Alpha Hybrid® AK Liner

Print

The Alpha Hybrid AK Liner with symmetrical gel style features hybrid gel which has a higher durometer that combines durability with comfort. The liner features 9 mm distal gel thickness and 2.5 mm anterior/posterior gel thickness. The symmetrical design allows the liner to be rotated for extended wear. The liner utilizes one-way stretch fabric for controlled pistoning without a rigid distal matrix and provides tissue compression without uncomfortable pressure on the limb. the locking version features an accordion-style umbrella that blends with a patient’s anatomy for an almost unnoticeable feeling.

For locking liners, WillowWood strongly recommends applying Loc-Tite Removable Threadlocker 242 (or equivalent) to the pin threads prior to installing the pin. Failure to ensure that the locking pin is secure in the Locking Liner could result in the pin coming out of the liner, resulting in the potential for injury to the amputee.
