Need tips for someone who has suffered from mallet finger?

A mallet finger: Is when the extensor tendon at the tip of a finger ruptures. The rupture of this tendon can involve the tendon alone, be associated with a small bone fragment or fracture or can be associated with a fracture that requires significant care. The fingertip joint cannot extend and droops or lags despite effort to activley extend. http://www.handctr.com/mallet-finger-baseball-finger-102.html.
