INTRODUCTION AND RATIONALE The vertebral arthrodesis is one of the surgical procedures most used for the treatment of deformities, trauma and degenerative diseases with instability of the spine (Rajaee et al., 2012; Yoshihara and Yoneoka, 2015).\n\n Using bone grafts and tools, such as metal rods and screws, this procedure creates a fusion between two or more adjacent vertebrae, in order to stabilize the spine.\n\n The success of fusion, intended as the neo-formation of trabecular bone radiographically detectable, may depend on the characteristics of the bone graft used and its properties as well as the surgical technique used. In the absence of autologous bone the biological process that leads to bone regeneration is characterized by three critical elements: the osteogenic potential, the osteoinductive factors, the osteoconductive scaffold. The ideal bone substitute possesses all three of these properties, combined with excellent compatibility and biological safety (Ludwig et al., 2000; Park et al., 2013).\n\n The local autologous bone harvested from the iliac crest has been and is still considered the "gold standard" in the treatment of spinal fusion. However, contraindications and potential complications associated with the use of autologous bone are well known (Dimar et al., 2009; Gruskay et al., 2014; Kim et al., 2009; Miyazaki et al., 2009). In order to overcome these limitations, several alternatives have been developed, clinically tested and are today available on the market: growth factors (BMPs) (Carragee et al., 2011; Kannan et al., 2015), allogenic bone or heterologous ( Gupta et al., 2015; Park et al., 2013), demineralized bone matrix (DBM) and synthetic ceramic materials to name a few (Abdullah et al., 2011; Fischer et al., 2013; Hsu et al., 2012) . Despite all of these materials have been extensively studied (Abdullah et al., 2011; Alsaleh et al., 2012; Hsu et al., 2012; Miyazaki et al., 2009) the available data are often uneven in quality, type of study, assessments performed and conclusions reached (Hsu et al., 2012; Kannan et al., 2015; Miyazaki et al., 2009).\n\n The ceramic bone substitutes of synthetic origin (Nickoli and Hsu, 2014), such as collagen, tricalcium phosphate (TCP) (Dai and Jiang, 2008), calcium phosphate (CaP), calcium sulphate (CaS) and hydroxyapatite (HA), have been designed and developed as osteoconductive scaffolds with characteristics and properties very similar to those of human bone, able to support the regeneration and bone remodeling, and go into slow resorption (Alsaleh et al. , 2012; Gao et al., 2014; Hsu et al., 2012; Kaiser et al., 2014; Kho and Chen, 2008; Korovessis et al., 2005; Lee et al., 2009; Zhou and Lee, 2011) .\n\n Fin-Ceramica Faenza SpA is a company engaged in the development of innovative solutions in the field of bone regeneration, and one of the latest solutions in the field of bone substitutes proposes the use of hydroxyapatite-based ceramic composites, biomaterials biomimetic new generation (Blackbeard et al., 2013; Zhou and Lee, 2011). Among these biomaterials, SintLife is a bone substitute consisting of Mg-HA crystals nano (sintered at body temperature). pre-clinical and preliminary clinical data show Sintlife the safety of the product and support the ability to use it as a bone substitute for spinal fusion (Brodano Barbanti et al., 2015; Brodano et al., 2014; Manfrini et al., 2013).\n2. IDENTIFICATION AND DESCRIPTION OF MEDICAL DEVICE SintLife is an implantable medical device, not active, with bone substitute function.\n\n SintLife features reabsorbtion cell-mediated. SintLife is a bone substitute, in paste form, consisting of physiological saline (percentage to 46%) and nanocrystals of magnesium-substituted hydroxyapatite (Mg-HA). The Mg2 + ions are introduced within the crystalline cell of HA in the same position and percentage found in the human bone mineral phase. E \'was shown that the presence of Mg2 + deforms the structure of the HAS crystalline cell by making it unstable and biologically active, thus promoting bone formation, remodeling, and a rapid resorption mediated by the cells of the material. In addition, the Mg-HA actively interacts with the water molecules to quickly capture key proteins involved in osteogenesis.\n\n SintLife interacts with the cells that form bone and promotes the deposition of new bone tissue. Thanks to its specific chemical composition and biomimetics, the nanostructure and the surface properties, it is reabsorbed and remodeled by the action mobile phone in a physiologically appropriate time (6-18 months), remaining at the application site for the duration of growth and of maturation of new bone.\n\n During the remodeling phase, one can observe the resorbing activity of osteoclasts to work around the particles of the material, until a complete bone regeneration (5). SintLife is classified as a Class III medical device, is CE marked and complies with current European legislation on medical devices (EC Directive 93/42 / EC amended 2007/47 / EC).\n3. PURPOSE, OBJECTIVES AND EVALUATION This pilot study is to evaluate the potential effectiveness of bone substitute SintLife within the spinal surgery in spinal stabilization applications for degenerative diseases.\n\n In particular, the investigators aim to evaluate:\n * the ability of bone regeneration / molding, defined as the presence of trabecular bone continuous bridge and absence of radiolucent lines, verified by diagnostic imaging (CT) and evaluated by means of in accordance with the scale Brantingan\n * the patient\'s state of health, through the comparison of the functional-symptom pattern between pre- and post-operative, verified by the scores Oswestry Disability Index (ODI), Visual Analogue Scale (VAS) and EuroQol (EQ-5D);\n * the safety of the medical device, through the impact of any adverse events, complications, unexpected reactions, accidents.\n4. STUDY DESIGN\n\n4.1. Study characteristics This collection of clinical data is set up as post-market pilot study. It will be included in the study all consecutive patients who require spinal fusion surgery, in accordance with the inclusion and exclusion criteria as voluntary and after signing the informed consent. Patients will be treated and followed postoperatively according to normal clinical practice, surgical and therapeutic in place at the Rizzoli Orthopaedic Institute of Bologna.\n\nThe total duration of data collection is 36 months:\n\n* the stage of patient enrollment is 18 months from the date of approval of the study by the Ethics Committee of the center;\n* the phase of post-operative monitoring is 18 months, with planned at 6, 12 and 18 months follow-up (± 15 days before scheduled date).\n\nIn relation to the literature up to now produced, it is considered advisable to provide a post-operative control at 18 months since the chemical composition and biomimetic hydroxyapatite-magnesium shows remodeling and resorption, in a physiologically time comprised between 6 and 18 months, as well as for other reported in Section 4.\n\n18 months is therefore the appropriate follow up to verify the medium term biomaterial behavior.\n\nAll data will be collected in a systematic, timely and uniform in a specific report form (SRD) paper.\n\n4.2. Treatment directions Patients will be treated for degenerative diseases of the spine, such as lumbar stenosis, spondylolysis and spondylolisthesis, degenerative disc disease.\n\nThe fusion technique used will be the posterolateral arthrodesis, of one or more vertebral levels included in the lumbosacral (L1-S1), obtained by means of screws and bars, together with a preparation of the transverse processes treated with bone substitute in order to Sintlife obtain new bone formation and then spinal fusion. It also provided the ability to associate interbody posterolateral arthrodesis with the use of cage.\n\n4.3. Visits plan During each visit (pre-operative, intra-operative, post-operative and follow-up) will be the responsibility of the surgeon to fill in the specific section in gathering data of every patient card.\n\nThe activities for each visit will be carried out as described below and as shown in the flow chart of visits (paragraph 2):\n\n* preoperative examination (pre-op) - signing the informed consent, assessment of the criteria for inclusion - exclusion, recording demographic data and medical history, the SEA assessment and ODI;\n* intervention - surgical report, TC, reports of potential adverse events intraoperative or immediate postoperative;\n* follow-up visit at 6 months after surgery - report of any adverse events, the SEA assessment, ODI, EQ-5D;\n* follow-up visit at 12 months after surgery - report of any adverse events, the SEA assessment, ODI, EQ-5D, TC;\n* follow-up visit at 18 months after surgery - report of any adverse events, the SEA assessment, ODI, EQ-5D, TC.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\nPatients who have provided consent to the processing of personal data;\n\n* Patients over the age of 18;\n* Patients who require posterolateral fusion of lumbosacral tract (L1- S1);\n* Patients suffering from traumatic and degenerative diseases of the spine, such as lumbar stenosis, spondylolysis and spondylolisthesis, degenerative disc disease;\n* Patients who agree to participate in the program of visits required by the Protocol.\n\nExclusion Criteria:\n\nPatients affected by:\n\n* systemic or localized infection\n* inflammatory or autoimmune disease\n* hypercalcemia\n* coagulation disorders\n* metabolic disorders\n* insulin dependent diabetes\n* alterations or complications of thyroid function\n* allergy to calcium phosphate\n* declared allergies to medications and / or medical device\n* tumor diseases and / or infectious diseases of the spine\n* active neoplasia\n* Patients who abuse of alcohol or drugs\n* Patients in the alleged pregnancy or confirmed\n* Patients on medication that causes abnormal bone regeneration (eg chemotherapy)\n* Already operated patients (revision surgery)'}, 'identificationModule': {'nctId': 'NCT03407560', 'briefTitle': 'Use of the Bone Substitute SintLife® in Vertebral Arthrodesis Procedures.
