What is Hip Dysplasia? Early Diagnosis and Treatment in Children

 Developmental Dysplasia of the Hip (DDH), commonly called hip dysplasia, is one of the most frequently treated lower limb conditions in pediatric orthopedics. This condition occurs when the hip joint does not develop normally in babies or young children, which can lead to instability or dislocation of the hip joint.



If detected early, hip dysplasia can be treated successfully and long-term complications can be prevented. Consulting an experienced pediatric orthopedic surgeon plays a vital role in early diagnosis and proper treatment.

Understanding the Hip Joint

The hip joint is a ball-and-socket joint.

  • The ball is the top portion of the thigh bone (femoral head).

  • The socket is part of the pelvic bone called the acetabulum.

In a healthy hip, the ball fits securely into the socket, allowing smooth movement.

In hip dysplasia, the socket is too shallow, which means the ball cannot fit properly inside it. This can cause the hip joint to become unstable.

Hip dysplasia exists on a spectrum of severity, including:

  • Mild hip instability

  • Shallow hip socket

  • Partial hip dislocation

  • Complete hip dislocation at birth

If untreated, mild dysplasia can lead to painful hip arthritis later in adulthood.

Why Early Diagnosis is Important

Early diagnosis is one of the most important factors in the successful treatment of developmental dysplasia of the hip.

When hip dysplasia is detected in early infancy, treatment is usually simple and non-surgical. Early management helps guide the hip joint to develop normally and prevents future complications.

Delays in diagnosis may lead to:

  • Difficulty walking

  • Hip pain later in life

  • Joint damage

  • Need for surgery

Regular newborn screening and pediatric orthopedic evaluation help detect the condition early.

How Common is Hip Dysplasia?

Hip dysplasia is a relatively common condition in newborns.

Studies show that:

  • 1 in 100 babies requires treatment for hip dysplasia.

  • 1 in 500 babies is born with a completely dislocated hip.

Several risk factors increase the chances of hip dysplasia.

Family History

Children are at higher risk if a close family member, such as a mother, sibling, or aunt, had hip dysplasia or required hip treatment in childhood.

Breech Position During Pregnancy

When the baby is in a breech position (bottom down and head up) towards the end of pregnancy, the hips may be placed under pressure, increasing the risk of hip instability.

Tight Position in the Womb

Some babies develop conditions caused by limited space in the uterus, such as:

  • Plagiocephaly (flattened head)

  • Torticollis (stiff neck)

  • Foot abnormalities

These conditions can sometimes occur along with hip dysplasia.

Other Factors

Hip dysplasia is also more common in:

  • Girls

  • First-born babies

However, it is important to note that up to 50% of babies with hip dysplasia may not have any identifiable risk factors.

How is Hip Dysplasia Detected?

The best tool for early diagnosis of hip dysplasia in infants is a hip ultrasound scan.

Doctors usually recommend performing the ultrasound when the baby is 4–6 weeks old.

Scanning too early, such as within the first few days of birth, may sometimes over-diagnose hip dysplasia because the hip joint continues developing during the first few weeks of life.

Selective Screening

Many healthcare systems perform selective screening for babies with risk factors such as:

  • Family history of hip dysplasia

  • Breech presentation during pregnancy

During the ultrasound:

  • The baby is positioned on their side

  • Each hip is scanned individually

  • The stability and shape of the socket are evaluated

Doctors measure an important parameter called the Alpha angle, which helps determine whether treatment is required.

If the ultrasound results are normal, the baby usually does not need further follow-up.

Treatment of Hip Dysplasia in Infants

When hip dysplasia is diagnosed early, treatment is usually non-surgical.

Pavlik Harness Treatment

The most common treatment for infants younger than six months is the Pavlik harness.

The Pavlik harness is a soft brace that:

  • Keeps the baby's hips in a safe position

  • Allows natural movement

  • Helps the hip joint develop correctly

The harness gently positions the baby's legs outward and bent, which is the most stable position for the hip joint.

Babies usually wear the harness for about 23 hours per day, removing it only briefly for bathing.

Regular follow-up visits allow the pediatric orthopedic surgeon to:

  • Adjust the harness

  • Monitor hip development

  • Ensure the treatment is progressing well

Most babies respond very well to this treatment when diagnosed early.

What Happens if the Harness Does Not Work?

In some cases, especially when the child is older than six months or the hip remains dislocated, additional treatment may be necessary.

Doctors may perform a procedure called an arthrogram, where a contrast dye is injected into the hip joint under anesthesia. This allows doctors to clearly see the hip structure on imaging.

Depending on the findings, treatment may include:

Closed Reduction

The doctor gently moves the hip joint back into the socket without open surgery.

Hip Spica Cast

After repositioning the hip, a hip spica cast is applied to keep the hip stable while it heals and develops normally.

The cast is usually worn for several weeks and may require follow-up imaging to ensure stability.

Surgical Treatment

If the hip cannot be stabilized through non-operative methods, surgery may be required to correctly position the hip joint.

The goal of surgery is to restore normal hip alignment and prevent long-term complications.

When Should Parents Consult a Pediatric Orthopedic Specialist?

Parents should seek medical advice if they notice:

  • Uneven leg lengths

  • Limited movement of one leg

  • Asymmetrical thigh folds

  • A clicking sound in the hip

  • Delayed walking

Early consultation ensures timely treatment and better outcomes.

Introduction:  Bow legs, medically known as genu varum, is a condition characterized by outward curvature of the legs, causing them to bend outward at the knees while the feet and ankles are together. While mild bow legs are common in infants and toddlers, persistent or severe cases may require medical intervention. In this blog, we'll delve into the causes, symptoms, and treatment options for bow legs. Causes of Bow Legs: Normal Development:  Bow legs are common in infants and toddlers as a normal part of development. Babies are born with bow legs due to the positioning in the womb, and the legs gradually straighten as they grow and start walking. Nutritional Deficiencies: In some cases, bow legs may result from nutritional deficiencies, particularly vitamin D and calcium, which are essential for healthy bone growth and development. Blount's Disease:  Blount's disease is a rare growth disorder that affects the growth plates in the shinbone (tibia), leading to abnormal bo...
