Analysis of Three-Dimensional Navigated Lateral Lumbar Interbody Fusion
Taiwan11 participantsStarted 2021-07-18
Plain-language summary
This observational study evaluates the clinical outcomes and procedural characteristics of navigation-assisted oblique lumbar interbody fusion (OLIF) in patients with lumbar degenerative disease. Between July 2021 and December 2021, adult patients undergoing OLIF with robotic or navigation assistance at Cheng Hsin General Hospital were included. Navigation systems were used to guide interbody cage placement and percutaneous pedicle screw insertion.
Information regarding operative time, intraoperative blood loss, radiation exposure to patients and operating room staff, and postoperative complications was collected. Clinical outcomes, including back and leg pain and lumbar function, were assessed during routine postoperative follow-up.
This study aims to describe the feasibility and short-term outcomes of navigation-assisted OLIF, including screw placement accuracy and early postoperative clinical improvement, and to provide additional clinical information regarding the use of navigation systems in minimally invasive lumbar fusion surgery.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Adult male and female patients aged 20 years or older with lumbar spine disease confirmed by clinical evaluation.
* Patients who are willing to undergo oblique lumbar interbody fusion (OLIF) via an anterior or oblique lumbar approach.
* Patients who have provided written informed consent in accordance with local regulatory requirements.
Exclusion Criteria:
* Patients who are currently participating in, or have participated within the past 6 months in, another clinical study involving an investigational procedure, device, or drug.
* Patients who, in the judgment of the principal investigator, have conditions that may impair their ability to provide written informed consent, such as psychiatric disorders or neurodegenerative diseases.
* Patients experiencing uncontrollable or unavoidable events, including but not limited to legally defined infectious diseases, pregnancy, severe accidental injury, or death.
* Patients who are unwilling or unable to comply with postoperative follow-up.
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.
