[How to visualize one additional vertebra on profile radiographs of the cervical spine?]. / Comment gagner une vertèbre sur la radio de rachis cervical de profil?

The authors describe a simple technical trick allowing a better study of the cervical spine in subjects with a brevilineal morphology: this consists in placing a small sans block between, the patient's shoulder blades, while exerting the usual traction, thus causing appropriate backward displacement of the shoulders and clearing the lower cervical spine.

[Computed tomography in the evaluation of recent articular fractures of the calcaneus]. / Apport de la tomodensitométrie dans le bilan des fractures articulaires récentes du calcanéum.

After mentioning the results of a survey carried out on 28 patients suffering from recent calcaneus articular fractures, the authors point out 9 main points to take into account when a TDM analysis of these lesions is to be done: they recommend to practice a double obliquity incidence that seems to be an efficient guide for a therapeutic decision. They insist on the usefulness of the TDM examination provided it is undertaken after the operation and the removal of the osteosynthesis equipment.

Scanographic study of the calcaneus: normal anatomy and clinical applications.

To facilitate the interpretation of the scanographic findings in fractures of the calcaneus, the authors have achieved an anatomo-radiologic correlation in terms of the classical coronal, sagittal and horizontal planes. Clinically, the sagittal plane can be obtained only by reconstruction. The 2 other planes permit study of the sustentaculum tali and posterior talar surface only in different sections, without their respective relationships. The authors therefore suggest a new double-oblique view, practicable in the injured patient, with a forward tilt of 20 degrees and medial rotation of 35 degrees, perpendicular to the sinus tarsi. This serves for anatomo-radiologic correlation and shows both anatomic structures together. By itself, it provides as much information as the three classical views and appears adequate for the assessment of fractures.
