Comparison of MRI alpha angle measurement planes in femoroacetabular impingement.
Insufficient femoral head-neck offset is common in femoroacetabular impingement (FAI) and reflected by the alpha angle, a validated measurement for quantifying this anatomic deformity in patients with FAI. We compared the alpha angle determined on magnetic resonance imaging (MRI) oblique axial plane images with the maximal alpha angle value obtained using radial images. The MRIs of 41 subjects ...
متن کاملIs the frog lateral plain radiograph a reliable predictor of the alpha angle in femoroacetabular impingement?
The radiological evaluation of the anterolateral femoral head is an essential tool for the assessment of the cam type of femoroacetabular impingement. CT, MRI and frog lateral plain radiographs have all been suggested as imaging options for this type of lesion. The alpha angle is accepted as a reliable indicator of the cam type of impingement and may also be used as an assessment for the succes...

متن کاملFemoroacetabular Impingement
Hip and groin pain has, for many years, been a difficult diagnostic challenge. In the past decade there has been increased focus on femoroacetabular impingement (FAI) as a cause. FAI is now considered by many as a primary cause of hip joint degeneration. Our appreciation and understanding of FAI is currently increasing at an exponential rate. In this paper we review FAI as a pathology and revie...
متن کاملMRI for the preoperative evaluation of femoroacetabular impingement
Femoroacetabular impingement (FAI) refers to a condition characterized by impingement of the femoral head-neck junction against the acetabular rim, often due to underlying osseous and/or soft tissue morphological abnormalities. It is a common cause of hip pain and limited range of motion in young and middle-aged adults. Hip preservation surgery aims to correct the morphological variants seen in...
