    Description / Table of Contents: Résumé La veine brachiocéphalique gauche rétro-aortique est une entité anatomique rare. Une analyse rétrospective a été réalisée sur 5 218 cardiopathies congénitales traitées entre 1982 et 1998 dans un département médico-chirurgical de cardiologie pédiatrique. Une veine brachiocéphalique gauche rétro-aortique a été mis en évidence chez 27 patients soit une incidence de 0,5 %. La cardiopathie principale était une tétralogie de Fallot dans 25 cas (93 %). Parmi ces 25 cas de tétralogie de Fallot, l'arc aortique était droit dans 19 cas (70 %). Le diagnostic paraclinique de cette anomalie est aisé par échocardiographie à condition de la rechercher. Dans cette série, 6 cas (22 %) ont été découverts pendant la chirurgie sans diagnostic échographique préalable. L'origine embryologique de la veine brachiocéphalique gauche rétro-aortique est différente de celle de la v. brachiocéphalique dans sa forme anatomique classique. Elle provient des plexus transverses inférieurs (et non supérieurs) mettant en communication les deux veines cardinales antérieures. Une des principales conséquences cliniques de cette anomalie est la confusion possible avec d'autres structures vasculaires en particulier l'a. pulmonaire droite. Une telle confusion peut être à l'origine d'indications chirurgicales non appropriées. Le diagnostic différentiel est facilité par l'utilisation du Doppler : le flux veineux est biphasique et rythmé par la respiration alors que l'enregistrement Doppler d'une a. pulmonaire donne un flux artériel systolique caractéristique.
    Notes: Summary A left retro-aortic brachiocephalic vein is a rare anatomic entity. A retrospective study was made of 5218 congenital cardiopathies treated between 1982 and 1998 in a medico-surgical department of paediatric cardiology. A left retro-aortic brachiocephalic vein was demonstrated in 27 patients, i.e. an incidence of 0.5%. The chief cardiopathy in these patients was a tetralogy of Fallot in 25 cases (93%). Among these 25 cases of Fallot's tetralogy the aortic arch was rightsided in 19 cases (70%). The paraclinical diagnosis of this anomaly was facilitated by ultrasonography, provided it was sought for. In this series 6 cases (22%) were discovered during surgery without previous ultrasound diagnosis. The embryological origin of the left retro-aortic brachiocephalic v. differs from that of the venous trunk in its classical anatomic form. It derives from the inferior (but not superior) transverse plexuses, connecting the two anterior cardinal veins. One of the main consequences of this anomaly is its possible confusion with other vascular structures, particularly the right pulmonary artery. Such confusion may give rise to inappropriate surgical procedures. The differential diagnosis is facilitated by the use of the Doppler: the venous flow is biphasic and regulated by respiration, whereas the Doppler recording from a pulmonary artery is that of a characteristic systolic arterial flow.

    Description / Table of Contents: Résumé En chirurgie prothétique de l'articulation coxo-fémorale, il est fondamental de recentrer la hanche pour recréer la balance du muscle moyen fessier. La détermination du centre de rotation de la hanche est difficile si les deux articulations coxo-fémorales sont détruites. A partir de 70 radiographies du bassin de face debout, les auteurs mesurent la position du centre de la tête fémorale par rapport à la ligne de Kohler et par rapport à la ligne TD, unissant les deux U radiologiques. Sur cette même radiographie, ils définissent des index horizontaux et des index verticaux. L'analyse descriptive de ces paramètres met l'accent sur l'influence du sexe sur les coordonnées du centre de rotation de la hanche. Les auteurs mettent en évidence des corrélations statistiques entre les coordonnées de ce centre de rotation de l'articulation et certains index horizontaux et verticaux. Il en résulte que la connaissance de ces index suffit à définir la position théorique du centre de rotation. La méthode est comparée aux autres principes énoncés dans la littérature. Le procédé trouve sa place en clinique, dans le cadre de la planification pré-opératoire des reconstructions prothétiques de l'acétabulum, chaque fois qu'il est détruit de façon bilatérale (séquelle traumatique, luxation congénitale, descellement acétabulaire, etc.).
    Notes: Summary In prosthetic surgery of the hip joint it is essential to recenter the hip to recreate the leverage of the gluteus medius muscle. Determination of the center of rotation of the hip is difficult if both hip joints have been destroyed. On the basis of 70 frontal radiographs of the hip in the standing position, the authors measured the position of the center of the femoral head in relation to Köhler's line and the TD line joining the two radiological Us (“tear-drops”). On the same radiograph they defined the horizontal and vertical indices. The descriptive analysis of these parameters stresses the influence of sex on the coordinates of the center of rotation of the hip. The authors demonstrated the statistical correlations between the coordinates of this center of rotation of the joint and certain horizontal and vertical indices. It emerged that knowledge of these indices suffices to define the theoretic position of the center of rotation. The method is compared with other principles set out in the literature. The procedure has a clinical application in the context of preoperative planning of prosthetic reconstruction of the acetabulum, whenever it is destroyed bilaterally (after trauma, in congenital dislocation or acetabular loosening, etc).

    Notes: Abstract Based on two orthogonal radiologic views, the authors present a morphometric study of the talocrural joint. In 50 normal subjects, 10 parameters were measured and divided into 3 groups: the distal tibial joint surface parameters, the malleolar parameters and the talar parameters. These parameters were treated in both a descriptive and a correlative analysis. If the talocrural joint is a hinge joint whose talar articular surface can be simplified and classed as a cylinder segment, it is possible to calculate its curve radius. Then the correlative analysis allows to define the talar parameters and the corresponding parameters of the distal tibial joint surface. The malleolar parameters are independent factors. This study is the first morphologic analysis to serve as a basis for an ankle arthroplasty.

    Description / Table of Contents: Résumé A partir de deux incidences radiologiques orthogonales, les auteurs proposent une étude morphométrique de l'art. talo-crurale. Sur une population de 50 sujets non pathologiques, dix paramètres ont été mesurés et répartis en trois groupes : le groupe des paramètres de la surface articulaire distale du tibia, le groupe des paramètres malléolaires, le groupe des paramètre du talus. Ces paramètres ont fait l'objet d'une analyse descriptive et d'une analyse corrélative. Si l'art. talo-crurale est une ginglyme dont la surface articulaire du talus peut être simplifiée et assimilée à un segment de cylindre, les auteurs, par le calcul, peuvent en définir le rayon de courbure. L'analyse corrélative permet alors de définir les paramètres du talus et les paramètres correspondant de la surface articulaire distale du tibia. Les paramètres malléolaires en restent indépendants. Ce travail est une première analyse morphologique pour concevoir une arthroplastie de cheville.

    Notes: Conclusion La position anormale rétro-aortique de la VBCG est une anomalie rare. Cette anomalie est le plus souvent retrouvée chez les patients porteurs d'une tétralogie de Fallot. Bien que cette malformation n'ait pas de répercussion physiopathologique en ellemême, sa recherche échographique doit être systématique. L'enregistrement Doppler permet d'éviter toute confusion avec d'autres structres vasculaires en particulier l'a. pulmonaire droite.

    Notes: Abstract Unilateral weight bearing was simulated on 12 cadaver knees to quantitate anterior tibial translation (ATT) after anterior cruciate ligament (ACL) transection and to asses the role of the posteromedial structure and the hamstrings in controlling laxity. With the ACL intact, ATT was 3.5±2.8 mm in extension and 4.3±3.6 mm at 60° flexion. After sectioning the ACL, ATT was 6.5±4.7 mm in extension and 17.5±10 mm at 60° flexion (P=0.001). Applying a force in the hamstrings was unable to correct the pathological ATT observed after ACL section. Partial medial meniscectomy did not increase ATT after the ACL section. Disinsertion of the posterior horn of the medial meniscus and total medial meniscectomy increased ATT significantly compared to isolated ACL section. After ACL transection, sectioning the meniscotibial fibers or posteromedial capsule significantly increased ATT (6.5±0.5 mm in extension). Section of the postero-oblique ligament or popliteus tendon had no effect on ATT.
