Infant Hip Ultrasound

Infant hip ultrasound is one of the most important and precise methods for early detection of developmental dysplasia of the hip (DDH). This is a painless, safe, and short examination that allows verification of proper hip joint development in the first weeks after birth. Since it is performed using ultrasound, the examination uses no radiation and is completely safe for newborns.

Regular hip ultrasound is recommended for every newborn, as timely diagnosis prevents later complications, walking development problems, pain, and need for surgical interventions.

What is Infant Hip Ultrasound?

Hip ultrasound is a diagnostic examination that shows:

• Development of hip joints in newborns and infants,
• Position of the femoral head (thigh bone) relative to the joint,
• Cartilage condition,
• Joint stability and depth,
• Potential signs of hip dysplasia, instability, or underdeveloped joint.

This examination is standard in pediatric and neonatal medicine, as it enables identification of deviations in the earliest phase—when treatment is simplest, shortest, and most successful.

Why is Hip Ultrasound So Important?

Developmental hip dysplasia is a condition that often cannot be recognized by the naked eye. The baby may appear completely normal, but the hip joint may be immature or shallow. If not discovered in time, it can later lead to:

• Irregular walking development,
• Hip and back pain,
• Limited movements,
• Early arthritis,
• Need for long-term treatment or surgery.

Early detection = simple, quick, and successful treatment.

When is Infant Hip Ultrasound Performed? – Recommended Schedule

The best time for the first hip ultrasound is:

• Between the 4th and 6th week of life (standard recommendation),
• Earlier for babies with risk factors.

Follow-up examination is performed:

• Around 3 months,
• Or on orthopedist/physiatrist recommendation.

With normal findings, further follow-up is often not needed.

Which Babies are in the Risk Group and Need Earlier Ultrasound?

Babies have increased risk for developmental hip dysplasia if:

• They were in breech (pelvic) position during pregnancy,
• There is family history of hip dysplasia,
• They are twins,
• They have limited movement in one leg,
• The pediatrician hears or feels a “click” in the hip,
• They have foot deformities, torticollis, or other orthopedic anomalies.

For these babies, ultrasound may be recommended as early as the first 10–14 days.

How Does Infant Hip Ultrasound Look?

The examination is completely painless and lasts only a few minutes:

• The baby is placed on their back and side.
• The physician applies warm gel to the hip area.
• The probe displays the hip joint structures.
• The examination is performed on both sides.
• Findings are available immediately with parental advice.

No preparation is needed, and parents can be completely relaxed—most babies sleep through the examination calmly.

What Can Infant Hip Ultrasound Detect?

The examination enables detection of:

• Developmental hip dysplasia,
• Shallow or immature hip,
• Joint instability,
• Changes in femoral head position,
• Hip development asymmetry.

All this is discovered before the baby starts standing or walking, enabling timely therapy.

How is Hip Dysplasia Treated if Detected?

If ultrasound shows deviation, the most common recommendations are:

• Wide swaddling,
• Wearing Pavlik harness,
• Physical therapy (as assessed),
• Regular check-ups every 4–8 weeks.

In over 95% of cases, if detected early, therapy is short and successful.

Advantages of Infant Hip Ultrasound

• Completely safe (no radiation),
• Quick and painless,
• Extremely precise for early diagnosis,
• Ideal for development monitoring,
• Enables prevention of long-term walking problems,
• Best method for detecting developmental hip dysplasia.

Most Common Questions (FAQ)

Does hip ultrasound hurt the baby?
-No, the examination is completely painless and gentle.

How long does hip ultrasound last?
-Usually 5–10 minutes.

Is special preparation needed?
-No, none is needed. It is recommended that the baby be calm and fed.

Can hip dysplasia be seen only by pediatrician examination?
-Not always. Therefore, ultrasound is the gold standard.

How many times is hip ultrasound performed?
-Once, and follow-ups are done only if there is deviation.
