 | | The extensor tendon may be injured by a blow to the tip of the finger, forcing the distal interphalangeal joint into flexion and rupturing or partially rupturing the extensor tendon slip at the point of its insertion into the base of the terminal phalanx. |
 | | This type of injury is characterized by pain, swelling, and tenderness at the distal interphalangeal joint, as well as the inability of the athlete to actively flex at this joint while the proximal and middle finger joints are held straight. |
 | | Rupture or avulsion of the flexor digitorum profundus tendon from its attachment to the distal phalanx, is caused by a sudden extension of the DIP (distal interphalangeal) joint while held in flexion. |
