What is anteversion of the hip?
What is femoral anteversion? The femur is the long bone that connects the hip joint to the knee joint. Anteversion means “leaning forward.” Femoral anteversion is a condition in which the femoral neck leans forward with respect to the rest of the femur.
What is anteversion of the arm?
[an″te-ver´zhun] the tipping forward of an entire organ.
What is the difference between Retroversion and anteversion?
Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. The condition is usually congenital, meaning children are born with it.
What is anteversion and retroversion of the hip?
Because the lower part of the femur is connected to the knee, this also means that the knee is twisted outward relative to the hip. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. Femoral retroversion can occur in one or both legs.
How do you measure anteversion?
Femoral anteversion can be determined by measuring the angle formed between the long axis of the femoral neck and a line parallel to the dorsal aspect of the femoral condyles (posterior condylar axis, or PCA) on axial slices at MRI or CT.
What is the angle of anteversion?
Femoral neck anteversion (FNA) is the angle between the femoral neck and femoral shaft, indicating the degree of torsion of the femur. Differences in FNA affect the biomechanics of the hip, through alterations in factors such as moment arm lengths and joint loading.
What is combined anteversion?
Combined anteversion in the hip means the sum of the anteversion of the acetabulum and the femur. In total hip arthroplasty (THA) it means the sum of the cup and stem anteversion.
How do you assess femoral anteversion?
There are various ways via which femoral anteversion can be measured. These are some methods used: imaging using radiography, fluoroscopy, computed tomography (CT), ultrasound (US), and magnetic resonance imaging (MRI) as well as functional assessments.
What is femoral offset?
Femoral offset: general remarks and definitions. Femoral offset is the distance from the center of rotation of the femoral head to a line bisecting the long axis of the femur (Fig. 1). This radiographic measurement should be accurately performed and varies according to the hip rotation.
What is an Anteflexed uterus?
Anteflexed is another positioning the uterus may favor. This means that the anterior tilt of the cervix is severe, resulting in a much greater forward flexing uterus in the abdominal region. A woman with an anteflexed uterus may experience an increase in pressure in the pelvic region.
What is acetabular Retroversion?
Acetabular retroversion (AR) consists of a malorientation of the acetabulum in the sagittal plane. AR is associated with changes in load transmission across the hip, being a risk factor for early osteoarthrosis. The pathophysiological basis of AR is an anterior acetabular hyper-coverage and an overall pelvic rotation.
What Is hip lateralization?
Lateralization of the hip center of rotation is measured relative to the radiographic “U-landmark”, or relative to the pelvis median axis if radiographically possible. The height of the hip center is measured relative to the bi-ischiatic line or to the bottom of the radiographic “U-landmark”.
What does anteversion mean in medical terms?
Medical definition of anteversion: a condition of being anteverted —used especially of the uterus.
What is femoral anteversion of the hip?
What is femoral anteversion? The femur is the long bone that connects the hip joint to the knee joint. Anteversion means “leaning forward.”. Femoral anteversion is a condition in which the femoral neck leans forward with respect to the rest of the femur.
What is the difference between retroversion and anteversion?
Anteversion and retroversion are complementary anatomical terms of location, describing the degree to which an anatomical structure is rotated forwards or backwards respectively, relative to some datum position. More specifically, neck anteversion is a neck tilted further forward than normal.
What is the meaning of Ante Versio?
[ante- + Mediev. L. versio, a turning] Forward displacement, torsion, or turning forward of a body segment. [ ante – + Mediev. L. versio, a turning] Forward displacement or turning forward of a body segment. [ ante – + Mediev.
