Product Change: Alignment Screw with Hexagon Socket Drive, Raised Countersunk Head and Rotation Mark

Dear Readers,

In today’s issue, we will once again discuss the optimised alignment screw for our system ankle joints with spring units, including another product change: a rotation mark on the raised countersunk head of the screw.

With best regards from Lüneburg, Your FIOR & GENTZ team

Product Change: Alignment Screw with Hexagon Socket Drive, Raised Countersunk Head and Rotation Mark

We have now converted the following system ankle joints in the system width 12mm to the new alignment screw:

• NEURO SWING

• NEURO VARIO-SWING

• NEURO CLASSIC-SWING

• NEURO SWING-CLASSIC

This means that the system widths 12, 14, 16 and 20mm have already been converted. Soon, the 10mm system width will follow. The new system ankle joint NEURO SWING 2 was equipped from the start with the optimised alignment screw in all system widths.

Hexagon Socket Drive for Easy Assembly

We have equipped the alignment screw with a hexagon socket drive. This allows an easy handling during assembly. The hexagon screwdriver with spherical head can be held at an oblique angle when screwing in the alignment screw, which considerably simplifies assembling and adjusting the orthosis.

The slotted screwdriver that was used for the previous version of the alignment screw could only be held vertically. This was a problem because during the rotation movement, pressure had to be applied to the screwdriver from above all while the orthosis shell was in the way.

Furthermore, the alignment screw now has a raised countersunk head. This prevents sharp edges of the thread of the screw protruding from the spring duct during extreme changes of the orthosis’ alignment.

Rotation Mark for Precise Adjustment of the Orthosis

With the hexagon socket drive of the alignment screw, it can be difficult to see how many rotations are made when adjusting the spring unit. This can be important, for example, with the NEURO SWING system ankle joint in order to know how many rotations you have to make in the opposite direction with the second alignment screw.

For this reason, the optimised alignment screw has undergone a second product change: a rotation mark on the raised countersunk head in the form of a dot, which can be used for orientation when screwing in the alignment screw.

Adjusting the Orthosis on the Workbench

After having adjusted the orthosis, it is extremely important to check the orthosis for play. We therefore highly recommend adjusting the orthosis with the appropriate shoe exclusively on the workbench. This is the only way to check whether the orthosis can be moved without play.

If you adjust the orthosis on the patient’s leg, it can be difficult to see whether you are screwing in the alignment screw too far, thus pre-compressing the spring unit and restricting the range of motion.
