[A new type of iliac fracture caused by bone insufficiency]. / Un nouveau type de fracture iliaque par insuffisance osseuse.

ABSTRACT

BACKGROUND: The iliac bone is an uncommon localization for bone insufficiency fractures. We report a new type. CASE REPORT A 51-year-old woman with post-menopause osteoporosis was seen for a fracture of the ischio-pubic branch of the iliac bone. X-ray also revealed an unknown fracture situated above the anterior superior iliac spine continuing cranially and medially towards the iliac crest. DISCUSSION: Three types of iliac fractures due to bone deficiency have been described. Type 1, (oblique iliac), the fracture is oblique beginning in the greater sciatic notch and extending a more or less into the iliac wing. Type 2 (superior medial iliac) involves the most medial part of the iliac wing, approximately parallel to the sacroiliac joint. In type 3 (supra-acetabular), the fracture is in a supra-acetabular localization. Our case suggests a fourth type should be individualized.
