Abstract
Preoperative lower extremity neurologic deficits may affect outcomes in adult spinal deformity surgery.
To evaluate the impact of preoperative motor deficits on perioperative outcomes, complications, and patient-reported outcomes.
Retrospective analysis of a prospective multicenter study.
ASD patients undergoing surgery between 2009–2018.
Perioperative morbidity, complications, reoperation, and 2-year PROMs (ODI, SF-36 PF, SRS-22r).
Multivariable regression controlling for demographic and surgical variables.
Among 1,290 patients, 25% had preoperative motor deficits. These were associated with longer operative time (β=17.3, p=0.044), higher rates of new deficits (OR=1.9, p=0.018), major complications (OR=1.6, p=0.006), worse ODI (β=4.5, p=0.003), and worse SF-36 PF (β=-2.0, p=0.018). 52.4% recovered motor function by 6 weeks, but recovery did not correlate with 2-year outcomes.
Preoperative motor deficits are associated with worse perioperative and long-term outcomes. Early intervention and patient counseling are critical.
