Heel height:
Effective heel height (shoe heel height – sole thickness of fore
foot) + 5 mm
Sagittal alignment:
Alignment reference line on a–p markings of the connection
cap/footshell (see fig. 2)
Frontal alignment:
Alignment reference line on m–l markings of the connection
cap/footshell (see fig. 2)
Connect the prosthetic socket and prosthetic foot using the chosen
adapters.
Be sure to follow the adapter instructions for use during adjust
ment and installation.
Sagittal alignment:
Determine the centre of the prosthetic socket with the 50:50
gauge.
Align the prosthetic socket centrally to the alignment reference line.
Socket flexion:
Residual limb flexion of the patient + 5°
Observe the abduction or adduction position.
TF bench alignment
► Observe the information in the prosthetic knee joint instructions for use.
5.1.3 Static Alignment
•
Ottobock recommends fitting the prosthesis using the L.A.S.A.R. Pos
ture.
•
If necessary, the alignment recommendations (TF modular leg pros
theses: 646F219*, TT modular leg prostheses: 646F336*) may be
requested from Ottobock.
5.1.4 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 correct heel
contact and optimal roll-over are ensured.
TT fittings:Make sure that physiological knee movement is achieved
•
after the heel makes impact and the leg begins to bear weight.
•
Remove the adapter cover from the prosthetic foot after completion of
the dynamic trial fitting and gait training exercises.
