What is a Dislocated Finger Joint ?
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. Another situation is when the dislocation is incomplete and the joint surface glides in and out of the joint, when subjected to force in a particular direction. This is called subluxation, and is due to the laxity of the joint capsule or ligaments after an injury.
