1

difference bw osteoperosis and osteomalacia

osteoperosis-normal bone just less of it

Osteomalacia- abnormal bone

2

3 presentations of osteoporosis

1. Generalized (primary or secondary
2. Regional (disuse, CRPS, transient)
3. Localized (secondary)

3

What age is associated w generalized osteoperosis

-After age 35
-Post enopausal women 50-65

4

What age is peak bone mass

30

5

ratio of women and men who have osteoporosis

1 in 4 women
1 in 8 men

6

Primary conditions that cause osteoperosis in younger indvs

-Osteogenesis Imperfecta
-Marfans syndrome

7

Plain film signs of osteoperosis (5)

- increased radioluceny of bone
- Thin cortices (<1/2 of mid shaft diameter)
-Accentuation of weight bearing trabeculae
-possible compression fxs
-Reinforcement lines (in severe forms)

8

New compression fx findings (3)

-zone of sclerosis
-step defect
-ant wedging

9

Common cause of compression fxs @ T5 and above

Grand mal seizures

10

What is the look of codfish vertebrea and cause

-Sig lucency in vert body
-vert lines in vert body (multiple lvls)

--generalized osteoperosis

11

Secondary causes associated with osteoperosis

-malignancy
-steroid induced
-cushings disease
-diabetes
-hyperthyroidism, parathyroidism
-thalassemia major

12

What is wards triangle and what will happen

lucent area in femoral neck bw trabeluclations
-will increase in size as osteoporosis develops

13

What is the least sensitive and gold standard for bone density imaging

radiography- least sensitive (useful initially tho)

Bone density- DEXA gold standard

14

What is the T and Z score

T- persons bone density compared to the average

Z- persons bone density compared to an individual of the same age/gender

15

What are the sig T scores

o- -1= normal
-1- -2.5= osteopenia
below -2.5= osteoperosis

16

tx of osteoperosis

Calcium and vit D
Resistence/weight bearing exercises
meds: bisphosphonates, calcitonin, parathyroid hormone
Surg: vertebroplasty
