Alps Anterior Posterior Tapered Liner
Recommended for below-knee amputees with moderate to high activity levels who desire improved prosthetic control and freedom of movement without sacrificing comfort.
The Alps Anterior Posterior Tapered Liner tapers gradually from a thicker anterior portion to a thinner posterior portion, allowing freedom of movement for users with a lower leg amputation. The 6mm thick anterior portion provides a high level of protection for the bony areas. By combining High Density Gel with limited vertical tissue elasticity, this liner minimizes soft tissue movement and reduces the vertical oscillation effect, providing a high level of prosthetic control.
PECULIARITIES:
- Reduces the effect of vibration due to limited vertical elasticity of the tissue and the distal matrix (lock version)
- Protects the residual limb due to HD Gel's high ability to absorb vertical and shear forces
- Protects bone areas thanks to the 6 mm thickness of the front wall.
- Greater freedom of movement thanks to the 3 mm thick back wall.
- Minimises soft tissue movement and provides maximum control of the prosthetic leg by combining the properties of High Density Gel with limited vertical tissue elasticity.
