It is important to check that the studs do not
stand proud of the inner surface of the shell.
Impacting the studs
The studs must be re-impacted after screwing the cortical screws.

5 Impaction of the insert over the head
Head alone (on the table)
Option
Impaction in situ (head on stem)
Important: In both cases remove any liquid from inside the insert
at the moment of impaction, as this may render the snap fit over
the head impossible.
Before reduction ensure that the head moves freely within the in-
sert. Residual air may prevent this from happening, in which case
re-compress to chase out any trapped air.
SERF cannot take responsibility for use of inappropriate implant
association.
