Important Information On The Completion Of A Helix; Test Prosthesis - Ottobock 7E10 Helix 3D Instrucciones De Uso

3.2.1 Important information on the completion of a Helix

Maximal abduction / adduction
1. Use only the bore holes in the lamination plate marked in Figure 1 below to screw the lamination plate (7Z53)
to the pelvic socket in the frontal plane.
This will allow maximal abduction / adduction adjustment of the hip joint, if necessary (Fig. 2).
2. On the bottom side of the lamination plate, all bore holes can be used for the screw connection to the pelvic
socket.
Maximal internal / external rotation – use of the 4G576 Spacer Washer
INFORMATION
As described in Section 3.2 (positioning of the lamination plate) of the Helix
that you insert the plaster wedges rotated outwards 5° when plastering the pelvic socket.
For the test fitting period, use the spacer provided as shown in the figures below.
In this way, maximal internal and external rotation of the hip joint can be set / used, without the posterior linkage
bar contacting the lamination plate.
INFORMATION
The 4G576 Spacer Washer is intended solely for use during the trial fitting period. When fabricating the defini­
tive pelvic socket, make sure that the lamination plate is attached with sufficient external rotation and that the
pelvic socket has a laminate thickness of at least 2.5 mm.
If the posterior linkage bar of the hip joint contacts the pelvic socket in spite of this, you can grind the laminate
at this point.
