Anatomy · Lower limb: pubofemoral ligament
Sample itemDuring hip examination, extreme abduction is limited by tension in a ligament that passes from the pubic part of the acetabular rim to the intertrochanteric line below. Which ligament is it?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Pubofemoral ligament
The pubofemoral ligament runs from the superior pubic ramus and obturator crest to the intertrochanteric line and neck. It limits excessive abduction and extension. The iliofemoral ligament mainly resists hyperextension, and the ischiofemoral ligament limits medial rotation.
Option by option
A. Ligament of the head of the femur
The ligament of the head is slack in most positions and gives little mechanical restraint.
B. Ischiofemoral ligament
The ischiofemoral ligament lies posteriorly and limits medial rotation.
C. Iliofemoral ligament
The iliofemoral ligament is the strongest and chiefly resists hyperextension.
D. Pubofemoral ligament (correct)
Correct. The pubofemoral ligament tightens in abduction.
