Fragments from the book Bell J. The anatomy of the human body. Vol. 1. (1808). The author describes the anatomy of the ligamentum capitis femoris (LCF) and its synovial membrane.

2. The head
of the thigh-bone is likewise the most perfect of any in the human body; for
its circumference is a very regular circle, of which the head contains nearly
two-thirds : It is small, neat, and completely received into its socket, which
is not only deep in it self, and very secure, but is further deepened by the
cartilage which borders it; so that this is naturally, and without the help of
ligaments, the strongest joint in all the body ; but among other securities
which are superadded, is the round ligament, the mark of which is easily feen,
being a broad dimple in the centre of its head.
Quote pp. 440-442
In addition
to this general capsule, there are two internal ligaments, 1st, The round
ligament, as it is called, which comes from the centre of the socket to be fixed
into the centre of the ball of the thigh-bone. It is not round, but flat or
triangular. It has a broad triangular basis, rooted in the socket exactly at
that place where the several bones of the socket meet, forming a triangular
ridge, which gives this triangular form to the central ligament. It has three
angles, and three flat fides. It is broad where it arises from the bottom of
the socket, is about an inch and a half in length, grows narrower as it goes
outwards towards the head of the bone, and is almost round where it is
implanted into the dimple in the head of the thigh-bone; at which point it is so
fixed as to leave a very remarkable roughness in the naked bone. But round the
roots of this ligament, and in the bottom of the socket, there is left a pretty
deep hollow, which is said to be filled up with the synovial gland. It is
wonderful how easily authors talk of the synovial gland, as if they had feen it;
they describe very formally its affections and diseases, as when hurt by a blow
upon the trochanter; yet there is no distend gland to be found. There is a
fringed and ragged mass lodged in the bottom of the socket, hanging out into
the hollow, and continually rubbed by the ball of the thigh-bone in its
motions: the fringes and points certainly are duds from which v/e can squeeze
out mucus ; but it is by no means proved that they belong to a synovial gland;
and it looks rather as if the duds were themselves the secreting organ, like
the lacunas or mucous bags in the tongue, or in the urethra vagina, esophagus,
and other hollow tubes. Such a structure is fitter for suffering the strong pressure
and continual adion of the thigh-bone than any determined gland. We see then
nothing but mucous ducts of a fringed form, hanging down from this hollow into
the cavity of the joint; a quantity of fat accompanying the se fringes; and a
pappy mucous membrane, which keeps these fringes and fatty membranes orderly
and in their places, and which ties them so to the angles of the triangular
ligament, that they must move with the motions of the joint. This mucous
membrane, which keeps these fatty fringes orderly, has two or three small bridles
in different directions; whence they are named the ligamenta mucosa, or
ligamentula massae adiposae glandulosa; and this may be considered as the continued
inflection of the softer internal lamella of the capsule, which not only lines
the socket, but is reflected over the central ligament, and over the globe of
the thigh-bone, covering them also with a delicate mucous coat. Other fringes
of the fame kind are found at the lower part of the joint, lying round the neck
of the thigh-bone, near the angle where the capsular ligament is implanted into
the root of the great trochanter: the liquor from these mucous fimbriae, with
the general serous exudations, are mixed and blended for lubricating the joint.
