Vantaggi della modularità del collo negli steli femorali
di scegliere la taglia dello stelo che meglio si adatta al femore
indipendentemente dalla necessità di correggere off-set e dismetria.
Una volta impiantati il cotile e lo stelo definitivi il chirurgo,
guidato dalla pianificazione preoperatoria, può testare il sistema
modulare che meglio ricostruisce la biomeccanica articolare valutando
la stabilità dell’impianto e la dismetria.
L’adeguato ripristino della cinematica articolare determina una
maggiore stabilità dell’impianto, riduce le possibilità di fallimento
e, migliorando l’efficienza degli abduttori, migliora i risultati clinici
della chirurgia protesica.
