Abstract

OBJECTIVE: The Lumbar Stiffness Disability Index (LSDI) assesses impact of lumbar stiffness on activities of daily living. We hypothesized that patientsdeformity.

METHODS: Patients completed the LSDI and Scoliosis Research Society 22 Questionnaire, Revised (SRS-22r) preoperatively and at 2 years postoperatively. The primary independent variable was patient age≥60. Multivariable regression analyses were used.

RESULTS: Analysis included 267 patients. Patients(51.3%) and ≥60 years old (48.7%) were evenly represented. In bivariable analysis, patients age≥60 (25.7 vs. 35.5, β -9.8, P < 0.0001), but a directionally smaller difference at 2 years (26.4 vs. 32.3, β -5.8, P = 0.0147). LSDI was associated with lower SRS-22r total score among both age groups at baseline and 2 years (all P < 0.0001); the association was stronger among patients age

CONCLUSIONS: Among patients with adult spinal deformity managed operatively, higher LSDI was associated with inferior SRS-22r total score and satisfaction at 2 years postoperatively. The association between increased LSDI and worse patient-reported outcome measures was greater among patients age≥60. Preoperative counseling is needed for patients agesatisfaction.
