Fragments from the
book Marshall J. Anatomy for artists (1878). The author discusses the anatomy and briefly
the role of the ligamentum capitis femoris (LCF): «… checks adduction of the thigh, or a sinking down of the pelvis upon the
opposite side, and, possibly, also limits the reciprocal, horizontal rotatory movements
of the femur and the pelvis on each other».
Quote p. 65
The head of
the femur is almost entirely received into the acetabulum, a deep socket of the
hip-bone, thus forming the largest and most complete ball-and- socket joint in
the body. At a point on the inner side of the head of the femur, a little below
and also behind its centre, is a small rough, bifid , depression, for the
attachment of the ligamentum teres of the hip-joint. Opposite this point, the
head of the bone is, however, more prominent than elsewhere, and corresponds
with a non- articular depressed portion of the acetabulum.
Quote p. 68
The ligamentum
teres, which is attached by one end to the head of the femur, descends within
the hip-joint, to be attached to the margins of this notch ; continuous with
the notch, is a broad, shallow excavation, of a circular form, the fovea or pit
of the acetabulum, which extends into the floor of the socket, and lodges that
ligament, together with some fatty tissue and blood-vessels . Owing to the
presence of this pit or excavation, the floor of the acetabulum is
comparatively thin, and often translucent in the dried bone ; but it has no
weight to bear, and merely protects the ligamentum teres and other soft parts.
The articulating portion of the acetabulum is placed out-side or around the
circular fovea ; but, like the rim of the socket itself, it is interrupted,
opposite to the notch ; hence the articular portion of the acetabulum, which is
in contact with the head of the femur, does not form a complete cup, but
consists of a wide crescentic zone, or semilunar surface, smoothed for the
encrusting articular cartilage, and intervening between the slightly roughened
circular excavation and the rim of the socket ; its widest part is above, where
the greatest weight has to be borne; the narrower parts of the crescent extend
in front of and behind the notch, where little or no weight has to be
supported.

The head of
the femur is connected directly with the bottom of the socket, by the
ligamentum teres, or round ligament, fig. 88, which is unique, in the fact that
it passes across the interior of the joint. It is not cord-like in shape,
however, but triangular ; its narrower end is fixed to the double pit on the
inner aspect of the head of the femur ; becoming flattened, it passes down,
along a slight depression on the inner side of the head of the bone, fig . 90,
and is attached by its base, which is divided into two parts, to the ischial
and pubic margins of the notch of the acetabulum, blending with the ends of the
transverse ligament. It is completely invested by a tubular prolongation of the
synovial membrane. It is usually strong, but it differs much in thickness, in
different individuals.

Quote p. 223
Every
movement of the head of the femur in the acetabulum, is reciprocated by an
opposite movement of the innominate bone, and, therefore, of the entire pelvic
girdle, on the head of the thigh-bone. Thus, the backward movement of the
pelvis, performed in standing upright, is equivalent to extension, and the
forward movement in stooping, to flexion of the thigh ; the inclination of the
pelvis, outwards or inwards, corresponds to abduction or adduction, of the
thigh ; whilst the swinging of the pelvis horizontally forwards or backwards,
is equivalent to rotation of the thigh inwards or outwards. The ligamentum
teres checks adduction of the thigh, or a sinking down of the pelvis upon the
opposite side, and, possibly, also limits the reciprocal, horizontal rotatory movements
of the femur and the pelvis on each other.
