Doctor's Notes on Finger Dislocation
Finger dislocation is a traumatic injury that leads to the bones of the finger being moved out of their normal position. Trauma, such as overextension or a “jamming” force on the end of the finger, is the most common cause. A dislocation of the finger can occur in any of the joints of any finger. However, it is most common in the middle knuckle of the little, ring, middle, or index finger.
Signs and symptoms of finger dislocation include deformity of the appearance of the finger or hand, swelling, and pain that may be severe. Other possible associated symptoms and signs of a dislocated finger can include bruising, bleeding, numbness, tingling, an inability to bend or straighten the finger, and injuries to the overlying skin.
