The intra-iliac segment is a long channel screw with better mechanical properties over classic SIS.īousbaa H, Ouahidi M, Louaste J, Bennani M, Cherrad T, Jezzari H, Kasmaoui EH, Rachid K, Amhajji L (2017) Percutaneous iliosacral screw fixation in unstable pelvic fractures. The AP-SIS channels of S1-2 have sufficient width and length to accommodate a cancellous screw with a Φ 7.0–8.0 mm and a length 90–130 mm.
All parameters showed significant sex-related differences ( p < 0.05). Of the L measures, the intra-iliac segment was slightly longer than the intra-sacral segment. The length ( L), width ( W), height ( H), cortical bone spacing ( M), camber angle ( E), anteversion angle ( F), cross-sectional safety angle ( P) and sagittal safety angle ( Q) of the channel were measured by CT or Mimics software. Pelvic CT scan data of 80 healthy adults (40 males and 40 females) with an average age of 45 years (range 20–70 years) were collected. This study aimed to radio-anatomically measure the parameters of the channel for anterior–posterior placement SIS (AP-SIS), which can be placed percutaneously with an aiming device. The outlet of the classic sacroiliac screw (SIS) cannot be precisely controlled by aiming devices, which may lead to malpositioned implants and neurovascular and visceral injury.
