is a Rehab Indy service to help inform our patients and other amputees about prosthetic components and services. As Practioners; performing the same tasks over the years, sometimes we overlook that not everyone is familiar with every aspect of prosthetics. That is why we have installed this forum called Tech Tip. Through the next several months we will be covering different areas of prosthetics that are important to you; the amputee, but areas we sometimes take for granted. If you have a Tech Tip idea contact : customerservice@rehabindy.com and we will detail that phase of prosthetics.

This month's featured topic is:

Gel-liners

One of the most diverse components in design and construction available to the amputee is the gel-liner. A gel-liner is the soft interface commonly used between the residual limb and the prosthesis. Fabricated from a variety of different materials such as urethane, silicone, or thermoplastic elastomers, a gel liner helps cushion the residual limb. To help protect the skin and reduce irratation, several manufacturers have added aloe vera, mineral oil, vaseline, and vitamin E into their prosthetic liners. The most important aspect of a gel-liner to the wearer, is the proper donning of the liner.
: To properly don a gel liner, first roll the liner inside out. Next place the liner cupped to the distal (end) of the residual limb, then gently roll the liner into place. Do not try to pull on the liner as this may cause excessive tension on the skin and soft tissue, resulting in an uncomfortable fit. Then add any socks if needed over the gel-liner for a proper fit.

Gel-liners may also be incorporated into the suspension of the prosthesis. The photo-
graphs below show three of the most common ways to suspend a prosthesis with a gel-liner. Photo A: a cushion liner, usually worn in conjunction with a knee sleeve and suction. Photo B: a locking liner, with an added pin this liner slides into a locking mechanism fabricated in the prosthesis. Photo C: a seal-on liner, spray the membrane with a water and alcohol mix, then don the prosthesis, air is pushed out thru an expulsion valve to create suction.

A few helpful tips about gel-liners. As with any component that makes skin contact hygene is very important. Wash the gel-liner daily with a skin friendly soap and throughly rinse with water. Most skin irratations found with wearing a liner can be traced back to this lack of attention. Also when possible use two liners and rotate them every other day.
