Build bone

Question 2

Osteoclast

Answer 2

Breaks down bone

Question 3

Osteocytes

Answer 3

(Cell within the bone)

Keeps bone healthy

Question 4

Collagen

Answer 4

Gives it flexible strength (so it can bend)

Question 5

Question 6

Endochondral ossification

Answer 6

The process of turning cartilage into bone

Question 7

Stimulates the production of new blood vessels into healing bone tissue

Answer 7

Histamines

Question 8

Open/ compound

Answer 8

Bone breaks and sticks through skin

Question 9

Complete V incomplete (greenstick)

Answer 9

Incomplete= not all the way through usually only in children

Question 10

Transverse fracture

Answer 10

Break forms a right angle with the axis of the bone (straight across break)

Question 11

Oblique fracture

Answer 11

Line of break runs at a slanted angle (but breaks all the way through)

Question 12

Avulsion fracture

Answer 12

Tendon or ligament pulls a small chip of bone away from the rest of the bone

Question 13

Impacted fracture

Answer 13

When the narrow part of bone is pushed up into the wide part of the bone

Question 14

Depression fracture

Answer 14

Caves in

Question 15

Comminuted fracture

Answer 15

Breaks into 3+ pieces

Question 16

When describing long bone don’t forget to put
angulation (valgus, radial, dorsal, etc.) if bone touching a little

Displacement: (medial/ lateral, if bone is not touching at all)

Answer 16

L

Question 17

Signs of Fx (5)

Answer 17

• swelling
• pain
• deformity
• point tenderness
• discoloration

*super painful at first then is just full aching pain

Question 18

Treatment of fracture

Answer 18

• it will remodel itself
• rest
• Reduction (put bone in proper position)
• cast/taping
• internal fixation (surgery)

Question 19

Healing:

1. Nonunion
2. Malunion

Answer 19

1. Nonunion (non-healing): pieces not close enough so they form 2 bones
2. Malunion: it has healed but the bony calius has made it into 1 bone

Question 20

A solid swelling of clotted blood shotgun the tissue (like the ear thing, or yellow bruise)

Question 27

3 stages of soft tissue repair

Answer 27

• bleeding*
  1. Inflammation (4-6 days)
  2. Proliferation (producing scar tissue) (granulation=fibroblast, fill the wound/ contraction/ epithelialization= reproduce and heal top of skin)
  3. Remodeling=
