Alps Extreme HD Liner
Recommended for patients with moderate to high activity levels, as it provides a high level of prosthetic control while maintaining comfort. It is also recommended for patients with excess soft tissue on the stump and for patients with above-knee amputations.
The ALPS Extreme™ HD Denture Liner provides patient comfort and control of the prosthesis.
HD Gel relieves vertical and lateral loads on the residual limb; at the same time, it makes the liner more compact.
Fabric with limited vertical elasticity also limits the vertical oscillation effect.
This makes it the ideal liner for the most active users who need maximum control of their prosthetic leg without sacrificing comfort.
PECULIARITIES:
- Reduces the effect of vibration due to limited vertical elasticity of the tissue and the distal matrix (lock version)
- Minimises soft tissue movement and provides a high level of prosthetic leg control by combining the properties of High Density Gel with the limited elasticity of vertical tissue.
- Protects the residual limb due to HD Gel's high ability to absorb vertical and shear forces
