Developmental Dysplasia of the Hip (DDH)

Developmental dysplasia of the hip, also known as DDH, is a condition in which an infant's hip joint does not form properly. This can occur before birth or during early childhood.

• Causes: The exact cause of DDH is often unknown, but it may be related to genetic factors, hormonal influences, or environmental factors.
• Symptoms: Infants with DDH may exhibit a range of symptoms, including:
  • A distinct waddling gait
  • One hip lower than the other
  • A limp
  • Walking on tiptoe

Prevalence and Diagnosis

DDH is relatively common, occurring in about 1 in every 1000 live births. Early diagnosis and treatment are crucial to prevent long-term complications.

• Risk factors: Certain risk factors may increase the likelihood of DDH, including:
  • Family history
  • Premature birth
  • Low birth weight

Treatment Options

Treatment for DDH typically involves a combination of conservative and surgical approaches. The goal is to stabilize the hip joint and promote normal growth and development.

• Conservative treatment: This may include physical therapy, bracing, or other non-surgical interventions.
• Surgical treatment: In some cases, surgery may be necessary to correct the dislocation and ensure proper hip joint formation.

Developmental Dysplasia of the Hip (DDH) Signs and Symptoms

Developmental dysplasia of the hip, also known as DDH, is a condition where the hip joint does not form properly. This can lead to various signs and symptoms, which can vary depending on the age group affected.

• Hip pain: One of the most common symptoms of DDH is hip pain, usually felt in the front of the groin area.
• Feeling of loose or unstable hip: People with DDH may experience a feeling of looseness or instability in their hip joint.
• Limping: As the condition progresses, individuals may develop a limp when walking or moving.

These symptoms can be present from birth to adulthood. In infants, the signs and symptoms may include:

• One leg being longer than the other
• A distinct waddling gait
• One hip lower than the other
• A limp
• Walking on tiptoe

In older children and adults, the symptoms may include:

• Pain in the groin area that increases with activity
• Limping
• A catching, snapping or popping sensation in the hip joint
• Loss of range of motion in the hip joint

It's essential to seek medical attention if you or your child experience any of these symptoms. Early detection and treatment can significantly improve outcomes.

Diagnostic Tests for Developmental Dysplasia of the Hip

Developmental dysplasia of the hip (DDH) can be diagnosed through various tests, which vary depending on the age of the patient. Here are some common diagnostic tests used to diagnose DDH:

• Serial physical examination: This is the primary method for diagnosing DDH in infants [2]. Regular physical examinations by a healthcare provider can help detect any abnormalities in the hip joint.
• Imaging tests: Imaging tests such as X-rays, magnetic resonance imaging (MRI), and ultrasound are used to confirm the diagnosis of DDH. These tests can provide detailed images of the hip joint and surrounding tissues.
• Ortolani and Barlow tests: These two physical examination tests are commonly used to assess the stability of the hip joint in infants [4]. The Ortolani test involves gently moving the infant's leg to check for any instability, while the Barlow test involves applying a gentle force to the leg to see if it dislocates.
• Ultrasound: Ultrasound is often used in patients less than 6 months of age to diagnose DDH [6]. This non-invasive imaging test uses high-frequency sound waves to produce images of the hip joint and surrounding tissues.

These diagnostic tests can help healthcare providers confirm a diagnosis of developmental dysplasia of the hip, which is essential for developing an effective treatment plan.

Treatment Options for Developmental Dysplasia of the Hip (DDH)

While surgery is often required to correct DDH, especially in older children and young adults, there are some cases where mild forms of the condition can be corrected with time. In infancy, a soft brace may be used to correct the condition.

However, it's essential to note that not all cases of DDH can be treated with non-surgical methods. The effectiveness of these approaches depends on various factors, including the severity of the condition and the age of the child.

Non-Surgical Treatment Options

• In some cases, mild forms of DDH in infants may correct themselves with time.
• A soft brace may be used to help correct the condition in infancy.

Surgical Treatment Options

• Older children and young adults often require surgery to correct DDH.
• The goal of surgical treatment is to restore a normal hip joint, ensuring proper alignment and function.

It's crucial to consult with a healthcare professional for an accurate diagnosis and personalized treatment plan. They can assess the severity of the condition and recommend the most effective course of action.

Differential Diagnosis of Developmental Dysplasia of the Hip

Developmental dysplasia of the hip (DDH) encompasses a spectrum of disease that includes dysplasia, shallow or underdeveloped acetabulum, subluxation, displacement of the joint with some contact, and complete dislocation. When considering differential diagnoses for DDH, several conditions should be taken into account.

• Various teratologic hip disorders: These are rare congenital anomalies that can mimic DDH.
• Proximal femoral focal deficiency (PFFD): A rare condition characterized by a short or absent proximal femur, which can lead to DDH-like symptoms.
• Septic hip: Infection of the hip joint can cause inflammation and potentially lead to dislocation, making it a differential diagnosis for DDH.

Key Points

• DDH is a spectrum of disease that includes dysplasia, subluxation, and complete dislocation.
• Various teratologic hip disorders, PFFD, and septic hip are potential differential diagnoses for DDH.
• Accurate diagnosis requires a thorough evaluation of the patient's symptoms and medical history.
