3.7 Dynamic trial fitting

INFORMATION
Using the check prosthesis
The user should only use the check prosthesis under the supervision of an orthopaedic technician.
On the basis of his or her professional experience, the orthopaedic technician can decide whether the user can
take the check prosthesis home for an extended trial fitting.

3.7.1 Preparation

3.7.2 Testing the vacuum system

Required tools and materials
• 755Z37 manometer, air-tight adhesive tape,

3.7.3 Trial fitting

Donning the prosthesis
1) Don the liner onto the residual limb.
2) For liners without textile cover: Pull a residual limb sock on.
3) Put on the prosthesis.
4) Pull the residual limb sock or the protruding textile material over the socket brim.
5) Pull the sealing sleeve over.
Dynamic trial fitting
► Perform the trial fitting, verifying the following:
• Seal between socket adapter and prosthetic socket.
• Screw lock and tightening torques.
• Prosthesis fitting with the L.A.S.A.R. Posture, if possible.
Instructing the user
► Instruct the user on the use of the prosthesis. The following are especially important:
• Check the fit of the prosthetic socket every morning on the basis of the mediolateral lines on the liner.
• Feel the vacuum.
• Use the 451F20 liner FitKit.

3.8 Fabricating the definitive socket

Objective
The following section describes the fabrication of the definitive prosthetic socket. The fitting of the check prosthes­
is is transferred for the definitive prosthesis. A sleeve protector can be laminated if necessary.
Harmony System
Secure the connection between the check socket and
components of the modular system with a stiff bandage
(e.g. Cellacast Xtra 699G30).
Connect the manometer to a T-piece.
Seal the hole on the inside of the prosthetic socket with
a piece of paper and air-tight adhesive tape.
Generate vacuum and verify that it is maintained.
If the vacuum is not maintained, check the system with
the help of the troubleshooting table (see Page 24).
