Prior to final head assembly, neck length/head offset
may be re-evaluated using a V40 Head Trial. Place the
Head Trial on to the stem neck taper and reduce the hip.
Leg length equality and proper soft tissue tension are
evaluated. Remove the Head Trial and dry the implant
trunnion with a laparotomy sponge or sterile towel.
Select the appropriate corresponding V40 Femoral Head
(CoCr, Alumina Ceramic, BIOLOX
delta Ceramic) or
sleeve and place it onto the dry trunnion of the femoral
stem with a slight twist. Impact the head with moderate
impactions using the Modular Head impactor.
Verify the head is secure on the trunnion after head
impaction by applying traction to the head and confirming
stability on the trunnion.
When selecting a BIOLOX
delta
Universal Taper Ceramic
Femoral Head for implantation with the Secur-Fit
Advanced Stem, use of a V40 Universal Adaptor Sleeve
is necessary. After completing the trialing process, intra-
operatively assemble the Adaptor Sleeve to the Femoral
Stem manually. The Universal Adaptor Sleeve must be
fully seated on the Stem trunnion before the Head is
assembled.
Relocate the femoral head into the acetabular cup and
re-check the laxity and range of motion. The surgical site
is then closed according to surgeon preference.

Note
in no instance should any attempt
be made to preassemble the
Adaptor Sleeve inside the BiOLOX
delta universal ceramic Head. intra-
operatively assemble the BiOLOX
delta universal taper ceramic Head
onto the sleeved Femoral Stem
and set with moderate blows using
the Stem Head impactor (1104-
1000). care must be taken to avoid
excessive impact forces when
assembling the ceramic Head to the
sleeved femoral component.
