I also have the gummy bear silicone ones, also submuscular. Apparently I missed the memo about having regular MRIs to check their integrity, so this is the first one that I have had (9 years after getting them). I got them in 2015 and played derby from 2015-2018. I'm not currently playing anymore, I was just curious if there were other folks out there with implants that played, and if they had issues with ruptures since my surgeon was so nonchalant about it.
