Alpha angle (cam morphology) | Radiology Reference Article ...
2024年5月7日 · The alpha angle is a radiological measurement proposed for the detection of cam morphology, which is sometimes associated with femoroacetabular impingement (FAI). The term alpha angle is also used in a separate and unrelated context in the evaluation of developmental dysplasia of the hip (DDH) in children.
Alpha angle (developmental dysplasia of the hip)
2023年4月24日 · The alpha angle is a measurement used in the ultrasonographic assessment of developmental dysplasia of the hip (DDH). The term alpha angle is also used in a separate and unrelated context in the evaluation of femoroacetabular impingement.
Hip Dysplasia: What’s With All the Angles? - Miles4Hips
Lateral Center Edge Angle (LCEA) This is the most commonly measured angle to determine if a person has hip dysplasia. It measures how well the acetabulum (“hip socket”) covers the head of the femur (“ball” of the hip joint). Normal values are between 25-35 degrees < 20-25 degrees = hip dysplasia (shallow hip socket)
Developmental Dysplasia of the Hip - The Radiology Assistant
2017年12月1日 · The alpha-angle, which is a measurement of the bony roof of the acetabulum, mainly determines the hip type. Actually, for classification purposes the beta angle is only used to differentiate between type Ia and Ib (both normal hips) and between type IIc and type D)
Radiographic Parameters of Adult Hip Dysplasia - PMC
Imaging parameters used in the workup for hip dysplasia and BHD include the lateral center-edge angle, Tönnis angle, iliofemoral line, and presence of an upsloping lateral sourcil or everted labrum, among many others.
Femoroacetabular Impingement: Can the Alpha Angle Be …
At imaging, the abnormal morphology of the anterior femoral head–neck junction is best evaluated on the axial oblique plane. The alpha angle measurement is a commonly used method for this assessment. The alpha angle was first described by Notzli et al. in 2002 as an
Adult Hip Radiography: Lines and angles - ESSR 2017 EPOS
Projection: Cross-table lateral view of the hip. Measurement: Angle between a line along the femoral neck axis (A) and a line from the center of the femoral head to the transition of the femoral head into the femoral neck (neck radius exceeds head radius) (B). Criteria: Normal angle <55º. If > 55 degrees then associated with CAM type ...
Ultrasound screening for developmental dysplasia of the hip ...
alpha angle: measured between the bony acetabular roof and the vertical cortex of the ilium. The normal value is greater than or equal to 60 degrees. beta angle: measured between the vertical cortex of the ilium and the fibrocartilaginous labrum.
Measurement of the alpha angle of the hip. The alpha angle is …
The alpha angle is the measured angle between the line connecting the point of no sphericity of the femoral head from the center of the femoral head and the other line extending up to the...

Ultrasound provides a non-invasive and radiation-free way to visualize the soft tissues, cartilage, and bones in real time. The Graf method is the most widely used technique, where two critical angles—alpha (α) and beta (β)—are measured to assess the development of the acetabulum and classify the hip's condition.
