Registrations

Place tip of probe into hole of the pelvic base and press center button. 

 
 
 

 

 

 
 
 
 
 
 

WARNING:

 

Register Table

 

 

Position operating table horizontally. 

 

Verify the sagittal plane of pelvis is level. 

 

Move probe, with reference sensor attached, to align parallel long axis of body 
with the tip pointing towards the feet. 

 

Press the center button to register. 

 

Correct patient positioning is essential for accurate navigation. The system calculates cup angles based on the assumption 
that the pelvis is accurately positioned during table registration.

 

 

Table registration must be completed prior to dislocating hip, as torque applied during dislocation can move pelvis away 
from the correct initial alignment.

 

 

Pelvic Base cannot be moved after this point.

 

 

Pelvic Bracket angle to the base cannot be adjusted after this point.

 

 

If fixation pins become loose, navigation must be aborted, since table registration is no longer valid.

 

 
 
 

Registering Femur

 

 

Make the standard incision and identify a point along greater 
trochanter to insert a registration marker for femoral 
registration. Insert femur registration marker. 

 

Open laser shutter, place the vertical target on the thigh plate and 
align the leg so that the laser projects onto  the lower part of the 
target. 

 

Trace the crosshair pattern with a marking pen. 

 

While laser projection is aligned with laser marking, hold the 
probe tip in the center hole of the marker and press the  center 
button to register the femur.  

 

Close shutter on the laser and remove vertical laser target. 

TIPS

:

 

1.

 

When marking the vertical target and registering the femur 
registration marker, position  the thigh in neutral flexion, 
abduction and rotation.

 

2.

 

Stack legs vertically atop each other in a stable position which 
will be easy to return to prior to registration.

 

 

WARNING:

 

 

If laser module moves, leg length must be aborted since leg alignment cannot be replicated.

 

 

Discontinue use if unable to verify thigh plate is aligned with original marking on skin or if unable to return it to 
original position.

 

Prepare Acetabulum

 

NOTE

: Once registration is complete, proceed to dislocate the hip, resect the femoral head, and prepare the

 

acetabulum as per the implant manufacturer’s technique.
