NOTE: Holding Left and Up buttons
simultaneously powers unit off
 Risk of communication errors increases if multiple OrthAlign Plus® systems are used in close proximity.
 If navigation unit is dropped on floor, it must be discarded. If reference sensor is dropped on floor, it must be returned
to manufacturer for verification of function and calibration.
 Probe scale and lens of reference sensor must be kept clean for reliable operation. Note that lens of reference sensor is
on its underside.
 Avoid impacting jig and electronics. Verify position of jig and electronics after impacting and before checking angles.
LASERMODULE/OTHER INSTRUMENTS:
 Inspect laser module prior to use. Do not use laser module if it appears damaged or moisture is
present under the lens.
 If laser module fails to function after initial registration, abandon leg length and offset measurement
feature.
 The laser module is a Class 2 laser product, maximum output: <1mW, emitted wavelength: 635nm,
duration > 0.25 seconds (continuous), beam divergence: 10 degrees, per IEC 60825-1: 2014-
05. This information can be found etched onto the back surface of the laser module.
 Do not stare into beam. Eye damage could result.
 Take care when using laser to avoid possible dazzle, flash-blindedness or after-image effects.
 Use of controls of adjustments or performance of procedures other than those specified herein may result in hazardous
radiationexposure.
 Use the movable shutter on the front of the laser module to expose the lens for use, and cover the lens to stop projection
of the laser beam.
 Once the battery is installed, the laser is always on and the shutter must be closed to stop projection of the laser beam.
 The strong magnetic fields near a neodymium magnet can affect pacemakers, ICDs and other implanted medical devices.
Keep the laser module, vertical laser target, adapter socket driver and any other instruments with magnets at least six inches
away from any such heart device.
SURGICALTECHNIQUE:
 Utilize standard surgical practice in joint reduction (for joint stabilityand soft tissue laxity).
 Take care to avoid damage to nervous and vascular structures when using registration probe to register landmarks or
when mounting jig.
 Do not impact or hammer system components except where components are designated as impactor devices.
Acetabular shell impactor may be impacted.
 Abort the use of the navigation feature if the landmarks cannot be identified or registered.
 Remove all pins, screws, and other instruments prior to closing wound. Do not implant any system components.

Securing Base
Securing Pelvic Base
Placement of the fixation pins in the iliac crest should be vertical to optimize orientation of
theinstrumentation.
For the first pin, make a stab incision
over the ipsilateral iliac crest, directly
superior to the greater trochanter.
Insert a 4.0mm threaded fixation pin
vertically using a wire driver.
Make a second stab incision, and insert
the second fixation pin in the iliac crest
2cm anterior parallel to the first
pin. You may use the pelvic base as a
guide for spacing between the pins.
Slide the Pelvic Base over both pins to
the level of the skin, and use the 3.5mm
Hex Driver to tighten the two bottom
screws to secure Base.
WARNING:
 The base must be attached prior to dislocating the hip to ensure correct patient positioning and navigation accuracy.
 Take care to avoid plunging through the medial wall of the iliac wing.
 Verify that pelvic base is securely mounted to the bone.
 Take care to minimize divergence of pins, as excessive bending can damage pins.
 Ensure pins are aligned in the tracks within the pelvic base and the base is clamped on the cylindrical part of the pins.

Aligning Jig
 Place the leg on the operative side in a neutral
abduction, flexion and rotation using a roll if necessary.
 Place the thigh plate on the lateral distal thigh and secure using
Coban™ by wrapping around thigh on either side of plate.
 Mark the boundary of the plate on the skin.
 Place the vertical target on the plate
 Open shutter on laser.
 Align pelvic bracket so the laser beam projects crosshairs
on the vertical target mounted on the distal thigh and
remove vertical target.
NOTE: Ensure laser lens is clear. Close laser shutter when not in use.
WARNING:
 Discontinue use of laser if crosshair pattern is obscured.
 Discontinue use if unable to verify thigh plate is aligned with original
marking on skin or if unable to return it to original position.
Adjusting the Registration Jig
TIP: To adjust the laser alignment on the leg, loosen pelvic base locking screw, and adjust
angle of pelvic bracket.
Locking the Registration Jig
 Use the 3.5mm hex driver to lock screw tightly to secure
jig in this position for remainder of procedure.
 Close the shutter on the laser module.
WARNING: Ensure all connections and locking mechanisms are secure before proceeding with registrations.
How to Register Landmarks
INCORRECT:
TIP: Hold probe close to the tip
to maximize accuracy of point. TIP: When pressing buttons, support back of navigation unit to avoid flexing jig. If registration is not accepted, keep probe tip stationary and gently squeeze center button.

Registrations
Register Home
 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.

Thread the adapter into the acetabular shell.
Pull on the finger grip shown to release the adapter from the
impactor.
Following full seating of the shell, remove the impactor from the
implant adapter.
Use the socket driver to remove the adapter from the implant.
NOTE:
 Align the screw holes of shell as desired; Adapter can be assembled in multiple angles relative to the impactor.
 Vertical orientation of the Reference Sensor post is not required for accuracy; it is recommended for ease of use when
transferring the Reference Sensor to the impactor for navigation.
 If none of available adapters fits on selected implant, impactor cannot be navigated.
WARNING: Prior to impacting, verify shell is fully seated on shoulder of impactor and that threads do not protrude beyond
outer face of shell.
