System Conditions
        Definition
A skeletal joint is a point at
 which two bones meet. This is
 sometimes called an
 articulation.

The Types of Joints            4



1.   Ball and Socket           2
2.   Gliding
                       5
3.   Hinge
4.   Immovable
5.   Pivot

         Structures of Joints
   A Joint is composed of two bones. Thin
    membranes called Hyline or Articular
    cartilage cover the ends of some bones.
    Other bones are cushioned with layers of
    pads of cartilage. Strong fibrous bands,
    which are flexible, bind the bones together.
    These bands are called ligaments.
    Ligaments join with other connective tissue to
    form a sheath, or capsule, enclosing the
    moveable joints. The joint capsule is lined
    with a membrane that secretes synovial
    fluid, which acts as a lubricating substance.
    Special Conditions Related
      to the Skeletal System
   Ruptured Disc-
    The cartilage
    between the
    vertebrae have
    soft, jelly-like
    centers. Under
    stressful back
    movements, the
    disc may rupture
    and the jelly-like
    centers push on
    the spinal nerve
    causing severe
    pain and
    numbness.
    Special Conditions Related
      to the Skeletal System
   Osteoporosis- A
    Metabolic disorder         Normal
                                bone
    where the bones            density
    lose minerals and
    become brittle.

                         osteoporosis
    Special Conditions Related
      to the Skeletal System
   Scoliosis- A
    lateral curvature
    of the spine. “S”
    shaped curve.
    Special Conditions Related
      to the Skeletal System
   Fractures- A break
    in the bone.

    Fracture=Break
        Fractures
       Types of Fractures
1.   Closed (simple)- the skin has not
     been broken
2.   Open (compound)- the overlaying
     skin is broken.
3.   Greenstick- the bones stay together
     Symptoms of
      Fractures
Sometimes   Bruising
 no                   to
             Inability
 symptoms     move body
Swelling     part
PAIN        Grating
Deformity   Exposed
              fragments
    Special Conditions Related
      to the Skeletal System
   Sprains- An injury to a LIGAMENT.
         Sprains
     Types of
      Sprains
1. Mild-
   overstretched
   ligament
2. Moderate- partial
   tear in the
   ligament
3. Severe- Complete
   tear in the
Symptoms of Sprains
    Swelling
    Tenderness
    Pain  in motion
    Bruising
    Joint laxity
    Special Conditions Related
      to the Skeletal System
   Strains- Injury to a
    MUSCLE/TENDON
 Symptoms of Strains
Swelling
Tenderness
PAIN
Bruising
Deformity    Notice depression at site of rupture (red circle).
Special Conditions Related
  to the Skeletal System
   Dislocation- Displacement of the bone.
    When the joint is pushed beyond its
    normal range of motion.
       Symptoms of
       Dislocations
 Deformity   of the joint
 Severe pain
 Swelling around the joint
 Bruising
 Inability to move the injured
  area
Special Conditions Related
  to the Skeletal System
   Bursitis-
    Inflammation of
    the capsule/sac
    near the joint.
Special Conditions Related
  to the Skeletal System
   Tendonitis-
    Inflammation
    of the tendon
    Special Conditions Related
      to the Skeletal System
   Arthritis- Inflammation in and around the
    joint
       First Aid for Soft
        Tissue Injuries
R     REST- no weight barring activities


I     ICE- ice for 24 to 48 hours. 20 min. on/ 20 min. off


C     COMPRESSION- wrap it snug, but not too tight


E     ELEVATION- keep the injury elevated; level with
the
      heart
