System Ankle Joints

with plug + go Modularity

Our product range contains the following modular system ankle joints, that are marked with the plug + go icon: 

  • NEURO CLASSIC
  • NEURO HiSWING
  • NEURO SWING
  • NEURO SWING-CLASSIC
  • NEURO SWING 2
  • NEURO VARIO-CLASSIC 2
  • NEURO VARIO-SPRING 2
  • NEURO VARIO SWING
  • NEURO VARIO 2

Thanks to their modularity, these system joints can be quickly and easily converted from one system joint to another by exchanging a few system components. This online tutorial shows all necessary work steps for the conversion.

You can find the system components for the conversion of the modular system joints in the catalogue pages of the corresponding system joints.

You can also find notes for the assembly and adjustment options of the system ankle joints in the respective instructions for use and in the online tutorials in the joint assembly section.

Step 1/9

All system ankle joints marked with the plug +go icon can be converted to one another by exchanging the functional unit (and spring units, if required) and mounting the spirit level if applicable.

Step 2/9

The same upper parts of the joints as well as the same system stirrups are used for all modular system ankle joints.
These system joints are accordingly labelled with the plug + go icon.

Step 3/9

Other system ankle joints are only modular to some extent and therefore not labelled with the icon.
However, these system joints can be used modularly after the system stirrup has been filed.

Step 4/9

When converting system joints, there is always a
source system joint (here a NEURO VARIO-CLASSIC 2) and a
target system joint (here a NEURO VARIO-SWING).

Step 5/9

Choose the target system joint according to the properties you want to change:

  • spring force
  • range of motion in dorsiflexion
  • range of motion in plantar flexion
  • adjustment options
  • noise reduction
  • adaptation to different pitches

Contact the Technical Support if you have any questions about this.

Note: in modular system joints, static dorsal and plantar stops can only be realised through spring units or adjustment screws. The system stirrup itself is free moving in dorsiflexion and plantar flexion.

Step 6/9

For a conversion, compare the system components of the respective system joints on the pages of our product catalogue.
Open the spare parts tables of:

  • the source system joint (here a NEURO VARIO-CLASSIC 2) and
  • the target system joint (here a NEURO VARIO-SWING).

Identify the respective functional unit and order it.

Important!
If the target system joint contains spring units, you can find these in a separately listed table in the catalogue.
If the target system joint is a NEURO HiSWING, you need a spirit level.

Step 7/9

Disassemble the source system joint:

  • Unscrew both countersunk flat head screws from the cover plate.
  • Place the washer on the cover plate and screw the pressing screw, not entirely, into the thread of the first screw.
  • Push the joint's upper part and the cover plate apart by exerting force on them (see arrows). This can be done by using a vice or by controlled knocks.
  • Remove pressing screw and washer.

Note: a NEURO CLASSIC cover plate can be demounted by just unscrewing the countersunk flat head screws, without causing any damage to the feather keys with pin or their bores.

Step 8/9

Check, as at any maintenance, all system components for wear or any damages and replace them, if necessary.

Step 9/9

Mount the target system joint according to the instructions of the respective joint assembly.
