Use the U-Motion II Drill Guide, Drill Bit, and Modular Flex Shaft for drilled hole preparation. The lengths of four Drill Bits are 15, 25, 35 and 50 mm. Carefully drill into acetabulum within selected holes, utilize the Depth Gauge to determine an appropriate screw length. Apical Hole Plugging All U-Motion II acetabular cups can be implanted using the same surgical technique guide. While handling the cup prosthesis, at the proper position and alignment, strike the U-M II Cup Impactor with a mallet until the cup is fully seated. By sighting through the apical hole or screw holes if present, confirm whether a congruent contact between bone- implant interface is achieved. An apical hole cover among the Screw-Hole Cover set is then plugged with a hex head Straight Screwdriver by the Ratchet Handle following cup seating. Supplementary threaded covers are prepared for residual screw holes as well. Cup Insertion Instruments D.
