Mallet Finger

The mallet finger is a flexion deformity of the fingertip by demolition of the extensor tendon caused with or without fracture, from the proximal end of the distal phalanx.

The usual mechanism is a forced flexion of the distal phalanx, usually by impact of a ball. The extensor tendon may form part of the proximal side of the distal phalangeal bone avulsieren (mallet finger.). To the demolished part includes the joint surface.

The affected dorsal interphalangeal (DIP) joint remains in a gebeugteren position than the other DIP joints and can not actively stretched, but are passively stretched, usually with minimal pain. Mallet finger. The extensor tendon is pulled from the proximal end of the distal phalanx (top); sometimes the tendon avulsiert a piece of the distal phalangeal bone (bottom). Diagnosis Clinical examination X-rays A mallet finger can usually be diagnosed by examining the finger. Anteroposterior, lateral and oblique radiographs are taken as a rule. A fraction, if present, is usually visible on the side. Therapy splinting The treatment is carried out with a dorsal splint which holds the DIP joint for 6 to 8 weeks in the extension; during this time, the tip must not be bent (for example in the purification of the finger). Fractures involving> 25% of the articular surface or cause a subluxation, require surgical fixation.
