1

ARTHRODESIS

the surgical fixation of a joint to produce an artificial bony union

2

AMPHIARTHRODIAL JOINT

partially movable joint

3

SYNARTHRODIAL JOINT

immovable joint

4

ARTICULATION

a joint

5

SEPTUM

any partition separating two cavities or masses

6

FOSSA

a depression

7

FORAMEN

a hole in a bone, a normal passage, usually into or through a bone

8

FISSURE

a narrow slit

9

TUBEROSITY

large rounded process

10

TUBERCLE

smaller rounded process

11

TROCHANTER

very large rounded process

12

SPINE

sharp slender process

13

CONDYLE

rounded, knoblike projection

14

CREST

a narrow ridge or bone

15

DIAPHYSIS

shaft of a bone

16

EPIPHYSIS


end of bone (long bone) - separated from shaft by cartilage until growth is complete - provides for growth in length

17

EPIPHYSEAL LINE

layer of cartilage between diaphysis and epiphysis

18

METAPHYSIS

part of diaphysis next to an epiphyseal line

19

BREGMA

junction of coronal and sagittal sutures

20

INION

external occipital protuberance of the skull

21

FONTANEL

an unossified spot on the cranium of an infant (soft spot)

22

LAMBDA

junction of sagittal and lambdoidal sutures

23

SUTURE

the line of union in an immovable articulation

24

SACRALIZATION

last lumbar vertebra is partly or completely fused with first segment of the sacrum

25

SPONDYLOLISTHESIS

the forward displacement of one vertebra upon the upper surface of the vertebra beneath it - usually occurs at the lumbosacral joint

26

KYPHOTIC CURVE

a curvature of the spine backward, concave curve, normal in thoracic and sacral regions

27

VERTEX

the top of the head

28

*SPINA BIFIDA

laminae of a vertebra may fail to unite with each other in the midline posteriorly. Vertebral arch will be incomplete, spinal cord may herniate out through this defect

29

*SCOLIOSIS

abnormal lateral curvature of the spine

30

LORDOTIC CURVE

a curvature of the spine forward, convex, normal in the cervical and lumbar regions

31

NONUNION

failure of the ends of a fracture to heal and unite

32

PATHOLOGIC

one which is due to disease

33

*COMPRESSION

fracture caused by pressure

34

POTTS

fracture to the distal end of fibula with dislocation of foot outward and backward

35

IMPACTED

break where one bone fragment is pushed or driven into another

36

*COMPOUND

where bone is broken and extends to the outside

37

COLLES

a transverse fracture of the distal end of the radius with displacement of the hand backward and outward

38

*OVERRIDING

the slipping of either part of a fractured bone past the other

39

*DEPRESSED

a portion of the bone is driven inward as in the skull

40

*SPIRAL

fracture line extends obliquely along the shaft of bone

41

*GREENSTICK

bone is partially bent and partially broken

42

*COMMINUTED

bone is broken with two or more fracture lines
