    mallet finger, also baseball finger,[SUP][/SUP] dropped finger, dolphin finger and (more generally) extensor tendon injury, is an injury of the extensor digitorum tendon of the fingers at the distal interphalangeal joint (DIP).[SUP][/SUP] It results from hyperflexion of the extensor digitorum tendon, and usually occurs when a ball (such as a softball, basketball, or volleyball), while being caught, hits an outstretched finger and jams it - creating a ruptured or stretched extensor digitorum tendon.

    Swan neck deformity.perhaps. Rheumatoid arthritis? And the metacapophalangeal joints seems swollen it seems kind of arthritis,not just a trauma to finger.

    Correct Answer : swan neck deformity(hyperextension of PIP and hyperflexion of DIP )

    Rheumatoid arthritis is the most common cause of swan neck deformities

    This deformity also seen in ehlers danlos syndrome type II hand(hypermobility in PIP and DIP)
