» The KYOCERA Initia femoral stem mated with KMTI CoCr (28-40mm) or BIOLOX® delta (28-40mm) femoral head.
The Cemented Hip Stem is intended for cemented applications.
The KMTI Tesera Trabecular Technology (T3) Acetabular Shell System is intended for cementless applications. In addition, the KMTI T3 Acetabular Shell and Universal Liners can be used with:
* The KYOCERA Initia femoral stem mated with KYOCERA CoCr (28—40mm) or BIOCERAM AZUL (28-40mm) femoral head.
* The KMTI femoral stem mated with KYOCERA CoCr (28—40mm) or BIOCERAM AZUL (28-40mm) femoral head.
» The KYOCERA Initia femoral stem mated with KMTI CoCr (28-40mm) or BIOLOX® delta (28-40mm) femoral head.
The Bipolar Head is for use in conjunction with KMTI femoral heads and femoral stems.
In addition:
* The KYOCERA 28mm CoCr and 28mm BIOCERAM AZUL femoral heads and Initia femoral stem can be used with the KMTI 28mm ID Bipolar Head.
