Sagittal Balance Through Ages

France2,000 participantsStarted 2020-01-02

Plain-language summary

The parameters of the sagittal balance of the cervical, thoracic and lumbar spine vary according to the types of spino-pelvic organization (types 1-4 according to Roussouly). These parameters have been described as a function of age in previous scientific work without taking into account the pelvic anatomy (pelvic incidence and spino-pelvic organization). This work, carried out within the framework of a round table of the French Society of Spinal Surgery (SFCR), would make it possible to provide a more detailed repository of existing radiographic parameters.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion criteria: * Minor or major subject aged 5 to 100 * Subject having carried out a telecolonne or EOS type X-ray for spinal balance (low back pain, sciatica, cervico-brachial neuralgia, inequality of length of the lower limbs) in spinal surgery consultation * Subject not having expressed its opposition, after information, to the re-use of its data for the purposes of this research. Exclusion criteria: * Subject with surgical history, fractures, osteoporotic packing, vertebral deformation (scoliosis, kyphosis, spondylolisthesis grades 2-5), vertebral osteolysis (spondylodiscitis, tumor or metastasis). * Subject who expressed his opposition to participate in the study * Subject under guardianship or curatorship * Subject under judicial protection

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.
