The author discusses differences in the relative strength and size of the ligamentum capitis femoris (LCF) in humans at different ages. The characteristics of LCF in seals and tapirs are described. For more information on LCF in these and other animals, see the author's article: Welcker H. Nachweiseines ligamentum interarticulare („teres“) humeri, sowie eines lig. teressessile femoris. Zeitschrift für Anatomie und Entwicklungsgeschichte ( 1877 ) . The text is prepared for machine translation using a service built into the blog from Google.

  «Prof. Partridge in his lectures on anatomy at King's College was accustomed to compare the Ligamentum Teres, in its function, to the leathern straps by which the body of a carriage is suspended on springs » ( 1874SavoryWS ). Perhaps Nikolai Pirogov listened to these lectures ( 1859PirogoffN ).   The analogy that Richard Partridge used could have arisen after reading the monograph Bell J. The Principles of Surgery (1801) . In it, the author depicted a cart and a pelvis resting on the head of one and two femurs. However, there is no mention of ligamentum capitis femoris (LCF) in the chart descriptions. References Savory WS. On the use of the ligamentum teres of the hip joint.

  We present a study dedicated to the experimental investigation of the function of the ligamentum capitis femoris (LCF). Wilhelm Braune established that the LCF prevents hip supination and adduction, especially during flexion. In the conclusion of the study, the author writes: "It also remains to determine in which body movements this ligament function plays a role, as it is currently unclear why the femur requires a special fixing device…". Apparently, Wilhelm Braune did not have time to find the answer, since his outstanding monograph on LCF does not say a word ( Braune W, Fischer O. Der Gang des Menschen (1895 books.google ) . Based on our own experiments on mechanical models and research, we believe that adduction and supination of the hip, along with flexion, are observed at the beginning of the single-support period of the step. At this moment, tension occurs in the LCF, allowing to reduce the load on the upper segment of the femoral head. The LCF is also stretched in
