cemented femoral stem
The LOGICA stem is a symmetrical (straight) stem that is available in two different versions: Logica Mirror for a cemented and CS for uncemented. Both versions are available in 7 sizes with a linear dimension progression, including offset and neck length.
The neck length increases according to the stem size (offset ranging from 40.5 to 48 mm), improving the articular range of motion (ROM) up to values of 136º thanks to the special tapered profile of the neck.
Only one instrument set, to be used with all Logica stems (cemented or cementless stems), allows for an intra-surgical choice of stems. The LOGICA stem has a medially rounded section with laterally prominent angles to adapt the stem profile to the femur and avoid stress shielding. Furthermore the macro-roughened surface facilitate osteointegration and biological fixation of the prosthesis
