Definition of Sidel's Sign
- Sidel's sign, also known as Siedel's sign, is not explicitly defined in the provided studies 1, 2, 3, 4, 5.
- However, it can be inferred that Sidel's sign is related to the diagnosis of hip instability or developmental dysplasia of the hip (DDH) in infants.
Diagnosis of Hip Instability
- Hip instability is a clinical sign that characterizes congenital dislocation of the hip 1.
- The diagnosis of hip instability can be made using clinical examination, ultrasonography, or a combination of both 1, 2, 4.
- Clinical examination can lead to considerable overtreatment, while ultrasonography can provide a more accurate diagnosis 2.
Ultrasonography in Diagnosing Hip Instability
- Ultrasonography is increasingly being used to complement clinical examination in assessing neonatal hip instability 2, 4.
- Dynamic ultrasound examination can reduce the treatment rate by over 40% compared to clinical examination alone 2.
- Graf's method is another ultrasonographic technique used to assess acetabular morphology and hip stability 4.
