• soft tissue support
• limits edema
• able to use an IPOP

Question 3

Rigid post-operative dressings: disadvantages

Answer 3

• immediate wound inspection not possible
• doesn’t allow for daily dressing changes

Answer 5

Not for ambulatory purposes

Question 6

Semi-rigid dressings: advantages

Answer 6

• reduces post-op edema
• soft tissue support
• allows for earlier ambulation
• protects
• easily changeable

Question 7

Semi-rigid dressings: disadvantages

Answer 7

• doesn’t protect as well as rigid dressing
• requires more changing than rigid dressing
• may loosen and allow development of edema

Question 8

Soft dressings: advantages

Answer 8

• reduces post-op edema
• provides some protection
• inexpensive
• easily removed for wound inspection
• allows active joint ROM

Question 9

Soft dressings: disadvantages

Answer 9

• tissue healing interrupted by frequent dressing changes
• joint ROM may delay healing of incision
• less control of residual limb pain
• can’t control amount of tension in bandage
• risk of tourniquet effect
• shrinker can’t be applied until sutures/staples are removed
