Make sure that the patient’s stump is
now loaded statically and completely,
or at least as well as possible. For-safe-
ty reasons, please provide
something
that the patient can hold onto.
Due to
the corresponding water pressure, the
stump is put under completely uniform
weight. A particular advantage of this is
that the resulting displacement of soft
tissues, which is normal when subjec-
ted to weight, already occurs during the
plaster casting.
Depending on the type of the plaster
bandages that are used, wait for the
usual hardening time with the stump
subjected to
full weight and static
. The
patient can already provide you with va-
luable information about the shaft volu-
me and the bony structure of the stump
during the hardening time. The com-
pression on the stump that is achieved
by the body weight and the water pres-
sure facilitates making the plaster mo-
del (check the circumference measure-
ments!). After the plaster bandages
have hardened, the patient reduces
the load on the amputated leg. Open
the stopcock again and allow the water
to escape. The patient can now remove
the plaster-covered stump. Remove the
plaster cast by slowly pulling it off the
stump. Begin making a trial shaft.

Please note the danger of slipping due
to leaking water.
Use only the Symphonie Aqua membra-
ne made by Romedis GmbH!
1. Before replacing the membrane, all
the water in the Symphonie Aqua sys-
tem needs to be drained. Make sure
that the water in the cylinder can flow
into a receptacle provided for this pur-
pose. Since the water is free of addi-
tives, it can be disposed of normally
via the sewage system. To do this,
place the cylinder above a receptac-
le, disconnect the cylinder hose and
the compensation reservoir and open
the stopcock as well as the ventilation
screw (Figs. 23, 24).

Please make sure that the stump sinks
completely into the cylinder, up to the
level of the proximal shaft edge. Once
the desired depth has been attained
(depending on the proximal shaft edge),
close the stopcock (Fig. 22).
After you have applied the plaster ban-
dages, pull a thin nylon stocking over
the wet plaster (Fig. 18).
Make sure that the patient can stand
on the amputated leg for the duration
of the casting.
The patient can now stand up to insert
their stump into the opening of the cy-
linder. If soft tissues are overhanging,
we recommend that the stump be in-
serted into the empty cylinder and st-
arting to refill the water after this. This
prevents an excessive displacement of
the soft tissues in the proximal direc-
tion (Fig. 19). In order to allow the pati-
ent to uniformly lower the leg (Fig. 20)
into the cylinder, now open (Fig. 21) the
stopcock to permit the corresponding
volume of water to escape. This water
flows into the compensation reservoir.
