adapter with pyramid receiver is used, note that a collision between the received pyramid of the
connecting component and the connection adapter has to be prevented. One or more 4Y19 pres­
sure plates may have to be installed.
The longest possible screws must be used for each screw connection. If the longest screws col­
lide with the medial side rail, the shorter screws have to be used.
Optional: re-shaping the socket shells
28
The socket shells can be re-shaped with a hot air gun if needed.
The following areas can be re-shaped:
• Lateral socket shell in the area between the Boa dials (to bring the lateral socket brim into
contact with the body) (see fig. 28)
• Anterior section of the socket brim (increase the outward flare) (see fig. 29)
• Medial and lateral socket shell with distal area directly next to the side rail guides (reduce
socket cross-section in the distal area)
• Area of the socket brim pad (to optimise pressure distribution in this area)
INFORMATION
When heating the socket shells with the hot air gun, make sure to heat them evenly (from the
inside and outside of the socket). Excessive heating causes glossy areas on the matt surface of
the socket shells.
7.5 Verification of function and fit
Inspecting the liner edge
The liner edge should be 1-2 cm higher than the socket brim.
If pressure on the medial socket brim is excessive when checking the fit, the socket can be
shortened. This shifts the pressure to the distal area of the socket.
If the pressure on the residual limb end is too high when checking the fit, the socket can be exten­
ded.
