Some hip problems that affect people later in life can stem from conditions that begin in infancy. Developmental dysplasia of the hip (DDH) is one such condition that affects how a baby’s hip joint develops. Because signs are not always obvious, early assessment matters. Read on to learn about hip dysplasia in babies, how it’s diagnosed, and how pediatric hip ultrasound helps with diagnosis.<\/span><\/p>\n

What Is Hip Dysplasia in Babies?<\/span><\/h2>\n

\"Normal<\/p>\n

 <\/p>\n

Hip dysplasia in babies, medically known as developmental dysplasia of the hip (DDH), is a condition in which the hip joint does not develop normally. In a healthy hip, the rounded head of the thighbone (femur) fits into a socket in the pelvis. With DDH, the socket may be too shallow to support the femoral head properly, or the joint may be unstable, allowing the bone to move partially or completely out of its normal position.<\/span><\/p>\n

DDH is commonly identified during infancy, although some cases are diagnosed later in childhood. The condition may be present at birth or become apparent as the hip develops. Because affected babies may not show obvious signs, regular hip examinations are important, and clinicians may recommend an infant hip ultrasound when further assessment is indicated. This examination uses a suitable pediatric ultrasound probe to help clinicians evaluate the developing hip joint. <\/span>In the following sections, we\u2019ll explore how this imaging technique helps clinicians evaluate the developing hip joint.<\/span><\/p>\n

Signs and Symptoms of Hip Dysplasia in Babies<\/span><\/h2>\n

\"Signs<\/p>\n

According to the International Hip Dysplasia Institute (IHDI), about 1 in 10 newborns<\/strong> has hip instability, and about 90% of these cases stabilize naturally after birth. However, early hip instability is not the same as the full spectrum of developmental dysplasia of the hip (DDH).<\/span><\/p>\n

The American Academy of Pediatrics (AAP) estimates that developmental hip dislocation occurs in approximately 1 in 1,000 live births<\/strong>. This figure refers to hip dislocation rather than all forms of DDH, which can range from mild abnormalities to complete dislocation.\u00a0<\/span><\/p>\n

So, what signs may indicate hip dysplasia in babies?<\/span><\/p>\n

DDH does not always show visible signs, so a baby may appear comfortable and move normally despite the condition. When signs are present, they may include:<\/span><\/p>\n
