The anterior pelvic plane tilt (APPt) is defined as the angle between the plane created by the bilateral anterior superior iliac spine to the pubic symphysis (A) and the coronal...

Anatomical pelvic tilt is defined as the angle between the anterior pelvic plane (APP) and the line connecting the midpoint of the S1 endplate and the center of the femoral head.

Anterior pelvic plane angle (APPA) measurement using two-dimensional lateral images of EOS imaging. APPA is the angle between the line connecting the midpoint of both anterior superior iliac spines (ASIS) and the pubic symphysis.

2019年10月17日 · A higher degree of tilt of the anterior pelvic plane angle (APPA) has been reported in patients with DDH than in normal subjects [2, 3], and it has been considered to increase bony coverage of the femoral head .

In 1990, Anda et al. 9 proposed the concept of the anterior pelvic plane (APP), which was defined as the plane formed by the bilateral anterior superior iliac spines and the upper margin of pubic symphysis. The angle between the APP and the vertical line is used to evaluate the degree of the pelvic tilt and is known as the APP angle.

Anterior Pelvic Plane (APP) is defined as the plane through the right and left anterior superior iliac spines (R- ASIS and L-ASIS) and the Symphysis Pubis (SP) (Fig. 1b). Traditionally,...

2023年4月5日 · This study aimed to quantitatively evaluate lateral center-edge angle (LCEA) and anterior center-edge angle (ACEA) according to sex and the anterior pelvic plane (APP) tilt angle and analyze the correlation between these measurements and acetabular coverage.

2019年10月17日 · The tilt of the pelvis may be more dependent on anatomical-PT, a morphological parameter of the pelvis, than the lateral CE angle, anterior CE angle, posterior CE angle, and acetabular anteversion on bony coverage of the acetabulum. This study is the first to investigate the correlation between func …

2019年5月31日 · Radiographic parameters included sagittal anterior pelvic plane (APP), sagittal vertical axis (SVA), sacral slope (SS), pelvic inclination (PI), and lumbar lordosis angle (LL). The APP was defined as the angle between the anterior pelvic plane and the vertical plane. A positive value indicates pelvic retroversion.

The pelvic incidence (PI), anatomical pelvic tilt (aPT), and anatomical sacral slope (aSS) were measured on the pelvic synthesized 2D lateral radiography imagines. Because the angle between APP and vertical line was about 4°, Angle1 and tPT were calculated using the following formulas: Angle1 = aC7SA - 4; PT = aPT + 4.
