Q

What is trauma and how does it occur?

A
  1. Physical injury or wound produced by External or Internal force.
  2. Occurs when force is greater than the tissue can withstand.

Q

Acute vs Chronic injury

A
  1. Acute injuries only last for a short period of time. (sudden onset)
  2. Chronic injuries are long term injuries.

Q

What is Hooke’s Law

A
  1. Strain is proportional to the stress producing it (as long as the strain is not too great - once that limit is exceeded, change occurs)

Q

What is Plastic Change?

A
  1. Change in the tissue that lasts after load is removed.
  2. When this occurs over time, it is called creep.

Q

Compression

A
  1. External loads are applied toward on another on opposite sides of the structure.
  2. Shortens and widens the structure.

15
Q

Tension

A
  1. Force that pulls or stretches tissue
16
Q

Shearing

A
  1. Equal load is applied to apposing surfaces forcing those surfaces to move in parallel directions.
17
Q

Bending

A
  1. External force is applied to a joint causing a bend.
18
Q

Torsion

A
  1. Twisting in opposite directions from opposite ends of a structure cause a shear stress over the entire cross section of that structure.
19
Q

Soft tissue vs. Hard tissue

A
  1. Hard tissue: Bone fracture
  2. Soft tissue:
    a. Ligament
    b. Muscle
    c. Cartilage
    d. Bursa
    e. Nerve
20
Q

What are the functions of Bones?

A
  1. Protects organs
  2. Stores minerals
  3. Helps as lever to provide movement to skeletal muscles.
21
Q

What is cortical in the bone?

A
  1. Dense outer surface of skeletal bone.
  2. High resistance to bending and torsion.
22
Q

What is trabecular in the bone?

A
  1. Internal tissue of bone (spongy)
  2. House bone marrow
23
Q

What are the 6 fracture classifications?

A
  1. Greenstick: incomplete break, usually adolescents.
  2. Comminuted: 3 or more fragment sites
  3. Linear: Jumping from a height, line going straight down.
  4. Transverse: Direct blow
  5. Oblique: Torsion or twisting
  6. Spiral: Rotational/twisting force
24
Q

What is the Epiphyseal plate?

A
  1. Growth plate of Bone
  2. Housed on the end of each bone.
  3. Determines the future growth and shape of each bone.
25
Q

Osteoarthritis

A
  1. Degenerative joint disease in which the tissues in the joint break down over time.
26
Q

Ligament

A

Bone to Bone

27
Q

Tendon

A

Muscle to bone

28
Q

Sprain

A

Ligament

29
Q

Strain

A

Muscle or tendon

30
Q

What are the degrees of injury?

A
  1. Grade 1: Stretch, ligament stretched or slightly torn
  2. Grade 2: Partial Tear, Ligaments partially torn
  3. Grade 3: Complete rupture, ligaments completely torn.
31
Q

Hyaline Cartilage location and function

A
  1. Helps bones move smoothly past each other in your joints.
  2. Most common type of cartilage found on joints, ribs, nose, etc.
32
Q

Fibrocartilage location and function

A
  1. Location: Meniscus in knee, discs between vertebrae, supporting muscles, tendon, ligaments.
  2. Function: Consists of tissue that provides smooth surface for articulation and to facilitate transmission of loads with low friction
33
Q

Connective Tissue

A
  1. Found in joints and intervertebral disc, acts as shock absorber.
34
Q

Circumferential Cartilage

A
  1. Present in the form of a ring to improve bony fit
35
Q

Labrum

A
  1. Type of cartilage found in shoulder and hip joint, provides support
36
Q

Bursa (bursitis)

A
  1. Small fluid filled sac that reduce friction between moving parts in joints
