Which of the following is a common postural deformity involving the hip?

• A. Rotational deformities of the hip
• B. Hyperextension of the knee
• C. Plantarfaciitis
• D. Tibial torsion

Answer: (A)

Postural deformities at the hip most often involve rotation of the femur, producing abnormal hip alignment. Muscle imbalances and altered tone around the hip can cause the thigh to rotate inward or outward, so you see a pattern where the leg turns in or out when the person stands or walks. This rotational issue is a classic hip postural deformity, and it can contribute to an in-toeing or out-toeing gait.

The other options involve different joints or parts of the leg. Hyperextension of the knee is a knee joint issue, plantar fasciitis is a foot/heel problem, and tibial torsion is rotation of the tibia (the shinbone), not the hip. So rotational deformities of the hip best describe a common hip-related postural deformity.
