1

What does degenerative arthritis mean?

a condition of degeneration of the joint, sometimes referred to as degenerative joint disease (DJD)

2

What is the age and surface bias associated with degenerative arthritis of the sacra-iliac joint?

age 40, the iliac auricular surface

3

What does ankylosis mean?

a condition of fibrous adhesion occurs within the joint

4

What is the age and gender bias associated with ankylosis of the sacra-iliac joint?

age 50 and male bias particularly in African American males

5

Which is the strongest of the sacro-iliac ligaments?

the interosseous sacro-iliac ligament

6

What is the age and gender bias associated with ossification of the anterior sacra-iliac ligament?

age 40 and male bias

7

What are the attachment sites of the interosseous sacroiliac ligament?

at the sacral tuberosity and the iliac sulcus

8

What passes between the layers of the interosseous sacra-iliac ligament?

dorsal rami from the sacral spinal nerves

9

What is formed by the continuation of the sacrotuberous ligament along the ischial ramus?

the falciform process

10

What separates the greater sciatic and lesser sciatic foramina?

the sacrospinous ligament

11

Primary centers of ossification for the sternum first appear at what age?

fifth fetal month

12

Syncondroses of the corpus stern will fuse together beginning with which sterna brae?

the lower sternabrae fuse first; they ossify in a caudal to cranial direction

13

What vertebral levels correspond to the position of the manubrium sterni?

T3-T4

14

What vertebral levels correspond to the position of the corpus stern?

T5-T9

15

How many sterna brae for the corpus sterni?

4 sternabrae

16

What surface feature on the corpus stern identifies the location of the synchondroses?

transverse lines

17

What articular sites for the costal cartilage of ribs will be identified on the corpus sterni?

costal notches II-VII

18

What feature of the corpus sterni is present in 4-7% of the population

a sternal foramen

19

What causes the appearance of the sternal foramen?

failure of the ossification centers of the sternum to fuse together normally

20

In what part of the rib will primary centers of ossification appear?

the body (corpus, shaft)

21

In what parts of the rib will secondary centers of ossification appear?

the head, articular surface of the tubercle and the non-articular surface of the tubercle

22

When do primary centers of ossification appear in the rib?

during the second fetal month

23

When do secondary centers of ossification appear in the rib?

during puberty

24

Which ribs will demonstrate primary centers of ossification for the body (corpus or shaft)?

all ribs; ribs 1-12

25

Which ribs will demonstrate secondary centers of ossification?

ribs 1-10

26

Which ribs lack secondary centers ossification?

ribs 11 and 12
