The study analyzed the overall microstructure of eleven fresh human ligamentum teres (LT) specimens. The authors suggest that the LT «... hould no longer be considered a developmental vestige, as there is evidence to suggest that it has both mechanical and biological functions within the hip joint. As such, any surgical procedures should aim to minimize excessive damage to this structure as far as possible, so as to minimize any potential loss of function.»

IMPROVING POSTOPERATIVE COMFORT...

Improving Postoperative Comfort and Increasing the Reliability of Hip Prostheses by Supplementing with Artificial Ligaments: Proof of Concept and Prototype Demonstration S.V. Arkhipov, Independent Researcher, Joensuu, Finland CONTENT [i] Abstract [ii] Introduction [iii] Materials and Methods [iv] Results and Discussion [v] Static Tests [vi] Dynamic Tests [vii] Prototype Fabrication and Testing [viii] Conclusion [ix] References [x] Application [i] Abstract The principle of operation of an experimental total hip endoprosthesis augmented with ligament analogs has been demonstrated in single-leg vertical stances and at the mid-stance phase of the single-support period of gait. The experiments were conducted on a specially designed mechatronic testing rig. The concept of the important role of the ligamentous apparatus is further illustrated by a set of demonstrative mechanical models. The...

Catalog. Classifications of LCF Pathology

The classifications are intended to systematize of ligamentum capitis femoris pathology and assist in the development of general approaches to its description, registration, analysis and treatment. Keywords ligamentum capitis femoris, ligamentum teres, ligament of head of femur, hip joint, histology, pathological anatomy, pathology, trauma INTRODUCTION In Russia, the initial attempts to classify pathology of the ligamentum capitis femoris (LCF) were made by morphologists. The development of arthroscopic surgery has made it possible to identify various, previously undescribed types of LCF pathology, which prompted the development of various modern classifications based on intraoperative observations. Analysis of literature data and our own morphological observations allowed us to propose a General Classification of the Ligamentum Teres Pathology, which has the form of a collection of classifiers, as well as a Classification of Functions of the Ligamentum Teres. The ...

The First Scientific Mention

European science has known the LCF for about 2500 years. It is the most important functional connection of the hip joint. The first person to describe the LCF was Hippocrates (c. 460-370 BCE). A written mention of the LCF is found in §1 of his treatise "On the Instrument of redactions". In our opinion, a book created in the library of the Asclepeion of the island of Kos. Hippocrates did not dissection of the human body, did not operate on the hip joint, did not have a CT scan and MRI. How he could discover the LCF? In our view, it is possible that Hippocrates treated a patient with an open hip dislocation.

1832MeckelJF

Fragments of the book Meckel JF. Manual of general, descriptive, and pathological anatomy (1832) dedicated to ligamentum capitis femoris (LCF). The author briefly discusses abnormalities of the LCF and its distal insertion. Quote p. 257 § 308. Among the deviations from the normal state, primitive deviations of the external form are rare, and usually attend anomalies of the other tissues. Among these we arrange, for instance, the absence of the tendons of the abdominal muscles, that of the ligaments of the vertebral column, and that of the dura mater of the brain and spinal marrow, &c., in a congenital fissure of the abdomen, of the vertebral column, and of the skull, and that of the tendons and the muscles of a finger, when the finger itself is wanting. But the fibrous organs are seldom deficient, when the other tissues with which they combine to form a part are present — for instance, the tendon alone of a muscle is rarely absent, or the tunica sclerotica, when the othe...
