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.^[1]

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.
