The center edge angle of wiberg used to assess?
The center-edge angle (CE angle) of Wiberg is a radiographic measurement used to assess the development and stability of the hip joint, particularly in cases of hip dysplasia. It is a key measurement used in the diagnosis and treatment planning for developmental dysplasia of the hip (DDH).
The CE angle is measured on an anteroposterior (AP) radiograph of the pelvis, and it represents the angle between two lines: one drawn from the center of the femoral head to the lateral edge of the acetabulum (the cup-shaped socket in the pelvis that the femoral head fits into), and another line drawn perpendicular to the line that bisects the acetabulum. A normal CE angle is typically between 20 and 40 degrees, with higher values indicating a more shallow or dysplastic acetabulum and increased risk of hip dislocation.
The CE angle is named after Per Wiberg, a Swedish radiologist who first described the angle in 1939. It is widely used in clinical practice to assess hip joint morphology and stability, particularly in infants and children who may be at increased risk of hip dysplasia or dislocation. The CE angle can help guide treatment decisions, such as the use of braces, casts, or surgical interventions to improve hip joint stability and prevent long-term complications.
