Measuring for Willowwood Alpha Classic BK prosthetic liner.

STEP 2: Find your size

Take your top and bottom measurements and use the chart to determine your size. If you're in-between sizes, we suggest remeasuring again to be on the safe side. If the size you arrived at after measuring seems too big or small, in some cases it helps to use the size of your current liner as a very rough guide. The size may be printed on the liner or you can contact our team and provide the serial number printed on the side. Continue to STEP 3: Length

When measuring your thigh, pay special attention to how tight you take your measurement. It's best to pull the ends of your tape measure somewhat tight and then release. Your goal is to find a middle ground of how much tension you should apply to your measuring tape. Too tight and too loose will both result in a poorly fitting prosthetic liner.

WillowWood Alpha Hybrid Liner Description

The Alpha Hybrid Liner is formulated with Willowwood's Hybrid Gel, allowing prosthesis users to experience the performance of silicone along with the comfort of gel. Covered with a one-way stretch outer fabric that controls pistoning by allowing circumferential stretch yet maintaining elongation within limits. Below-knee versions incorporate an abrasion resistant front panel that promotes easier knee flexion without experiencing pulling or tightening over your knee cap. The Symmetrical profile of the above knee version allows the Hybrid liner to be rotated, increasing the lifespan of your liner. The Alpha Hybrid Liner is a solution for amputees currently wearing an Alpha Classic and are seeking an upgrade.

Read our Prosthetic Liner Guide for more information on prosthetic liners.

Features & Details

WillowWood Alpha Hybrid Prosthetic Liner Materials

Thermoplastic Elastomer (TPE) material

Directions for Use

Prior to applying your Alpha Hybrid Liner make sure your residual limb is clean, dry, and free of any soap residue. Cover any open wounds and non-intact skin with a product similar to Spenco. WillowWood states to avoid using any type of animal based lotions or powders on your residual limb or liner. These products may damage your WillowWood Liner.

Invert your WillowWood liner so that the logo is on the inside. Place the end of your liner against the end of your limb. If using a pin lock liner, center the pin attachment on the bottom of your limb. Pay special attention when using the AK version to have the logo positioned along the outside. Carefully roll your liner onto your limb.

***Warning: Do not pull your liner onto your limb. Pulling the liner may stretch the skin and result in an uncomfortable fit and possible skin issues along the edge of your liner. Last, make sure that there are no wrinkles or air pockets between the liner and your limb. Air pockets cause excessive sweating.

Care Instructions

Proper hygiene is critical when wearing any prosthetic liner. Your Alpha Hybrid Liner must be thoroughly cleaned each day and disinfected once a week. Clean the gel side of your Hybrid liner using lukewarm water and a pH balanced prosthetic cleanser. Apply your prosthetic cleanser with a clean, soft cloth or sponge.

**Warning: Do not scrub your liner on either the fabric or gel sides.

Rinse your Alpha Gel Liner with water and dry it with a clean and lint-free cloth. Place your Hybrid Liner on a drying stand with the logo on the outside.

Once a week spray the gel side of your liner with ethyl alcohol spray and wipe clean with a lint-free soft cloth. Last, rinse any alcohol from your liner with water and dry again using the above instructions.

Precautions

Do not place your WillowWood Alpha Hybrid Liner on an open wound. If irritation, discomfort or poor circulation occurs, discontinue use and notify your physician or Prosthetist immediately. Do not wear an Alpha Hybrid for more than 20 hours daily.

This Alpha Hybrid Liner is not indicated for any amputee who has a skin condition which can be aggravated when covered by a non-porous gel material. The Alpha AK Liner should not be used by any prosthesis user whose residual limb is shorter than 3 inches, unless a secondary AK Belt is used.
