Why can’t I straighten my fingers when bending my wrist at a 80 degree angle?

I have never been able to lean on my hands and straighten my fingers. I was never too concerned about this however, since I started exercising I cannot hold my body weight when planking due to my fingers crunching up into a fist. Whenever I do attempt straightening my fingers I can feel a tight pulling pain on wrist ligaments. Is this a condition as I don’t know anyone else experiencing the same difficulties as me?

Have they looked into any abnormalities with your tendons? This sounds like it has been going on for a good while.  Do you have any lumps around the area where you can't straighten your fingers?  This article is a full list of issues related to hand and wrist, it's excellent. https://www.urmc.rochester.edu/orthopaedics/hand-wrist/conditions.cfm  Copy and paste into your browser and tell me if any seem to follow your symptom pattern.

Thank you for your reply! I have never really spoke to a doctor about it, however I am considering it now that it’s affecting me more. Yes, it has I can remember having this problem from when I was 8 years old, now I’m 21 and no I don’t have any lumps. I have read through the article and unfortunately I’m struggling relate to any of the symptoms. However, I have released that it’s only at Proximal Interphalangeal (PIP) Joint where the pulling sensations begins when bending my wrist and straightening my fingers. I have always been a bit conscious about the size of my PIP joints, as I have often been told that I have ‘man’ hands due to it, I don’t know if that has anything to do with it.
