17CF1 Carbon Ankle Seven

Carbon Ankle Seven
Reference number 17CF1
Function Dynamic components
Dynamics without compromises

The Carbon Ankle Seven ankle-foot orthosis supports the user in walking naturally to a large extent and conserving his or her own strength. The carbon spring adapts to the individual requirements of the wearer.

All benefits at a glance:

  • The carbon material is lightweight and stable. Its energy returning characteristics allow for a particularly dynamic gait pattern.
  • The physiological 7° outward rotation of the carbon spring allows for precise alignment of the lower limb.
  • The jointless construction requires no predefined dorsal or plantar stops.
  • Thanks to the special design, energy is stored in the carbon spring at heel strike and released again at toe-off.
  • The orthosis can be selected individually for the patient according to activity and weight parameters.
  • It is suitable for active users with a body weight of 10 to 100 kg.

Indications Loss or weakness/restriction, of the foot lifting and foot lowering muscles while using a dynamic ankle-foot orthosis (DAFO), of the knee extensors while using a knee-ankle-foot orthosis (KAFO) with a locked knee joint.
Diseases such as spina bifida or poliomyelitis are commonly indicated.
How it works The carbon springs are designed to initiate extension moments of the hip and knee during walking, and thus achieve extension and knee stability in the lower limbs. The energy generated during heel strike is stored in the carbon matrix and returned at toe-off. In contrast to conventional ankle joint orthoses, the limits in the plantar and dorsal direction are dynamic and without static restriction.
Features & benefits Positive influence on the gait pattern, extremely lightweight design, 7° outward rotation supports the physiological alignment of the foot, classification makes product selection easy, appropriate for thermoplastic and lamination resin orthoses
Sizing chart

You can easily find the right article number in the provided classification matrix. Simply select the affected side (e.g. 17CF1=L9 for the left side with a normally active patient who weighs up to 30 kg). The delivery includes detailed mounting instructions as well as the attachment material needed for the integration into an orthosis. The classification applies to AFOs that are intended to influence the knee joint. The use of the Carbon Ankle Seven carbon spring for KAFOs may require a deviation from the classification. The specified weights are important for functionality, not durability.
