Question:easy
Which of the following attitude will be seen in a patient with posterior dislocation of the hip?
Which of the following attitude will be seen in a patient with posterior dislocation of the hip?
Show Hint
Posterior hip dislocation - limb is flexed, adducted, internally rotated and shortened.
Updated On: Jun 23, 2026
- Flexion, Abduction, Internal rotation
- Flexion, Adduction, Internal rotation
- Flexion, Abduction, External rotation
- Flexion, Adduction, External rotation
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Classify hip dislocations by the direction of femoral head displacement - posterior is the commonest pattern, usually from a dashboard-type force along a flexed knee.
Step 2: When the head sits behind the acetabulum, the limb assumes a characteristic posture of flexion at the hip, adduction across the midline, and internal rotation, with apparent limb shortening.
Step 3: Compare with the anterior type, which produces abduction and external rotation - the reverse of the posterior attitude - and the central type, which shows medial trochanter displacement without shortening.
Step 4: Matching the posterior pattern gives flexion + adduction + internal rotation. \[\boxed{\text{Flexion, Adduction, Internal rotation}}\]
