Idys™ TLIF 3DTi Post Market Clinical Follow-up
- Conditions
- Degenerative Disc DiseaseGrade 1 Spondylolisthesis
- Registration Number
- NCT04584619
- Lead Sponsor
- Clariance
- Brief Summary
The aim of this observational post-marketing study is to provide additional information on the safety and effectiveness of Idys™ TLIF 3DTi at up to 24 months post transforaminal lumbar fusion in usual surgical practice.
- Detailed Description
The primary endpoint is to evaluate the effectiveness of the Idys™ TLIF (Transforaminal Lumbar Interbody Fusion) 3DTi (Porous Titanium additive manufacturing) by measuring the evolution of the rate of fusion during the postoperative period.
The secondary endpoints are to analyze the safety and the patient's benefit of the Idys™ TLIF 3DTi by evaluating several point of view:
* The adverse events related to the surgery;
* The functional improvement between preoperative state and the different follow-up time points using the Oswestry Disability Index (ODI);
* The improvement of back pain between preoperative state and the different follow-up time points using the Visual Analog Scale (VAS) (legs and back);
* The evolution of several radiologic lumbar parameters to assess the correction and its stability.

- Primary Outcome Measures
Name Time Method Evolution of the Fusion rate 6 months, 12 months, 24 months postoperatively Evolution of the radiological assessment of bony fusion at 3 different time point
- Secondary Outcome Measures
Name Time Method Evolution of the Patient Pain Preoperatively and then 6 weeks, 6 months, 12 months and 24 months postoperatively Assessment, at different time points, of the pain using Visual Analogue Scale (range 0 to 10 with higher scores meaning a worse outcome)
Radiologic Outcomes - Stability of the Idys TLIF 3DTi Device 6 weeks, 6 months, 12 months and 24 months postoperatively Measurement ,on x-rays at different time points, of the anterior position of the Idys TLIF 3DTi device
Radiologic Outcomes - Evolution of the lordosis angles (degree) Preoperatively and then 6 weeks, 6 months, 12 months and 24 months postoperatively Measurements, on x-rays at different time points, of the lordosis angle at pathological / implanted level and of the global lordosis angle between L1/S1
Adverse events Up to 24 months postoperatively To quantify and describe adverse events
Evolution of the Patient Disability Preoperatively and then 6 weeks, 6 months, 12 months and 24 months postoperatively Assessment, at different time points, of the disability using Oswestry Disability Index score (range 0 to 100 with zero corresponding to no disability and 100 corresponding to the maximum disability possible)
Radiologic Outcomes - Evolution of the Intervertebral Height (mm) Preoperatively and then 6 weeks, 6 months, 12 months and 24 months postoperatively Measurements, on x-rays at different time points, of the anterior and the posterior inter-vertebral height.
