Static Alignment; Dynamic Trial Fitting; Aligning The Prosthetic Foot - Ottobock 1E91 Runner Instrucciones De Uso

a–p position of the reference point to the alignment reference
line: -15 mm
Frontal alignment prosthetic knee joint
Lateral rotation: approx. 5°
Connect the prosthetic foot and prosthetic socket using the chosen
adapters. Be sure to follow the adapter instructions.
Sagittal alignment prosthetic socket
In proximal area centred on alignment reference line
Socket flexion
Residual limb flexion of the patient + 5°
Observe the abduction or adduction position.

5.4.2 Static Alignment

• Ottobock recommends fitting the prosthesis using the L.A.S.A.R. Pos­
ture.
TT prostheses: The load line should run approx. 15 mm anterior to the
•
compromise pivot point according to Nietert.
TF prostheses: The load line should run approx. 40 mm anterior to the
•
rotation axis of the prosthetic knee joint.

5.4.3 Dynamic Trial Fitting

• Adapt the setup of the prosthesis in the frontal plane and the sagittal
plane (e.g. by making angle or slide adjustments) so that optimal rollover
is ensured.
TT fittings:Make sure that physiological knee movement is achieved
•
after the leg begins to bear weight.
• Adapting the alignment of the prosthetic foot (see Page 20). The align­
ment of the prosthetic foot is optimised if it points straight forward when
it is set down.

5.5 Aligning the prosthetic foot

Moving
The prosthetic foot can be shifted in the connection adapter. It is shifted on
a radius which changes the angle of the heel strike and the dynamics of the
prosthetic foot. The bench alignment remains unchanged, as moving does
not have an effect in the a–p direction.
