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
