RESUMO
PURPOSE: To evaluate the effect of baseline back pain severity on PROMIS mental health outcomes following minimally invasive lumbar decompression (LD). METHODS: Patients undergoing elective, primary, single-level LD were retrospectively reviewed from a prospective single spine surgeon registry. Perioperative characteristics, demographics, and the following patient-reported outcomes (PROs) were extracted: Oswestry Disability Index (ODI)/Patient-Health Questionnaire-9 /PROMIS-Physical Function/Anxiety/Pain Interference/Sleep Disturbance (PROMIS-PF/A/PI/SD). Two cohorts were created: preoperative VAS-B < 7 and VAS-B ≥ 7. Change in PROs (ΔPROs) from baseline to six weeks/final follow-up were determined. Average patient follow-up was 13.4 ± 8.8 months. Minimal clinically important difference (MCID) achievement rates were calculated and compared through multivariable logistic regression. Postoperative scores and ΔPROs, were compared with multivariable linear regression while all other data was compared between groups with inferential statistics. RESULTS: Altogether, 347 patients were included, with 190 in the VAS-B < 7 group. VAS-B ≥ 7 reported worse outcomes preoperatively (p ≤ 0.013, all). At six weeks, VAS-B ≥ 7 reported worse VAS-B (p = 0.017), with no other significant differences. At final follow-up, patients with worse VAS-B reported worse ODI (p = 0.040) and VAS-B while all other PROs were similar (p ≥ 0.078, all). VAS-B ≥ 7 experienced greater 6-week improvements in VAS-B/ODI/PROMIS-PI/PROMIS-SD (p ≤ 0.009, all), greater VAS-B/ODI/PROMIS-SD improvement by final follow-up (p ≤ 0.009, all) and greater MCID achievement in ODI/VAS-B (p ≤ 0.027). CONCLUSION: Patients with worse baseline back pain report inferior baseline scores that converge with those with milder preoperative back pain by 6 weeks after LD and reported greater 6-week improvements in disability, pain interference, and sleep disturbance by 6 weeks, and greater improvements in disability and sleep disturbance by final follow-up.
RESUMO
PURPOSE: To determine the prognostic value of preoperative Veterans RAND-12 (VR-12) Physical Composite Score (PCS) scores on postoperative clinical outcomes in patients undergoing lateral lumbar interbody fusion (LLIF). METHODS: LLIF patients were separated into 2 cohorts based on preoperative VR-12 PCS scores: VR-12 PCS < 30 (lesser physical function) and VR-12 PCS ≥ 30 (greater physical function). Patient-reported outcome measures (PROMs) of VR-12 PCS, VR-12 Mental Composite Score (MCS), Short Form-12 (SF-12) PCS, SF-12 MCS, Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), Patient Health Questionnaire-9 (PHQ-9), Visual Analog Scale (VAS) Back Pain (VAS-BP), VAS Leg Pain (VAS-LP), and Oswestry Disability Index (ODI) were collected at preoperative and up to 2-year postoperative time points. Mean postoperative follow-up time was 16.69 ± 8.53 months. Minimum clinically important difference (MCID) achievement was determined by comparing ∆PROM to previously established thresholds. RESULTS: Seventy-eight patients were included, with 38 patients with lesser preoperative physical function scores. Patients with lesser physical function reported significantly inferior preoperative PROM scores in all domains, except for SF-12 MCS and VAS-LP. At the 6-week postoperative time point, patients with lesser physical function reported significantly inferior VR-12 PCS, VR-12 MCS, SF-12 PCS, PROMIS-PF, and PHQ-9. At the final postoperative time point, patients with lesser physical function reported significantly inferior VR-12 PCS, VR-12 MCS, PROMIS-PF, PHQ-9, and ODI. Magnitude of 6-week postoperative improvement was significantly higher in the lesser physical function cohort for VR-12 PCS. CONCLUSION: Patients undergoing LLIF with worse baseline VR-12 PCS scores reported inferior postoperative physical function, mental health, and disability outcomes. At the final postoperative follow-up, magnitude of postoperative improvement and MCID achievement did not significantly differ. Baseline VR-12 PCS scores may indicate inferior postoperative clinical outcomes in physical function, mental health, and disability in patients undergoing LLIF; however, baseline VR-12 PCS does not limit the magnitude of postoperative improvement.

Traumatic brain injury (TBI) is a leading cause of long-term disability in the United States. Even in comparatively mild injuries, cognitive and behavioral symptoms can persist for years, and there are currently no established strategies for mitigating symptoms in chronic injury. A key feature of TBI-induced damage in acute and chronic injury is disruption of metabolic pathways. As neurotransmission, and therefore cognition, are highly dependent on the supply of energy, we hypothesized that modulating metabolic activity could help restore behavioral performance even when treatment was initiated weeks after TBI. We treated rats with pioglitazone, a FDA-approved drug for diabetes, beginning 46â¯days after lateral fluid percussion injury and tested working memory performance in the radial arm maze (RAM) after 14â¯days of treatment. Pioglitazone treated TBI rats performed significantly better in the RAM test than untreated TBI rats, and similarly to control animals. While hexokinase activity in hippocampus was increased by pioglitazone treatment, there was no upregulation of either the neuronal glucose transporter or hexokinase enzyme expression. Expression of glial markers GFAP and Iba-1 were also not influenced by pioglitazone treatment. These studies suggest that targeting brain metabolism, in particular hippocampal metabolism, may be effective in alleviating cognitive symptoms in chronic TBI.

BACKGROUND: Patients with lumbar spinal pathology often suffer from anxiety and sleep disturbance, but correlations between anxiety and sleep disturbance and other patient-reported outcome measures (PROMs) before and after surgical intervention have not been explored. The purpose of this study is to analyze the correlations between patient-reported anxiety, sleep disturbance, and PROMs before and after lumbar decompression. METHODS: All patients undergoing elective, primary, lumbar decompression were retrospectively queried from a prospectively-maintained single spine surgeon database. Demographic and perioperative data and pre- and postoperative PROMs were extracted. Patient-Reported Outcome Measure Information System (PROMIS)-Anxiety, PROMIS-Sleep Disturbance (SD), PROMIS-Physical Function (PF), 9-Item Patient Health Questionnaire (PHQ-9), Visual Analog Scale (VAS)-Back, VAS-Leg, Oswestry Disability Index (ODI) were obtained preoperatively and through two years postoperatively. Pearson's correlation coefficients were calculated between PROMIS-Anxiety, PROMIS-SD, and the other PROMs of interest. RESULTS: PROMIS-Anxiety was positively correlated with PROMIS-SD (range: r = 0.473-0.828, p ≤ 0.006, all), PHQ-9 (range: r = 0.613--0.890, p ≤ 0.006, all), VAS-Back (range: r = -0.410-0.798, p ≤ 0.039, all), and ODI (range: r = 0.503-0.732, p ≤ 0.033, all) at all timepoints. PROMIS-Anxiety was negatively correlated with PROMIS-PF through 1 year postoperatively (range: r = -0.323- -0.729p ≤ 0.033, all). PROMIS-Anxiety was positively correlated to VAS-Leg at preoperative, 6-week, 12-week, and 2-year postoperative timepoints (range: r = 0.333--0.707, p ≤ 0.022, all). PROMIS-SD was positively correlated with PHQ-9 (range: r = 0.600-0.836), VASBack (range: r = 0.383-0.734), VAS-Leg (range: r = 0.399-0.811), and ODI (range: r = 0.404-0.812) at all timepoints (p ≤ 0.031, all). PROMIS-SD was negatively correlated with PROMIS-PF at all timepoints (range: r = -0.339-0.665, p ≤ 0.035, all). CONCLUSION: Patient-reported anxiety and sleep disturbance are significantly correlated with depressive burden, back pain, disability, and physical function, before and after lumbar decompression. Future studies should aim to determine the directionality of the associations and test interventions to improve health-related quality of life following lumbar decompression.
RESUMO
The influence of Charlson Comorbidity Index (CCI) burden on Patient-Reported Outcomes Measurement Information System (PROMIS) outcomes following lumbar decompression (LD) is limited. The objective of this study is to evaluate CCI burden impact on PROMIS outcomes. Retrospective review of elective LD excluding revision or surgeries for infectious, malignant, or traumatic reasons. Demographics and PROMIS scores collected preoperatively and postoperatively up to 2 years included: PROMIS-Physical Function (PF)/Sleep Disturbance (SD)/Pain Interference (PI)/Anxiety (A), VR-12 Physical/Mental Health Composite scores (VR-12 PCS/MCS)/Oswestry Disability Index (ODI). Patients were divided into two groups based on their preoperative CCI score <3 (mild) or ≥4 (moderate to severe). Descriptive statistical analysis and MCID achievement rate calculations were conducted. A total of 182 patients were included: 93 CCI < 3 and 88 CCI ≥ 4. No significant differences were reported across preoperative PROMIS/legacy PROMs or final follow-up (p > 0.05, all). At 6-weeks, VR-12 PCS and ΔPROM scores indicated improved physician function in the CCI < 3 group (p = 0.020 and p = 0.040, respectively). Significant PROMIS-A ΔPROM score at final post-op was noted for CCI < 3 group (p = 0.026). MCID achievement demonstrated no significant differences for PROMIS outcomes and legacy PROMs. Results demonstrated that PROMIS outcomes were not impacted by a greater baseline comorbidity burden. At 6-weeks, the physical function scores were improved for the lower CCI group, and at final reported less anxiety. Our data suggests that comorbidity burden has a limited effect on PROMIS and legacy outcomes in patients undergoing LD.

STUDY DESIGN: This is a retrospective review. OBJECTIVE: To examine the effect of preoperative motor weakness on clinical outcomes in patients undergoing cervical disk replacement (CDR). SUMMARY OF BACKGROUND DATA: Studies examining the effect of preoperative motor weakness on postoperative clinical outcomes in CDR are limited. METHODS: Patient cohorts were based on documented upper-extremity motor weakness on physical exam versus no motor weakness. Demographics, perioperative characteristics, and preoperative patient-reported outcome measures (PROMs) were compared using univariate inferential statistics. PROMs consisted of Visual Analog Pain Scale-Neck (VAS-N), Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), VAS-Arm (VAS-A), 12-Item Short Form (SF-12) Physical Component Score (PCS), Oswestry Neck Disability Index (NDI), and SF-12 Mental Component Score (MCS). Postoperative PROMs were collected at the 6-week, 12-week, 6-month, and final follow-up up to 1-yeartime points, and intercohort minimum clinically important difference (MCID) achievement was compared through multivariable linear logistic regression adjusting for significant differences in preoperative characteristics. RESULTS: A total of 118 patients formed cohorts based on documented upper-extremity weakness (n=73) versus no weakness (n=45). The average time to postoperative follow-up was 9.7±7.0 mo. The differences in insurance type between the 2 cohorts were significant (P<0.042). Perioperative diagnosis of foraminal stenosis was significantly more common in the motor weakness cohort (P<0.013). There were no differences in reported PROMs between cohorts. Patients with motor weakness reported significant MCID achievement for PROMIS-PF at 6-/12-weeks (P<0.012, P<0.041 respectively), SF-12 PCS at 6-months (P<0.042), VAS-N at final follow-up (P<0.021), and NDI at final follow-up (P<0.013). CONCLUSIONS: CDR patients with preoperative muscle weakness achieved MCID across several PROMs compared with patients without muscle weakness. Patients with motor weakness reported greater improvement in mental health, pain, and disability as early as 6 weeks and up to 1 year after CDR. This information serves to inform physicians that motor weakness may not indicate a negative overall outcome.
RESUMO
BACKGROUND AND OBJECTIVES: Severe facet arthropathy is generally a contraindication to undergoing cervical disc replacement (CDR) due to associated instability and potentially limited improvement in neck pain caused by arthropathy. This study evaluates the influence of facet arthropathy on radiographic/early clinical outcomes after CDR. METHODS: One/two-level CDR patients from a single surgeon's prospectively maintained database created 2 cohorts based on facet arthropathy: grade 0-1 or 2-3 (milder/moderate arthropathy). Patient-reported outcome measures for neck disability, neck/arm pain, depressive burden, mental/physical health/function were obtained preoperatively and through final follow-up (average follow-up: 8.5 ± 6.5 months). Preoperative/postoperative radiographs measured segmental lordosis and C2-C7/segmental range of motion (ROM) and determined facet grade for each operative level. Demographic differences, perioperative variables, baseline patient-reported outcomes, and intercohort differences/changes for postoperative patient-reported/radiographic outcomes were determined. RESULTS: Of 161 patients, 100 were in the milder arthropathy group. There were no differences in baseline patient-reported outcomes. Patients with moderate arthropathy reported superior 6-week 12-Item Veterans Rand Mental/Physical Composite Scores (P ≤ .047, all). By final follow-up, moderate patients reported better 12-Item Veterans Rand Mental/Physical Composite Scores/Patient-Reported Outcome Measurement Information System-Physical Function/Patient-Health Questionnaire-9 (P ≤ .049, all). Cohorts reported similar improvements in all patient-reported outcomes by 6 weeks/final follow-up. Those with more severe facet arthropathy had significantly shorter preoperative disc heights (P < .001). Accounting for baseline disc height differences, by final follow-up, moderate patients had lower segmental ROM (P = .036). There were no significant differences in radiographic measurement changes (P ≥ .264, all). CONCLUSION: Postoperatively, patients with moderate facet arthropathy reported lower depressive burden, better mental health/physical function, and lower segmental ROM. However, this did not translate to inferior short-term clinical outcomes. Further study should be conducted on the relationship between clinical/radiographic outcomes in CDR patients with facet arthropathy.
RESUMO
STUDY DESIGN: Retrospective Review. OBJECTIVE: Evaluate the influence of the 12-Item veterans Rand (VR-12) physical component score (PCS) on patient-reported outcome measures (PROMs) in an outpatient lumbar decompression (LD) cohort. SUMMARY OF BACKGROUND DATA: The influence of baseline VR-12 PCS on postoperative clinical outcomes has not been evaluated in patients undergoing outpatient LD. METHODS: Patients undergoing primary, elective, 1/2-level outpatient LD with baseline VR-12 PCS scores were retrospectively identified from a prospectively maintained single-surgeon database. Cohorts were preoperative VR-12 PCS<30 and VR-12 PCS≥30. Patient/perioperative characteristics and preoperative/postoperative 6-week/final follow-up (FF) PROMs were collected. Physical health PROMs included the VR-12 PCS, 12-Item Short Form (SF-12) PCS, patient-reported outcome measure information system-physical function (PROMIS-PF), visual analog scale (VAS)-back/leg, and Oswestry disability index (ODI). Mental health PROMs included the VR-12/SF-12 mental component score (MCS) and the patient-health questionnaire-9 (PHQ-9). Average FF was 13.8±8.9 months postoperatively. PROM improvements at 6 weeks/FF and minimal clinically important difference (MCID) achievement rates were determined. χ2 analysis and the Student's t tests compared demographics, perioperative data, and preoperative PROMs. Multivariate linear/logistic regression compared postoperative PROMs, PROM improvements, and MCID achievement rates. RESULTS: Six weeks postoperatively, VR-12 PCS<30 reported worse baseline PROMs (P≤0.042, all) and worse scores except VR-12/SF-12 MCS (P≤0.043, all). Compared with VR-12 PCS≥30, VR-12 PCS<30 had worse FF VR-12 PCS, SF-12 PCS/MCS, PROMIS-PF, PHQ-9, and VAS-Back (P≤0.033, all). VR-12 PCS<30 experienced greater 6-week improvements in VR-12/SF-12 PCS, PHQ-9, VAS-Back, and ODI (P≤0.039, all). VR-12 PCS<30 had greater FF improvements in VR-12/SF-12 PCS, PHQ-9, and ODI (P≤0.001, all) and greater overall MCID achievement in VR-12 PCS/MCS, SF-12 PCS, PHQ-9, and ODI (P≤0.033, all). CONCLUSIONS: VR-12 PCS<30 patients-reported worse baseline/postoperative mental/physical health scores. However, they reported greater improvements in physical function, depressive burden, back pain, and disability by 6 weeks and FF and experienced greater MCID achievement for physical functioning, mental health, and disability scores.
RESUMO
STUDY DESIGN: Retrospective Review. OBJECTIVE: To assess the impact of preoperative pain and disability on patient-reported outcome measures (PROMs) following minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) for degenerative spondylolisthesis. SUMMARY OF BACKGROUND DATA: Varying preoperative symptom severity in lumbar fusion patients alters perceptions of surgical success. METHODS: Degenerative spondylolisthesis patients undergoing elective, primary, single-level MI-TLIF were stratified by preoperative symptom severity: Mild (VAS-B<7/ODI<50), Moderate (VAS-B≥7/ODI<50 or VAS-B<7/ODI≥50), and Severe (VAS-B≥7/ODI≥50). PROMs, Patient-reported Outcomes Measurement Information System-Physical Function (PROMIS-PF), ODI, VAS-B, VAS-Leg (VAS-L), and 9-item Patient Health Questionnaire (PHQ-9) were compared at baseline, 6 weeks, and final follow-up (µ=16.3±8.8 mo). Postoperative PROMs, magnitudes of improvement, and minimal clinically important difference (MCID) achievement rates were compared between cohorts through multivariable regression. RESULTS: A total of 177 patients were included. Acute postoperative pain and narcotic consumption were highest in the severe cohort (P≤0.003). All preoperative PROMs worsened from mild to severe cohorts (P<0.001). All PROMs continued to be significantly different between cohorts at 6 weeks and final follow-up, with the worst scores in the Severe cohort (P≤0.003). At 6 weeks, all cohorts improved in ODI, VAS-B, VAS-L, and PHQ-9 (P≤0.003), with the Moderate cohort also improving in PROMIS-PF (P=0.017). All Cohorts improved across PROMs at the final follow-up (P≤0.044). Magnitudes of improvement in ODI, VAS-B, and PHQ-9 increased with worsening preoperative symptom severity (P≤0.042). The Moderate and Severe cohorts demonstrated higher MCID achievement in ODI, VAS-B, and PHQ-9 rates than the Mild cohort. CONCLUSIONS: Despite preoperative pain and disability severity, patients undergoing MI-TLIF for degenerative spondylolisthesis report significant improvement in physical function, pain, disability, and mental health postoperatively. Patients with increasing symptom severity continued to report worse severity postoperatively compared with those with milder symptoms preoperatively but were more likely to report larger improvements and achieve clinically meaningful improvement in disability, pain, and mental health.
RESUMO
BACKGROUND: Little research has been done to evaluate the prognostic value of short-term postoperative patient-reported outcomes (PROs) on long-term PROs following lumbar decompression (LD). We evaluated the prognostic value of short-term PROs on long-term PROs through 2 years after LD. METHODS: A single spine surgeon database was retrospectively queried for patients undergoing primary LD with 6-week postoperative PROs reported. The demographics, perioperative traits, and preoperative, 6-month, 1-year, and 2-year PROs were recorded. The PROs included the visual analog scale (VAS) for back pain, VAS for leg pain, PRO measure information system for physical function (PROMIS-PF), and Oswestry disability index. Two-step multivariate linear regression was performed to determine the predictive value of 6-week PROs for the 6-month, 1-year, and 2-year PROs. RESULTS: A total of 277 patients were included. The 6-week Oswestry disability index, VAS for leg pain, and 9-item patient health questionnaire (PHQ-9) are all positive predictors for their respective outcomes at 6 months. Additionally, the 6-week PROMIS-PF was a negative predictor of the 6-month PHQ-9. The 6-week PROMIS-PF positively predicted the PROMIS-PF through 1 year, and the PHQ-9 was a positive predictor of the PHQ-9 at 1 and 2 years postoperatively. CONCLUSIONS: The 6-week postoperative PROs are predictive of the same outcomes at 6 months, the PROMIS-PF is predictive through 1 year, and the PHQ-9 is predictive through 2 years. Determining the predictive value of early postoperative PROs can be helpful in understanding the likely postoperative trajectory following LD and informing patient expectations.

No study has examined the prognostic value of the Veterans RAND-12 (VR-12) Mental Component Score (MCS) on postoperative outcomes in minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) patients. This study examines the effect of preoperative VR-12 MCS on postoperative patient-reported outcome measures (PROMs) in MIS-TLIF patients. Patients were separated into 2 cohorts: VR-12 MCS < 50 and VR-12 MCS ≥ 50. PROMs of VR-12 MCS/Physical Component Score (PCS), Short Form-12 (SF-12) MCS/PCS, Patient-Reported Outcomes Measurement Information System-Physical Function (PROMIS-PF), Patient Health Questionnaire-9 (PHQ-9), Visual Analog Scale (VAS) Back/Leg Pain (VAS-BP/LP), and Oswestry Disability Index (ODI) were collected.Of 329 patients, 151 were in the VR-12 MCS < 50 cohort. The VR-12 MCS < 50 cohort reported significantly inferior scores in all PROMs preoperatively, significantly inferior VR-12 MCS, SF-12 MCS, PROMIS-PF, PHQ-9, and ODI scores at 6-weeks postoperatively, and significantly inferior scores in all PROMs, except for VAS-BP at final follow-up. Magnitude of 6-week postoperative improvement was significantly greater in the VR-12 MCS < 50 cohort for VR-12 MCS, SF-12 MCS, and PHQ-9. Magnitude of final postoperative improvement was significantly greater in the VR-12 MCS < 50 cohort for VR-12 MCS, SF-12 MCS/PCS, and PHQ-9. MCID achievement rates were significantly greater in the VR-12 MCS < 50 cohort for VR-12 MCS, SF-12 MCS, and PHQ-9. MIS-TLIF patients with lesser preoperative VR-12 MCS reported inferior postoperative outcomes in mental health, physical function, pain, and disability. However, patients with inferior preoperative mental health reported greater rates of clinically meaningful improvement in mental health. Inferior preoperative mental health does not limit postoperative improvement in patients undergoing MIS-TLIF.

This study measures the impact of preoperative motor weakness (MW) on Patient-Reported Outcome Measures (PROMs) in lateral lumbar interbody fusion (LLIF) patients. Retrospectively-sourced data from a prospectively-maintained, single-surgeon database created two cohorts of LLIF patients: patients with/without documented MW. Demographics/perioperative characteristics/PROMs were collected preoperatively and at six-weeks/final follow-up (FF). Studied outcomes were Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), 12-Item Short Form (SF-12) Physical/Mental Component Score (PCS/MCS), Patient Health Questionnaire (PHQ-9), Visual Analog Scale Back/Leg Pain (VAS-BP/LP), and Oswestry Disability Index (ODI). Multivariable linear/logistic regression calculated/compared intercohort minimum clinically important difference (MCID). Mean postoperative follow-up time was 11.5 ± 7.52 months. In total, 214 LLIF patients from December 2010 to May 2023 were included, with 149 having documented MW. In Table 1, self-reported gender was significant between cohorts (p < 0.025). Other significant demographic characteristics were smoker status (p < 0.002), diabetes (p < 0.016), and CCI score (p < 0.011). Table 2 shows notably significant perioperative characteristics: spinal pathology (degenerative spondylolisthesis/foraminal stenosis/herniated nucleus pulposus) (p < 0.005, all), estimated blood loss/length of stay/postoperative day (POD)-zero narcotic consumption (p < 0.001, all). Table 3 outcomes/MCID achievement percentages demonstrated insignificant intercohort differences besides a weakly significant FF ODI score (p < 0.036). MW, a frequently reported symptom in spine surgery, is poorly studied in LLIF patients. Thus, this study evaluates MW impact on PROMs and notes no significant differences. However, one exception regarding FF disability scores was recorded. MW did not affect MCID achievement for our patient population. Therefore, the preliminary findings suggest preoperative MW imparts minimal influence on PROMs/MCID in LLIF patients.

OBJECTIVE: To evaluate the effect of Veterans RAND 12-item health survey mental composite score (VR-12 MCS) on postoperative patient-reported outcome measures (PROMs) after undergoing lateral lumbar interbody fusion. METHODS: Retrospective data from a single-surgeon database created 2 cohorts: patients with VR-12 MCS ≥ 50 or VR-12 MCS < 50. Preoperative, 6-week, and final follow-up (FF)- PROMs including VR-12 MCS/physical composite score (PCS), 12-item Short Form health survey (SF-12) MCS/PCS, Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), Patient Health Questionnaire-9 (PHQ-9), visual analogue scale (VAS)-back/leg pain (VAS-BP/LP), and Oswestry Disability Index (ODI) were collected. ∆6-week and ∆FF-PROMs were calculated. Minimal clinically important difference (MCID) achievement rates were determined from established cutoffs from the literature. For intercohort comparison, chi-square analysis was used for categorical variables, and Student t-test for continuous variables. RESULTS: Seventy-nine patients were included; 25 were in VR-12 MCS < 50. Mean postoperative follow-up time was 17.12 ± 8.43 months. The VR-12 MCS < 50 cohort had worse VR-12 PCS, SF-12 MCS, PROMIS-PF, PHQ-9, VAS-BP, and ODI scores preoperatively (p ≤ 0.014, all), worse VR-12 MCS/PCS, SF-12 MCS, PROMIS-PF, PHQ-9, and ODI scores at 6-week postoperatively (p ≤ 0.039, all), and worse VR-12 MCS, SF-12 MCS, PROMIS-PF, PHQ-9, VAS-BP, VAS-LP, and ODI scores at FF (p ≤ 0.046, all). The VR-12 MCS < 50 cohort showed greater improvement in VR-12 MCS and SF-12 MCS scores at 6 weeks and FF (p ≤ 0.005, all). The VR-12 MCS < 50 cohort experienced greater MCID achievement for VR-12 MCS, SF-12 MCS, and PHQ-9 (p ≤ 0.006, all). CONCLUSION: VR-12 MCS < 50 yielded worse mental health, physical function, pain and disability postoperatively, yet reported greater improvements in magnitude and MCID achievement for mental health.
RESUMO
OBJECTIVE: To evaluate preoperative disability's influence on patient-reported outcomes (PROs) following surgery for degenerative spondylolisthesis (DS). METHODS: DS patients who underwent surgical intervention were retrospectively identified from a single-surgeon spine registry. Cohorts based on Oswestry Disability Index (ODI) < 41 (milder disability) and ≥ 41 (severe disability) were created. Demographic differences were accounted for with 1:1 propensity score matching. For the matched sample, perioperative and PRO data were additionally collected. PROs assessed included mental health, physical function, pain, and disability. Pre- and up to 2-year postoperative PROs were utilized. Average time to final follow-up was 15.7 ± 8.8 months. Improvements in PROs and minimal clinically important difference (MCID) rates were calculated. Continuous variables were compared through Student t-test and categorical variables were compared through chi-square tests. RESULTS: Altogether, 214 patients were included with 77 in the milder disability group. The severe disability group had worse postoperative day (POD) 1 pain scores and longer hospital stays (p ≤ 0.038, both). The severe disability group reported worse outcomes pre- and postoperatively (p < 0.011, all), but had greater average improvement in 12-item Short Form health survey mental composite score (SF-12 MCS), 9-Item Patient Health Questionnaire (PHQ-9), visual analogue scale (VAS)-back, and ODI by 6 weeks (p ≤ 0.037, all) and PHQ-9, VAS-back and ODI by final follow-up (p ≤ 0.015, all). The severe disability cohort was more likely to achieve MCID for SF-12 MCS, PHQ-9, and ODI (p ≤ 0.003, all). CONCLUSION: Patients with greater baseline disability report higher POD 1 pain and discharge later than patients with milder disability. While these patients report inferior physical/mental health before and after surgery, they report greater improvements in mental health and disability postoperatively.
RESUMO
STUDY DESIGN: Retrospective review. OBJECTIVE: To examine the effect of baseline Veterans RAND-12 (VR-12) Mental Composite Score (MCS) on clinical outcomes in patients undergoing cervical disk replacement (CDR) for herniated disk. BACKGROUND: Few studies in spine surgery have evaluated the impact of preoperative VR-12 MCS on postoperative outcomes in patients undergoing CDR. METHODS: Patients undergoing CDR for herniated disk were separated into 2 cohorts based on the VR-12 MCS standardized mean: VR-12 MCS<50 (worse mental health) and VR-12 MCS≥50 (better mental health). Patient-reported outcome measures of VR-12 MCS, VR-12 Physical Composite Score, Short Form-12 (SF-12) MCS, SF-12 Physical Composite Score, Patient-Reported Outcomes Measurement Information System Physical Function, Patient Health Questionnaire-9 (PHQ-9), Visual Analog Scale (VAS) Neck Pain, VAS Arm Pain, and Neck Disability Index were collected at preoperative and up to 2-year postoperative time points. RESULTS: In all, 109 patients were identified, with 50 patients in the worse mental health cohort. The worse mental health cohort reported inferior patient-reported outcome measures in all domains at preoperative, 6-week postoperative, and final postoperative time points. For 6-week postoperative improvement, the worse mental health cohort reported greater improvement for VR-12 MCS, SF-12 MCS, and PHQ-9. For final postoperative improvement, the worse mental health cohort reported greater improvement in VR-12 MCS and SF-12 MCS. Minimum clinically important difference achievement rates were higher in the worse mental health cohort for VR-12 MCS, SF-12 MCS, and PHQ-9. CONCLUSION: Patients undergoing cervical disk replacement for herniated disk with worse baseline mental health reported inferior clinical outcomes in mental health, physical function, pain, and disability outcomes throughout the postoperative period. Patients with worse baseline mental health demonstrated greater clinically meaningful improvement in mental health. In cervical disk replacement patients, those with worse baseline mental health may report inferior postoperative clinical outcomes but experience greater rates of tangible improvement in mental health.

No study has evaluated the preoperative impact of Veterans RAND-12 Physical Composite Score (VR-12 PCS) on anterior lumbar interbody fusion (ALIF) patients. This study examines its influence on physical function, mental health, pain, and disability outcomes. Two cohorts of ALIF patients with preoperative VR-12 PCS scores were formed using a single-surgeon registry: VR-12 PCS < 30 and VR-12 PCS ≥ 30. Demographics, perioperative characteristics, and patient-reported outcome measures (PROMs) were collected. PROMs of VR-12 PCS/Mental Composite Score (MCS), Short Form-12 (SF-12) PCS/MCS, Patient-Reported Outcomes Measurement Information System-Physical Function (PROMIS-PF), Patient Health Questionnaire-9 (PHQ-9), Visual Analog Scale-Back/Leg Pain (VAS-BP/LP), and Oswestry Disability Index (ODI) were collected pre/postoperatively up to 2-years. Demographics, perioperative characteristics, and preoperative PROMs were compared. Intercohort postoperative 6-week/final PROMs and improvements were compared. Of 80 patients, there were 41 in the VR-12 PCS < 30 cohort. Besides VR-12 PCS, VR-12 PCS < 30 patients reported inferior preoperative VR-12 MCS/SF-12 PCS/PROMIS-PF/PHQ-9/ODI scores (p ≤ 0.003, all). At 6-weeks postoperatively, VR-12 PCS < 30 reported inferior VR-12 PCS/SF-12 PCS/PROMIS-PF/PHQ-9 (p ≤ 0.030, all). There was greater improvement up to 6-weeks postoperatively in VR-12 PCS < 30 for VR-12 PCS/MCS and SF-12 PCS (p ≤ 0.020, all). VR-12 PCS < 30 reported superior improvement by final follow-up in VR-12 PCS/SF-12 PCS/PHQ-9 (p ≤ 0.006, all). MCID achievement rates were higher in VR-12 PCS < 30 for PHQ-9 and ODI (p ≤ 0.013, both). VR-12 PCS < 30 patients reported inferior postoperative physical function, mental health, and disability, yet superior magnitude of improvement in physical function and mental health. Rates of clinically meaningful improvement for VR-12 PCS < 30 were greater in mental health and disability.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To assess the impact of preoperative symptom duration (PSD) on patient-reported outcome measures (PROMs) after minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) for degenerative spondylolisthesis (DSpond). BACKGROUND: A prolonged duration of preoperative symptoms may implicate inferior long-term outcomes postsurgery. Prior studies of lumbar fusion recipients are limited by the inclusion of heterogeneous populations. METHODS: A single-surgeon registry was retrospectively queried for privately insured patients who had undergone primary, elective, single-level MIS-TLIF for DSpond with a recorded symptom start date. Cohorts were formed by PSD: shorter duration (PSD <1 y) or greater duration (GD; PSD ≥1 y). PROMs evaluated included Patient-reported Outcomes Measurement Information System-Physical Function, Oswestry Disability Index, Visual Analog Scale-Back, Visual Analog Scale-Leg, and 9-item Patient Health Questionnaire. The magnitude of PROM (∆PROM) improvement from preoperative baseline to 6 weeks and final follow-up (∆PROM-FF) were compared between cohorts. Intercohort achievement rates of a minimum clinically important difference in each PROM were compared. RESULTS: A total of 133 patients included 85 patients with GD cohort. There were no significant differences in pre hoc demographics and perioperative characteristics between cohorts, as well as preoperative, 6-week, or final follow-up PROMs between cohorts. Both cohorts demonstrated significant improvement in all PROMs at 6 weeks and final follow-up ( P ≤ 0.049, all). There were no significant intercohort differences demonstrated in minimum clinically important difference achievement rates, ∆PROM-6W, or ∆PROM-FF in any PROM. CONCLUSIONS: Regardless of the symptom duration before MIS-TLIF for DSpond, patients demonstrate significant improvement in physical function, pain, disability, and mental health. Patients with a GD of preoperative symptoms did not report inferior scores in any PROM domain. Patients with a GD of preoperative symptoms did not suffer inferior rates of clinically meaningful improvement after surgical intervention. These findings should be considered when counseling patients before surgical intervention for DSpond.

STUDY DESIGN: Retrospective review. OBJECTIVE: To assess the impact of Body Mass Index (BMI) on patient-reported outcome measures (PROMs) after cervical disc replacement (CDR). BACKGROUND: BMI may affect PROMs after spine surgery. METHODS: Primary CDR recipients for herniated disc(s) with BMI <40 were retrospectively selected from a single-surgeon registry. Cohorts were divided into non-obese (BMI <30) and obese (BMI ≥30). Intercohort in-hospital complication rates were compared through independent samples t tests. Pre/postoperative PROMs were compared between cohorts through multivariable regression accounting for demographic differences. Final follow-up dates between patients averaged 11.8 ± 9.3 months. PROMs assessed included Patient-reported Outcomes Measurement Information System-Physical Function, Neck Disability Index, Visual Analog Scale-Neck, Visual Analog Scale-Arm, and the 9-item Patient Health Questionnaire. Improvements in PROMs were evaluated and compared at each follow-up within cohorts through paired t tests. The magnitude of improvement in PROMs from preoperative baseline at 6-week follow-up (∆PROM-6W) and final follow-up (∆PROM-FF) along with achievement rates of minimum clinically important differences were compared between cohorts through multivariable regression accounting for demographic differences. RESULTS: Of 153 patients, 53 patients were noted as obese. Demographic differences included age, prevalence of hypertension and diabetes, and comorbidity burden scores ( P ≤ 0.011, all). No significant variations in in-hospital complications were found. The non-obese cohort demonstrated improvements in all PROMs at 6 weeks and final follow-up periods ( P ≤ 0.005, all). The obese cohort demonstrated improvements in all postoperative PROMs besides 9-item Patient Health Questionnaire at 6 weeks ( P ≤ 0.015, all). After accounting for age and comorbidity variations, there were no significant intercohort differences in raw PROM scores, ∆PROM-6W, ∆PROM-FF, or minimum clinically important difference achievement rates. CONCLUSIONS: Regardless of BMI, patients experience significant improvements in physical function, disability, pain, and mental health after CDR for disc herniation. Patients with obesity do not suffer inferior patient-perceived outcomes after CDR. These findings may help surgeons counsel patients in the preoperative period.

STUDY DESIGN: Retrospective review. OBJECTIVE: To evaluate mental health influence on minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) patients. SUMMARY OF BACKGROUND DATA: Poor mental health has been postulated to indicate inferior patient perceptions of surgical outcomes in spine literature. Few studies have assessed mental health as a dynamic metric throughout the perioperative period. METHODS: A single-surgeon database was retrospectively searched for patients who underwent primary, elective MIS-TLIF for degenerative or isthmic spondylolisthesis. Summative depressive burden (SDB) was defined by the sum of preoperative and 6-week postoperative 9-item Patient Health Questionnaire (PHQ-9), with Lesser Burden (LB, SDB<10) and Greater Burden (GB, SDB≥10) cohorts. Patient-reported outcomes measures (PROMs) were compared preoperatively, at 6 weeks, and at final postoperative follow-up (11.4±10.9 mo), using Patient-Reported Outcomes Measurement Information System-Physical Function (PROMIS-PF), Oswestry disability index (ODI), visual analog scale-back (VAS-B), VAS-leg (VAS-L), and PHQ-9. Improvements at 6-week (∆PROM-6W), final follow-up (∆PROM-FF), and minimum clinically important difference (MCID) achievement were compared. RESULTS: The GB cohort consisted of 44 of 105 patients. Demographic variations included older age, higher Charlson comorbidity index, increased hypertension prevalence, and private insurance in the LB cohort (P≤0.018). The LB cohort demonstrated better baseline and 6-week PROMIS-PF/ODI/VAS-L (P≤0.032) and better final PROMIS-PF/ODI/VAS-L/PHQ-9 (P≤0.031). Both cohorts improved in all PROMs at 6 weeks and final follow-up (P≤0.029), except for PROMIS-PF at 6 weeks in the GB cohort. ∆PROM-6W, ∆PROM-FF, and MCID achievement rate for PHQ-9 were greater in the GB cohort (P≤0.001). CONCLUSION: On average, patients undergoing MIS-TLIF for degenerative or isthmic spondylolisthesis improved in all PROMs by final follow-up. Patients with GB suffered inferior perceptions of physical function, disability, and leg pain. MCID rates in mental health were higher for GB cohort. Surgeons are encouraged to adopt a compassionate understanding of depressive burden and educate the patient on possible consequential postoperative outcomes.
