The APP is defined as the plane created by the bilateral anterior superior iliac spines and the pubic symphysis (Fig.
However, the variability noted in these meta-analyses suggests that there may be an even better strategy: since the 2nd sacral tubercle is very dependably situated between the posterior superior iliac spines (7,20,44), numerating lumbar levels based on this landmark association might be most accurate.
003 ASIS = anterior superior iliac spine, GT = greater trochanter, PSIS = posterior superior iliac spine.
When neutrally positioned, the pelvis's anterior superior iliac spine (ASIS) and pubis will be in one vertical plane (Figures 2 and 7).
5) Avulsion fractures of the anterior inferior iliac spine occur due to a straight pull of the head of the rectus femoris muscle, (3,6) and generally occur when there is hyperextension of the hip joint and the flexion of the knee, as in the action of kicking a ball.
The point of termination of the abdominal aorta corresponds to the level of the fourth lumbar vertebra; a line drawn from it to a point midway between the anterior superior iliac spine and the symphysis pubis indicates the common and external iliac arteries.
He reported that the palpation point of maximum sensitivity is determined by pressure being applied with a finger (McBurney's sign), and that this point is located between one and one-half to two inches from the right anterior superior iliac spine (McBurney point) on a straight line drawn from the spinous pro cess to the navel (3, 4).
Four points, on the right and left anterior-superior iliac spine (ASIS) and posterior-superior iliac spine (PSIS), were used to define the pelvic frame, with the medial-lateral axis being the line connecting the right and left ASISs, and the superior-inferior axis being that normal to the surface defined by the 2 ASISs and the midpoint of the PSISs.
Thoracic fibres of longissimus and iliocostalis lumborum arise from thoracic spine (Macintosh and Bogduk 1987) and span the entire lumbar spine forming the erector spinae aponeurosis which moves freely over the lumbar erector spinae (Macintosh and Bogduk 1994), connecting to the sacrum and posterior superior iliac spine (Macintosh and Bogduk 1987).
