So I tweaked my left ring finger a few weeks ago. I noticed it during a warmup at the gym. I probably did it a few days before on a steep, crimpy boulder problem outdoors, but didn’t notice any pain or soreness at the time.
It’s my left ring finger. The soreness is on the palm side of the middle phalanx (second pad), towards the pinkie side of the finger. It’s marked in the picture.
There's no noticeable swelling, and I have full ROM in the finger.
It only hurts in a closed crimp - if I leave my thumb down it seems OK. I find this confusing, as the loading of that portion of the finger doesn't seem to change much when I move the thumb over the tip of my index finger.
The soreness seems too distal to be the A3 or part of the PIP joint, and too proximal to be coming from the DIP joint. It’s possible it’s the proximal end of the A4, but I don’t think the A4 is loaded at all when crimping (see this picture: carutacufraieri.blogspot.com/2009/02/cripple-club.html).
In pictures of finger anatomy this looks like the position of a cruciform pulley (C2), but I can find very little information about cruciform pulleys. Most articles just acknowledge their existence without mentioning anything about function. It does seem that they have similar function to annular pulleys: keeping the flexor tendons running close to the bone.
Could this be a C2 injury? Does anyone know anything about C2 injuries? Any other ideas?
I suppose I ask mostly out of curiosity, as it seems that the path forward is a bit of rest, then carefully loading it through very light hangboarding, which I've started already.
Thanks.
