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...

1730CheseldenW

Fragments from the book Cheselden W. The Anatomy of the Human Body (1730). The author draws attention to the role of ligamentum capitis femoris (LCF) in counteracting hip dislocation and maintaining the femoral head in the joint. The work notes that the LCF is “powerful” and “short” - “about two inches” i.e. approximately 5 cm! This error will be corrected in a subsequent treatise ( 1733CheseldenW ) . Quote pp. 43 - 44 Chap. VII. Of the Ligaments At the upper part of the articulation of the Os Femoris and Os Innominatum, is a strong ligament of great consequence; it contributing very much to preserve that joint from being luxated by the weight of the body. And from the lower edge of the Acetabulum of the Os Innominatum, runs a ligament to the middle of the head of the Os Femoris, about two inches long (which the Motion in this joint requires) called Teres, or Rotundum, whose use is to prevent the Os Femoris from being luxated upwards, but down wards it will le...

Ligamentum capitis femoris: first written mentions S.V. Arkhipov, D.V. Skvortsov SUMMARY Background. A ligamentum capitis femoris (syn. ligamentum teres) is one of the least studied anatomical structures. We know little about its role in the musculoskeletal system, and even less about its first written mentions. Purpose. This article is intended to clarify who and when first described the connection of the head of the femur in the medical literature, and to provide a hypothesis about its first mention in the history of mankind. Material and methods. We reviewed the oldest written sources available to us, covering the anatomy of the hip joint and ligamentum capitis femoris. Conclusion. The first description of the ligamentum capitis femoris in the medical text is given by Hippocrates of Kos in the treatise Instruments of Reductions (V-IV century BC). According to our hypothesis, the first in the history of mankind to mention a ligamentum capitis femoris, is cont...

Human Children. Retelling of Chapter 1

Short retelling of chapter 1 of the essay: Arkhipov S.V. Human Children: The Origins of Biblical Legends from a Physician's Perspective. Joensuu: Author's Edition, 2025. [In Russian] Chapter 1. THE BEGINNING OF THE WORLD The Bible stands as a remarkable testament to religious and philosophical thought, passed down through the ages with minimal alterations. At its core lies a collection of texts rooted in the sacred writings of Jewish and Samaritan traditions, known as the Torah, meaning "Law" or "Teaching." In its narrowest sense, the Torah comprises the first five books of the Hebrew Bible, collectively called the Tanakh—an acronym derived from the Hebrew terms for "Law/Teaching" (Torah), "Prophets" (Nevi’im), and "Writings" (Ketuvim). Beyond this Written Torah, there exists an Oral Torah, which includes the Mishnah, Talmud, and Midrash, offering interpretations and expansions of the written texts. The Written Torah it...

1877MorrisH

An excerpt from the article by Morris H. Dislocations of the Thigh: their mode of occurrence as indicated by experiments, and the Anatomy of the Hip-joint (1877, pp. 161-170). The author noted that the ligamentum capitis femoris (LCF) is stretched during flexion, adduction, and external rotation. It was found that the LCF is always damaged in hip dislocations, is more often torn from the femur, and is rarely ruptured. Discussion of article see article 1877BrookeC . DISLOCATIONS OF THE THIGH: THEIR MODE OF OCCURRENCE AS INDICATED BY EXPERIMENTS AND THE ANATOMY OF THE HIP-JOINT. BY HENRY MORRIS, M.A., M.B., F.R.C.S., ASSISTANT SURGEON TO, AND LECTURER ON ANATOY1 AT, THE MIDDLESEX HOSPITAL. Received January 9th-Read February 13th, 1877. RECENTLY, whilst making various dissections of the hip-joint, the usually accepted doctrine that dorsal and ischiatic dislocations of the femur occur when the thigh is in a position of adduction appeared to me as very improbable, on anatomi...

1849QuainJ

Fragments from the book by Jones Quain (fifth edition): Elements of anatomy Vol. 1 (1849), the first edition was published in 1828. The author writes about the anatomy of the ligamentum capitis femoris (LCF) and mentions synonyms. Quote p. 278 THE HIP-JOINT. This is a true ball-and-socket joint, in which the globular head of the femur is received into the acetabulum or cotyloid cavity. The articulating surfaces are covered by cartilage in the greater part of their extent. It is deficient, however, at the bottom of the cavity, and also a little beneath the central point of the head of the femur; the latter marking the insertion of the round ligament, the former a shallow fossa for the lodgment of the structure which has been called the synovial gland. The connecting means in this articulation are three ligaments, viz. a capsular, cotyloid, and interarticular ligament, together with a synovial membrane. Fig. 147. Ligaments of the pelvis and hip-joint. The view is t...
