locking of the finger in a flexed position. There is some very interesting mechanical anatomy going on here.

    Thanks Sam! I just discovered you. As a massage therapist of 30+ years, I am now just beginning to have trigger finger symptoms in a couple of different fingers. Massage seems to help, and rest. So far, so good, but I am definitely aware of it when I massage clients and finding new techniques which gives my fingers a break. Thanks again!

    I've always kind of wondered how tendon pulleys and retinacula work as well as they do...and now I know why my shoulder clicks when going through certain ranges of motion! Great explanation of this phenomenon!

    Nope. I don't think anything like ChatGPT could replace such a marvelous Teacher. I can find text answers (and, as a really capable student, even pictures) by myself, but it's no near the effect of these videos and this way of describing.

    I had a trigger finger, middle finger on my right hand when I was in my late teens. But my finger, due to being broken as a kid, got stuck out and wouldn’t bend inwards, instead of the other way around. I had 2 surgeries trying to rectify the problem when my surgeon was sadly killed in a car accident and I never bothered to see anyone else about it. I figured 2 surgeries were enough, so it still gets stuck and I have to bend it with my other hand. Annoying more than anything these days. I’m just used to it.

    Thank you for this excellent video too! I just previously viewed your video on Dupuytren's Contracture (and left you a question therein) but seeing your video above may have helped me answer my own question. My question was, "How do Dupuytren's and Trigger Finger differ in their diagnosis?" I really thought I had 3 trigger fingers because when I bend them, they get locked and have a hard time coming up. They don't click at all on the way down - just get stuck when I try to extend them and click once they do unlock. I was diagnosed with Dupuytren's but was thinking it might simply be Trigger Finger (of course I'd prefer it to be Trigger Finger too). From your above video, I am assuming that if it were Trigger Finger I would feel a lump and sensitivity at the direct base of the finger. I don't. My sensitivity on each of my problem fingers is approx. one inch below the base of each finger. I remember the doctor saying he feels some lumps there too, and now that I compare those areas to the same areas on my 'good' fingers, I realize there ARE tiny lumps there. I think I can see now why I was diagnosed with Dupuytren's and not Trigger Finger - the lumps in Dupuytren's will form lower down on the palmar fascia whereas Trigger Finger lumps will be higher up and at the base of the finger. Is this correct? Thank you again for both fabulous videos. They have really helped me understand the anatomy of both conditions and therefore the conditions themselves. Ugh, I wish I didn't have Dupuytren's but knowing is important. Your time and great videos are much appreciated! Going to go search now to see if you have any suggestions on preventing early Dupuyten's from worsening 🤞🏼 Thanks again!

    Wonderful video lesson as always. I learn so much from your excellent teaching. Thank you! You did a video about bones and nearly got to talking about fractures. As I sit here recovering from surgery to repair a distal radial fracture (several pieces had to be realigned and they had to be kept together), I wonder whether you have created a video about how fractures heal. Where would I find it? Or are you planning to create a new video? I'd be thrilled and grateful to see what you can do about this.

    Good video Sam. I have trigger finger in my middle finger. Left hand. Right hand middle finger locks 🔒. I know the feeling. Had steroid in my left hand to ease the trigger finger. Any way I have a condition as well called Hemchromatosis.

    I used to have a "trigger" finger but not anymore. I never saw a Dr. or received treatment. I have no idea when my finger returned to normal. Glad it's gone, it was very annoying.

    My pinky locks and I’m unable to touch my pinky and thumb only with the help of my ring finger, I’ve been told nothings wrong but still have all these symptoms from pain, locking of my pinkiny, and there’s like nothing over my ring finger knuckle. I had a crush injury in July last year and it’s still giving me hell.

    I've talked about some regions of fascia in videos (neck, others?) but I usually need to use cadavers to teach about fascia during dissection. It's the only time you see it, as you have to remove the fascia to see what's underneath.

    Thank you for the informative video series. I am just writing to ask if anyone has had any luck with massage or stretching or any other non-surgical interventions that might be able to reduce the amount of collagen building around the tendons and/or decrease inflamation in the fingers? I'm 47 and only been climbing as a regular pass time for the last year or so, but have recently been getting some acute pain in my ring finger from climbing, as well as any work requiring a firm grip (e.g. forking a garden bed). Recently a muscuolo-skeletal specialist diagnosed me with early Depuytrens contracture, but I also hypothesize that my relatively acute pain during climbing may be caused by nodules on my finger tendons being pulling through the A2 pulley under pressure (I can feel a small ridge/bump pulling through when I lightly pinch my first knuckle with the other hand and then flex my finger). My main concern is that I may be worsening the condition the more I climb, and I've just had approximately a month break without the pain or finger swelling diminishing....

    I can open my index finger just fine but the last joint near the nail can't close well... The result it the index can't fully close, only about 80% which means I can't make a fist with that hand... If I force the finger closed, like with a rubber band it will stretch...and fully close after a few minutes..if I keep it closed for a while and remove the band, then for a little while after that I can close my hand into a fist with the index closing about 98%.... This problem started after picking up a heavy plastic bag and pulling the index finger... Occasionally there is a clicking after I stretch it but normally not and there is no pain... So far doctors no help and no confidence of a fix... Any thoughts?
