Wiberg Center-Edge Angle and Hip Dysplasia Severity

Calculate lateral center-edge angle (LCEA, Wiberg angle) and anterior center-edge angle (ACEA) from hip radiographs to grade acetabular dysplasia. LCEA <20 degrees = dysplasia, 20-25 = borderline, >25 = normal.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate lateral center-edge angle (LCEA, Wiberg angle) and anterior center-edge angle (ACEA) from hip radiographs to grade acetabular dysplasia. LCEA <20 degrees = dysplasia, 20-25 = borderline, >25 = normal

Each component has a specific meaning:

  • Hip radiographs — The hip radiographs recorded for the scenario being assessed.

Note: Interpret the wiberg ce angle hip result against the thresholds and context described above.

How to Use

Enter the hip radiographs for the scenario you are assessing. Calculate lateral center-edge angle (LCEA, Wiberg angle) and anterior center-edge angle (ACEA) from hip radiographs to grade acetabular dysplasia. LCEA <20 degrees = dysplasia, 20-25 = borderline, >25 = normal. Use the wiberg ce angle hip result to inform your calculation.
