Attitude of lower limb seen in posterior dislocation of hip is?
**Core Concept:** Posterior dislocation of the hip is a dislocation of the hip joint in which the femoral head moves posteriorly and inferiorly relative to the acetabulum. This type of dislocation can be caused by high-energy trauma, such as motor vehicle accidents or falls from great heights.
**Why the Correct Answer is Right:** In a posterior dislocation of the hip, the femoral head moves posteriorly and inferiorly due to the disruption of the joint capsule and ligaments, primarily the capsule and the joint-stabilizing function of the iliopsoas muscle. The correct answer, **Answer Text**, describes the typical attitude of the lower limb in this condition:
**Why Each Wrong Option is Incorrect:**
A. False - The correct answer explains the typical attitude of the lower limb in a posterior dislocation.
B. False - The correct answer explains the typical attitude of the lower limb, not the displacement direction.

D. False - The correct answer explains the typical attitude, not the direction of displacement.

In addition, the patient should be evaluated for associated injuries and managed appropriately.
