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.
Trigger finger is a snapping or locking condition of any of the digits of the hand when opened or closed. Trigger finger is medically termed stenosing tenosynovitis. Trigger finger is caused by local swelling from inflammation or scarring of the tendon sheath around the flexor tendons. These are tendons that normally pull the affected digit inward toward the palm (flexion). Usually, trigger finger occurs as an isolated condition because of repetitive trauma.
