5.1.2 Bench Alignment
TT bench alignment
Required materials: 662M4 goniometer, 743S12 heel height measuring
apparatus, 743A80 50:50 gauge, alignment apparatus (e.g. 743L200
L.A.S.A.R. assembly or 743A200 PROS.A. Assembly)
Assemble and align the prosthetic components in the alignment apparatus
according to the following specifications:
Heel height: Effective heel height (shoe heel height - sole thick
ness of forefoot) + 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 foot and prosthetic socket using the chosen
adapters. Be sure to follow the adapter instructions for use.
Sagittal alignment:
Determine the centre of the prosthetic socket with the 50:50
gauge. Align the prosthetic socket centrally to the alignment refer
ence line.
Socket flexion: Residual limb flexion of the patient + 5°
Observe the abduction or adduction position.

Ottobock recommends checking the alignment of the prosthesis using
the L.A.S.A.R. Posture and adapting it as needed.
•
If necessary, the alignment recommendations (TF modular leg pros
theses: 646F219*, TT modular leg prostheses: 646F336*) may be
requested from Ottobock.
