b. Open (compound) fracture

29
Q

break that does not penetrate the skin

A

Closed (simple) fracture

30
Q

broken bone penetrates through the skin

A

Open (compound) fracture

31
Q

Common types of fractures

A
  • Comminuted
  • Compression

  • Impacted
  • Spiral
  • Greenstick
32
Q

bone breaks into many fragments

  • particularly common in the aged (whose bones are more brittle)
A

Comminuted

33
Q

bone is crushed

  • common in porous bones
A

Compression

34
Q

a type of fracture where broken bone portion is pressed inward

-typical of a skull fracture

A

Depressed

35
Q

a type of fracture where broken bone ends are forced into each other

  • when one attempts to break a fall with outstretched arms
A

Impacted

36
Q

a type of fracture where ragged break occurs when excessive twisting forces are applied to a bone

  • common sport fracture
A

Spiral

37
Q

a type of fracture where bone breaks incompletely, much in the way a green adults

  • common in children (bones are more flexible)
A

Greenstick

38
Q

Stages in the healing of bone fracture

A
  1. Hematoma formation
  2. Fibrocartilage callus formation

  4. Bone remodeling
39
Q

Effects of Growth hormones in bones

A
  • Hyposecretion
  • Hypersecretion
40
Q

Hyposecretion/removal of pituitary gland

A

results in premature cessation of transformation of chondrocytes to bones in epiphysis

Hypersecretion

A

giantism/acromegaly

42
Q

Effects of Parathormone in bones

A

Overactivity

43
Q

Effects of Thyroxine in bones

A
  • Defiency in young- delayed/incomplete ossification causes softer bones
44
