1
Q

Nondisplaced fracture is

A

bone retains in the their normal position

2
Q

Displaced fracture is

A

Bone ends are out of their alignment

3
Q

Open fracture is

A

End of bone penetrates the skin

4
Q

Closed fracture is

A

End of bone does not penetrate the skin

5
Q

complete fracture is

A

bone is broken through the fracture

6
Q

Incomplete fracture is

A

Bone is not broken through the fracture

7
Q

Comminuted fracture is

A

bone fragments into three or more pieces

8
Q

Compression fracture is

A

Bone is crushed

9
Q

Spiral fracture is

A

Ragged break occurs when excessive twisting forces are applied to a bone, common in sports fracture

10
Q

Epiphyseal fracture is

A

Epiphysis separates from the diaphysis along the epiphyseal plate

11
Q

Depressed fracture is

A

broken bone portion is pressed inward, typical skull fracture

12
Q

Greenstick fracture is

A

Bone breaks incompletely, common is children

13
Q

first step to bone repair includes

A
  1. hematoma forms
    - hemorrage (torn blood vessels)
    - clot forms
    - swollen, inflamed and painful
14
Q

2nd Step to bone repair includes

A
  1. Fibrocartilagenous callus forms
    - phagocytes clear debris
    - osteoblast begin forming spongy bone
    - fibroblast secrete collage
    - fibrocartilaginous callus
15
Q

3rd Step to bone repair includes

A
  1. Bony callus formation

- hard callus

16
Q

4th Step to bone repair includes

A
  1. bone remodeling

- resembles original but not completely

17
Q

osteomalacia (adults) and rickets

A

are bones that are soft and weak due to lack of vitamin D and insufficient dietary calcium

18
Q

Osteomyelitis is

A

bacterial infection due to open structures

19
Q

Osteoporosis is

A

loss of bone mass, porous, bone resorption outspaces deposits, due to lack of estrogen, vitamin D

20
Q

Paget’s disease is

A

excessive and haphazard deposit and resorptions, more spongy bone than compact bone, it is caused by a virus
