Outcome Analysis for Minimally Invasive Spine Surgery and Navigation

Study Purpose

Prospective/Retrospective data analysis, chart reviews and clinical outcomes of minimally invasive spine surgery

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational
Eligible Ages	N/A and Over
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Patients with different spinal fusion procedures (including AxiaLIF (axial lumbar interbody fusion), TLIF (transforaminal lumbar interbody fusion), ELIF (extreme lateral interbody fusion), PCF (posterior cervical fusion), and ACDF (anterior discectomy and fusion)) using Silicate-Substituted Calcium Phosphate (Actifuse®, Baxter, Deerfield, IL) as a bone graft substitute.

Exclusion Criteria:

- Utilization of any other bone extenders in addition to Si-CaP as a bone graft substitute.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT01751841
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

STUDY RATIONALE AND PRIMARY OBJECTIVE/HYPOTHESIS To assess the clinical and radiographic outcome of spinal fusion procedures using Silicate-Substituted Calcium Phosphate (Si-CaP), a newer-generation of synthetic ceramics designed to maximize osteoinduction and osteoconduction. STUDY DESIGN Retrospective Study. PURPOSE OF THE STUDY Providing compelling evidence for the efficacy of Si-CaP in terms of resulting in satisfactory fusion. SUMMARY OF METHODS A prospectively collected database will be reviewed retrospectively, to retrieve data of 200 patients who have undergone different spinal fusion procedures using Silicate-Substituted Calcium Phosphate (Si-CaP). An average follow up duration of at least 12 months will be considered. Clinical outcomes will be assessed using the visual analog scale (VAS), Oswestry Disability Index (ODI), and Neck Disability Index (NDI). Pre-operative scores will be compared to the latest follow-up scores. A board certified Neuro-radiologist will assess the fusion rate. Fusion will be determined by the presence of bony bridging on 2 consecutive sections in at least 2 planes on computed tomographic imaging. SECONDARY ENDPOINTS AND EXPECTED RESULTS The purpose of this study is to evaluate the level of clinical and radiographic improvement in patients implanted with Silicate-Substituted Calcium Phosphate (Si-CaP) as a bone graft substitute material for spinal fusions. More comprehensive long term studies will be able to provide compelling evidence for the efficacy of Si-CaP in terms of resulting in satisfactory fusion. They can more strongly support the previously published data implying that Si-CaP can be utilized as an alternative to autogenous bone graft in spinal arthrodesis procedures.
