The UK MHRA has issued two similar Medical Device Alerts (MDA) with the most recent MDA issued on 1st April 2020, stating that (1) MAGEC rods must not be implanted in the UK until further notice and (2) all patients already implanted with this device should be followed up as soon as is possible.\n\nAt the time of writing, hospitals across the world are facing incredible challenges in dealing with the COVID-19 pandemic. Due to this, virtually all planned clinic visits for MAGEC rod patients and X-ray appointments have been postponed to help reduce the risk of the virus spreading.\n\nRecent retrieval studies have shown that mechanical wear and corrosion of these rods is common, with a risk that the debris generated is released into surrounding tissue. This wear and corrosion is thought to be the primary cause of implant failures and the underlying implant factors leading to the issuing of FSNs and MDAs.\n\nWhilst titanium is known to be highly biocompatible, the baseline and toxic levels of this alloy in biological fluids are poorly understood. Additionally, a better understanding of blood titanium levels in patients with MAGEC rods may enable this to become a biomarker of wear and corrosion of the rods. This may help surgeons identify earlier those patients who may develop implant related problems.\n\nFurthermore, in the current COVID-19 environment, a blood test to measure titanium levels may be one of the most suitable ways in which to continue patient monitoring (and identify those at greatest risk of implant related issues), in the absence of regular clinic visits.\n\nPrevious work from the RNOH involved a similar study investigating patients with titanium hip implants.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Children being treated for early onset scoliosis.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients that have been treated with, and still have, a MAGEC rod.\n\nExclusion Criteria:\n\n* Patients that do not have a MAGEC rod implant.'}, 'identificationModule': {'nctId': 'NCT04337151', 'briefTitle': 'Blood Titanium Analysis of Patients With MAGEC Spine Rods in the COVID-19 Environment', 'organization': {'class': 'OTHER', 'fullName': 'Royal National Orthopaedic Hospital NHS Trust'}, 'officialTitle': 'Blood Titanium Analysis of Patients With MAGEC Spine Rods in the COVID-19 Environment', 'orgStudyIdInfo': {'id': 'RNOH MAGEC'}}, 'armsInterventionsModule': {'interventions': [{'name': 'MAGEC Spine Rod', 'type': 'DEVICE', 'description': 'Magnetically controlled growing spine rod used for the surgical treatment of scoliosis.'}, {'name': 'Titanium blood test', 'type': 'DIAGNOSTIC_TEST', 'description': 'A blood test captured to measure the level of titanium'}]}, 'contactsLocationsModule': {'locations': [{'zip': 'HA74LP', 'city': 'Stanmore', 'status': 'RECRUITING', 'country': 'United Kingdom', 'contacts': [{'name': 'Harry Hothi, PhD', 'role': 'CONTACT', 'email': 'harry.hothi@nhs.net', 'phone': '+44 (0) 20 8909 5847\u202c'}], 'facility': 'Royal National Orthopaedic Hospital', 'geoPoint': {'lat': 51.61667, 'lon': -0.31667}}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Royal National Orthopaedic Hospital NHS Trust', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Implant Science Fellow', 'investigatorFullName': 'Dr Harry Hothi', 'investigatorAffiliation': 'Royal National Orthopaedic Hospital NHS Trust'}}}}
