I have Stablyx implants in both thumbs. My right thumb was done 10-6-17 & the left was done 2-6-18. I have had great results. I was in a splint for about 3 weeks and then exercises on my own at home. I occasionally get some stiffness and mild pain in my right thumb if I over use it. I am not sure if that is normal or if it is because I have autoimmune inflammatory arthritis.
