1823GerdyPN

The author mentions their observation of the displacement of the femoral head from the acetabulum outwards when the ligamentum capitis femoris (LCF) is stretched. Continuing experimental research, P.N. Gerdy discovered that the LCF, when stretched during adduction, also displaces the femur in the caudal direction (see 1833GerdyPN).

PROPOSITIONS

La luxation du fémur en haut et en dehors est plus facile que celle en bas et en dedans, surtout parce que le ligament interarticulaire tend à s enrouler autour de la tête du femur, dans une violente adduction et qu il tire l os en dehors. Je m en suis assuré par l observation directe.

ASSUMPTIONS

Dislocating the femur upwards and outwards is easier than downwards and inwards, especially because the intra-articular ligament tends to spiral around the femoral head during strong adduction and pulls the bone outwards. I confirmed this through direct observation. [see: 1801BellJ !]

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 role of the ligamentum teres in congenital dislocation of the hip (1970). The authors proposed an analogy for the role of the ligamentum capitis femoris (LCF) as a “ball and chain control” and noted that it can spontaneously reduce congenital hip dislocation. The text in Russian is available at the following link: 1970MichaelsG_MatlesAL . [ii] Original text Quote p. 199 Many papers in the literature have implicated the ligamentum teres as a hindrance to the late open reduction of a congenitally dislocated hip. Occasionally the ligamentum teres has been reported to be absent. However, in most cases it is hypertrophied and elongated. Our present knowledge confirms the fact that congenital dislocation of t...
