1

Fibers that bind the ends of bones together are called what?

Ligaments

2

FIbers that connect the bones to muscles are called what?

Tendons

3

A sprain is a tearing of what?

Ligaments

4

Primary ossification is nearly complete at birth. T?F?

True

5

Secondary ossification occurs when?

During childbirth.

6

Ends of long bones remain cartilaginous until 20 when skeletal growth is complete. T?F?

Osteoblasts push the end of the bone away from the shaft and lead to calcium deposition in the new bone. T/F?

True, True

7

Fibrous membranes that exist between the cranial bones are called what?

Fontanels

8

What is the purpose of fontanels?

Allows growth of the brain and skull.

9

What are children at risk for fractures?

Long bones are porous and less dense.

10

Muscles increase in # as the child grows. T/F?

FALSE, muscles increase in length and diameter.

11

Muscles reach max diameter in girls at __ years and boys at ___ years.

Girls - 10
Boys - 14

12

Muscle strength continues to increase until __ to ___ years.

25-30. So for those over 30, its all down hill!

13

Growing pains are an old wives tale and have no scientific rationale to explain their existence. T/F?

FALSE - they are due to rapid growth where muscles are pulled as the bone grows too quickly.

14

Leg fractures are the most common. T/F?

FALSE - forearm fractures are the most common.

15

What is a buckle fracture?

Common in young kids - bulging area due to compression. Near the epiphyseal plate.

16

What is a complete fracture?

fracture parts are separated - it's Completely fractured.

17

What is a greenstick fracture?

Due to bone being angled beyond limits.

18

what is a transverse fracture?

at right angle to the bone.

19

What is an oblique fracture?

slanting but straight - perpendicular. Like you're cutting a piece of meat!

20

What is a spiral fracture?

Twisting.

21

Where is the weakest point of long bones?

Epiphyseal plate (growth plate!)

22

What is a type 1 epiphyseal injury?

Common - growth plate undisturbed, growth disturbances rare.

23

What is a type 2 epiphyseal injury?

Most common. Growth disturbances rare. Small break in bone.

24

What is a type 3 epiphyseal injury?

Less common, serious threat to growth and joint. Looks like the joint is cracked away.

25

What is a type 4 epiphyseal injury?

Serious threat to growth. Joint cracked and so is bone.

26

What is a type 5 epiphyseal injury?

Rare, crush injury causes cell death in growth plate, arrested growth and limited bone length. If growth plate is partially destroyed, angular deformities may result. CRUSH.

27

What two factors place the child with a femur fracture at risk for shock?

Blood loss, pain.

28

What are some clinical manifestations of fractures?

Swelling, pain, tenderness, decrease function and use, muscular rigidity, crepitus

29

If a child can walk on his leg, it can't be fractured. T/F?

FALSE

30

What are the 5 P's of vascular injury assessment?

Pain & point of tenderness
Pulse: distal to the fracture site.
Pallor
Paresthesia: sensation distal to the fracture site.
Paralysis: movement distal to the fracture site.
