dc.description.abstractEnEntheses occupy an important place among the skeletal markers of activity and have been explored since the 1980s using clinical, radiological, histological and osteo-archaeological methods. Some studies have highlighted age-related variations in the morphology of enthesial changes: localised cortical osteolysis is frequently observed in immature skeletons, in contrast to the osteophytic processes seen in adults. The development of μCT and 3D imaging methods is leading to a better understanding of these mechanisms. Recent studies have focused on the microarchitecture of growing bone, both normal and pathological, in order to better understand its variability. For entheses, the microarchitecture of the cortical canal network was studied to determine the structural variability between normal insertion, metabolic enthesopathy and mechanical enthesopathy, but the trabecular structure under enthesial changes has not yet been studied in detail. Insertional cortical osteolysis (ICO) is interpreted either as normal developmental variations or as the result of biomechanical overload on a growing skeleton. This hypothesis should be confirmed by the orientation of the trabecular bone under the enthesis, which should follow the main direction of biomechanical forces, in accordance with Wolff’s law. This pattern needs to be clarified using 3D reconstructions of μCT analyses of these ICOs.
