Plain-language summary
This study is designed to collect safety and efficacy data on patients who plan to undergo a single-level total joint replacement of the lumbar spine using the MOTUS device (MOTUS Total Joint Replacement procedure) to demonstrate noninferiority to lumbar interbody fusion with respect to composite endpoints.

Inclusion criteria
. Male or female, age 21-80 (inclusive) with at least 3 years of life expectancy;
. The subject has a primary diagnosis of symptomatic lumbar degeneration with or without foraminal or recess stenosis of the lumbar spine at a single level from L1/L2 to L5/S1 confirmed by subject history and radiographic imaging (CT, MRI, X-rays) with no more than a Grade 1 (\<25% translation) spondylolisthesis. Symptomatic lumbar degeneration that may be associated with a co-morbid condition such as:
. Herniated nucleus pulposus;
. Scarring/thickening of the ligamentum flavum, annulus fibrosus, or facet joint capsule;
. Facet joint degeneration/osteophyte formation;
. Spondylosis (defined by the presence of osteophytes);
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.
. Lumbar stenosis defined by spinal cord or nerve root compression;
Exclusion criteria
. More than one vertebral level requiring treatment with instrumentation;
. Previous instrumented surgery (i.e.: anterior disc replacement, spinal fusion, interspinous device, etc.) at the index lumbar level or an adjacent level;
. Degenerative or lytic spondylolisthesis greater than Grade 1 (25% translation) associated with congenital (e.g. dysplastic) pars defects;
. Rotatory scoliosis (\>10 degrees) at the index level;
. Congenital bony and/or spinal cord abnormalities at the level to be treated such as conjoined nerve roots that would otherwise prevent placement of the device without generating nerve damage or skeletal malformations such as kyphotic vertebra that may be better suited for a different course of treatment (e.g. spinal fusion);
. Subcaudal defect, disrupting the integrity of the pedicle that presents undue risk of device subsidence or migration due to compromised bone quality/density;
. Clinically compromised vertebral bodies at the index level due to current or past trauma, e.g., by the radiographic appearance of the fracture callus, malunion or nonunion;
. Disrupted anterior longitudinal ligament at the index level;
