2. Ligament rond (Fig. 52, 3). Ce ligament à la forme d'un triangle aplati de dehors en dedans, dont la base correspond au ligament transverse de l'acétabulum, la pointe à la dépression de la tête du fémur. Assez variable comme force et comme disposition, il s'insère en bas aux deux bords de l'échancrure cotyloïdienne, à la partie voisine de l'arrière-fond et au ligament transverse. Il est entouré par la synoviale et présente dans son intérieur des vaisseaux allant se rendre à la tête du fémur. La face interne est en rapport avec l'arrière-fond de la cavité cotyloïde, auquel il est rattaché par un repli synovial, sa face externe avec la tête du fémur.

Vaisseaux et nerfs. Les artères viennent des artères circonflexes interne et externe, fessière, ischiatique et obturatrice; cette dernière fournit un rameau qui pénètre par l'échancrure cotyloïdienne dans le ligament rond et va gagner la tête du fémur par les trous de sa dépression centrale. Les nerfs sont en avant, des filets venant de la branche du nerf obturateur, qui va à l'obturateur externe, et des branches musculaires du nerf crural; en arrière, des filets fournis par le nerf ischiatique et par le nerf sciatique, soit directement, soit par sa branche du carré crural.

3. Adduction et abduction. Ces mouvements se passent autour d'un axe antéropostérieur perpendiculaire au précédent et ont aussi une excursion de 90°; l'abduction est limitée par la rencontre du rebord cotyloïdien et du col; l'adduction par la tension du ligament rond; toutes deux comme la rotation, soit en dedans soit en dehors, par la tension du ligament de Bertin; il en résulte que ces quatre mouvements sont incompatibles avec l'extension forcée et ne peuvent se faire qu'avec la flexion, qui relâche le ligament antérieur. C'est dans l'abduction que la tête du fémur présente le plus de points de sa surface en dehors de la cavité.

Le rôle du ligament rond est interprété différemment par les auteurs; les uns, se basant sur son absence constatée dans quelques cas, sur son peu de résistance dans quelques autres, le regardent comme un simple repli destiné à supporter des vaisseaux (Henle); les autres, à cause de la tension incontestable qu'il présente dans l'adduction, lui donnent pour rôle principal de limiter ce mouvement. Il est tendu en outre dans la rotation en dehors, la cuisse étant fléchie; ainsi, par exemple, il maintient le genou élevé lorsqu'on place le bord externe du pied sur le genou du côté opposé.

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...

  Fragments of the book Cooper AP. Lectures on the Principles and Practice of Surgery (1835) dedicated to ligamentum capitis femoris (LCF). The author discusses LCF injury during hip dislocation and notes the important role of its blood vessels in supplying the femoral head.   Quote p. 577 DISLOCATIONS OF THE HIP JOINT … It generally happens when the thighs are widely separated from each other, that the ligamentum teres and capsular ligament are torn through, and the head of the bone is situated on the obturator externus muscle at the inner and back part of the thigh. Quote pp. 584-585 ON DISLOCATIONS OF THE THIGH BONE … But the third and principal reason is, the almost entire absence of ossific union in the head of the bone when detached from its cervix. The principal supply of blood to the head of the bone being derived from the ligamentum teres, which has only a few minute vessels ramifying from it on the bone, the natural supply of blood for the neck and head ...
