2025ChatGPT. Baroque

  2025ChatGPT, painting «Jacob Wrestling with the Angel in Baroque Style». Depiction of the circumstances and mechanism of the ligamentum capitis femoris (LCF) injury based on the description in the Book of Genesis: 25 And Ja cob was left alone; and there wrestled a man with him until the breaking of the day. 26 And when he saw that he could not pre vail against him, he struck against the hollow of his thigh ; and the hollow of Jacob's thigh was put out of joint, as he was wrestling with him. … 33 Therefore do the children of Israel not eat the sinew which shrank, which is upon the hollow of the thigh, unto this day; because he struck against the hollow of Jacob's thigh on the sinew that shrank.  ( 1922LeeserI , Genesis (Bereshit) 32:25-26,33) More about the plot in our work:  Ninth month, eleventh day   ( 2024 АрхиповСВ.

Localization of LCF Pathology

  Version : 20240418 Localization of LCF pathology is classified based on the anatomical-topographical principle. It is assumed that the LCF does not end near the attachment site but penetrates into it. LOCALIZATION OF LCF PATHOLOGY 1. Middle part 2. Distal end 3. Proximal end 4. Distal attachment area 5. Proximal attachment area 6. Medial surface 7. Lateral surface 8. Anterior edge 9. Posterior edge 10. Transsynovial 11. Subsynovial 12. Total Lesion The medial surface faces the bottom of the acetabulum. The lateral surface faces the femoral head. Transsynovial pathology implies changes including or only involving the synovial membrane. Subsynovial pathology is localized exclusively beneath the synovial membrane of LCF. Pathology can involve multiple parts of LCF, for example, damage to the distal end and proximal attachment area in a transacetabular fracture.   The distal part of LCF attaches directly to the bone of fovea capitis femoris.

1898AshhurstJ

    Report Ashhurst J. Tuberculosis of the hip joint (1898). The author discusses the function of the LCF as a supporting element of the body, its role in the development of deformity of the hip joint, reducing pressure and stress in the femoral head. The most notable quotes:  «Of course, the whole weight of the body is not sustained by this ligament, but mostly by the head of the femur in more or less close contact with the cotyloid cavity; but this ligament, I believe, serves to diminish the pressure of the pelvis upon the head of the bone, and to lessen strain. The position of the ligamentum teres is like that of the old-fasioned leather springs which used to be found in stage- coaches, the body of the coach being balanced upon two broad strong bands of leather. The pelvis is to a certain extent similarly balanced upon these ligaments on either side, which are attached to the heads of the thigh- bones, and then pass down to the lower edges of the cotyloid cavities. I b...

1750DrakeJ

  Fragment from the book Drake J. Anthropologia nova: or, a new system of anatomy. … The Third Edition Corrected. (1750). The author does not name the ligamentum capitis femoris (LCF), but accurately describes its appearance (short, thick, and round), and indicates the attachment points. Quote p. 432 CHAP. VIII. Of the Bones and Muscles of the Thigh, Leg and Foot … The first of these is the largest and most prominent, and has a large round Head, capp’d with a Cartilage, which is receiv’d into the Acetabulum or Socket, at the Ischium or Os Coxendicis; to which it is fastned by two Ligaments: One broad, thick, and membranous, surrounding the whole Edge of the Acetabulum, and Head of the Bone: The other short, thick, and round, springing from the bottom of the Acetabulum, by the side of the Mucilaginous Gland, (which is here the most considerable of the whole Body) and is inserted into the middle of the Cartilaginous Head. The Epiphysis, or Neck of the Bone on which this Head is seate...

  A fragment from the work by Bischoff TLW. Beiträge zur Anatomie des Gorilla (1879). The paper discusses the size of the ligamentum capitis femoris (LCF) of gorilla.   Quote p. 1 8. [Deu] 5. Muskeln der unteren Extremität. Ich erwähne zunächst, dass mein Gorilla an dem mehr als eine Halbkugel bildenden Schenkelkopf ein ansehnlich langes Ligam. teres besitzt. Translation [Eng] 5. Muscles of the lower limbs. First of all, I would like to point out that my gorilla has a rather long round ligament on the head of the femur, which forms more than one hemisphere.

1823GerdyPN

  The author mentions their observation of the displacement of the femoral head from the acetabulum outwards when the ligamentum capitis femoris (LCF) is stretched. Continuing experimental research, P.N. Gerdy discovered that the LCF, when stretched during adduction, also displaces the femur in the caudal direction (see 1833GerdyPN ). The translation from German was done in collaboration with ChatGPT 3.5.   Gerdy PN. Recherches, discussions, et propositions d'Anatomie, de Physiologie, de Pathologie, etc. Paris: Béchet, 1823. [fragment] Quote pp. 9 5 PROPOSITIONS La luxation du fémur en haut et en dehors est plus facile que celle en bas et en dedans, surtout parce que le ligament interarticulaire tend à s enrouler autour de la tête du femur, dans une violente adduction et qu il tire l os en dehors. Je m en suis assuré par l observation directe.   ASSUMPTIONS Dislocating the femur upwards and outwards is easier...

1851HyrtlJ

  The author expresses a classic view on the functions of the ligamentum capitis femoris (LCF): a conductor of blood vessels and a limiter of adduction of the femur. J. Hyrtl believed that it was impossible to completely dislocate the hip without tearing the LCF. Hyrtl J. Lehrbuch der Anatomie des Menschen, mit Rücksicht auf physiologische Begründung und praktische Anwendung. Wien: W. Braumüller, 1851. [fragment] Quote p. 265 In der Höhle des Gelenks liegt das runde Band des Schenkelkopfes (Lig. teres), welches an der Incisura acetabuli entspringt, und bei richtiger Neigung des Beckens, senkrecht zur Grube des Schenkelkopfes aufsteigt. Es beschränkt dieses Band die Zuziehung des Schenkels, und schreibt zugleich den durch die Incisura acetabuli eindringenden Blutgefässen den Weg vor, den sie zum Oberschenkelkopfe zu nehmen haben. Da das Band, wenn es in die Höhle des Gelenkes vorragen würde, durch Reibung viel zu leiden hätte, so...
