ortolani and barlow maneuvers

3 min read 18-03-2025

The Ortolani and Barlow maneuvers are essential clinical tests used to screen infants for developmental dysplasia of the hip (DDH), a condition where the hip joint doesn't form properly. Early detection is crucial for successful treatment, making these maneuvers vital in pediatric orthopedics. This article will explore these maneuvers in detail, explaining their purpose, technique, and interpretation.

Understanding Developmental Dysplasia of the Hip (DDH)

Developmental dysplasia of the hip (DDH) encompasses a range of hip abnormalities, from mild instability to severe dislocation. The hip joint may be partially or fully dislocated, hindering normal development and potentially leading to long-term problems like gait abnormalities and osteoarthritis. DDH is more common in girls and can be associated with breech presentation during pregnancy, family history, and other factors.

The Barlow Maneuver: Dislocating the Hip

The Barlow maneuver is designed to assess the stability of the infant's hip joint by attempting to dislocate it. Here's how it's performed:

Position: Gently hold the infant supine, flexing their hips and knees to 90 degrees.
Technique: With one hand, stabilize the infant's pelvis. Using the other hand, gently adduct (bring together) the infant's thigh while applying downward pressure on the greater trochanter (the bony prominence on the outer thigh). The examiner is trying to gently push the femoral head out of the acetabulum (hip socket).
Positive Sign: A palpable "click" or "clunk" indicates that the femoral head has been dislocated from the acetabulum. This suggests hip instability. Note: The absence of a click does not rule out DDH.

The Ortolani Maneuver: Reducing the Hip

The Ortolani maneuver attempts to relocate a dislocated hip. It's performed immediately after the Barlow maneuver.

Position: The infant remains supine with hips and knees flexed at 90 degrees.
Technique: While stabilizing the pelvis, gently abduct (move apart) the infant's thigh. The examiner applies upward and outward pressure on the greater trochanter.
Positive Sign: A palpable "clunk" as the femoral head is relocated into the acetabulum indicates a positive Ortolani sign. This strongly suggests hip instability or dislocation. Again, the absence of a click does not rule out DDH.

Interpreting the Results

Both maneuvers should be performed gently and systematically. A positive Barlow or Ortolani sign warrants further investigation, usually with ultrasound or X-rays to confirm the diagnosis. These tests are screening tools, not diagnostic tests. A negative result does not guarantee the absence of DDH.

Other Clinical Findings

While the Ortolani and Barlow maneuvers are crucial, other clinical findings can also suggest DDH:

Asymmetry of thigh folds: Unequal skin folds on the inner thighs.
Limited hip abduction: Restricted ability to spread the legs apart.
Galeazzi sign: Unequal leg lengths when the knees are flexed.

When to Perform the Maneuvers

These maneuvers are typically performed during routine newborn examinations, ideally within the first few weeks of life. However, they can be performed at any age, though their accuracy decreases with increasing age.

Limitations of the Maneuvers

The Ortolani and Barlow maneuvers have limitations. They are most effective in newborns and young infants. Their accuracy decreases as the child gets older and the ligaments tighten. False-negative results are possible, emphasizing the importance of clinical vigilance.

Conclusion

The Ortolani and Barlow maneuvers are invaluable screening tools for early detection of DDH. While a negative result doesn't rule out the condition, a positive finding necessitates further investigation and timely intervention to ensure optimal hip development and prevent long-term complications. Early diagnosis is crucial for effective treatment and a positive outcome. Regular check-ups with a pediatrician are essential for all infants.
