The impact of fixed segment length on the surgical outcomes of single-segment lumbar burst fractures: shorter segments are more prone to the formation of local stable osteophytes: a retrospective observational study

After a 2-year follow-up, the short-segment fixation group demonstrated a similar intervertebral height loss rate and intervertebral disc vacuum sign incidence compared to the long-segment fixation group, but a higher rate of stable osteophyte formation.
