How to measure the Centre Edge Angle of the hip joint with the CentreEdgeApp
The CE angle is one of the most frequently applied anatomic measures for the evaluation and description of the geometry of the hip in everyday orthopedic care. Measurements of CE angle in X-rays are valuable because you can determine and monitor objectively the severity of dysplasia, and establish the need for surgery and follow up the treatment.
Wiberg’s or center edge CE angle is formed at the juncture of the Perkin line with line drawn from the center of the femoral head to the outer edge of the acetabular roof. Measured on the Anterior Posterior hip radiographs the center edge angle is usually described as lateral center-edge angle LCEA or measured on the false-profile radiograph of the hip is described as the anterior center edge angle ACEA. The center edge angle may distinguish between acetabular insufficiency, under coverage or overcoverage of the femoral head by the acetabulum. The app is a handy tool for an orthopaedic surgeon, radiologist, medical student or resident who wants objectively to monitor and determine the severity of dysplasia of the hip. The build-in comparison feature with the normal reference values according to patient age may help decide what could be considered normal or dysplastic or pincer FAI. The app is not a simple goniometer, is an enhanced product which offers the ability to compare all the input data with medical reference database. The results are printed on the screen and the hips are categorized as normal or dysplastic or severe dysplastic or pincer FAI according to the angle measured. This feature it is particular useful especially in clinical settings where you need a quick results without losing time in looking for reference data according to age variations in huge textbook. The circular template to determine the points of interest and to mark them accurately are very useful in clinical settings where finding a sharpened pencil, a protractor and manage to draw with ruler lines over the patients x-rays is definitely a cumbersome and tedious task. You can load from your photo library or capture a photo from x-rays of the patient in you mobile phone or tablet, the App simply guides you to do the rest.Center-Edge Angle app is medical software aimed for orthopaedic surgeons
