Brief summary

Previous clinical study carried out on cancer patients at IOR Spine Surgery (approved in October 2014). The carbon device is indicated in patients suffering from vertebral tumors who need stabilization and will then carry out radiotherapy, because carbon has a practically zero level of interference with ionizing radiation. Carbon also allows for better visualization of the implants on MRI/CT and X-ray. There are no studies in the literature analyzing the use of carbon fiber devices in lumbar degenerative pathologies. 118 patients suffering from degenerative spinal pathology requiring 1 or 2 levels of lumbar or lumbosacral fusion will be valutated.

Design outcomes

Primary

MeasureTime frameDescription
Fusion ratethrough study completion, an average of 1 yearFusion rate after 12 months as demonstrated by computed tomography scan (CT scan). The CT scan will be evaluated by Brantigan scale.

Secondary

MeasureTime frameDescription
Classification system of surgical complications specific for spineat baseline (day 0)rate of intra-operative complications evaluated by SAVES classification system specific for spine
Visual Analogue Scaleat baseline (day 0)A Visual Analogue Scale (VAS) is one of the pain rating scales used for the first time in 1921 by Hayes and Patterson. It is often used in epidemiologic and clinical research to measure the intensity or frequency of various symptoms.
Oswestry Disability Indexat baseline (day 0)The Oswestry Disability Index (ODI) is a self-administered and validated questionnaire in Italian which aims to evaluate disabilities in subjects suffering from low back pain in both the acute and chronic phases.
EuroQoL-5Dat baseline (day 0)EQ-5D is a standardised measure of health-related quality of life developed by the EuroQol Group to provide a simple, generic questionnaire for use in clinical and economic appraisal and population health surveys. EQ-5D assesses health status in terms of five dimensions of health and is considered a 'generic' questionnaire because these dimensions are not specific to any one patient group or health condition
Short Form-12at baseline (day 0)The SF-12 is composed of 12 items (derived from the 36 of the original SF-36 questionnaire) which produce two measures relating to two different aspects of health: physical health and mental health. The SF-12 is made up of 4 scales (physical functioning, role and physical health, role and emotional state, mental health) measured by 2 items each and 4 scales each measured by one item (physical pain, vitality, social activities and general health).
