Fragments from the book: Ecker A. The anatomy of the frog (1889). The author points out the presence of the ligamentum capitis femoris (LCF) in the frog and the presence of a similar structure in the shoulder joint. The text in Russian is available at the following link: 1889EckerA.

The shoulder-joint. The socket is formed by the posterior border of the scapula, by both the processes of that bone, the outer portion of the coracoid, and besides these by cartilage, which forms the articular surface already described (Fig. 33). In the macerated bone the floor of the socket opens dorsally into a fossa between the processes of the scapula (Fig. 32). This opening, in the natural condition, is closed by synovial membrane only; the cartilage covering the rest of the space being absent (the sac may easily be inflated, either from the joint itself or through the opening). The margin of the socket consists of a labrum, partly fibrous and partly cartilaginous, which is easily removed entire. The capsule, which is attached beneath the caput humeri, arises from this. From the articular cartilage of the ventral margin of the socket, and from the adjacent part of the scapula, proceeds a strong band, which is inserted into the flattened outer surface of the head.

Quote p. 49.

The femur, os femoris (Fig. 44). The shaft is cylindrical, with a slight double or S-shaped curve. In the anterior portion the convexity is directed upwards, in the two hinder thirds downwards. Towards the hinder extremity it is flattened from above downwards. The anterior extremity is a rounded articular head placed directly on the shaft like that of the humerus. This head is somewhat flattened from side to side ; and in structure resembles that of the humerus. The inferior extremity is rounded below, but flattened above (towards the hollow of the knee) and behind.

Hip-joint. The articular cavity is deepened by a fibrous ring, labrum cartilagineum, which fits closely upon the caput femoris ; from this labrum the joint-capsule arises, to be inserted behind the head ; close to the lower border of the cavity a Ligamentum teres arises, which is inserted into the caput femoris.

Test catalog of the LCF pathology

Test catalog of the ligamentum capitis femoris pathology By Sergey V. Arkhipov, MD, PhD CONTENT [i] Abstract [ii] Introduction [iii] Testing in the supine position [iv] Testing in a standing position [v] Gait study [vi] References [vii] Application [i] Abstract A description of tests for the detection and differential diagnosis of ligamentum capitis femoris (LCF) pathology is presented. [ii] Introduction One of the first studies devoted to the diagnosis of LCF injury demonstrated a variety of symptoms: groin pain, hip stiffness, sometimes long-standing minimal clinical findings, or signs similar to osteoarthritis (1997GrayA_VillarRN). More than a decade later, researchers concluded: "Unfortunately, there is no specific test for detecting LCF tears." The signs known at that time were nonspecific and were also observed in other intra-articular pathologies of the hip joint (2010CerezalL_Pérez-CarroL). The a...

Who, When, and Where Wrote the Book of Genesis?

Who, When, and Where Wrote the Book of Genesis? A Medical Hypothesis By Sergey V. Arkhipov, MD, PhD & Lyudmila N. Arkhipova, BSN CONTENT [i] Abstract [ii] Introduction [iii] Egyptian physician [iv] Asian diviner [v] Conclusion [vi] References [vii] Application [i] Abstract The Book of Genesis is an example of an ancient literary text that contains important medical insights. We propose that it was written in northern Egypt in the late 17th century BCE, approximately ten years after the Minoan eruption. The protograph likely emerged from the collaboration between an Asiatic seer, who rose to the rank of an Egyptian official, and an Egyptian physician-encyclopedist. By refining its dating and authorship, this hypothesis positions Genesis as a credible source of medical and historical data, thereby enhancing its value for interdisciplinary research.

«Prof. Partridge in his lectures on anatomy at King's College was accustomed to compare the Ligamentum Teres, in its function, to the leathern straps by which the body of a carriage is suspended on springs » ( 1874SavoryWS ). Perhaps Nikolai Pirogov listened to these lectures ( 1859PirogoffN ). The analogy that Richard Partridge used could have arisen after reading the monograph Bell J. The Principles of Surgery (1801) . In it, the author depicted a cart and a pelvis resting on the head of one and two femurs. However, there is no mention of ligamentum capitis femoris (LCF) in the chart descriptions.

Key Role of the LCF

In the experiments conducted on the pelvis-femur-muscle-ligaments model, we found that when the contralateral pelvic drop occurs, the ligament of the head of femur become maximally tense; simultaneously, there is relaxation and lengthening of the gluteus medius muscle; the pelvis spontaneously rotates towards the stance limb (forward), and the load on the hip joint decreases. Thanks to the functioning of the ligament of the head of femur the walking is smooth, rhythmic, and energy-efficient.

Congenital Hip Dislocation. Pathogenesis

An original view on the pathogenesis of congenital hip dysplasia, congenital dislocation and subluxation of the hip. One example of the importance of ligamentum capitis femoris (LCF) and the influence of a mechanical factor on living systems is a group of diseases of the hip joint such as congenital hip dysplasia, congenital subluxation and congenital hip dislocation. The last of these pathological conditions is an extreme degree of severity of the previous two. Common to these pathological conditions is the presence of connective tissue dysplasia syndrome of varying severity. It is based on a decrease in the strength and elasticity of connective tissue structures. The consequence of this is that a standard load, for example, on ligaments causes their plastic deformation: thinning, elongation, and in some cases, rupture. This occurs due to both mechanical and biological processes (for more details, see the Law of Bioinduction ). If, in connective tissue dysplasia syndr...
