Damage to the obturator artery most commonly occurs from the placement of an inferior retractor inferior to the transverse acetabular ligament (into the obturator foramen), and/or placement of an acetabular screw in the anterior-inferior quadrant.

Vascular injury during total hip arthroplasty is a rare but devastating complication with a reported incidence of 0.1%-0.2%. The obturator artery travels along the quadrilateral surface of the acetabulum and exits the pelvis at the superolateral corner of the obturator foramen. If the vessel is severely damaged and bleeding cannot be controlled, ligation of the internal iliac artery has been reported.
