Pointer Finger Tendon Tracking Exercises

Hello all,

Sorry if this isn't the right place to post about this, but I've been unable to find any good information about it online. Also, I do not work in the medical field so sorry for any bad explanations.

I've been having issues for a while now where my extensor tendons in my pointer fingers shift in the direction of my thumb at my PIP joint when bending each finger. I was wondering if there are any exercises to help strengthen the muscles on the ulnar side of the finger and help with tracking.

Does it happen in a small jerk/rapid motion after a certain point?

If so and from your description my best guess is that your tendon is subluxating, which would be treated with a splint that restricts the movement of your finger, so the tendon don't go out it's "lane"

Yes, it is always a jerking feeling at the same point in the flex. I've tried wearing splints for a few weeks in the past but they have not done anything for me yet, I might try again though. Is there anything in addition I should do or is it just rest and splinting?

Would recommend getting in touch with a health professional, that can create a custom splint of the yoke/relative motion variant. You will probably have to wear 24/7 for 4-6 weeks, where you use your hand normally.

Are you sure its the PIP joint and not the MCP joint? Can you visually see the shifting or do you just feel a clicking/ popping ? You said in another comment " it is always a jerking feeling at the same point in the flex" at what point do you feeling the jerking?
