LISA Post Market Clinical Follow-Up Study: Documentation of Clinical Outcomes After Surgery With LISA Implant
Denmark, France, Germany136 participantsStarted 2019-04-17
Plain-language summary
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.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
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
Timeframe: 24-months post surgery; 12-months post surgery
