Elite BladeVT

Suitable for outdoor use
Activity Level 3 4

The Elite BladeVT prosthetic running foot offers powerful performance for high impact, Level 3-4, activities and sports. The blade flexibility combined with the shock absorber and rotation device enhance speed, agility and comfort.

The technology incorporates the proven endolite e-carbon tripod footspring design with an innovative and highly durable titanium axial spring which makes twisting and turning in the office, on the court or in the park with the kids, a smooth and comfortable experience, reducing stress on the back and other joints.

Key Features

  • Powerful and dynamic forward progression
  • Precision machined spring for vertical compression and axial rotation
  • Controlled and efficient energy return
  • Independent e-carbon foot springs
  • Variable spring stiffness heel wedge
  • Slimline design is easy to finish
  • Sandal Toe foot shell

Elite BladeVT Clinical Evidence Reference

Clinical Outcomes using e-carbon feet

  • High mean radius of curvature for Esprit-style e-carbon feet2: “The larger the radius of curvature, the more stable is the foot”
  • Allow variable running speeds3
  • Increased self-selected walking speed4
  • Elite-style e-carbon feet (L code VL5987) or VT units demonstrate the second highest mobility levels, behind only microprocessor feet5
  • Users demonstrate confidence in prosthetic loading during high activity6
  • Improved prosthetic push-off work compared to SACH feet7
  • Increased prosthetic positive work done4
  • High degree of user satisfaction, particularly with high activity users8

Improvements in Clinical Outcomes using shock-absorbing pylon/torque absorber compared to rigid pylon

  • Reduced back pain during twisting movements e.g. golf swings9
  • Reduced compensatory knee flexion at loading response10
  • No reduction in step activity11
  • Blatchford torsion adaptors match the able-bodied rotational range12
  • Reduced loading rate on prosthetic limb13, particularly at fast walking speeds14
  • Users feel less pressure on their residual limb15
  • Patient preference, citing improved comfort, smoothness of gait and easier stairs descent13
