Dislocated finger joint occurs when an injury causes damage to the joint ligaments or capsule, such that the joint forming surface of a finger bone or phalanx is extruded out of the joint. Thus, a finger dislocation leads to failure of joint mobility and causes a stiff, swollen, and painful finger joint. Sometimes, a finger bone may also be broken along with the dislocation, in which case it is called a fracture-dislocation.
This can happen when you are outside in extreme temperatures without gloves, or when you hold onto something cold, such an iced beverage. However, fingers that turn white and go numb may also be a result of a condition called Raynaud's Syndrome. Another phenomenon that can cause whiteness and numbness is Vibration-Induced White Finger (VWF). It's similar to Raynaud's, but VWF is caused by using vibrating hand tools, like jackhammers.
