TL;DR
The study found that while radiographic outcomes like intervertebral space height and foramen height differed among RIT grades, there were no significant differences in fusion rates or cage-related complications between the groups.

The study found that while radiographic outcomes like intervertebral space height and foramen height differed among RIT grades, there were no significant differences in fusion rates or cage-related complications between the groups.
This retrospective study analyzed 83 patients who underwent TLIF for lumbar degenerative disease, evaluating 151 fusion segments classified into three groups based on a novel relative intervertebral tension (RIT) grading standard. Radiographic outcomes at final follow-up showed significant differences: Group A had the smallest intervertebral space angle (ISA), while Group C had the largest. Group B maintained the highest intervertebral space height (ISH) and foramen height (IFH), with Group A having the lowest. Cage-related complications, including migration and subsidence, also showed no significant differences between groups.
