Which of the following attitude will be seen in a patient with posterior dislocation of hip?
**Core Concept**
The **posterior dislocation of the hip** is a serious injury that occurs when the head of the femur is forced out of the acetabulum in a posterior direction. This type of dislocation is often associated with a specific attitude of the lower limb. The **femoral head** and **acetabulum** relationship is crucial in understanding the resulting position of the limb.
**Why the Correct Answer is Right**
In a **posterior dislocation of the hip**, the limb is typically found in a position of **flexion**, **internal rotation**, and **adduction** due to the direction of the dislocation and the muscles involved. This position results from the **hamstring** and **adductor** muscles pulling the femur posteriorly, and the **piriformis** muscle contributing to the internal rotation.
**Why Each Wrong Option is Incorrect**
**Option A:** This option does not accurately describe the typical position seen in posterior hip dislocation.
**Option B:** Similarly, this option is not characteristic of the limb position in posterior hip dislocation.
**Option C:** This is not the correct attitude for posterior dislocation.
**Option D:** Although not specified, any option not describing flexion, internal rotation, and adduction would be incorrect.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **posterior hip dislocations** are more common than anterior dislocations and often require urgent reduction to prevent **avascular necrosis** of the femoral head.
**Correct Answer:** D. Flexion, internal rotation, and adduction.
