General notions of functional anatomy. Review of the literature concerning the elastometric study of tendons and of the ligaments, as well as the histologic study of the fibrous structures as a whole. It demonstrates the reliability of these methods and the interest of the tissular properties, showed up by the latter.
Each fibrous structure of the wrist has been studied by elastometric methods. These lead to a classification superposable to the functional classification. They show up the big mechanical differences between to tendons and but to ligaments. The former are 3 to 5 times as solid, but 3 to times less extensible than the latter. These are divided into 3 groups the more fragile as much as they are stretchable. The aponeuroses have their place between tendons and ligaments, but their properties are very closer to the latter.
Each fibrous structure of 10 wrists of fresh cadavers has been the subject of a study without preparation with the surgical microscope, then of an histological study. These have been compared with the elastometric study of the controlateral homologous structure. The diameter of the fascicles, the length and the amplitude of the undulations of the collagen fibers had shown particularly characteristic. The comparison between both series shows up the close relation between the mechanical properties and the architecture of the fascicles, which is also perfectly measurable. It shows up the big differences between ligaments and tendons. The histological study of the tendons and ligaments of 4 other wrists, submitted to manoeuvres of stretching, of rupture and of incurvation, reinforces these results. The therapeutic consequences are considered.
The authors describe a modified radiological lateral view according to the points of tangency of the radial articular surface. The view allows the separate study of the radio-scaphoïd and the radiolunate joint spaces, which are otherwise superimposed on a classical side view. This view has a clinical interest especially when treating malunion deformities.
