Our recommendation

Otto Bock offers three different liner materials, each of which has different characteristics recommending a corresponding closure system for each material.

For the best possible fitting results, we recommend the combinations of liners and closure system listed in the table.

Otto Bock offers three different liner materials, each of which has different characteristics (columns 1 and 2). We recommend a corresponding closure system for each material (column 4). However, the best combination needs to be individually selected for each patient.

The SiliconGel-Liner 6Y75 with SkinGuard Technology® from Otto Bock.

Silicone liner

For example, silicone is very durable and easy to clean. It is ideal for patients with a low to moderate degree of activity and residual limbs that have good soft tissue coverage. In addition, a specific weight bearing socket should be used.

With a silicone liner, the best possible fitting is achieved in combination with a shuttle lock.

The Balance TPE Liner 6Y93 from Otto Bock.

Copolymer liner

Copolymer is a user and prosthetist-friendly material that offers good protection against the forces acting in the socket. It is suitable for many residual limb types, especially residual limbs with dry skin.

With this material, the best possible fitting is achieved in combination with a valve.

The Simplicity Tapered-Liner 6Y522/ 6Y523 from Otto Bock.

Polyurethane liner

The yielding effect of polyurethane ensures even pressure distribution, making it suitable for all residual limb types including sensitive, bony and/ or scarred residual limbs. A full-contact socket according to the Harmony® principle should be used in this case.

With polyurethane, the best possible fitting is achieved in combination with a valve or the Harmony® system.

For the best possible fitting results, we recommend the following liner / closure system combinations:

Material	Characteristics	Indications	Ideally used with
Silicone	Very durable Easy to clean	Residual limbs with good soft tissue coverage Low to moderate activity level Used with a specific weight bearing socket	Shuttle lock
Polyurethane	Yielding effect of the material ensures even pressure distribution	All residual limb types; especially sensitive, bony and/ or scarred residual limbs Low to high activity level Used with full-contact socket according to the Harmony® principle	Valve or Harmony® system
Copolymer	User-friendly and prosthetist-friendly Offers good protection against socket forces	Many residual limb types; especially residual limbs with dry skin Low to moderate activity level Used with a full-contact socket	Valve

Please note that the specified combinations of liner materials and closure systems constitute general recommendations. Actual fittings are always customised to you and your needs. Please consult your prosthetist if you are interested in Socket Technologies.
