Nowadays the most used treatment is early surgical treatment by the spinal instrumentation without graft called "growing rods". The use of growing rods in patients with progressive scoliosis requires several repeated surgeries (every 6 to 12 months) in order to follow the growth of children. These repeated surgeries lead to a significant increased risk of complications, that\'s why many teams around the world have been seeking solutions which allow to obtain a rod expansion without repeated surgery.\n\nThe purpose of our study is the evaluation of the use of medical device that will perform the correction of scoliosis and, at the same time, preserve the growth of the child\'s spine. In addition, the purpose of clinical investigation is to test the theory that distraction effort may be exercised without surgery thanks to traction manoeuvres and physiotherapy. This could allow to obtain in patients with progressive scoliosis, correction of spinal deformity while avoiding many repeated surgeries. Our reference device is growing rod "NEMOST". When implanted, NEMOST rod is immediately turned on, for correcting and maintaining the correction of spinal deformity. After implantation, depending on development in Cobb angle, one or more elongations can be made by sliding the notched portion of the rod in its tunnel by a distraction effort (traction equipments and physiotherapy).\n\nTherefore, the growth device NEMOST will allow to continue, on request, the correction of spinal deformity by performing a distraction by external manoeuvres on the notched part without the need for surgery.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '15 Years', 'minimumAge': '5 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patient from 5 to 15 years old\n* Patient with neuromuscular scoliosis or progressive scoliosis resistant to conservative treatment\n* Patient with an indication of first-line surgery without graft\n* Patient with low skeletal maturity (Risser test = 0 and triradiate growth cartilages still open)\n* Signing of the consent by the holder (s) of parental authority and the investigator\n* Affiliated patient to a health service or entitled patient\n\nExclusion Criteria:\n\n* Patient with a history of spinal surgery\n* Patient weighing more than 30 kg and with progressive scoliosis other than neuromuscular\n* Patient with contra-indication to Nemost device, that is to say:\n\n * Inflammation or acute Infection, local or systemic,\n * Allergy or intolerance titanium or polyetheretherketone,\n * Pathology or poor bone quality might compromise the attachment of the device,\n * Nonreducible Scoliosis,\n * Skin Substance insufficient to cover the wound,\n * Pathological Obesity,\n * Fracture and / or spinal tumor,\n * Patient whose behavior presents a risk of failure for the device.'}, 'identificationModule': {'nctId': 'NCT02266667', 'acronym': 'NEMOST', 'briefTitle': 'Surgical Treatment of Progressive Scoliosis With "NEMOST" Growing Rod', 'organization': {'class': 'OTHER', 'fullName': 'Assistance Publique - Hôpitaux de Paris'}, 'officialTitle': 'Evaluation of the Efficiency of Nemost Growing Spine Device Associated With Physiotherapy in the Surgical Treatment of Progressive Scoliosis of the Child', 'orgStudyIdInfo': {'id': 'P140301'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Progressive scoliosis', 'description': 'Children with progressive scoliosis', 'interventionNames': ['Device: 1 NEMOST rod :unilateral vertebral-pelvic implantation']}, {'type': 'EXPERIMENTAL', 'label': 'Neuromuscular scoliosis', 'description': 'Children with neuromuscular scoliosis', 'interventionNames': ['Device: 2 NEMOST rods : bilateral vertebral-pelvic implantation']}], 'interventions': [{'name': '2 NEMOST rods : bilateral vertebral-pelvic implantation', 'type': 'DEVICE', 'description': 'Implantation of two NEMOST rods (bilateral vertebral-pelvic implantation)', 'armGroupLabels': ['Neuromuscular scoliosis']}, {'name': '1 NEMOST rod :unilateral vertebral-pelvic implantation', 'type': 'DEVICE', 'description': 'Implantation of one NEMOST rod (unilateral vertebral-pelvic implantation)', 'armGroupLabels': ['Progressive scoliosis']}]}, 'contactsLocationsModule': {'locations': [{'zip': '75015', 'city': 'Paris', 'country': 'France', 'facility': 'Hospital Necker Enfants Malades', 'geoPoint': {'lat': 48.85341, 'lon': 2.3488}}], 'overallOfficials': [{'name': 'Nejib KHOURI, MD, PhD', 'role': 'STUDY_DIRECTOR', 'affiliation': 'Hospital Necker Enfants Malades'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Assistance Publique - Hôpitaux de Paris', 'class': 'OTHER'}, 'collaborators': [{'name': 'Company EUROS', 'class': 'UNKNOWN'}, {'name': 'URC-CIC Paris Descartes Necker Cochin', 'class': 'OTHER'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
