Figure 2. Portals: 1) anterolateral (ALP): upper margin of the greater trochanter in line with its anterior margin or 1 cm anterior and 1 cm superior to the tip of the greater trochanter; 2) middle anterior portal (MAP): 6-7 cm distal to the anterolateral portal, at an angle of about 60-70º; 3) distal anterolateral access (DALA): 3-4 cm distal and 1-2 cm anterior to the ALP; 4) proximal middle anterior portal (PMA): 2-3 cm proximal and 2-3 cm posterior to the MAP; 5) accessory DALA: 2-3 cm anterior to the standard DALA; 6) posterolateral portal (PLP): upper margin of the greater trochanter in line with its posterior margin or 1 cm posterior and 1 cm superior to the tip of the greater trochanter. The asterisk shows the zone of the greater trochanter.
