WebMost patients with FAI have a cam deformity, characterized by a reduction of offset or abnormal asphericity at the anterolateral femoral head-neck junction (Beck et al. 2005). This may be recognized by radiography (Clohisy et al. 2008 ), CT (Beaule et al. 2005 ), and MRI (Notzli et al. 2002 ), and quantified by measuring the alpha angle (Notzli et al. 2002 ) … Web20 nov. 2008 · We (CA, MD) measured the shape of the femoral head-neck junction using the radial slices of the MRA in 14 cuts around the femoral head-neck. At each position, the angle alpha was measured analogous to the technique described previously (Fig. 3) [].We measured the height of the asphericity at an angle alpha of 43° to obtain an idea of the …

WebTo determine the strength of common radiographic and radial CT views for measuring true femoral head asphericity. Patients and methods. In 15 patients with cam femoroacetabular impingement (FAI) and 15 controls, alpha angles were measured by two observers using radial CT (0°, 30°, 60°, 90°) and digitally reconstructed radiographs (DRRs) for ... Web10 jan. 2024 · At birth, the ossific pattern of the femoral neck is a meshwork of uniformly distributed fine trabeculae. The adult pattern develops slowly; in one half of children between 12 and 18 months, the principal medial and lateral arching pattern is faintly evident [].These linear condensations are well developed by age 5; trabeculae aligned with the medial … WebIf the femoral head-neck junction is identified to be the cause of FAI, contouring of the femoral head and neck by excision osteoplasty is done.
