Use 2Z11=KIT
INFORMATION: The connection area of the prosthetic knee joint can be protected against
scratches with the protective film of the 2Z11=KIT during alignment in the workshop and testing
in the trial fitting area.
f Use the protective film as illustrated in the accompanying document for the 2Z11=KIT.
f Remove the protective film before the patient leaves the fitting area.
4.1 Alignment
The three-dimensional arrangement of the prosthetic socket and the modular components affects
the static and dynamic functions of the prosthesis. Function of the joint is influenced by the posi-
tion of the axes. In extension, the instantaneous centre of rotation is located above the adjust-
ment pyramid and behind the alignment reference line, thus providing knee stability in the stance
phase (Fig. 4). The advantages of the EBS Knee Joint can only be made optimal use of in case
of a correct alignment.
The optimal residual limb position must be anticipated when positioning the socket connec-
tor. Plumb lines in the frontal and sagittal planes (drawn from the hip joint's centre of rotation and
marked during plaster cast taking and trial fitting of the test socket) will facilitate correct position-
ing of the lamination anchor or socket adapter.
To align the prosthesis please proceed in two steps:
1. First make the bench alignment using an alignment tool such as 743L200 L.A.S.A.R. Assembly;
PROS.A. Assembly 743A200.
2. Then use 743L100 L.A.S.A.R. Posture for static alignment optimization.
4.1.1 Bench Alignment with Alignment Tool (the following steps refer to Fig. 12)
Position the middle of the foot 30 mm anterior to the alignment reference line.
1
Add 5 mm to the required heel height of the foot. Set correct outward rotation of the foot.
