Sprain vs Fracture

By the AllHealth UK editorial teamLast reviewed Next review due Compiled from published NHS and NICE guidance. Not reviewed by a clinician.

Is it a sprain or a broken bone?

You often cannot tell without an X-ray — the NHS says a badly sprained wrist can be hard to tell apart from a break. Being able to put weight on it does not rule out a break — many broken ankles and wrists can still be walked or moved on. Suspect a fracture if the pain is severe, you cannot use the limb at all, or it has changed shape. Get any suspected break checked.

Immediate action required: call 999 or go to A&E if

  • A bone is sticking out through the skin
  • The limb has changed shape or is at an odd angle
  • The limb is numb, tingling, or has pins and needles
  • There is a bad cut that is bleeding heavily
  • You heard a crack when you had the injury
  • The skin around the injury looks blue or grey, or feels cold to touch

If you are weighing up whether it is bad enough to call, that is itself a reason to call. Nobody is annoyed by a 999 call that turns out to be the less serious of the two.
