[Radiologic examination of the knee and ankle in stress positions (author's transl)]. / Intérêt des examens radiologiques en position de stress des genoux et des chevilles.

The serious serious sequelae of sprains of the knee and ankle makes it imperative for the therapist to have an early and precise diagnosis. The authors propose a means of exploring these joints with the aid of a simple set up. This new technology allows the radiologist, secure from direct or indirect radiation, to carry out a standardized examination of the joint, usually unilaterally, and to make his interpretation more easily and more precisely. This method of x-raying in the stress position has its major indication in emergencies, but is equally useful in non emergencies, accomplishing a veritable over-all evaluation of the joint: varus, valgus, preternatural anterior and posterior sliding motion. The interpretation, based on direct reading of the films, differentiates the normal condition from physiological relaxation and mild and severe sprains. Naturally this method is to be used only after taking standard routine views to rule out any fractures.

[Comparative study of computed x-ray tomography and saccoradiculography in the diagnosis of early lumbar disk herniation. Apropos of 50 surgically-proven cases]. / Etude comparative du scanner et de la saccoradiculographie dans le diagnostic des hernies discales lombaires inaugurales. A propos de 50 cas vérifiés chirurgicalement.

Comparison of diagnostic accuracy using the two methods showed scanner imaging to provide superior results, with confirmation of herniated disc in 90 p. 100 cases based on purely discal semiological features. Limitations of the method result from the absence of epidural fat (narrow lumbar canals). A new hierarchy of radiological explorations in resistant lumbosciatica is proposed.

[Value of transfontanelle echography in the diagnosis and surveillance of pericerebral effusions]. / Intérêt de l'échographie transfontanellaire dans le diagnostic et la surveillance des épanchements péricérébraux.

The authors report 3 cases of peri-cerebral fluid collection in infants. They emphasize the importance of anterior fontanelle real-time ultrasonography to set up the diagnosis and for the follow up of these patients. From a technical point of view they recommend the use of a water bag to facilitate the examination.

[Echographic aspects of biliary lithiasis and its complications]. / Aspects échographiques de la lithiase biliaire et de ses complications.

Ultrasonic appearances of various types of gallbladder stones are described and findings on ultrasonic imaging of the main complications of biliary lithiasis analyzed. New possibilities for examination of the principal biliary pathway are being opened up by progress in improving resolution of the ultrasonoscope and by advances in knowledge of ultrasonic anatomy of the biliary tracts.
