-
A prospective cohort study. ⋯ Changed LL after decompressive surgery for LSS was associated with improved ODI and physical function.
-
Retrospective observational cohort. ⋯ This study identifies duration of IOH during the first hour of surgery as a previously unrecognized modifiable risk associated with major complications for multi-level lumbar fusion surgery.
-
Retrospective cohort study. ⋯ This study demonstrates a significant and independent association between AAC and degeneration of the erector spinae and the psoas muscles in patients undergoing lumbar fusion. As both AAC and degeneration of paraspinal muscles impact postoperative outcomes negatively, preoperative assessment of AAC may aid in identifying patients at higher risk after lumbar surgery.
