We sought to assess correlational relationship between mental health and outcomes following lateral lumbar interbody fusion (LLIF). Patients who had undergone LLIF were identified. Patients with indications for surgery including infection, trauma, or malignancy were excluded. Patient-reported outcomes (PROs) included short-form (SF)-12 Mental Component Score (MCS)/Patient Health Questionnaire (PHQ)-9/Patient-Reported Outcomes Measurement Information System−Physical Function (PROMIS-PF)/12-Item Short-Form Physical Component Score (SF-12 PCS)/Visual Analog Scale (VAS) back and leg pain/Oswestry Disability Index (ODI) and were collected preoperatively and at several postoperative time points extending to 1 year. Pearson correlation tests were used to compare the 12-item Short Form Mental Component Score (SF-12 MCS) and PHQ-9 with the other PROs. We included 124 patients. SF-12 MCS positively correlated with PROMIS-PF at 6 months (r = 0.466) and SF-12 PCS preoperatively (r = 0.287) and at 6 months (r = 0.419) (P ≤ 0.041, all). SF-12 MCS negatively correlated with VAS back preoperatively (r = −0.315), at 12 weeks (r = −0.414), and at 6 months (r = −0.746); VAS leg at 12 weeks (r = −0.378); and ODI preoperatively (r = −0.580) (P ≤ 0.023, all). PHQ-9 negatively correlated with PROMIS-PF at all periods except 12 weeks (range: r = −0.357 to −0.566, P ≤ 0.017, all) and SF-12 PCS preoperatively, at 6 weeks, and at 6 months (range: r = −0.363 to −0.562, P ≤ 0.022, all). PHQ-9 positively correlated with VAS back at all periods before 1-year (range: r = 0.415–0.690, P ≤ 0.001, all), VAS leg at 12-weeks (r = 0.467) and 6-months (r = 0.402) (P ≤ 0.028, both), and ODI at all periods except 6-months (range: r = 0.413–0.637, P ≤ 0.008, all). Better mental health scores correlated with superior physical function, pain, and disability scores when measured by both SF-12 MCS and PHQ-9. PHQ-9 more consistently reported significant correlation to all outcomes measured when compared to SF-12 MCS. [ABSTRACT FROM AUTHOR]

We aim to compare perioperative/postoperative clinical outcomes between minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and anterior lumbar interbody fusion (ALIF) in patients presenting for revision surgery. A retrospective database was reviewed for procedures between November 2005 and December 2021. Revision MIS-TLIF/ALIFs were included, whereas primary fusions or diagnosis of infection/malignancy/trauma were excluded. Patients were grouped into MIS-TLIF/ALIF cohorts. Preoperatively/postoperatively collected patient-reported outcome measures (PROMs) included visual analog scale back/leg score, Oswestry Disability Index, Patient-Reported Outcome Measurement Information System–Physical Function (PROMIS-PF), and Short-Form 12-Item Survey Mental/Physical Composite Scores. A total of 164 patients were eligible, with 84 patients in the MIS-TLIF cohort. The presence of degenerative spondylolisthesis and central stenosis, narcotic consumption on postoperative day 0/1, and postoperative urinary retention rates was greater in the MIS-TLIF cohort (P ≤ 0.036, all). Preoperative PROMs between cohorts did not significantly differ. Significantly favorable postoperative PROM scores were shown in the MIS-TLIF cohort with PROMIS-PF at 12 weeks/6 months (P ≤ 0.033, all). Most patients in both cohorts achieved overall minimum clinically important difference for visual analog scale back/leg score, Oswestry Disability Index, Short-Form 12-Item Survey Physical Composite Score, and PROMIS-PF. No differences were noted between cohorts within rates of MCID achievement. Patients undergoing revision fusion via MIS-TLIF or ALIF reported similar 1-year postoperative mean outcomes and rates of meaningful clinical achievement for physical function, mental health, disability, and back/leg pain. However, patients undergoing revision MIS-TLIF reported improved physical function at 12 weeks and 6 months. Perioperatively, patients undergoing revision MIS-TLIF were noted to consume significantly greater quantities of narcotics. [ABSTRACT FROM AUTHOR]

To compare patient-reported outcomes (PROMs), satisfaction, and minimum clinically important difference (MCID) achievement following minimally invasive transforaminal lumbar interbody fusion stratified by preoperative disability. Minimally invasive transforaminal lumbar interbody fusions were grouped by preoperative Oswestry Disability Index (ODI) score: ODI <41 or ODI ≥41. PROMs administered pre/postoperatively included Patient-Reported Outcomes Measurement Information System physical function (PROMIS-PF), visual analog scale (VAS) back/leg, ODI, and 12-Item Short-Form Physical Composite Score (SF-12 PCS)/12-Item Short-Form Mental Composite Score (SF-12 MCS). Satisfaction scores were collected for VAS back/leg and ODI. Coarsened exact match controlled for differences between cohorts. T tests compared mean PROMs and postoperative improvement/satisfaction between cohorts. Simple logistic regression compared MCID achievement. After coarsened exact matching, there were 118 patients in the ODI ≤41 and 377 patients in the ODI >41 cohort. The ODI >41 cohort saw greater postoperative inpatient VAS pain score and narcotic consumption on days 0/1 (P < 0.018, all). PROMs differed between cohorts: PROMIS-PF, SF-12 PCS, ODI, VAS back/leg at all postoperative time points and SF-12 MCS at 6 weeks/12 weeks/6 months/1 year (P < 0.045, all). Patients in the ODI >41 cohort demonstrated greater proportion achieving MCID for ODI at all postoperative time points and for SF-12 MCS 6-week/12-week/6-month/1-year (P < 0.040, all). The ODI ≤41 cohort demonstrated greater MCID achievement for overall PROMIS-PF and SF-12 PCS 6 months (P < 0.047, all). Postoperative satisfaction was greater in the ODI ≤41 cohort for VAS leg 6 weeks/12 weeks, VAS back 6 weeks/12 weeks, and ODI all postoperative time points (P < 0.048, all). Preoperative disability associated with worse postoperative PROMs and patient satisfaction for disability, back/leg pain at multiple time points. MCID achievement rates across cohorts were similar for most PROMs at most postoperative time points. Patients with severe disability may have unrealistic expectations for surgical benefits, influencing corresponding postoperative satisfaction. [ABSTRACT FROM AUTHOR]

We sought to assess differences in patient-reported outcome measures (PROMs) between patients who do and do not follow up for 2 years after lumbar fusion. Primary, elective, single-level anterior lumbar interbody fusion, lateral lumbar interbody fusion, or transforaminal lumbar interbody fusion procedures were identified. Patients were grouped by 2-year PROM follow-up completion. Mean and delta PROM scores for visual analog scale (VAS) back and leg, Oswestry Disability Index (ODI), short-form (SF)-12 Physical Composite Score (PCS), and Mental Composite Score (MCS) were computed for both groups preoperatively and postoperatively. Minimum clinically important difference (MCID) achievement was determined for PROM scores using established threshold values. Linear and logistic regression assessed mean and ΔPROM scores as predictors of 2-year follow-up completion and compared MCID achievement between groups, respectively. We included 316 lumbar fusion patients. PROM scores were more favorable for complete follow-up patients for 6-month VAS back (P = 0.003), 6-month and 1-year ODI (P ≤ 0.027, both), and 6-week and 6-month SF-12 PCS (P ≤ 0.015, both). Six-month VAS back (P = 0.007); 6-month and 1-year ODI (P ≤ 0.028, both); 6-week, 6-month, and 1-year SF-12 PCS (P ≤ 0.041, all); and 6-week SF-12 MCS (P ≤ 0.028, both) significantly predicted 2-year follow-up. ΔPROMs significantly differed between groups at 1 year for ΔVAS leg (P = 0.029), ΔODI (P = 0.013), and ΔSF-12 MCS (P = 0.004). One-year ΔVAS leg (P = 0.035), ΔODI (P = 0.011), and ΔSF-12 MCS (P = 0.003) significantly predicted follow-up. MCID achievement for ΔPROMs significantly differed between groups for 6-week VAS leg (P = 0.035), overall ODI (P = 0.034), and SF-12 PCS from 12 weeks through 1 year (P ≤ 0.011, all) and overall (P < 0.001). Patients with full follow-up demonstrated significantly more favorable outcome scores and improvement in pain, disability, and physical function at several postoperative time points.
