| Résumé : | Extensometric recording of cortical deformations enabled comparison of the mechanical responses of the diaphyses of tibia and fibula to centered and decentered stresses such as occur in genu varum and genu valgum. The tibiofibular frame, normally subjected to sagittal flexion, flexes in different ways in these pathological conditions: in genu varum, inward and backward and in genu valgum, outward and foreward where the tibia is concerned; the inverse applies to the fibula. Owing to the abnormal stresses to which the knee is exposed, the diaphyseal tensions, abnormal both as regards intensity and as regards distribution, bring about the cortical adaptations which radiology will reveal. Under the centered knee, the fibula plays a real mechanical role; more than in genu varum and genu valgum, it shares the weightbearing with the tibia. |
