Finger dislocation, also called a finger jam, is a common injury. It occurs when the bones of the finger are moved (dislocated) from their normal position. A dislocated finger can occur in any of the joints of any finger, but it occurs most often in the middle knuckle of the little, ring, middle, or index finger.
It has to do with your nerves, surprisingly. After a long bath or swim session, you've probably seen the pads of your fingers get wrinkly. While they return to normal soon after you leave the water, you can't help but wonder what's with the raisin-like look in the first place? YouTube channel SciShow has revealed the answer. At first, scientists believed osmosis caused fingers and toes to look like that. The influx of water, they thought, expanded the skin's surface area, but not the tissue below it, creating a puckered effect, reports Metro. That thinking changed in 1935 after doctors observed patients with nerve damage. One of them, for example, had nerve damage on three of his fingers.
