Congenital finger curvature deformity can be relieved by corresponding treatment, but it is impossible to cure it completely, it cannot be exactly the same as normal fingers, and the treatment effect depends on the characteristics of the deformity itself, it may be caused by tendon growth and development deformity, or it may be caused by bone development deformity, you should first go to the hospital to do a film examination to see what kind of condition the bones in the area are in. If there is no problem with the bone, it is a simple growth deformity such as tendon contracture, which is more effective than the bone developmental deformity, and the original shape can be restored through surgery, but the range of motion of the joint may be limited. If the deformity is caused by the bone structure, the effect may not be so ideal, but the surgery can also be very good at relieving the deformity in appearance and restoring a certain amount of joint function.
