Anteversion
Encyclopedia
Anteversion and retroversion are complementary anatomical terms of location
, describing the degree to which an anatomical structure is rotated forwards (towards the front of the body) or backwards (towards the back of the body) respectively, relative to some datum position.
More specifically, neck
anteversion is a neck tilted further forward than normal.
A woman's uterus
is typically tilted slightly forward or anteverted, but in certain cases it is tilted back and described as being a retroverted uterus
.
A misaligned pelvis
can be described as being tilted forward, or backwards. The degree of anteversion and retroversion varies between individuals.
The terms also describe the positioning of implants in arthroplasty
.
Anatomical terms of location
Standard anatomical terms of location are designations employed in science that deal with the anatomy of animals to avoid ambiguities that might otherwise arise. They are not language-specific, and thus require no translation...

Retroverted uterus
A retroverted uterus is a uterus that is tilted backwards instead of forwards. This is in contrast to the slightly "anteverted" uterus that most women have, which is tipped forward toward the bladder, with the anterior end slightly concave.Between 1 in 3 and 1-in-5 women has a retroverted...

Arthroplasty
Arthroplasty is an operative procedure of orthopedic surgery performed, in which the arthritic or dysfunctional joint surface is replaced with something better or by remodeling or realigning the joint by osteotomy or some other procedure.-Background:Previously, a popular form of arthroplasty was...
