Selected fragments of the treatise describe the topography, function, geometric and physical properties of the ligamentum capitis femoris (LCF). What is especially noteworthy is that the author describes one of the symptoms of LCF damage, lameness, and explains its cause. We find the first ever mention of this symptom in non-scientific literature in Chapter XXXII of the book Genesis (1922LeeserI, 32:32).

Quote p. 81

Nam praeter eam cartilaginem, quae crustae ritu circundatur tam femoris capiti, quam acetabulo: exurgit ex labris ipsius sinus crassa quaedam, & circularis cartilago, quae acetabuli capacitatem auget; atque ita complectitur altum femoris caput, vt ne de sua sede egredi, luxariue tam facile possit. atque vt huiusmodi capitis insercio firmius in eodem acetabulo resideat; e medio eius incrustatae appendicis teres, ac validum ligamentum nascitur, quod in medio sinu figitur; sicq; articulationem hanc alioqui laxam maximopere colligat, continetq;.


For in addition to the cartilage [of the joint capsule], which surrounds the head of the femur and the acetabulum, there is, at the very edge of this socket, a thick circular cartilage, increasing the capacity of the acetabulum; in this way, it clasps the large head of the femur so that it cannot easily come out of its seat or be dislocated. And in order for the head of the bone to be more firmly held in the acetabulum, from the middle of the protruding cartilage of the head originates an encrusted rounded appendage, giving rise to a strong ligament, which is fixed in the center of the socket; thus it greatly strengthens and supports this otherwise rather loose joint. 

Quote p. 84

Iccirco natura non modo altiorem insertionem effinxit, & cum profundo acetabulo cartilaginem composuit; vt ipsum adauctum, altiusq; redditum femoris caput facilius susciperet; Verumetiam teretem, ac robustam copulam parauit, quam e sinu quodam non leui in medio pene capitis vertice, magis tamen versus interiora produxit: atque id in acetabuli fundum immittendum curauit vinculi, ac firmamenti validioris gratia. 

Therefore, nature not only created a deeper attachment, but also added cartilage for the deep acetabulum; so that it would increase and deepen to better hold the femoral head; it also prepared a pair for it, a rounded and sturdy ligament, which arises from a somewhat not smooth depression in the middle of the head, but rather closer to its inner part, and took care to connect it to the bottom of the acetabulum, which ensures a stronger connection.

Quote p. 108

In articulo femoris cum osse coxendicis ilei, ac pubis, praeter membraneum quidem vinculum, sed crassum, quod articulis omnibus commune est, ligamentum videbis teres ac longiusculum, quod cum a profundo acetabulo ortum ducat, in superius femoris caput insertum deperditur, idq; roboris ergo; quod dum haec pars laxatur saepenumero disrumpitur: & quamuis os in locum pristinu redeat, luxatus tamen semper claudicat: hoc enim ligamentum impedimento est quominus ossa illa cohaereant.

In the hip joint, at the point of its connection with the pelvic bones: the ilium and the pubis, in addition to the membranous ligament common to all joints, you will see a rounded and elongated ligament, which starts from the depths of the acetabulum and which connects to the upper part of the head of the femur; this formation is designed to strengthen the joint. However, when it relaxes, it often tears. And even if the bone returns to its place, lameness always remains after a dislocation: this is explained by the fact that the ligament interferes with the bones rejoining.

Vertebrates

VERTEBRATES According to the molecular clock, a specific method for dating phylogenetic events, vertebrates (Vertebrata) separated from arthropods (Arthropoda) 976±97 Ma (2004HedgesSB_ShoeJL). The latter began to dominate in species diversity with the Cambrian burst of radiation, which occurred 520 Ma (2010EdgecombeGD). This ratio in the fauna of the Earth is still preserved. Approximately 525 Ma, the phylum Chordates separated from the group of bilaterally symmetrical animals (1995ChenJY_ZhouGQ). In turn, the evolution of chordate organisms led to the formation of the first vertebrates at least 500 Ma, from which the jawed mouths 450-400 Ma descended, becoming the ancestors of the placoderms or "armored" fish (Placodermi) (1979 НаумовНП _ КарташевНН ).

Postulates of LCF Mechanics

  Postulates of LCF mechanics   We continue to develop a new scientific direction « Mechanics of the Ligamentum Capitis Femoris »: https://roundligament.blogspot.com/2024/10/lcf-mechanics.html Analysis of the accumulated information allowed us to clarify the postulates of this scientific discipline: - Strong, flexible, and non-stretchable with specific attachment points. - Limits adduction, rotation, and cranial displacement of the femur. - Ensures rhythmicity, symmetry, and energy efficiency of walking. - Performs the function to suspend the pelvis during single-leg support. - Shunts load on the femoral head and the abductor muscle group of the hip joint. NB! Considering these positions in your clinical practice, you will reduce the likelihood of developing hip osteoarthritis and gait disturbances in patients.

Australopithecus Gait

  In our opinion, the ligamentum teres or ligamentum capitis femoris (LCF) in Australopithecus afarensis determined the gait. Its pelvis moved in the frontal plane similar to that of a modern human. In the horizontal plane, the rotational movements of the Australopithecus pelvis were carried out with a significantly smaller amplitude. Presumably Australopithecus afarensis had relatively shorter steps than Homo sapiens. During walking, the shoulder girdle was positioned in the frontal plane, and the arms exhibited minimal oscillation in the sagittal plane. Illustration: Comparative analysis of LCF movements On the right is the acetabulum of Homo sapiens (photo by the author); on the left is the acetabulum of Australopithecus afarensis 3D model of the pelvis (fragment of a screenshot from  sketchfab.com ); The distal end of the LCF (ligamentum teres) in Australopithecus moved in the horizontal plane in the acetabulum fossa with a smaller amplitude than in modern humans. k eyword...
