Why do splints help with sprains?

414 views

Hey, I sprained my finger. I just want to understand why exactly keeping the finger immobile in a certain position makes it heal faster.

When changing my splint, I noticed that it is pretty stiff and supposed the body itself tries to keep it still while healing. Why does movement harm it? I can’t find a more accurate explanation to sprains either. Nothing beyond “it is swollen and hurt” yeah I know but ligaments are a very weird material, just want to understand sprains and ligaments a little bit more fundamentally I guess.

OP, you can really bugger things up if you’ve sprained it bad. I made that mistake. If you see any bruising under the skin get to a doctor asap. I tore what’s known as the volar plate on one of my fingers. Yes they splinted it 3 weeks after I injured it. 18 months to heal. Can’t tell you enough to get to a doctor if you think it’s really eff’d up.
