Hello, six fingers deformity, with finger bending after operation. Generally speaking, it is caused by joint degeneration after operation. Corrective surgery can be considered. If it recovers well, it will be almost normal.

I suggest you go to a regular hospital for hand surgery or plastic surgery for a step-by-step diagnosis and treatment, and decide the reasonable surgical treatment according to the film and the situation of your knuckles. I wish you happiness.
