简要总结
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.
详细描述
Hereditary Multiple Osteochondromas (HMO) disease, also known as 'Hereditary Multiple Exostosis', is a rare autosomal dominant musculoskeletal disorder whose prevalence is estimated at 1:50000. It is characterised by benign osteo-cartilaginous tumours called 'osteochondromas' or 'exostoses', cartilage capped bony outgrowths that originate from the perichondrium of long bones and from the surface of flat bones. The development and growth of exostoses occur in parallel with the growth of the subject and then stop at skeletal maturity. HMO is characterized by phenotypic heterogeneity and the most important complication is malignant transformation of osteochondroma towards secondary peripheral chondrosarcoma, which is estimated to occur in 0.5-5%. In most case, the disease is characterized by a broad-spectrum of mutations in the EXT1 and EXT2 genes coding for transmembrane glycoproteins with glycosyl-transferase activity.
Patients with HMO are subject to functional and postural alterations of the musculoskeletal system caused by bone deformities that begin to appear at an early age. The characterization and monitoring of residual mobility is essential to objectively quantify the motor and morphological deficit and to understand the mechanisms of action and evolution of this pathology. To date, there are no studies in the literature on the instrumental characterisation of OM. Furthermore, although skeletal structure deformities are one of the main causes of functional alterations, studies on the description and instrumental characterisation of macroscopic morphological alterations are limited. The expected results are morphological data (shape, position, size and numerosity) of osteochondromas and functional data (range of motion of the joints affected by the pathology). Other expected results are: accuracy and repeatability of the instruments to be used for monitoring pathology; an overall evaluation of the experience by means of an evaluation questionnaire; information on the feasibility of the pilot study for the implementation of a study on a larger cohort; identification of new prevention and treatment strategies in patients with rare diseases clinically similar to OM (e.g. metachondromatosis) or for other skeletal diseases that are not rare but widespread (e.g. osteoarthritis).

结局指标
主要结局
Functional motor assessment
时间窗: From subjects enrollment to the end of the assessment. Patients repeat these activities after 12 months from the first evaluation, while healthy subjects carry out the same activities of unhealthy population only once.
Analysis of the following motor tasks is executed: planar linear walking, overcoming a step/obstacle, standing up/ sitting down from a chair. Analysis of these movements includes: 1. joint kinematics obtained through inertial sensors (IMU) that are attached to the body segments by means of bands or double-sided tape; 2. joint kinetics (joint torque and powers) obtained from ground reaction force data, measured with the force platforms on the laboratory floor and from joint kinematics; 3. plantar pressure maps by means of a baropodometric platform positioned on the laboratory floor that will measure plantar pressure data in static and dynamic.
Anthropometric parameters assessment
时间窗: From subjects enrollment to the end of the assessment. Patients repeat these activities after 12 months from the first evaluation, while healthy subjects carry out the same activities of unhealthy population only once.
Body measurement using 3D scanning is carried out. The subject should wear underwear or short and tight clothing. The subject should remain as still as possible in a standing position while being scanned.
次要结局
- Evaluation of experimental protocols using simplified instrumentation(through study completion)
- Evaluation questionnaire(The questionnaire is administered to the cohort of patients at the first acquisition and at 12-month follow-up.)
- Assessment of quality of life and balance perception of hereditary multiple osteochondromas patients(through study completion)
