I'm 19 years old. When I was born, there was a fleshy sack hanging off of my left thumb. After a surgical removal of the sack, they opened it up and saw that it was full of anatomical refuse, like bone fragments and ligaments. With that said, my actual left thumb was crooked, and it has been crooked my whole life. The proximal joint can bend too much with ease, all the way down to my palm, and it's very unstable and wobbly. The distal joint is where the crooked bend is at, and it cant bend enough. There's a sensitive lump of scar tissue where the sack was. And from what I've noticed, the thumb is the way it is because its tendons and ligaments are all screwed up and off center. It's not as strong as my right thumb. Basically the thumb is underdeveloped or it just developed wrongly. The only condition I know of that I can remotely relate to my situation is thumb hypoplasia. So my question is, is there any way I can undergo some sort of reconstructive surgery on my thumb to make it a little more "normal?" I only ask because I know that most of the operations for this type of thing happen during infancy, not adulthood.
