Jennifer undergoes a pelvic scan to determine if she sustained any fractures as a result of a car accident. To her surprise, the technician does not find any fractures. He does note, however, that Jennifer's acetabulae are markedly shallow bilaterally. What might the technician conclude about Jennifer's pelvic bone structure, as a result of this finding?
What will be an ideal response?
The technician should explain to Jennifer that she may have rather flexible hip joints. As the head of the femur fits into the acetabulum of the coxal bone, the ligament of the femoral head and the bones of the acetabulum limit the movements of the femur in such an articulation. Since Jennifer's acetabulae are shallow, this limiting factor would be reduced. Thus, the increased flexibility may have prevented any fractures during the accident.
