  T he ligament of the head of femur or ligamentum capitis femoris (LCF) is the key to a graceful gait and understanding the causes of hip joint diseases. We present promising scientific knowledge necessary for preserving health,  to create new implants and techniques  of treating degenerative  pathology and damage of the hip joint. Project objective : preserving a normal gait and quality of life, helping to study of hip joint biomechanics, developing effective treatments for its diseases and injuries. In translating to English, the author is assisted by ChatGPT (version 3.5)  and the Google Translate service .  We're sorry for any flaws in the syntax.

1851CooperAP

  Fragments of the book Cooper AP. A Treatise on Dislocations and Fractures of the Joints (1851) dedicated to ligamentum capitis femoris (LCF). The author discusses changes in the LCF during hip fractures, dislocations and role of its blood vessels in supplying the femoral head.   Quote pp. 51-52 ON DISLOCATIONS IN GENERAL. … Mr. Howden, who was one of our most intelligent apprentices at Guy's Hospital, and was afterwards surgeon in the army, related the following case: - A man had his thigh dislocated upwards and backwards on the ilium, which was soon after reduced; the next day a considerable swelling was observed on the part, which continued to increase, accompanied with rigors, and in four days the patient died. On dissection, the capsular ligaments, and ligamentum teres, were found entirely torn away, and a considerable quantity of pus extravasated in the surrounding parts." * (See Minutes of the Physical Society, Guy's Hospital, Nov. 12th, 1791.)

1495Johannes de Ketham

  Fragment from the book Johannes de Ketham. Fasciculus medicine (1495). An excerpt from the treatise by Mondino de Luzzi describing the anatomy and role of ligamentum capitis femoris (LCF) damage in the genesis of hip diseases. The pathogenesis of lameness and soft tissue atrophy of the leg in LCF pathology is discussed. The cited author uses and explains a rare synonym for LCF – « vertebrum ». The original in Latin in our adaptation. The treatise by Mondino de Luzzi was also published in other works: 1541MondinoL_DryanderJ , 1550CortiM .  See our commentary at the link:   1495Johannes de Ketham [Rus]. Quote.

1833GerdyPN

  P.N. Gerdy, in his experiment, discovered tensioning of the ligamentum capitis femoris (LCF) during thigh adduction. At the same time, it was noted for the first time that the consequence of LCF tension during hip adduction is a downward and lateral displacement of the femoral head. Normally, this mechanism provides unloading of the upper articular surfaces when supporting one leg (see 1874SavoryWS ). The translation from French was done in collaboration with ChatGPT 3.5.   Gerdy PN. Physiologie médicale, didactique et critique. T. 1. Paris: Librairie de Crochard, 1833. [fragment] Quote pp. 551-554   L'inclinaison de la cuisse en dehors, que l'on nomme son abduction, est un mouvement assez étendu, mais qui pourtant ne permet pas à la cuisse de se placer perpendiculairement à sa direction verticale. Les batteleurs peuvent se reposer sur un plan horizontal, les cuisses écartées en sens opposé. Dans l'inclinaison ...

1615BauhinC

  Fragments from the book Bauhin C. Institutiones anatomicae (1615). The author writes about the attachment, properties and role, and probably also about the elongation of the ligamentum capitis femoris (LCF). The consistency is remarkably described as «quasi cartilagineo» (almost cartilaginous). Galen of Pergamon wrote about these properties of LCF  ( 2020ArkhipovSV_ProlyginaIV ). Quote p. 78. OSSA INFIMI VENTRIS. … Adl atera ossa duo sunt, quorum partes superiores & latiores, ossa Ilium: inferiores & exteriores, ossa Coxendicis (quibus prægrande acetabulum inest, cum femoris capite, nexu validifsimo copulatum) quæ antrorsum tenuia, perforata, & in Pube (vnde ossa Pubis dicuntur) cartilagine media nectuntur. Hæc diuersis nominibus donata, quia ad septimum vsq; annum, vtrinq; ex trib. ossibus, cartilaginibus iunctis, constant. Quote p. 356. OSSA ET LIGAMENTA PEDIS. At femur, coxendici ligamento duplici nectitur: altero communi membraneo, orbiculatim articulum ambie...
