Finger injuries are common and range from minor cuts and scrapes to wounds with major damage to bone, tendons, and ligaments.
This finger injury isn't easy to treat because it shows multiple tissue damage, including the dislocation of the joint that causes a bone to move out of its normal alignment with another bone, ligament injury (sprain), tendon injury and probably nerve injury that causes numbness (loss of sensation). A finger may be injured by a direct blow or cut and many are work-related during which the finger is jammed, twisted, or stretched. It's prone to extensive bleeding due to rich vasculature.
In general, replantation or reconstructive surgery, when successful, provides excellent outcome by maintaining the digital length, preserving the nail and improving function and even sensation.
