As a new parent, navigating the world of infant health screenings can feel overwhelming. Among the various checks your baby will receive, one that deserves particular attention is screening for Developmental Dysplasia of the Hip (DDH). This condition, while potentially serious, is highly manageable when detected early. This blog will explain what DDH is, why early screening is vital, and how proactive care can ensure your child’s healthy development.
What is Developmental Dysplasia of the Hip (DDH)?
Developmental Dysplasia of the Hip refers to a spectrum of conditions where a baby’s hip joint does not form properly. In a healthy hip, the rounded top of the thigh bone (femoral head) fits snugly into the hip socket (acetabulum). In DDH, this socket may be too shallow, or the ligaments may be loose, allowing the femoral head to slip partially or completely out of place. This can range from mild instability to a complete dislocation.
DDH is not always present at birth; it can “develop” during the first year of life, hence the term “developmental.” It is one of the most common congenital conditions, affecting approximately 1 to 3 of every 1,000 babies. Girls, first-born children, babies born in the breech position, and those with a family history are at a higher risk.
Why is Early Screening for Hip Dysplasia So Crucial?
The first few months of a baby’s life are a period of rapid growth and development. This is a critical window for the hip joint. Cartilage is still soft and moldable, making non-surgical correction not only possible but highly effective.
-
Prevents Long-Term Complications: Undiagnosed and untreated DDH can lead to significant problems as a child grows. These include a limp, leg length discrepancy, hip pain, and early-onset arthritis, often requiring major surgery in adolescence or adulthood.
-
Enables Simpler, Non-Surgical Treatment: When detected early (within the first 6 months), DDH can often be treated with non-invasive methods. The most common is a soft brace, like the Pavlik harness, which holds the baby’s hips in a stable, flexed position, allowing the socket to develop normally around the femoral head. Success rates for harness treatment are excellent when started early.
-
Avoids Complex Surgery: Late diagnosis (after 6-12 months) often means the child will require closed or open surgical procedures under anesthesia, followed by months in a spica cast. These treatments are more invasive, stressful for the family, and have longer recovery times.
-
Promotes Optimal Development: A stable hip joint is foundational for reaching motor milestones like rolling over, sitting, crawling, and walking. Early treatment ensures your child can develop these skills on schedule.
Screening typically involves a physical examination where the pediatrician performs specific maneuvers (like the Ortolani and Barlow tests) to check for hip stability. For high-risk infants or those with inconclusive exams, an ultrasound of the hip is the gold standard diagnostic tool before 6 months of age.

FAQs on Hip Dysplasia
1. What are the signs of hip dysplasia in babies?
Common signs include uneven thigh or buttock skin folds, limited movement in one hip, a “clicking” or “clunking” hip sound, and, in older infants, a limp or walking on toes on one side.
2. Can hip dysplasia correct itself?
Mild instability may resolve on its own in the first few weeks. However, true dysplasia or dislocation will not self-correct and requires medical intervention to ensure proper joint development.
3. How is hip dysplasia treated in infants?
The primary treatment for infants under 6 months is a soft positioning brace like a Pavlik harness. For older babies or more severe cases, treatment may involve a closed reduction (manually repositioning the hip) or surgery, followed by a period in a cast.
4. What causes hip dysplasia in infants?
The exact cause is often multifactorial, involving genetic predisposition (family history), hormonal factors that loosen joints, and mechanical factors like a breech position in the womb or swaddling with legs straight and tight.
5. When should a baby be screened for hip dysplasia?
All newborns should receive a clinical hip exam at birth and at every well-baby check-up until they are walking confidently. High-risk babies often require an ultrasound screening between 4-6 weeks of age.
