Registered outcomes6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Cage Subsidence at 18 Months After Surgery | Postoperative predischarge imaging as the reference and 18 months after surgery; subsidence-related revision surgery assessed through 18 months. | Number of participants with interbody cage subsidence, defined as a decrease of more than 2 mm in intervertebral disc height at any operated level compared with the postoperative predischarge imaging reference. A participant with subsidence at one or more operated levels is counted once. Participants undergoing revision surgery for cage subsidence before the 18-month assessment are also counted as having the outcome. |
| Secondary | Change in Intervertebral Disc Height | 18 months after surgery. | Change in intervertebral disc height, measured in millimeters, from postoperative predischarge imaging to 18 months after surgery. |
| Secondary | Change in Intervertebral Foraminal Height | 18 months after surgery. | Change in intervertebral foraminal height, measured in millimeters, from postoperative predischarge imaging to 18 months after surgery. |
| Secondary | Change in Lumbar Lordosis at 18 Months | 18 months after surgery. | Change in lumbar lordosis, measured in degrees, from postoperative predischarge imaging to 18 months after surgery. |
| Secondary | Number of Participants With Pseudarthrosis | 18 months after surgery. | Number of participants with radiographic pseudarthrosis at one or more operated levels at 18 months after surgery. For this study, pseudarthrosis is defined as radiographic nonunion on CT, classified as Bridwell grade III (an intact graft with radiolucency at the superior or inferior graft-endplate interface) or grade IV (absent fusion with graft resorption or collapse). Each participant is counted once, regardless of the number of affected levels. |
| Secondary | Functional Improvement | Baseline and 18 months after surgery. | Change in the Oswestry Disability Index (ODI) score from baseline to 18 months after surgery. The ODI measures back-related disability, with scores ranging from 0 to 100 and higher scores indicating greater disability. Change is calculated as the 18-month score minus the baseline score; negative values indicate improvement. |
