3.1.3 Lamination technique
By pouring 617H17 Orthocryl Flexible Resin into the ventrally and dorsally inserted filling hoses,
these sections can be formed as desired. Pour 617H19 Orthocryl Lamination Resin into the
affected side.
It is important that the lamination and evacuation steps are performed separately and, if possi-
ble, by 2 prosthetists, to ensure that the resin remains in the desired position during the process
3.1.4 Completion and setting-up
• Once the resin has hardened, cut open the pelvic socket at its brim.
• Use a knife to cut open the outside and inside flaps along the Trolene brim.
• Remove the pelvic socket from the plaster positive and grind the brim smooth.
• Expose the threaded hole of the lamination plate and mount the hip joint to the pelvic socket.
3.1.5 Using the 7Z58=N lamination dummy
After having completed the trial fitting of the pelvic socket with the mounted hip joint, the hip joint
must be disassembled again and a protective or connection cap be fabricated using the enclosed
lamination dummy in order to ensure the function of the hip joint and for the later connection to a
cosmetic foam cover. To position the lamination dummy/ protective cap properly, the protruding
guide pins of the lamination dummy must be inserted into the two threaded holes provided in the
lamination plate.
3.2 Alignment
Figure 2 shows the alignment recommendation for a pelvis prosthesis with 7E7 Hip Joint, 4R56
Angled Tube Clamp Adapter, 3R60 Knee Joint and 1C30 Trias.
The Angled Tube Clamp Adapters are designed especially for adjustable connection between the
tube of the hip joint and pyramid adapter of the knee joint. The Angled Tube Clamp Adapter has
a 10° angle (4R56), a 20° angle (4R56=1) or a 30° angle (4R56=2) depending on the position of
the tube of the anteriorly located hip joint.
3.3 Adjustment options
The 7E7 Hip Joint is adjustable in three planes: abduction-adduction, flexion-extension and hip
axis rotation (Fig. 3).
3.3.1 Abduction - adduction to the pelvic socket
Using a 710D4 Torque Wrench and 709Z11 Bit T40 (29), loosen the two 501F9=M8x25 Pan
Head Screws (22) (Fig. 4) until the hip joint can move with respect to the pelvic socket. Set the
required position ± 10° (Fig. 5.1).
3.3.2 Rotation position of the hip axis
The rotation adjustment can be set between the Upper Joint Section (2) and Bottom Plate (21).
To do this, loosen the two pan head screws with the 710D4 Torque Wrench and 709Z11 Bit T40
(29) (Fig. 4) and additionally loosen the Cap Screw (27) with a 3-mm Allen wrench (Fig. 6). Set-
ting range ± 5° (Fig. 5.2, 5.3).
