1742WeitbrechtJ

The author describes the prismatic shape of the ligamentum capitis femoris (LCF) and the areas of its attachment. A summary of the Latin text is available in the translation of the treatise made by the Royal College of Surgeons in Ireland: «Round or Interarticular Ligament is perfectly concealed in the cavity of the acetabulum ; it is rather of a triangular or prismatic form, one edge of it looks upwards, another downwards, and the third is lost in the adipose substance ; it becomes rounder and more contracted as it approaches the depression in the head of the femur, into which it is inserted.» (see 1829,1833WeitbrechtJ).

§. 7. Ligamentum, vulgo teres f dictum (g) intra acetabuli cauitatem fepultum, proprie, quando tenditur, tamquam prisma propemodum apparet, tribus lateribus comprehenfum, et tribus lineis angularibus terminatum. Linea prima (i) terminatur in angulo fuperiore, quem fupercilium coxae cum ligamento transuerfali interno (§. 3.) conficit; altera terminatur in angulo acetabuli inferiore, iuxta eiusdem ligamenti infertionem; tertia denique (k) in membrana adipofo-glandulofa (m) obliteratur. His igitur lineis includuntur tria latera. Lateris primi (b) bafis inter lineam primam et fecundam adnafcitur ligamento transuerfali interno, fecundum eius longitudinem et in fitu naturali accumbit capiti femoris. Latus fecundum (g) inter lincam primam et tertiam in membrana praedicta glandulofa diffunditur, et accumbit concamerationi acetabuli. Latus tertium, inter lineam fccundam et tertiam adnafcitur fpatio, quod eft inter finem ligamenti transuerfalis et angulum cauitatis inferiorem, et pro vario fitu capitis femoris etiam apprimitur acetabulo. Quo propius ad caput hoc accedit, eo magis figuram teretem nancifcitur. Denique in finu, qui tamquam fedes polaris (g) huius globofi capitis eft, coanguftata maffa oblique innafcitur, poftquam incifuram leuem commodioris fedis cauff transierat; in quo finu ipfo per quaedam breuia retinacula ligamentofa cohiberi videtur.

Ligamentum teres capitis femoris. Description. Fig. 56. §. 7. The ligament, commonly called teres (f) (g), located within the acetabular cavity, when stretched, resembles a prism with three sides bounded by three angular lines. The first line (i) terminates at the upper angle, formed by the brow of the hip joint and the internal transverse ligament (§. 3.); The second terminates at the lower angle of the acetabulum, near the insertion point of the same ligament; The third (k) disappears in the capsule of the adipose gland (m). Thus, these lines define three sides. The first side (b) lies between the first and second lines, connecting to the internal transverse ligament, extending along it and naturally applying to the head of the femur. The second side (g) between the first and third lines extends within the mentioned glandular capsule and lies deep in the acetabular cavity. The third side between the second and third lines corresponds to the space between the end of the internal transverse ligament and the lower angle of the cavity and, depending on the position of the femoral head, may press against the acetabular cavity. The closer to the head, the more the ligament acquires a rounded shape. Finally, at the deep pit, which serves as a kind of seat on the spherical head, the ligament mass narrows and attaches obliquely after entering the smooth depression, presumably, in this depression, the ligament is held by some short fibers.

ILIOTIBIAL TRACT & LCF

ILIOTIBIAL TRACT & LCF There is an opinion that the iliotibial tract, like the ligamentum capitis femoris (LCF), provides pressing of the acetabulum to the lower surface of the femoral head. I think that this is not true. The tract is located above and lateral to the center of rotation of the hip joint. Its force vector, like the force vector of the abductor group of muscles, presses the acetabulum to the upper part of the femoral head, which increases the load on it. The ligamentum capitis femoris acts in the opposite direction. Below is a diagram for a single-support position. #ligamentum_teres #hip #biomechanics #ligamentum_capitis_femoris Publication in the facebook group 04/12/2025. ...

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...

Works of art that mention ligamentum capitis femoris (LCF) are extremely rare. One such work is the poem «Der Schauende» ( He Who Visions, The Seer, The Man Watching, The Beholder) b y Rainer Rilke. Below is the original text in German. Der Schauende 1. Ich sehe den Bäumen die Stürme an, die aus laugewordenen Tagen an meine ängstlichen Fenster schlagen, und höre die Fernen Dinge sagen, die ich nicht ohne Freund ertragen, nicht ohne Schwester lieben kann. 2. Da geht der Sturm, ein Umgestalter, geht durch den Wald und durch die Zeit, und alles ist wie ohne Alter: die Landschaft, wie ein Vers im Psalter, ist Ernst und Wucht und Ewigkeit. 3. Wie ist das klein, womit wir ringen, was mit uns ringt, wie ist das groß; ließen wir, ähnlicher den Dingen, uns so vom großen Sturm bezwingen, - wir würden weit und namenlos. 4. Was wir besiegen, ist das Kleine, und der Erfolg selbst macht uns klein. Das Ewige und Ungemeine will nicht von uns gebogen sein. Das ist der Enge...

According to the author, the ligamentum capitis femoris (LCF) is intended to prevent dislocations in all directions. A. Cooper discusses traumatic obturator dislocation of the hip joint and LCF injury in more detail. Cooper A.

A Novel Technique for Proximal Fixation

Arkhipov SV. A Novel Technique for Proximal Fixation of Ligamentum Capitis Femoris Reconstruction: The Gifts of the Magi for Orthopedic Surgeons. About Round Ligament of Femur. January 14, 2026. DOI: 10.13140/RG.2.2.25269.33763 https://roundligament.blogspot.com/2026/01/the-gifts-of-magi-for-orthopedic.html Abstract Purpose: To describe an experimental technique for proximal fixation in ligamentum capitis femoris (ligamentum teres femoris; LCF) reconstruction using pubic and ischial portions anchored in corresponding pelvic bone tunnels, tested on synthetic hip joint models, and to propose it’s for arthroscopic application with visualization via an inferior portal and femoral tunnel. Methods: Synthetic polyurethane bone analogs (Synbone) of the pelvis and proximal femur were used to fabricate hip joint models. Acetabular cartilage analogs were created from self-curing plastic compound. Femoral tunnels were drilled along the neck axis from the subtrochanteric region below the tub...

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.

Short retelling of chapter 13 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 13. PROPHETIC DREAMS After his wanderings and battles, Abraham settles in “Mamre’s oaks in Hebron.” Following these events, he experiences a divine “word in a vision” and a dream promising him lands “from Egypt’s river to the great river, Euphrates.” His family relocates to a desert along the Shur road, near the well “Beer-Lahai-Roi,” between Kadesh and Bered. In another divine appearance, Abraham is commanded to circumcise all males’ foreskins, rename Sarai as Sarah, and is told he’ll father a child at 100, despite Sarah’s barrenness at 89. That day, Abraham circumcises his son Ishmael, household males, and, at 99, himself. In Mamre’s oaks, during “daytime heat,” a mirage foretells fatherhood. The dream shifts, showing Sodom and Gomorrah’s destruction and Lot’s miraculous rescue. ...
