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)
Perform the assembly and alignment of the prosthetic components in the alignment
apparatus according to the following specifications:
Sagittal plane
Heel height: Effective heel height (shoe heel height - sole thickness of fore­
foot) + 5 mm
Exterior foot rotation: approx. 5°
Anterior placement, middle of the prosthetic foot to the alignment reference
line: 30 mm
Connect the prosthetic foot and prosthetic socket using the chosen adapters.
The instructions for use of the adapters must be observed.
Determine the centre of the prosthetic socket with the 50:50 gauge. Align the
prosthetic socket centrally to the alignment reference line.
Socket flexion: Individual residual limb flexion + 5°
Frontal plane
Alignment reference line of prosthetic foot: between big toe and second
toe
Alignment reference line of prosthetic socket: along the lateral patella
edge
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 checking the alignment of the prosthesis using
the L.A.S.A.R. Posture and adapting it as needed.
