I have it in my left little finger and have had corrective surgery twice in the same place, last time was September last year, and it was contracted almost 90 degrees, it back to about 40 degrees now and that’s the best I can expect.
I was told depending on the joint affected it can either be released fully or may be permanently bent, below is what it looked like before the last surgery. as mentioned above it will keep you off the bike for a few weeks.
I’ve also go it in my thumb and on the palm of my hand but as yet they are not causing any issues.
Has anyone else in the family got it? Any Vikings in the family ;-) ?
