System Ankle Joints for Orthoses
System ankle joints can contain multiple functional elements. Functional elements have a decisive effect on the orthosis function. Depending on the intended orthosis function, different functional elements can be combined with one another.
With the Orthosis Configurator, you can easily and quickly determine the best option for the patient's system ankle joint. Based on the patient data, the Orthosis Configurator identifies the best combination of functional elements and thus guarantees an individually fitted orthosis’ alignment that ideally compensates for the patient's functional restrictions.
The orthosis functions dorsiflexion stop and plantar flexion stop have a decisive role in the orthosis' overall effect. With regard to the dorsiflexion stop, an orthosis can be equipped as follows:
- no dorsiflexion stop
- with static dorsiflexion stop
- with dynamic dorsiflexion stop
Below you will find an overview of the FIOR & GENTZ system ankle joints divided according to the type of dorsiflexion stop:
System Ankle Joints with No Dorsiflexion Stop
System Ankle Joints with Static Dorsiflexion Stop
System Ankle Joints with Dynamic Dorsiflexion Stop
The following variants are available for the plantar flexion stop:
- without plantar flexion stop
- without plantar flexion stop, with dorsiflexion assist
- static plantar flexion stop
- dynamic plantar flexion stop, with dorsiflexion assist
FIOR & GENTZ system ankle joints offer adjustment possibilities in the range of motion in
- dorsiflexion
- plantar flexion
- dorsiflexion and plantar flexion
plug + go Modularity due to Exchangeable Functional Units
The functional elements are integrated into the cover plates of the system joints. The functional elements by FIOR & GENTZ include, for example, precompressed spring units in various spring forces as well as system components for adjusting the ideal orthosis’ alignment. The orthosis’ alignment, the range of motion and the orthosis' rigidity can be adjusted independently as required for all important orthosis functions, such as dorsiflexion stop and plantar flexion stop.
In combination with the functional elements, the cover plates constitute the functional units of the system joints. Many FIOR & GENTZ system ankle joints can be converted from one to another. System ankle joints with plug + go modularity (identified by the plug + go logo) are especially easy to convert, as they have identical system stirrups, joint’s upper parts and assembly/lamination dummies. All functional differences are integrated in the functional unit. A joint-specific functional unit therefore is all that is needed for the conversion. Thus, by using system joints with plug + go modularity, the orthosis can be adjusted flexibly to the course of therapy and expensive new productions can be avoided.
