Clinical Features and Surgical Outcomes of Lower Lumbar Osteoporotic Vertebral Collapse with Symptomatic Stenosis: A Surgical Strategy from a Multicenter Case Series.

When the clinical outcomes were compared according to the collapse grades, no difference in either the postoperative JOA scores or the LKA was observed between the different grades ( Table 3 ); however, the revision rate was considerably higher for the grade 4 group (40.0%) than that for other groups, although the difference did not reach statistical significance ( p =0.066).
