“The extent of preoperative depression is an independent predictor of functional outcome after revision lumbar surgery for pseudarthrosis, recurrent stenosis and ASD,” the study concludes.
It compared the preoperative results of 150 patients’ score on a Zung Self-Reported Depression Scale to results showing improvement two years following revision neural decompression and instrumented fusion for ASD, psudarthrosis or same-level recurrent stnosis. Authors of the study conclude that, based on their results, future comparative studies should account for depression when assessing outcomes of revision lumbar surgery.
