Well, after the injury, first make sure there is anything wrong with the bone, and bounce your fingertips vertically to see if the whole finger hurts. Then slowly bend over and stretch to confirm whether the ligament is broken.

I don't know if your fingers are bent because they didn't grow well after fracture, or because the ligament rupture function died and you can't bend.

So you have to do a test. If you reset it with your fingers, if you can reset it, then the ligament is broken and it was not connected well at that time. I don't know which joint. If it is a terminal joint, it has no surgical value, so this is the only way. If it is the second or third joint, it can also have surgical value.

If you massage with your fingers, your fingers are a bone problem (fracture, bending, no reduction and no growth), so be it, don't reattach them if they are broken. Unless it is bent badly, it will affect the function.
