Optimising The Alignment Of Prostheses And Orthoses - Otto Bock 743L500 3D L.A.S.A.R. Posture Instructions For Use Manual

5.7 Optimising the alignment of prostheses and orthoses

INFORMATION
The information in this document provides a brief overview of the possibilities offered by the 3D L.A.S.A.R. Pos­
ture for optimising the static alignment of prostheses and orthoses. Ottobock training for the 3D L.A.S.A.R. Pos­
ture imparts theoretical and practical knowledge for using it successfully.
Optimum static alignment makes it possible for the patient to stand in a relaxed posture and establishes the basis
for optimisation during the dynamic trial fitting.

Optimising the alignment of prostheses and orthoses is
performed in the following sequence:
1. Optimisation
Page 113) – 3D symbol: green
2. Optimisation with 3D mode deactivated (see
Page 116) – 3D symbol: dark grey
It is important that the patient stands on the force meas­
urement plate with a relaxed body posture as far as
possible (section "Positioning the patient" - see
Page 89). If this is the case, it can be assumed that
deviations from the characteristics for optimum, relaxed
standing are caused by sub-optimal static alignment
and can be changed through corresponding correc­
tions.
The following characteristics indicate optimum, relaxed
standing:
• Sagittal load line
3D mode activated and deactivated: parallel to each
other, overlapping, bottom end of the load line (load
transmission point or force transmission point) in

• Frontal load lines
3D mode activated: runs through knee centre
3D mode deactivated: runs along the lateral patella
edge
• Load ratio between the plates
~ 50:50 (load ratio for prosthetics: section "Posi­
tioning the patient" - see Page 89
The symbol and value are shown in red if the value
is less than 40%.
