when 60% bone density is lost
so tumour may be present before you can see on xray

MRI more sensitive so will see sooner

Answer 8

bony projections associated with degeneration of cartilage at joints /spine
OA

Question 9

opposite of erosion in bone terms

Answer 9

sclerosis

Answer 10

bowed = varus

knock kneed = valgus

Question 11

crepitus=

eg

Answer 11

crepitations
- grating /cracking/rattling sound/sensation between bone and cartilage in joint

OA

Question 12

Tophaceous

Answer 12

around the joint

long term gout= tophaceous gout

Question 13

Answer 24

removal of dead/ damaged / foregin objects

= athroscopic lavage

Question 25

Answer 42

RA

Question 43

what are the x ray differences between RA and OA

Answer 43

RA = LESS
 Loss of joint space
 Erosion (peri-articular)
 Soft tissue swelling
 Soft bones - osteopenia

OA - LOSS
 Loss of joint space
 Osteophytes (bony growths)
 Subchondral sclerosis
 Subchondral cysts

Question 44

what does bone pain (rather than joint pain) indicate

Answer 44

tumour
infection
fracture

Question 45

Answer 45

fibrous capsule

Question 46

Answer 46

syndesmosis = immovable joint where bones are joined together

A- below syndesmosis
B - at point of syndesmosis
C - above syndesmosis

Question 47

Answer 47

SITS
supraspinatus
infraspinatus
teres minor
subscapularis

Question 48

total vs hemi joint replacement

• material
• pro of each

Answer 48

total = metal+metal
last longer

hemi = bone + metal
less long - but less sternous surgery for patient

complications of fractures

Answer 49

LOCAL
surrounding damage - nerves, organs, vasculature

compartment syndrome - increased pressure effects nerves, vessels

infection/contamination- open wound/surgery
