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.
When metacarpophalangeal dislocations do occur, they are usually dislocations of either the index finger or little finger (pinky). Symptoms. A dislocated finger is crooked, painful and swollen, and its surface skin may be cut, scraped or bruised. If a dislocated finger has been straightened on the playing field, it may feel abnormally loose, weak or unstable afterward. Diagnosis. Your doctor will suspect that your finger is dislocated if it appears deformed.
