									    Dislocations - Closed Articular Injuries


    Dislocations - is closed joint injury in which the articular surfaces of the bones lose their
    normal ratio partially (subluxation) or completely (complete dislocation)
      Location is the displacement of the two ends of the bones results in loss of normal joint contact of the
    two joint surfaces. A sprain is caused by shock or forced displacement, more often than dislocation or
    subluxation anomaliey.Chastichny happens when displaced bone slid to the side, but still remains in
    contact with the surface of the second bone of the joint. In dislocation traumatic incident causing rupture
    of the joint capsule (capsule that provides joint stability) and the two bones that have no connection, one
    of the bones in place of salt violations occurred in the capsule. The first orthopedic intervention
    rapid deployment, it must restore the bone surface in contact, followed by immobilization of the joint.
 Classification of dislocation
 A. On the degree of displacement segment targeted by a dislocation :
    1. complete dislocation
    2. A partial dislocation
    B. By origin of dislocation :
    1. Congenital
    2. Pathological (ligament damage, muscle damage, arthritis, tuberculosis, tumors)
    3. Traumatic (isolated dislocation, without dr.povrezhdeny, fracture-dislocation, dislocation complicated
     with vascular damage of the peripheral nerves, etc.)
    C. For the duration of posttraumatic to recovery :
    1. fresh (up to 3 days)
    2. stale (up to 3 weeks)
    3. chronic (late - more than 3 weeks)
    Causes of   traumatic dislocation
    1. Predisposing factors
    a) anatomical shape of the joint, the degree and the contact area of the articular surfaces and the lower
     the contact zone the easier it is dislocated.
    b) the amount and degree of joint movement, the more range of motion, the easier it can be exceeded.
    c) strength, development agencies capsule and ligaments, muscles, which normally stabilize the joint.
    2. The decisive reason for this is straight (rarely) and indirect (often) injury.
    Clinical symptoms of dislocation :
    Complaints - At the time of dislocation occur: Severe pain Full functional impotence.
    Inspection: The deformation of the joint, a forced situation, the change in length,
    Limb, joint swelling, bruising
    Palpation: Changing normal ratio periarticular bone
    Projections.
    Treatment of dislocation :
    1. First aid
       a) administration of analgesics to reduce pain
      b) immobilization using standard or improvised tools
      c) rapid transport of patients to specialized tutoring
    2. Reduction of dislocation (orthopedic or surgical - chronic sprains, recurrent dislocation or fracture-
    dislocation)
    3. Immobilization of the injured segment
    4. Restoration of function
    Late complications
    Aseptic necrosis of bone
    Limitation of joint movement
    Periarticular calcification
   Articular instability or recurrent dislocation
   Osteoarthritis and periarthritis

   Arthrosis
