1

What are the 3 reasons regional osteoperosis can occur

1. Disuse/immobilization osteoperosis

2. CRPS

3. Transient regional osteoperosis

2

Characteristics/age/timeline of transient osteoperosis of the hip

-sudden, reversible, idiopathic (may be associated w pregnancy in females)

-20-40 yoa, M>F

-self limiting 3-12 months

3

Transient osteoporosis of the hip: symptoms and management

Symptoms: pain, antalgic limp, risk of fx

Management: no force in region, reduce weight bearing, self limiting 3-12m

4

CRPS age

>50 yoa

5

CRPS mc sites

Distal to site of injury
-hand/shoulder

6

CRPS etiology and clinical pres

Follows minor trauma/ immobilization (3-6m post)
-believed to be due to over activity of sympathetic n system resulting in trophic changes to bone/soft tis

--acute onset of painful regional osteoperosis

7

Non specific clinical findings of CRPS

-hyperalgesia
-vasomotor abnormalities
-variable skin changes
- edema often present

8

CRPS imaging findings (3)

-patchy osteopenia (peri articular)
-soft tissue swelling
-sub periosteal bone resorption

9

Stage 1 of CRPS- timeline, symptoms

0-3 m
-radiographs usually normal*, may be positive bone scan
-puffy swelling, redness, warmth, decreased ROM
--Aggressive tx best here!

10

Stage 2 of CRPS- timeline, symptoms

3-6m
-osteopenia on radiographs*
-worse pain, edema hardens, cyanosis, dry skin

11

Stage 3 of CRPS- timeline, symptoms

>6-12m
-Severe osteopenia*
-skin pale, cool, pain dimish

12

management of CRPS

meds: corticosteroids, bisphosonates
physical/occupational therapy

13

CRPS prognosis

-if not caught early can spread to entire limb, bone, muscle
-muscle atrophy/functional impairment can be severe

*Early tx essential (remission possible)*
