Remove any peripheral osteophytes and resect the labrum. Make sure to remove any posterior and inferior osteophytes that could hinder cup placement. Prepare the acetabulum using the reamers starting with the smallest acetabular reamer available. The reamers can be used with either a straight or offset reamer handle. Gradually increase the reamer diameter until good peripheral support is achieved and bleeding subchondral bone has been exposed. Make sure not to go past the acetabular fossa (external lamina). The reamed cavity must be completely circular. Clean out the bottom of the...

Assemble the trial cup on the impactor (straight or curved). The chosen trial cup size must be based on the last reamer used (see next page). Make sure the trial cup is completely screwed to the impactor handle. The trial has the same dimensions as the implant, without press-fit. The cup orientor can be placed on the impactor being used, to set a 45° angle relative to the vertical plane. Clean out the bottom and rim of the acetabulum to prevent small bone or tissue fragments from interfering with cup impaction. Impact the trial cup while maintaining the inclination and anteversion providing...

Reaming must be performed using even reamers, by size increment (2 mm). The size of the last validated reamer (see p.9) determines the size of the trial cup. The size is validated if the trial is stable in the acetabulum, and introduced without need of impaction. If the trial must be impacted, the following techniques can be followed:  Ream the equator of the acetabulum one size over (2 mm). Ream the whole acetabulum half a size over (1 mm): those reamers are available on request only. Ø52 Reamer Ø52 Trial Must be impacted Acetabulum equator Ø52 Trial Stable without impaction General...

Take the final cup of the same size as the trial cup out of its packaging. Screw the expandable impaction tip of the same size as the final cup on the impactor handle. Place the chosen cup on the impaction tip, making sure that the entire periphery of the cup makes contact with the rim of the impaction tip. With the straight impactor With the curved impactor Turn the yellow handle to the right to expand the impaction tip, until complete grip of the implant. Close the blue lever completely to achieve complete grip of the implant. NOTE Assembly instructions of the impactors are available in...

Place the alignment guide on the impactor handle (clipped on the straight impactor, screwed on the curved impactor). Place the chosen cup in the reamed acetabulum at the predefined inclination and anteversion, and then impact it. Remove the impactor handle: With the straight impactor Turn the yellow handle to the left. With the curved impactor Open the handle. NOTE If needed, the cup can be realigned using the dedicated cup realignment tip.

Prepare the femur by following the surgical technique for the chosen stem. Select the trial liner for dual mobility cup of the same size as that of the final cup, and one that corresponds to the desired femoral head size. Trial heads and liners color code Green Trial heads neck length code* Short neck Medium neck Long neck Extra-Long neck Perform mobility and stability trials with the femoral stem in place. Remove trial components when stability is validated. NOTE The trial liners for size Ø48 mm and beyond are intended to be used with Ø28 mm femoral heads. If performing trials with Ø22.2...

Holding handle Baseplate Secure the handle and the baseplate on the dual mobility cup press. Fully loosen the yellow T-handle. Place a femoral head of the size chosen during the trials on the baseplate. Select the liner that matches the size chosen during the trials. Place the liner on the head and turn the Thandle on the press until the liner’s retaining mechanism has been cleared. An audible noise indicates that the head has moved into the liner and is correctly seated. Turn the T-handle one or two more times to eliminate any air caught in the liner. Make sure the head can move within the...
