Background There is a wide discrepancy in reported prevalence rates for cam, pincer, and
mixed femoroacetabular impingement (FAI), particularly among distinct populations, namely …

Background: The alpha angle is the most often used measure to classify cam morphology.
There is currently no agreement on which alpha angle threshold value to use. Purpose: To …

Background Both acetabular undercoverage (hip dysplasia) and overcoverage (pincer-type
femoroacetabular impingement) can result in hip osteoarthritis. In contrast to undercoverage …

Hip or groin pain in athletes is common and clinical presentation is often nonspecific.
Imaging is a very important diagnostic step in the work-up of athletes with hip pain. This …

Background Diagnostic ultrasound (US) is a commonly used imaging modality for
visualising tendon pathology and morphology. In comparison to magnetic resonance …

Background: Radiographic findings related to the cam and pincer variants of
femoroacetabular impingement (FAI) include measurements of the alpha angle and lateral …

Objectives To compare hip bony morphology between ballet dancers and a sporting control
group and to determine the relationship with hip pain. Methods Thirty-three professional …

Background The available evidence regarding normal ranges for the center-edge angle and
the alpha angle derives from a few small studies, and associated factors such as sex and …

Background: Increased attention has been directed toward the acetabular morphology in the
management of patients with femoroacetabular impingement syndrome (FAIS). Whether …

Objective Our objectives were to use 3D computed tomography (CT) to define head–neck
