we were going to include the deep lateral rotators in the
Anatomy Trains system, they would be, strangely, part
of this lower posterior track of the DFL (see also the
section on the 'Deep Back Line', p. 93). In fact, however,
even though there is a fascial connection between the
posterior adductors and the quadratus femoris and the
rest of the lateral rotators, the muscle fiber direction of
these muscles is nearly at right angles to the ones we
have been following straight up the thigh. Thus, this
connection cannot qualify as a myofascial meridian by
our self-imposed rules. These important muscles are
best seen as part of a series of muscular fans around the
hip joint, as they simply do not fit into the longitudinal
meridians we are describing here (see 'Fans of the Hip
Joint' 1 in Body\ published privately and available from
We will have an easier time finding a myofascial track
if we run inside the lower flange of the pelvis from the
adductor magnus and its septum up onto the medial
side of the IT-ischial ramus (Fig. 9.16). We can follow a
strong fascial connection over the bone onto the strong
outer covering of the obturator internus muscle, con-
necting with levator ani of the pelvic floor via the arcuate
line (Fig. 9.17). This is an important line of stabilization
from the trunk down the inner back of the leg.
The pelvic floor is a complex set of structures - a
muscular funnel, surrounded by fascial sheets and vis-
ceral ligaments - worthy of several books of its own. 2
For our purposes, it forms the bottom of the trunk
portion of the DFL, with multiple connections around
the abdominopelvic cavity. We have been following the
lower posterior track listed in Table 9.1. This track takes
us from the coccygeus and iliococcygeus portions of the
levator ani onto the coccyx, where we can continue
north with the fascia on the front of the sacrum. This

posterior 'head' of adductor magnus (Fig. 9.14).
From the ischium, there is a clear fascial continuity
up the inner layer of the buttock and the group of
muscles known as the deep lateral rotators (Fig. 9.15 and
