Which option describes the residual limb shrinker approach?

• A. Residual limb shrinkers
• B. A series of shrinkers are worn as the limb reduces in size; smaller socks are used over time; socks must be dry and wrinkle free to avoid pressure sores
• C. Wrapping with an elastic bandage is the most frequently used shrinkage method
• D. A cast is made over the end of the residual limb to ensure control of swelling and provide comfort

Answer: (B)

The shrinker approach uses progressive, uniform compression to reduce the residual limb’s volume and shape it for a comfortable, functional prosthetic fit. A shrinker sleeve or sock is worn on the residual limb, and as swelling subsides, you move to smaller shrinkers or thinner socks in a planned sequence. Keeping each shrinker dry and wrinkle-free is essential because wrinkles or moisture can create concentrated pressure points that risk skin breakdown or ulcers. This method promotes a smooth, tapered contour that socket prostheses can seal against more effectively, improving control and comfort during use.

Other methods exist, like wrapping with an elastic bandage, which provides compression but is less controlled and requires more careful technique to avoid uneven pressure. Casting is used for measurement or creating a rigid mold, not for ongoing shrinkage and shaping with everyday wear.
