1. the Trident II acetabular cup menu is comprised of - Trident II (hemispherical)
three implant designs for cementless use only: each Clusterhole HA implant will
cup design will have an outside diameter that will be be .8mm oversized com-
larger than the labeled diameter on the packaging: pared to its labeled diameter
size
- Trident II PSL Clusterhole
HA implant will be 1.8mm
oversized
- Trident II Tritanium Solid-
back, Clusterhole, and Mul-
tihole implants will be .5mm
oversized
2. in total hip surgery, the acetabular socket is pre- - Trident II Clusterhole HA +
pared to accept an acetabular cup implant with an Trident II Tritanium = line to
acetabular reaming instrument. the Trident II ac- line or 1mm UNDER
etabular system of implants is comprised of 3 de- - Trident II PSL Clusterhole =
signs (Trident II Clusterhole HA, Trident II PSL Clus- line to line or 1mm OVER
terhole HA, and Trident II Tritanium) - depending on
the bone quality of the patient, the recommended
reaming guidelines for the three Trident II implants
are:
3. an Offset Reamer Handle is also available for use true
with Trident II
4. when attaching the acetabular implant to the Tri- true
dent II Shell Impactor, the square tip of the impactor
should line up with the square recess on the im-
plant. With light finger pressure the knob on the
instrument should be turned clockwise until the gap
between the knob and the instrument shaft is closed

5. either a lateral decubitus or supine alignment guide true
can be attached to the Trident II Shell Impactor. To at-
tach, the operator should slide the alignment guide
onto the flats of the impactor spindle and rotate it to
the desired location
6. the Trident II lateral decubitus alignment guide has true
a pre-set abduction angle of 45 degrees. The oper-
ating surgeon can adjust the position of the instru-
ment based on the anatomy of the patient
7. the Trident II lateral decubitus alignment guide has true
a pre-set anteversion angle of 20 degrees. The oper-
ating surgeon can adjust the position of the instru-
ment based on the anatomy of the patient
8. the Trident Legacy Cup Positioner/Impactor can be true
used to insert/remove Trident II acetabular compo-
nents. However, the Trident II Shell impactor cannot
be utilized to impact/extract Trident Legacy acetab-
ular implants since these implants do not have the
square recess in the dome of the cup necessary to
thread the implant onto the Trident II Shell Impactor
9. 6.5mm Low Profile Hex Screws can be used with: true
Trident II Clusterhole (hemispherical), Trident II PSL
Custerhole HA, and Trident II Tritanium (Clusterhole
and Multihole) implants. The screw size range is
15mm to 60mm (5mm increments per size). The av-
erage angulation potential of a Trident II Low Profile
Hex screw is 37 degrees.
10. true
, when mounted on a Trident II Ball Joint Drill Shaft,
either 3.3mm or 4.0mm drill bits are used to prepare
the acetabular bone bed to accept Trident II 6.5mm
Low Profile Hex Screws. The 4.0mm diameter drill
bit is utilized in scenarios where sclerotic bone is
encountered
11. centering the drill guide in the cup hole will prevent true
the drill hole from being prepared off center to the
cup hole. if a screw is driven into an off centered drill
hole, the head of the screw might not completely
seat when it is driven into the acetabular cup. if the
head of the screw is not fully seated, the cup insert
will not engage the Innerchange locking mechanism
12. when inserted into either a 3.3mm or 4.0mm Trident true
II Drill guide, the actual screw implant length prepa-
ration will reflect the labeled measurement of the
drill bit (i.e. a drill bit labeled 40mm will prepare a
40mm long pathway for a 40mm 6.5mm Low Profile
Hex Head Screw). In other words, a drill bit labeled
40mm is really 50mm, but 10mm of the drill bit
remains in the head of the angle guide when the
40mm length acetabular drill hole is being prepared
through the wall of the acetabular cup. for drilling
holes deeper than 40mm, it is recommended to drill
sequentially with a 25/40mm bit and follow with a
60mm bit to deepen the hole to the desired depth
13. operating the Ball Joint Drill Shaft at angles exceed- true
ing 45 degrees for prolonged periods of time or with
, excessive force can lead to damage to the flexible
joint and drill bit
14. Screw Depth Gauges are available to measure the true
prepared drill hole depth in the acetabulum. the sur-
geon can use the hook located at the tip of the instru-
ment to locate the end of the bone hole prepared by
the drill bit. the visible end of the gauge shaft can be
clamped on the near side of the hole in the implant
and then removed for measuring. the gauge shaft
has marking to aid in selecting the appropriate screw
length.
15. a Ratchet Driver Handle can be used with Captive true
U-Joint Driver, a Straight Driver, or a Non-Captive
U-Joint Driver. a Screw Forceps is also available to
hold the screw in position as the selected driver in-
serts in
16. Trial Acetabular Liners are available with an optional true
feature that fastens the trial liner to the acetabu-
lar implant. Trident II Acetabular Liner implants are
available to accommodate 22mm, 28mm, 32mm,
36mm, 40mm, and 44mm diameter femoral head
implants
17. Trident II Acetabular Cups are compatible with Tri- true
dent X3 and Crossfire Polyethylene Liners, Trident
Constrained Liners, and MDM Liners and Poly Inserts
18. Trident II Acetabular Liner Chart for Standard 0 de- true
grees, 10 degrees, and Elevated Rim Liners is coded
to reflect liner design availability when matched with
