A South Carolina Amputee’s Guide to Prosthetic Liners, Sleeves, Socks, and Shrinkers.

For those new to prosthetics or orthotics, the number of unfamiliar terms can seem overwhelming. To assist you and those searching for prosthetic and orthotic supplies near Conway, Myrtle Beach, and Loris (and throughout Horry and Georgetown counties, too.), we’ve created a brief overview of each, along with their differences and how each can enhance your overall quality of life.

A prosthetic liner is a prosthetic product used to provide cushioning and protection for an amputee’s residual limb and the prosthetic socket.

TPE Liners (Thermoplastic Elastomer)

Ideal for sensitive or new amputees and those seeking comfort. Its softness has some drawbacks, such as the gels holding the liner together being less durable.

Silicone Gel Liners

These balance softness and durability, providing more endurance than TPE liners, while still being relatively soft; suitable for those who are more active and require greater durability in prosthetic supplies.

Urethane Liners

The least soft of the three types, has excellent flow properties, allowing the gel to distribute pressure evenly for a better fit; its material is considered to be the closest to skin. These liners are often used with vacuum sockets for superior suspension, they are suitable for high-activity wearers who require durability and adaptability. 

There are various advanced prosthetic liner technology options, and their application varies by your unique amputation type (above knee, below knee, upper extremity); it is best to consult with your prosthetist to determine your best liner option. At Lyons Prosthetics & Orthotics patients often ask for the Seal-In® X Locking Liner System; we are providing a bit more detail on this model below:

Iceross Seal-In® X Locking Liner System

The Iceross Seal-In X Locking is a silicone liner suitable for transtibial amputees of all activity levels. It provides exceptional functionality by merging the advantages of locking suspension with those of Seal-In. The liner comes in two profiles: 3mm and 6mm. It is recommended to use this liner with the Icelock 562 Hybrid for optimal results.

Liners play a crucial role in providing appropriate suspension and forming the foundation of a comfortable and effective prosthetic. Even the most technologically advanced prosthesis requires the right liner solution to ensure a proper fit, optimal function, and maximum comfort. The Iceross Seal-In X Locking Liner is designed for trans-tibial locking liner users of all activity levels, providing enhanced functionality by combining the advantages of locking suspension with those of vacuum suspension. This allows users of locking suspension systems to benefit from reduced pistoning and improved rotational control, in addition to the perceivable feedback of the mechanical connection that they have come to trust.

Secure Suspension

Secure suspension refers to the ability of a prosthetic system to hold the residual limb in place within the socket, reducing any unnecessary movement. This is crucial as excessive movement can cause discomfort and pain to the amputee. Moreover, it increases the risk of skin ulcers due to repeated friction and pressure on certain areas of the skin. By ensuring secure suspension, the risk of such complications is greatly reduced, and the amputee can enjoy greater comfort and confidence in their daily activities.

Reduced Pistoning

Seal-In liners are a type of liner used in prosthetic systems to create a seal around the residual limb, improving suspension and reducing movement within the socket. One key benefit of Seal-In liners is their ability to significantly reduce pistoning, which is the up-and-down movement of the residual limb within the socket. Research has shown that Seal-In liners can reduce pistoning up to 71% compared to a locking liner. This reduction in pistoning can greatly enhance the comfort and function of the prosthetic system, as it minimizes the risk of skin irritation and discomfort caused by excessive movement. As a result, amputees can enjoy greater stability and confidence in their daily activities.

Improved Rotational Control with Seal-In

Skin irritation may occur due to rotation within the socket. However, the use of Seal-In liners can provide better rotational control as compared to silicone liners equipped with a shuttle lock and a PU liner, as per reference.

Prosthetists use sleeve suspension as a method to create a secure connection between you and your prosthesis. Typically, suspension sleeves are intended for individuals with Below Knee or Below Elbow amputations. They are typically rolled onto the user’s thigh or upper arm and utilize vacuum, suction, and/or compression for suspension; and, can be made of knitted fabrics, gels (polyurethane, copolymer, silicone), or neoprene. Sleeves can also be used in conjunction with other systems, such as prosthetic cushion liners and Suction or Vacuum Systems as described above.

A prosthetic stump sock is an essential component of almost all prosthetic systems. It is designed to fit snugly over your residual limb, providing cushioning and helping to manage any residual limb size and shape changes throughout the day (due to fluid changes such as perspiration). It is crucial to have a well-fitted prosthesis as a loose one can be uncomfortable, cause friction blisters, and may even lead to ulcers. Therefore, a prosthetic stump sock plays a crucial role in ensuring a comfortable and safe experience for amputees and their advanced prosthetic limbs.

A shrinker is a type of elastic sock designed to control swelling, promote healing, and aid in shaping the amputated leg. This facilitates a more consistent fit of your prosthesis (artificial limb), ensuring greater comfort and functionality.

For new amputees, when your limb is ready and the healing of the incision has progressed significantly, it will be time to start using a shrinker. It is recommended to wear the shrinker during nighttime and whenever you are not using your prosthesis. In the absence of the prosthesis, the shrinker should be worn continuously throughout the day and night.
