Nondisplaced

bone ends retain their normal position

1

Displaced

bone ends are out of normal alignment

2

Complete

bone is broken all the way through

3

Incomplete

bone is not broken all the way through

4

Linear

the fracture is parallel to the long axis of the bone

5

Transverse

the fracture is perpendicular to the long axis of the bone

6

Open(Compound)

bone ends penetrate the skin

7

Closed(Simple)

bone ends do not penetrate the skin

8

Comminuted

bone fragments into three or more pieces, commonly in the elderly

9

Compression

bone is crushed, common in porous bone

10

Depressed

broken bone portion pressed inward, typical skull fracture

11

Greenstick

incomplete fracture where one side of the bone breaks and the other bends

12

Spiral

ragged break when bone is excessively twisted, commonly in sports

13

Epiphyseal

epiphysis separates from diaphysis along epiphyseal line

14

Bone fractures are classified by

1)Position of the bone ends after fracture
2)Completeness of the break
3)Orientation of the fracture to the long axis of the bone
4)Whether or not the bone ends penetrate the skin

15

Hematoma formation

a mass of clotted blood (hematoma) forms at the fracture site

16

3 structural classes are...

fibrous,cartilaginous, synovial

17

Fibrous

fibrous connective tissue joins bones

18

Cartilaginous

cartilage directly connects bones

19

Synovial

1)bones are separated by a fluid-filled joint cavity
2)all are diarthroses
3)most joints in the body

20

3 functional classes are...

Synarthroses-immovable, amphiarthroses-slightly moveable, diarthroses-freely moveable

21

Sutures

b/n skull bones, fibrous joints

22

Syndesmoses

a ligament of fibrous connective tissue connects bones, fibrous joints

23

Gomphoses

teeth in their sockets, fibrous joints

24

Synchondroses

hyaline cartilage connects bones, cartilaginous joints

25

Symphyses

fibrocartilage connects bones, cartilaginous joints

26

Articular cartilage(hyaline)

smooth, slippery, cushioning surface on ends of bones

27

Joint (synovial) cavity

filled with a lubricating synovial fluid

28

Articular capsule

1)Fibrous capsule-outer dense irregular connective tissue supports the joint
2)Synovial membrane-inner membrane produces synovial fluid
