Mallet finger

Condition in which the topmost finger bone is bent towards the palm of the hand and cannot be aligned with the other bones, caused by tearing of the upper finger tendon by an excessively violent movement of the topmost joint. This often happens in sports such as volleyball when the ball strikes the fingers awkwardly. Treatment is by restraining the finger in a state of slight overtension with a splint or plaster for about 4 weeks. It is important not to immobilize it for too long, because it may stiffen through shrinkage of the ligaments and capsules of the joints.
