Placement of the standard polyethylene insert using the inserter/impactor To position the polyethylene insert, it is recommended to use the inserter/impactor (130818). The inserter/impactor must be reassembled to do so. Screw the adapter for the PE insert and the impactor head onto the inserter/impactor. Retract the internal section of the inserter/ impactor and mount the PE insert on the three nipples. Important The Rexpol inserts, diameter 36 mm, Art. No. 11000310–311, are not compatible with the positioning and striking device and require the Octoplus, Art. No. 1150126, positioning device or can be inserted manually. Insert the PE in the shell by impacting the inner section of the inserter/impactor. Optionally Check the fit of the PE insert in the shell using a raspatory. Note The PE insert must not be reused. Rim osteophytes must be carefully removed to prevent anterior or lateral impingement, tendencies to dislocation or restriction of movement. 12
Insertion of the hooded polyethylene insert using the inserter/impactor It is recommended to insert the hooded polyethylene insert using the inserter/impactor (130818). The procedure for the hooded polyethylene insert and the inserting device is analogous to the description under “Placement of the standard polyethylene insert using the inserter/ impactor”. Note The position of the shoulder of the hooded PE inserts can be changed in 30º increments. Use of the BIOLOX ® forte/delta ceramic insert Indications and contraindications The same indications and contraindications apply to the use of the BIOLOX ® forte/delta cup inserts as for total hip arthroplasty with other articulating surfaces. The following additional contraindications apply to ceramic inserts: • The inclination should not be substantially above or below the range 40–50º. • The anteversion must not be above or below the range 10–20º. • If the angle of inclination is below 30º or above 50º BIOLOX ® forte/delta inserts must not be used. Smith&Nephew Orthopaedics standard and hooded PE inserts are available for such cases. • Ceramic cup inserts should similarly not be used for cups in a retroversion mode. • Risk of impingement should at all times be avoided. Implantation A trial insert should be used before a ceramic insert is implanted. Trial heads of the intended diameter must then be used to ensure an adequate range of motion (ROM) in all directions and to check the stability of the joint. The artificial joint must not dislocate in the course of movement or subluxate through impingement of the implant components or soft tissue. The alignment guide (130728) should always be used with BIOLOX ® forte/delta ceramic inserts in order to obtain the necessary level of accuracy. It is advisable to use computer-assisted navigation systems intraoperatively for documentation and verification of the implant position and to get exact information on the ROM. 13
