I have the same injury 8 years ago. My elbow seems to permanently lack extension range, hence 1 of the reasons that I’m hear. It’s caused issues, e.g. shoulder and wrist ‘freezing’, even hard growths in my wrists to stop me from performing handstands with poor elbow stability. Xrays generally reveal nothing for this type of injury. I’m going to trial consistent mobility exercises prescribed on this site. Also check for internal rotation bias, similar to tibial internal rotation on leg injuries (which I also have). Once the swelling has decreased look for consistent mobilization 7 days per week. Hanging and hanging twisting has been great for mine. Looking to get full range with other protocols found here now.
