Checking The Socket After Bench Alignment - Ottobock C-Leg compact 3C96-1 Gebrauchsanweisung

Error during alignment of the prosthesis. Errors during the alignment of the prosthesis can lead to
CAUTION
malfunction and insufficient fitting results of the joint up to loss of function due to structural failure. This can cause
the patient to fall. If the residual limb flexion is not taken into account, the joint will be positioned too far to the front.
• Connect the socket and modular knee joint using a corresponding adapter (e.g. 4R111, 4R41 Socket Adapter,
etc.). For alignment correction, use the 4R112 Sliding Adapter (only for temporary use). When using socket adapt-
ers with a 4-hole connection (e.g. 5R1=*, 5R6=*), the 4R118 Sliding Adapter can be used for a permanent, addi-
tional posterior placement of 10 – 25 mm.
Error during alignment of the prosthesis. If incorrectly positioned, the support for the lamination
CAUTION
anchor is not provided. This puts too much strain on the screwed connection adapter and may cause damage and
subsequently cause the patient to fall. The rotation adjustment must not be used for length adjustment. Screw in
the thread as far as possible and clamp with the cap screw. In case of the 4R43 Lamination Anchor with threaded
connector, position the clamp laterally or medially. In case of the 4R111=N Lamination Anchor with threaded
connector, the anchor arms must be positioned in the anterior/posterior and medial/lateral directions.
Here, the clamp must be positioned to show in the anterior/medial or anterior/lateral direction.
• Control of the bench alignment and all measurements.

3.2.1 Checking the Socket after Bench Alignment

CAUTION
Error during alignment of the prosthesis. If the socket drain or air expulsion hole is incorrectly positioned,
the draining sweat may drop into the electric connector and lead to short-circuits in the electronics and malfunc-
tion of the knee joint which may subsequently cause the patient to fall.
Make sure the socket drain or air expulsion hole is not positioned frontally above the electric connector. Position
the hole on the side or back of the socket.
C-Leg compact Prosthetic System
Error during alignment of the prosthesis.
CAUTION
Errors during the alignment of the prosthesis can damage
the hydraulic unit of the joint. A defective hydraulic unit can
lead to malfunction of the joint up to loss of function due to
structural failure. This can cause the patient to fall.
The hydraulic unit may become damaged by contact with
the socket! At maximum flexion and insofar as contact with
3 mm
the frame of the C-Leg compact cannot be avoided (in
1/8"
case of voluminous residual limbs), the socket must lie flat
on the frame. Soft cushioning at the socket will assist in
5 maintaining the socket flat. At maximum flexion, it is essen-
tial that the minimum distance of 3 mm (1 ∕ 8") is maintained
between the hydraulic unit and the socket.
Error during alignment of the prosthesis.
CAUTION
Errors during the alignment of the prosthesis can damage
the electronics of the joint. Defective electronics can lead
to malfunction of the joint. This can cause the patient to fall.
The electronic unit may become damaged by contact with
the socket! At maximum extension (is reached under full
capacity load!) the minimum distance of 5 mm (1 ∕ 5") must
be maintained between the electronic unit and the socket
at the beginning of the dampening phase.
For fittings with the 4X160=* C-Leg Protector, the mini-
6
mum distance between the electronic unit and the socket
must be at least 10 mm (3 ∕ 8").
