About this study
Official title: LISA Post Market Clinical Follow-Up Study:Post Marketing Prospective Documentation of Clinical Outcomes (Post-operative, Safety and Performance) After Lumbar Dynamic Stabilization Surgery With LISA Implant
The study is a post-market surveillance study of the Lumbar Implant for Stiffness Augmentation (LISA), a medical device, which is used to treat low-back pain that accompanies degenerative lesions of grades II, III, and IV (Pfirrmann MRI classification). "Post-market" means the device (i.e. the LISA implant) being used in this study has already obtained CE certification and is commercially available for use in the European market.
The LISA device consists of 3 components: A PEEK interspinous spacer, a polyester band, and a titanium blocker. The spacer is positioned between two adjacent spinous processes, the band is belted around the spinous processes and through the spacer, and the blocker is used to lock the band inside the spacer.

Medical Device manufacturers conduct "post-market" clinical studies in order to continuously evaluate the product scientifically and to comply with legal and ethical obligations. With these studies, the long-term safety as well as performance of their medical devices are assessed.
This study, which is initiated and sponsored by BACKBONE (LISA designer, developer, manufacturer and marketer), aims to evaluate the long-term safety and performance of the LISA implant for the treatment of lumbar degenerative disease and to evaluate the treatment.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The study is a post-market surveillance study of the Lumbar Implant for Stiffness Augmentation (LISA), a medical device, which is used to treat low-back pain that accompanies degenerative lesions of grades II, III, and IV (Pfirrmann MRI classification). "Post-market" means the device (i.e. the LISA implant) being used in this study has already obtained CE certification and is commercially available for use in the European market.
The LISA device consists of 3 components: A PEEK interspinous spacer, a polyester band, and a titanium blocker. The spacer is positioned between two adjacent spinous processes, the band is belted around the spinous processes and through the spacer, and the blocker is used to lock the band inside the spacer.

How can a doctor refer a patient or contact the research team?
Contact Aurélie Affret (0033686114973, aat@backbone.pro), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
LISA implant survival rate 2 years after surgery defined as successful LISA implantation without reoperation, revision, or removal/ ODI change between pre-operative assessment and 2 years follow-up (FU)/ 1ary endpoint will also be evaluated at 1-year FU (time frame: 24-months post surgery; 12-months post surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
