Das runde Band (lig. teres, s. rotundum) ist ein konischer Bündel von Sehnenfasern, die in der Gegend des Pfannenausschnitts vom inneren, oberen und unteren Theil der Pfanne und dem angegebenen inneren Querbande entspringen, und von ihrem Ursprunge an, von einem Ueberzuge der Synovialhaut des Gelenkes umgeben, convergirend in Form eines rundlichen Stranges in der Grube des Kopfes des Schenkelbeins sich befestigen (Tab. III. Fig. VII. 11. 12. 13, 14). Diess Band trägt dazu bei, den Kopf des Schenkelknochens im Pfannengelenke zu erhalten, und seine zu weite Entweichung nach rückwärts, und nach abwärts, wenn der ganze Schenkel im Hüftgelenke frei hängt, zu verhindern. Doch ist es zu lang und zu nachglebig, um für sich die Entweichung des Kopfes aus dem Hüftgelenke zu verhindern. Zur Erhaltung des Schenkelkopfs im Hüftgelenke tragen auch das Kapselband, die Muskeln die vom Becken entspringen, und an den Oberschenkel gehen, und wahrscheinlich auch der Druck der äussern Luft bei. Durchschneidet man die Schenkelmuskeln, die vom Becken entspringen, so kann man den Schenkelkopf, ohne Zerreissung des runden Bandes, nach unten und innen aus der Pfanne hervorziehen. Der Raum zwischen der innern Oberfläche des Hüftgelenks und der dasselbe einschliessen. den Kapselhaut ist grösser, als der cubische Inhalt des darin enthaltenen Kopfes und Halses des Oberschenkelknochens; der zwischen beiden übrige Raum kann nicht vollkommen durch Synovialflüssigkeit ausgefüllet seyn, so gross ist die in dieser Gelenkhöhle enthaltene Quantiät von Synovialflüssigkeit nicht: daher muss ein Theil dieser Flüssigkeit in dieser Höhle in Dunstform enthalten seyn. Dasselbe ist der Fall vom Serum in allen Höhlen, ja selbst in dem interstitiellen Zellengewebe aller Organe und selbst der äussern Haut befindet sich etwas seröse Flüssigkeit in Dunstform, daher kömmt zum Theile der Turgor vitalis, die Elasticität solcher Organe. Solche warme dunstförmige Flüssigkeit in inneren Höhlen von Gelenken ist specifisch leichter, als die äussere atmosphärische Luft, daher diese nach anerkannten physischen Gesetzen gegen die Umgebung solcher Höhlen einen Druck ausüben muss. Der das Hüftgelenk zunächst umgebende Theil ist der Oberschenkel, seine Muskeln und Haut, und es ist so schon nach physischen Gesetzen keinem Zweifel unterworfen, dass der Druck der äusseren Luft auf diese Umgebung selbst dazu beiträgt, den Kopf des Oberschenkels in seiner Lage im Hüftgelenke zu erhalten. Diess hat Herr Dr. Eduard Weber in der Versammlung deutscher Naturforscher zu Bonn 1835 [see too 1836WeberW_WeberE] in einem Vortrage in der dritten öffentlichen Versammlung erkläret, worin er nachwies, dass der Kopf des Schenkelknochens auf dieselbe Weise in seinem Hüftgelenke durch den Druck der atmosphärischen Luft erhalten werde, als durch denselben das Quecksilber in der Barometerhöhle getragen wird. Durch Versuch an einer Leiche bewies er in der anatomischphysiologischen Section, dass der Kopf aus seiner Gelenkhöhle durch die Schwere des Schenkels etwas austrat, wenn das Hüftgelenk angebohrt, und dadurch der Druck der äussern Luft auf das offne Hüftgelenk aufgehoben wurde. Wurde aber der Kopf reponirt, die gemachte Oeffnung durch Druck eines Fingers auf dieselbe geschlossen, so wurde der Kopf durch den Druck der äussern Luft so lange wieder im Pfannengelenke getragen, als die Oeffnung verschlossen blieb, sauk aber wieder aus demselben hervor, wenn die Oeffnung durch Entfernung des schliessenden Fingers wieder frei wurde *).

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.                                                                              ...

1836WeberW_WeberE

  We present fragments from the book that laid the foundation of biomechanics of the hip joint considering the ligamentum capitis femoris (LCF). The authors experimentally proved that this structure is situated in the frontal plane when the body is in a vertical position. Analysis of observations showed that when standing on one leg, the LCF and the anterior portion of the iliofemoral ligament (pars descendens lig. iliofemoralis) are stretched and hold the pelvis. These ligaments counteract the weight of the body along with the head of the femur on the same side. The insight of the Weber brothers was later developed in the works of H. von Meyer (1856) , W. Turner (1857) , and W. Savory(1874) . Weber W, Weber E. Mechanik der menschlichen Gehwerkzeuge: eine anatomisch-physiologische Untersuchung. Gottingen: Dietrichsche Buchhandlung, 1836.

1922LeeserI

  A fragment of the Book of Genesis tells about the journey of the family of Patriarch Jacob from Charan to Canaan (Gen. 31:1 – 33:20). The translation into English from of the Masoretic Hebrew text of the Torah was done by Isaac Leeser ( 1922 LeeserI ). «Most scholars agree that the texts now found in Genesis began to be written down sometime after the establishment of the monarchy in Israel in the tenth century BCE» (1992SuggsMJ_MuellerJR). A selected passage from an ancient work mentions for the first time in history the injury of the ligamentum capitis femoris (LCF) of a person is mentioned (Gen. 32:26,33). In the original Hebrew source this anatomical element is referred to as «גיד» (gheed, gid)  ( Bereshit 32:33 ;  1923, 2004PreussJ;  2019ArkhipovSV_SkvortsovDV ;  2020ArkhipovSV_ProlyginaIV ).  This term was recorded in writing long before Hippocrates of Kos (V-IV cent. BCE) who used the concept «νεῦρον» to designate LCF (1844LittréÉ). It is not known...

2013ClaytonM PhiloR

  Fragment from the book Clayton M, Philo R. Leonardo da Vinci: The mechanics of man (2013). The authors describe a drawing by Leonardo da Vinci depicting the insertion site of the ligamentum capitis femoris (LCF). The drawing was created in the winter of 1510-1511 in Milan while studying the anatomy of the human body ( 1510Leonardo_da Vinci ). Quote p. 90 The slightly enlarged upper head of the fibula and the blunted appearance of the styloid processes at the end of the tibia and fibula may have resulted from using freshly prepared bones, with portions of ligaments and cartilage remaining, rather than dried bones. A small piece of ligament seems to be visible on the head of the femur in the drawings below, at upper right and at upper center, and the patella drawn in isolation at upper left appears to have some of the patellar ligament remaining on its lower edge.

Set of Classifications

  General Classification of LCF Pathology Version : 20240420 Annotation Analysis of literature data and our own morphological observations allowed us to propose a General Classification of LCF Pathology. Introduction In Russia, the initial attempts to classify pathology of the ligamentum capitis femoris (LCF) were made by morphologists. L.I. Gaevskaya distinguished three types of LCF: 1) long and thick (length 41–51 mm, thickness 5 mm), 2) short and thin (length 10–20 mm, thickness 1 mm), 3) long and of small thickness (length 43–45 mm, with a thickness of 3 mm, and length 28–30 mm with a thickness of 4–5 mm) (1954 ГаевскаяЛИ ). V.V. Kovanov, A.A. Travin identified three varieties of histological structure of LCF: 1) with a predominance of loose connective tissue; 2) with a predominance of dense connective tissue; 3) with a uniform distribution of loose and dense connective tissue ( 1963 КовановВВ _ ТравинАА ). The development of arthroscopic surgery has made it possible to i...
