Antavarsan. The acetabular anteversion varies greatly, which leads to increased hip prosthesis wear and even hip dislocation. The lateral X-ray of the spine and pelvis is recommended in supine, standing, and sitting positions before THA.

Acetabular implant anteversion angles of each group were 22.4° ± 12.3°, 24.9° ± 11.1°, and 26.2° ± 10.8°, respectively (Fig. 2). Acetabular implant anteversion in the group with less than 15° native acetabular anteversion was significantly smaller than in the other two groups.

Furthermore, there is a temptation to use “anteversion” as measured utilizing a cross-table lateral radiograph and “anteversion” as measured on an axial CT interchangeably, while these numbers in fact differ, and the discrepancy between these two methods is not independent of the inclination of the cup .Hence anteversion measured by different methods cannot have similar values, but a good correlation between methods is an indicator of validity of the measurements. There is no gold standard for the calculation of acetabular anteversion, but measurements on CT scans can be considered to be more accurate than radiographic …Femoral anteversion at each level was calculated. Average anterior (lesser trochanter) and posterior cortex anteversions (femoral neck) were calculated based on the sagittal 3-point fixation. Results: From the lesser trochanter to head-neck junction, femoral anteversion decreased gradually from more to less than stem anteversion. For hips with ...Glenohumeral arthritis, or Shoulder Arthritis, is a degenerative joint disease of the shoulder characterized by damage to the articular surfaces of the humeral head and/or glenoid.

Excessive anteversion or retroversion can lead to dislocation. Prosthesis fixation. Femoral stem fixation can be either cemented or non-cemented (biological) fixation. There is a tendency to use non-cemented femoral stems in younger patients, due to higher reported rates of loosening of cemented stems in long term follow-up.[Methods] The maximum pelvic anteversion and retroversion angles were measured manually five times by a goniometer in a sitting position that allowed free movement of the knee joints. [Results] There was a significant effect of age group on the maximum pelvic anteversion and retroversion angles and pelvic range of motion (the difference between ...The acetabular anteversion angle (AAA), internal wall anteversion angle (IWAA), anterior wall height of the acetabulum (A), acetabular posterior wall height (P), and acetabular width (W) were ...Patellofemoral pain syndrome (PFPS) is one of the most prevalent musculoskeletal injuries comprising 25 % of knee injuries seen in sports medicine clinics [1, 2].PFPS is the most common knee condition in runners and adolescents [3, 4].Women are two times more likely to develop PFPS than men [].The pathophysiology of PFPS is not …The angle of anteversion (AA) is an important index to assess the torsion of the femur. Femoral torsion may be inward (increased femoral anteversion) or outward (retroversion). Different methods have been reported for measurements of AA, and the radiographic method is the easiest method.Combined anteversion in the hip means the sum of the anteversion of the acetabulum and the femur.

The three most common causes of intoeing (i.e., metatarsus adductus, internal tibial torsion, and increased femoral anteversion)...Femoral anteversion is a condition in which the femoral neck leans forward with respect to the rest of the femur. This causes the leg to rotate internally, so that the knee and foot twist toward the midline of the body. Some degree of rotation of the femur is always present as kids grow.

anteversion and retroversion movements has not been described. The upper portion of the gluteus maximus, for example, can stabilize the pelvis in the frontal plane, whileThus, cup inclination and anteversion depend on pelvic tilt, which itself depends on the posture of the patient.

Treatment typically involves periacetabular osteotomies for those with concentrically reduced hips with congruous joint space ...Introduction. Anteversion of the acetabular component is an important factor for long-term results of total hip arthroplasty (THA). It is generally accepted that the acetabular component should be placed with an anteversion of 15°±10°, and inaccurate placement can cause impingement, dislocation and accelerated wear (1-5).Computed …Increasing anteversion in this case would theoretically reduce the chance of posterior dislocation based on the mechanics of the hip joint (Mihalko and Whiteside 2004, Biedermann et al. 2005).
