The toe-out attitude of the foot is a consequence of pathology at the proximal segments of the body, that is persistent tibia torsion and femoral anteversion
. Therefore, our treatment strategies must target the cause, but not the effect of the problem.
Long life span, small abnormally shaped bones (femur and acetabulum), thinner femoral cortices and smaller femoral canals, excessive femoral and acetabular anteversion
, growth and re-modeling of bone, and osteoporosis from steroids and soft tissue contractures present the surgeon with a very complex challenge, requiring detailed preoperative planning.
Pelvic tilt is a measurement of functional anteversion
, and inclination of the pelvis can be affected by lumbosacral and hip pathologies such as scoliosis, femoroacetabular impingement, and acetabular or femoral dysplasia, among others.
El tallo del vastago de ensayo se inserto teniendo cuidado de la anteversion
, que fue juzgada por el eje largo de la pierna para alcanzar la misma longitud del miembro, que tambien fue comprobada por la prueba de Shuck con el desplazamiento de no mas de 2 - 3 mm.
To measure the distance between tip of greater trochanter and centre of femoral head (in the line of femoral anteversion
the greatest distance was taken), intra operatively.
Femoral version, neck-shaft angle, and acetabular anteversion
in Chinese han population: A retrospective analysis of 466 healthy adults.
PINNACLE Sector Acetabular Cup (DePuy Synthes, Joint Reconstruction companies of Johnson and Johnson, Leeds, UK) was inserted in 40-45 degrees of inclination and 20 degrees of anteversion
. Confirmation of adequate fit was done by visual inspection through the hole in the acetabular cup to confirm that cup is well seated with the acetabular bone.
This represents posterior overcoverage or relative anteversion
of the acetabulum.
For instance, there is associated adaptive shortening of the soft tissues, capsular constriction, increased femoral anteversion
, acetabular dysplasia, presence of obstructing structures such as the fibrofatty tissue in the acetabulum, hypertrophied ligamentum teres, the transverse acetabular ligament and fixed inversion of limbus.1-4,13,14 Femoral diaphyseal shortening is superior to traction as an aid in operative reduction of DDH in older children.
Subjects were randomly instructed to urinate in five different test situations: anteversion
with straining, retroversion, retroversion with straining, and forward bending without straining.
was determined in accordance with preoperative femoral anteversion
Among the different spinopelvic parameters that were studied in this paper, there was only a postoperative increase of SS that represented an essential compensatory mechanism to resist the reduction of the anteversion
of the pelvis, even in preoperatively balanced spines .
