This articulating system is meant to compensate weakened or Total Failure of the Knee Extension

function .

The SPL 2 Joint offers knee stability during stance and offers free movement of the knee during swing .
This feature is fully automatically activated with each step . It is prohibited to be used in water or
exposed to temperatures exceeding 50°C .
Important
The patient must be well informed concerning the functions and possibilities of the Knee Joint system .
Function

Technical Features SPL 2

The technique of the SPL 2 Joint (Swing Phase Lock) is based on a simple internal pendulum
mechanism, which locks and unlocks the knee depending on the angle of the Joint in the sagittal
plane . During gait, the device locks at the end of swing phase, just prior to heel strike, and unlocks the
knee at heel off in preparation for swing. The Joint cannot be unlocked if it is loaded in flexion.
The SPL 2 Joint is always to be mounted on the lateral side and is suitable for 19 mm Uprights.
The Joint weight is 340 grams .

Technical Features SPC

De technique of the SPC Joint (Swing Phase Control) usage friction to regulate or influence excessive
Knee Flexion. The moment to full flexion is somewhat shortened and slightly variable.
The SPC- Joint is always to be mounted on the medial side and is suitable for 19 mm Uprights. The
Joint weight is 190 grams .

Technical Features Satellite

The SPL 2 Joint is controlled by a proximal remote push-button switch (Satellite) . The Satellite is
mounted to the thigh part of the orthosis with the mounting bracket that is supplied in the packaging .
30 Swing Phase Lock 2
The 3 modes to manually control the SPL 2 Joint are:
1 . Automatic locking
2 . Permanent unlocking
3 . Permanent locking
By deactivating the permanent unlocking mode the Satellite switches into the permanent locking
mode and needs to pushed into the Automatic function .

Cleaning / disinfection Instructions

The SPL 2 Joint may not be greased, oiled or in any other way lubricated . When cleaned, please use
Naphtha (no acetone, dilutions or turpentine, etc.) or some similar cleaning fluids or compressed air.

Maintenance Instructions

Maintenance cycles depend strongly on the patients activity level . At a moderate activity level,
the Joints must be checked / serviced every 6 months . When doing this, attention must be paid to
wear and tear, Joint play and damages . If the Joint is no longer running freely, a thorough service is
recommended .
If the Joint has been, due to circumstances, extremely heavily loaded in a flexed position e.g. with
stumbling, tripping or walking (falling) down the staircase, the Joint has to be inspected by the
Orthotist. In case the patient constantly walks with a slightly flexed knee or regularly usage the safety
stops, adjustment of the extension position towards flexion is absolutely necessary.

Constructional guidelines

Orthosis construction

Measuring

Casting must be done with a fully, in neutral, extended leg . Stretching however should be possible
without to much effort to allow full extension (needed to unlock the Joint) once the Orthosis is worn .
When the Alignment Unit is used (Art. nr. IQ150) to construct the Orthosis, make sure the square with
the T-bar is placed horizontal in the Frontal Plane to keep the axis straight . Alignment should be based
on the plumb line to create a neutral baseline for the Function Unit .
