The author expressed the original opinion: ligamentum capitis femoris (LCF) movements stimulate the production of synovial fluid. Additionally, John Barclay believed that the LCF restricts the translational movements of the femoral head upwards and outwards.

THE
ACETABULUM.
R, the acetabulum in which the head of the femur ; rolled, is better seen in the preceding Plate. It appears from the double lines that it is formed by the ilium, ischium, and pubis ; the ischium forming the greatest part, and the pubis the least. It is deeper above than below, as the femur is more liable to be luxated upwards than downwards. At the lower part, towards the foramen U, there is a deficiency of bone, at which part, the blood-vessels enter to supply the organs that were lodged within the cavity. In the recent subject, the whole is deepened by a ligamento-cartilagenous brim, which protects the thin osseous margin ; and which, extending across the notch, affords also protection to the blood-vessels that run under it. The whole of the bottom, excepting at T, the seat of an interarticular gland, is covered with cartilage. This gland assists the capsular ligament in supplying the joint with the necessary quantity of lubricating fluid : and from a ligament passing through it to the head of the femur, a ligament affected by every change of relative position between its opposite points of attachment, the excitement of the gland, and consequently its secretion, is in ordinary cases always proportioned to the quantity of motion. Yet the ligament, besides, performs another office in contributing to the security of the joint ; when the femur is impelled upwards and outwards, this ligament changes its direction ; and when the impulse is not too great, forces back the head into the acetabulum, producing the effect, not so much by its physical strength, as by a happy mechanical contrivance. This effect, as well as the contrivance by which it is produced, may be seen by removing the capsular ligament, by then dislodging the head of the femur, and afterwards pushing it upwards and outwards.
