Hereditary Multiple Osteochondromas

The main purpose of the study is the characterization of functional and morphological alterations due to multiple osteochondromas in a pediatric and adult population through the identification of relevant anthropometric and functional parameters. The morphological and functional data, supplemented with clinical and postural data, will allow the characterization of the disease with an holistic approach that can provide important information to properly assess timing for surgical treatments and to improve the quality of life of these patients. Another goal of the study is the assessment and the validation of novel instruments and tools to measure joint mobility and bone deformity. These instruments should be easy-to-use and designed to be operated locally by the patients themselves and/or in small clinics by operators with little training and no specific high-technical knowledge. The final goal of the study is the assessment of the quality of life and balance perception of patients, using questionnaires.
