Remove soft, flexible or porous materials from beneath the support surface of the lamina-
tion anchor. Mix the putty exclusively from 617H21 Orthocryl Sealing Resin and 639A1
Talcum Powder, and glue on the lamination anchor.
Secure with 627B2 Adhesive Tape for trial fitting. Test the stop function (see Section 4.1). If neces-
sary, form the required contact surface with putty. It is also possible to glue a stop bumper of Pedilin
onto the outer laminate.
4.3.1.3 Socket completion
Once the trial fitting has been completed, attach the lamination anchor to the socket with truss head
screws and joint nuts, and then laminate.
Proceed with further reinforcement as follows:
1. Two layers of 616G12 Carbon Fiber Cloth must be sandwiched between two layers of 623T3
Perlon Stockinette. To do this, pull one layer of 623T3 Perlon Stockinette over the whole socket
and tie it on the top circularly, apply the two layers of 616G12 Carbon Fiber Cloth over the arms
of the 4G70 Adapter, and then reflect the remaining half of the 623T3 Perlon Stockinette over the
carbon fiber layers.
2. Now the socket is to be reinforced once again with 616G13 Fiberglass Stockinette (as described
in Section 4.3.1.1).
3. Finally, pull on 2 layers of 623T3 Perlon Stockinette. Proceed with lamination as performed in the
first stage of lamination.
Attention!
Deviating from the processing instructions and the recommended materials for the lami-
nation of the anchor can lead to a loosening or breaking of the adapter.
Upon completion of the assembly tighten the adjustment screws with 710D1 Torque
Wrench. Torque: 15 Nm/11 lbf.ft/133 lbf.in. Once you have attained the final setting for
the prosthesis, use 636K13 Loctite to secure the set screws.
4.3.2 Adjusting the knee joint during trial walking
The user will notice that the EBS
PRO
Knee Joint is different from other prosthetic knees because of
the Ergonomically Balanced Stride function. With EBS
PRO
, the user can walk with a natural gait,
allowing the knee to flex during stance phase without risk of falling (Fig. 3a). Trial walking should be
started with the bench alignment and the factory-set base setting. During trial walking, explain the
important, biomechanically advantageous EBS
PRO
function to the patient.
For optimal function, in addition to proper alignment and adjustments, the patient
must be taught to use the stance flexion feature. The comfort and stability provided
by the knee are most noticeable when walking long distances or on uneven surfaces.
Initially, the patient may be unaccustomed to the cushioned knee flexion at heel strike.
With proper instruction and experience, the amputee will learn to take considerable
advantage of this more natural gait pattern. Therefore, allow the prosthesis wearer to
get accustomed to the joint.
Before changing the factory settings, the following guidelines must be observed:
• For changing the degree of stance flexion, first correct the position (see Section 4.3.2.1), then
re-adjust the EBS
PRO
unit (see Section 4.3.2.2).
