Post-trauma Lumbar Vertebral Body Reconstruction Using Expandable Cages

27 participantsStarted 2010-01-02

Plain-language summary

INTRODUCTION The expandable cage technology is not new, but several questions remain under-studied. Among them, there are the sagittal balance, the subsidence and the adjacent disc degeneration. Moreover, assessment of the correction and kyphosis regardless of the physiological angles can possibly lead to calculation bias. The objective of this study was to assess the extent to which the functional outcomes were correlated to the quality of the reduction, within a homogeneous series of lumbar vertebral body reconstruction with expandable cages for trauma. MATERIAL AND METHODS Twenty-seven patients with a mean follow-up of 3.9 years were retrospectively analyzed. The Oswestry Disability Index (ODI) was the main outcome and its association with other variables was sought. The local kyphosis and the regional traumatic angle using Stagnara's physiological angles were measured. The lumbar lordosis (LL) was compared to the Pelvic Incidence (PI). The subsidence of the cage and the adjacent disc degeneration (using the UCLA grading score) were quantified. Bone quality was assessed through the Hounsfield Unit of the vertebral body.

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.
