Note

If the C-clamp is positioned too far ventral in the ilium, there may be perforation of this thin part of the ilium or internal rotation of the pelvic ring (A).

If the C-clamp is positioned too far posterior in the ilium, the result will be an external rotation widening of the pelvic ring (B).

Caudal position increases risk of the pins passing through the greater sciatic foramen into the pelvis, injuring nerves and vessels (C).
