Alpha DESIGN® BK Liners


Custom Alpha DESIGN BK Liners are created by practitioners to provide amputees maximum comfort. Amputees with uniquely-shaped residual limbs or residual limbs that are bony, short or invaginated are perfect candidates for Alpha DESIGN BK Liners. When creating an Alpha DESIGN Liner from OMEGA® Tracer®, prosthetists can adjust the gel thickness from 3 mm, such as behind the knee, to 3 mm thickness at the proximal point of the liner, to 25 mm over invaginations on the residual limb. Gel pads up to 12 mm thickness can also be applied where needed throughout the liner.

The custom fit offered in an Alpha DESIGN BK Liner finally allows amputees with less-optimally shaped residual limbs comfort while wearing their prostheses. A new socket should be fabricated, according to instructions, for the best performance of an Alpha DESIGN BK Liner. DESIGN Liners created from casts with electronic order forms will be slightly less detailed. Click here for an order form.
