Cervical Spine: Tricks and Traps

The cervical spine is always examined initially using standard radiographs, which often provide a sufficient basis for diagno- sis. Malformations, tumours, more frequently trauma, rheuma- tism, and even plain neck pain require a radiological exam- ination. The interpretation of radiological images is often difficult because of overlapping pieces of bone, the summation phe- nomena and the diversity of projections. In this book, two- or three-dimensional CTscans accompany the standard radiographs, serving as an excellent aid for com- prehension. It is almost as if the reader actually had the bones shown in the radiographs in his hands. From then on, everything becomes easy, superimpositions vanish, traps come to light, anatomy triumphs, and the images takes on life. Besanl$on, 1990 J .-F. BONNEVILLE, F.

It will serve as a guide and point of reference in our task of comprehending the interrelationships between the structures of the cervical spine. This radiograph correctly includes the entire area from the base of the skull to the cervicothora- cic junction. The soft tissues are clearly visible anteriorly, as are the extremities of the spinous processes posteriorly. In this case, with the subject looking straight ahead, is a slight, regular, physiological lordosis ofthe cervical column.
