Abstract
BACKGROUND Veterans RAND 12-item (VR-12) physical component score (PCS) has been validated in both veteran and US citizen populations; however, its use for spine surgery populations has not been evaluated. This study aims to correlate the VR-12 PCS survey with legacy patient-reported outcome measures (PROMs) in patients undergoing minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). METHODS A prospective surgical database was retrospectively assessed for MIS TLIFs performed at 1 level from March 2015 to June 2019. Inclusion criteria were elective procedures for degenerative spinal pathology. Patients were excluded if they had surgery for metastatic, traumatic, or infectious etiologies or had incomplete preoperative 12-item Short Form (SF-12) PCS or Patient-Reported Outcomes Measurement Information System physical function (PROMIS-PF) survey. Additionally, patients with any incomplete VR-12 PCS surveys through 1 year were excluded. Demographics and perioperative characteristics were recorded. Mean postoperative PROM scores and score difference from preoperative baseline were calculated at each postoperative timepoint through 1 year. The relationship of VR-12-PCS with SF-12-PCS and PROMIS PF was evaluated with a Pearson's correlation coefficient and time-independent partial correlation. RESULTS A total of 59 patients underwent single-level MIS TLIFs. The cohort was 44.1% women with an average age of 53.8 years, and 52.5% were obese (body mass index ≥30 kg/m2). The VR-12 PCS, SF-12 PCS, and PROMIS PF surveys had significant improvements from baseline to the 6 month through 1 year postoperative timepoints (P ≤ 0.001, all). All timepoints revealed strong VR-12-PCS correlations with SF-12-PCS and PROMIS PF (all P ≤ 0.001). CONCLUSION VR-12 PCS, SF-12 PCS, and PROMIS PF scores all indicate statistically significant improvements in physical function for patients following MIS TLIF. VR-12 PCS was strongly correlated with the historically validated SF-12 PCS system as well as with the more recent PROMIS PF survey. Our observations give weight to utilizing the VR-12 PCS survey as a valid measure of physical function among patients undergoing MIS TLIF. CLINICAL RELEVANCE This study validates VR-12 PCS to measure physical function for TLIF patients. LEVEL OF EVIDENCE: 4

Spine Surgery Complications in the Ambulatory Surgical Center Setting: Systematic Review. Clin Spine Surg 2022; 35:118-126. [PMID: 34183543 DOI: 10.1097/bsd.0000000000001225] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Accepted: 06/01/2021] [Indexed: 11/26/2022]
Abstract
STUDY DESIGN This was a systematic review study. PURPOSE This study aims to review current literature to determine the rates of complications in relation to spine surgery in ambulatory surgery centers (ASC). BACKGROUND Recent improvements in anesthesia, surgical techniques, and technological advances have facilitated a rise in the use of ASC. Despite the benefits and lower costs associated with ASCs, there is inconsistent reporting of complication rates. METHODS This systematic review was completed utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Pertinent studies were identified through Embase and PubMed databases using the search string ((("ambulatory surgery center") AND "spine surgery") AND "complications"). Articles were excluded if they did not report outpatient surgery in an ASC, did not define complications, were in a language other than English, were non-human studies, or if the articles were classified as reviews, book chapters, single case reports, or small case series (≤10 patients). The primary outcome was the frequency of complications with respect to various categories. RESULTS Our query identified 150 articles. After filtering relevance by title, abstract, and full text, 22 articles were included. After accounting for 2 studies that were conducted on the same study sample, a total of 11,245 patients were analyzed in this study. The most recent study reported results from May 2019. While 5 studies did not list their surgical technique, studies reported techniques including open (6), minimally invasive surgery (2), endoscopic (4), microsurgery (1), and combined techniques (4). The following rates of complications were determined: cardiac 0.29% (3/1027), vascular 0.25% (18/7116), pulmonary 0.60% (11/1839), gastrointestinal 1.12% (2/179), musculoskeletal/spine/operative 0.59% (24/4053), urologic 0.80% (2/250), transient neurological 0.67% (31/4616), persistent neurological 0.61% (9/1479), pain related 0.57% (20/3479), and wound site 0.68% (28/4092). CONCLUSIONS After literature review, this is the first study to comprehensively analyze the current state of literature reporting on the complication profile of all ASC spine surgery procedures. The most common complications were gastrointestinal (1.12%) and the most infrequent were vascular (0.25%). Case reports varied significantly with regard to the type and rate of complications reported. This study provides complication profiles to assist surgeons in counseling patients on the most realistic expectations.

Preoperative Physical Function Association With Mental Health Improvement After Anterior Cervical Discectomy and Fusion. Clin Spine Surg 2021; 34:E559-E565. [PMID: 34224424 DOI: 10.1097/bsd.0000000000001232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Accepted: 06/01/2021] [Indexed: 11/25/2022]
Abstract
STUDY DESIGN This was a retrospective study. OBJECTIVE This study investigates the influence of physical function and their influence on postoperative depressive symptom scores as measured by Patient Health Questionnaire-9 (PHQ-9) among anterior cervical decompression and fusion (ACDF) patients. BACKGROUND While ACDF is one of the most commonly performed ambulatory surgeries, research is limited on the predictive value of Patient-Reported Outcomes Measurement Information System (PROMIS) scores and their influence on depressive symptoms as measured by the PHQ-9. METHODS A prospectively maintained surgical registry was retrospectively reviewed from March 2016 to January 2019. Inclusion criteria were primary or revision ACDF procedures. Patients were grouped by preoperative PROMIS score (≥35.0, <35.0), with higher scores indicating greater physical function. The χ2 and Student t tests assessed categorical and continuous variables (eg, demographics, perioperative, and postoperative values). A t test evaluated postoperative improvement in PROMIS Physical Function (PF) scores between subgroups among PROMIS PF scores and PHQ-9 score improvement at 6, 12 weeks, 6 months, and 1 year. Linear regression assessed preoperative PROMIS scores influence on PHQ-9 score improvement. RESULTS The 121 subject cohort was 61.2% male with an average age of 49.6±9.8 years. Compared with the PROMIS ≥35.0 group, the PROMIS <35.0 group also had larger improvement of PROMIS scores at 6 weeks. No significant difference in postoperative PHQ-9 improvement was observed between subgroups. There was a negative association between preoperative PROMIS scores and improvement in PROMIS scores at 6, 12 weeks, 6 months, and 1 year. There was a positive association between preoperative PROMIS scores and magnitude of 1-year PHQ-9 change. CONCLUSIONS Individuals with lower preoperative PROMIS PF scores had significantly higher PHQ-9 scores at 1 year. Patients with lower preoperative physical function, as evaluated by PROMIS PF scoring, had greater improvement of mental health at 1 year postoperatively. This suggests that many patients experience multidimensional health benefits after ACDF procedures.

Abstract
STUDY DESIGN Retrospective. OBJECTIVE Evaluate the association between comorbidity burden and reaching minimum clinically important difference (MCID) following lumbar decompression (LD). SUMMARY OF BACKGROUND DATA There is limited research on the influence of preoperative comorbidity burden on patient-reported outcome improvement following LD. METHODS A prospectively maintained surgical registry was retrospectively reviewed for eligible spine surgeries between 2015 and 2019. Inclusion criteria were primary, single, or multilevel LD. Patients were excluded for missing preoperative patient-reported outcome surveys. Stratification was based on Charlson Comorbidity Index (CCI) score: 0 points (no comorbidities), 1-2 points (low CCI), ≥3 points (high CCI). Demographics and perioperative characteristics were evaluated for differences. Linear regression assessed postoperative improvement for visual analogue scale (VAS) back, VAS leg, Oswestry disability index (ODI), Short Form-12 Physical Composite Score (SF-12 PCS), and Patient-Reported Outcomes Measurement Information System physical function (PROMIS-PF) scores through 1 year. Achievement rate of MCID was compared between groups and evaluated for significant predictors. RESULTS Three hundred fourteen patients were included (123 no comorbidities, 100 low CCI, 91 high CCI). Higher CCI patients were older, more likely to smoke, and have comorbid diseases (all P<0.001). Perioperative differences included increased operative time, levels decompressed, length of stay, and discharge day in the CCI≥3 group. No differences in the rate of achieving MCID for VAS back, VAS leg, and ODI. CCI≥3 subgroup had a lower rate of reaching MCID at 6 months for SF-12 PCS, at 6 weeks for PROMIS-PF, and the overall rate for both SF-12 PCS and PROMIS-PF (all P<0.05). Multilevel procedures was a predictor for MCID achievement for ODI. CONCLUSIONS Patients with increased comorbidities undergoing LD had an equivalent MCID achievement rate for pain and disability metrics through 1 year. High CCI patients did, however, have a lower rate of achieving MCID for their physical function surveys which suggests that comorbidity burden influences improvement in physical function following LD.

Abstract
BACKGROUND Research focused on postoperative outcomes among men and women undergoing minimally invasive lumbar decompression (MIS LD) spine surgery is sparse. This study aims to assess the influence of sex on postoperative patient-reported outcome measure (PROM) evaluations and achievement of a minimum clinically important difference (MCID). METHODS A prospectively maintained surgical database was retrospectively queried for patients undergoing primary or revision, single or multilevel LD procedures from 2011 to 2019. Patients with incomplete visual analog scale (VAS) leg or back surveys were excluded. Demographic and operative variables were recorded, and a chi-squared analysis or t tests were used to compare by sex. PROMs were evaluated from preoperative to postoperative time points. PROM score differences and postoperative improvement were evaluated between sexes by a t test. Achievement of MCID by sex was compared using chi-squared analysis. RESULTS The study cohort (n = 572) was 70% male (n = 398), had an average age of 47 years, and 42% were obese. Sexes differed in preoperative VAS leg, Oswestry Disability Index (ODI), and 12-item short form (SF-12)-physical composite score (PCS) scores (all P < .05) and in ODI at 6 and 12 weeks (P = .048; P = .001) and VAS back and leg scores at 6 months (P = .039; P = .019). Both sexes significantly improved (P < .050) all PROMs at all time points except for VAS back at 1 year for women and ODI at 6 weeks and 6 months for men. The only significant difference in achievement of MCID was for ODI at 6 months (P = .008). CONCLUSIONS Significant preoperative differences were observed among sexes with ODI, SF-12-PCS, and VAS leg scores. By 1 year, there were no significant sex differences for any PROM or for achievement of MCID. MIS LD has an equivalent role for both sexes in achieving MCID. LEVEL OF EVIDENCE 3. CLINICAL RELEVANCE Results demonstrate no sex difference in PROMs following LD.

Abstract
BACKGROUND There is a scarcity of research on the Charlson Comorbidity Index (CCI) and its influence on minimum clinically important difference (MCID) achievement after minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF). The objective of this study is to detail the association between the CCI and attaining MCID after MIS TLIF. METHODS A prospective surgical registry was retrospectively reviewed for spine surgeries between May 2015 and February 2019. Inclusion criteria were primary or revision, 1- or 2-level MIS TLIF procedures. Patients were stratified based on CCI score: 0 points (no comorbidities), 1-2 points (mild CCI), ≥3 points (moderate CCI). Preoperative, intraoperative, and postoperative variables were assessed by subgroup using appropriate statistical analysis. Subgroups were analyzed with linear regression or χ2 tests for continuous or categorical variables, respectively. Subgroup scores, improvement, and MCID achievement were assessed at postoperative timepoints (eg, 6 weeks, 12 weeks, 6 months, and 1 year) for back and leg pain, Oswestry Disability Index (ODI), SF-12 Physical Composite Score (PCS), and Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS PF). RESULTS A total of 171 patients were included (n = 51 [no comorbidities], n = 73 [mild CCI], and n = 47 [moderate CCI]). Higher CCI patients were older and more likely to be smokers, diabetic, arthritic, hypertensive, or have a malignancy history (P < 0.003). Preoperatively, ODI and PROMIS PF were the only patient-reported outcomes with a significant association by CCI group (P = 0.015 and 0.014). Back pain was the only measure that had a significant association with the CCI subgroup at 1 year for score (P = 0.002) or MCID (P = 0.028). CONCLUSIONS By 1 year, regardless of the number of comorbidities, a similar proportion of patients undergoing MIS TLIF were able to achieve MCID for visual analog scale leg, SF-12 PCS, and PROMIS PF. Patients with higher comorbidities are not likely to experience a significant difference in symptom improvement. Regardless of CCI score, MIS TLIF can have a significant benefit for patients.

Abstract
BACKGROUND Patient selection and analgesic techniques, such as the multimodal analgesic (MMA) protocol, aid in ambulatory surgical center (ASC) cervical spine surgery. The purpose of this case series is to characterize patients undergoing anterior cervical discectomy and fusion (ACDF) and total cervical disc replacement (CDR) in an ASC with an enhanced MMA protocol. METHODS A prospectively maintained registry was retrospectively reviewed for cervical surgeries between May 2013 and August 2019. Inclusion criteria included ASC patients who underwent single-level or multilevel CDR or ACDF using an MMA protocol. Baseline, intraoperative, and postoperative characteristics were recorded, including length of stay, visual analog scale pain scores, neck disability index, complications, and narcotics administered. RESULTS A total of 178 patients met inclusion criteria with 125 single-level, 52 two-level, and 1 three-level procedure. Of those patients, 127 underwent ACDF and 51 underwent CDR. The longest procedure was 95 minutes and the mean length of stay was 6.1 hours, with 2 patients requiring hospital admission. All other patients were discharged within 10 hours. One of the admitted patients experienced a postoperative seizure that was later determined to be secondary to drug use and serotonin syndrome. The second patient developed an anterior cervical hematoma 5 hours postoperatively, which was immediately evacuated. The patient was admitted for observation and discharged the next day. CONCLUSION In our study, patients experienced considerable improvement in disability scores, with a low likelihood of postoperative complications. A safe and effective MMA protocol may help facilitate anterior cervical surgery in the outpatient setting. LEVEL OF EVIDENCE 3. CLINICAL RELEVANCE Transitioning anterior cervical discectomy and fusions to the ASC requires an appropriate MMA protocol. Our findings reveal that an enhanced MMA protocol will help improve disability scores while keeping the likelihood of postoperative complications low. This supports the ASC setting for cervical spine procedures in appropriate patient populations.

The influence of cognitive behavioral therapy on lumbar spine surgery outcomes: a systematic review and meta-analysis. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2021; 30:1365-1379. [PMID: 33566172 DOI: 10.1007/s00586-021-06747-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 12/14/2020] [Accepted: 01/20/2021] [Indexed: 12/19/2022]
Abstract
PURPOSE As more patients undergo lumbar spine surgery, novel interventions may improve physical and mental health outcomes. Few studies summarize the benefit of cognitive behavioral therapy (CBT) among lumbar spine surgery patients. This study collects randomized control trial data to investigate the influence of CBT on patient reported outcomes among lumbar spine surgery patients. METHODS Our study used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and a medical library expert assisted in searching PubMed/MEDLINE, Scopus, CINAHL, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, PsycINFO, and Google Scholar. We calculated standardized mean differences (SMD) to evaluate the effect size of CBT versus control groups with a sensitivity analysis. RESULTS Our meta-analysis included seven studies with a total of 531 patients. The majority of included studies evaluated lumbar fusion, with preoperative CBT performed by physiotherapists. The largest effects were observed for overall quality of life (SMD = 0.55 [95% CI 0.05, 1.05], p < 0.001, I2 = 86.7%) and psychological outcomes (SMD = 0.61 [95% CI 0.28, 0.94], p < 0.001, I2 = 89.7%) though disability and pain outcomes also favored CBT intervention. Included studies demonstrated low overall bias but large heterogeneity. Sensitivity analysis demonstrated negligible study design differences and revealed moderators including CBT session frequency and final follow-up duration (p < 0.001). CONCLUSION Compared to usual care or alternative therapy control arms, CBT delivered the most improvement with overall quality of life and psychological outcomes. Among appropriately selected patients, CBT could improve perioperative disability, pain, quality of life, and psychological health following lumbar spine surgery.

Abstract
BACKGROUND Preoperative depression is associated with increased perioperative pain, worse physical function, reduced quality of life, and inferior outcomes. Few studies have evaluated depressive symptoms between genders for individuals undergoing minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). The purpose of this investigation was to assess the severity of Patient Health Questionnaire-9 (PHQ-9) scores among patients with depressive symptoms before and after single-level MIS TLIF. METHODS A prospective surgical registry was retrospectively reviewed for spine surgeries between March 2016 and December 2018. We included patients with at least mild depressive symptoms (PHQ-9 scores ≥ 5) who underwent primary, single-level MIS TLIF and compared genders using χ2 tests and t tests. Genders were stratified by depressive symptom severity: mild (5-9), moderate (10-14), and moderately severe (≥15) and then analyzed at preoperative and postoperative intervals: 6 weeks, 12 weeks, 6 months, and 1 year. Finally, PHQ-9 scores were validated with a Pearson correlation test against the 12-item Short Form (SF-12) Mental Composite Score (MCS) and the Veterans RAND (VR-12) MCS. RESULTS Of 75 subjects, 44.0% were women and the mean age was 49.9 years. The preoperative distribution among PHQ-9 subgroups was 38.7%, 26.6%, and 34.7% for mild, moderate, and moderately severe depressive symptoms, respectively. Among PHQ-9 stratifications both genders demonstrated intermittent statistically significant improvements in PHQ-9 scores. The moderately severe PHQ-9 subgroup had improvement at all postoperative time points. The PHQ-9 scores demonstrated a strong correlation with the SF-12 MCS and VR-12 MCS at all postoperative evaluations. CONCLUSION At baseline and by the final 1-year follow-up there were no statistically significant PHQ-9 score differences between genders within any depressive symptom stratifications. Whereas some contend that men and women have substantial mental health differences, this study is aligned with growing evidence that demonstrates similar depressive symptoms between genders. LEVEL OF EVIDENCE 3. CLINICAL RELEVANCE Men and women may be at an equivalent risk for perioperative depressive symptoms.

Abstract
OBJECTIVE While visual analogue score (VAS) metrics are among the most universally adopted patient-reported outcome measures (PROMs), there is limited research on the influence of back and leg pain on the Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) scores. Here we assess the association of VAS back and VAS leg scores with PROMIS PF in the setting of minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). Secondarily, we determine if PROMIS PF is more influenced by back or leg pain. METHODS A prospective surgical registry was reviewed from May 2015 to November 2018. Inclusion criteria were primary, single-level MIS TLIFs. We excluded multilevel procedures and patients without preoperative PROMs. Pre- and postoperative PROMIS PF, VAS back, and VAS leg scores were recorded at 6 weeks, 12 weeks, 6 months, and 1 year. A Pearson correlation evaluated PROMIS PF association with VAS back and VAS leg scores. A Fisher z-test compared correlations. Linear regression evaluated PROMIS with VAS back and VAS leg scores. RESULTS Our cohort was comprised of 146 subjects. 40.4% were female and the average age of 51 years. VAS back demonstrated a stronger correlation than VAS leg with PROMIS PF at all timepoints. PROMIS PF scores were negatively associated with both VAS back and VAS leg at all timepoints. Fisher z-test revealed VAS back to have a stronger correlation with PROMIS PF (p = 0.025) than VAS leg. CONCLUSION In the setting of MIS TLIF, physical function as evaluated by PROMIS PF, had a stronger correlation with VAS back than VAS leg at 6 months. This suggests that postoperative PROMIS PF scores may be more influenced by back pain than with leg pain.

Abstract
BACKGROUND The transition of minimally invasive (MIS) spine surgery from the inpatient to outpatient setting has been aided by advances in multimodal analgesic (MMA) protocols. This clinical case series of patients demonstrates the feasibility of ambulatory MIS transforaminal lumbar interbody fusion (TLIF) and lateral lumbar interbody fusion (LLIF) procedures while using an enhanced MMA protocol. METHODS Consecutive MIS TLIF or LLIF procedures with percutaneous pedicle screw fixation and direct decompression in the ambulatory setting were reviewed. The procedures were performed using an MMA protocol. The ambulatory surgery center (ASC) did not allow for observation of patients for periods of time greater than 23 hours. We recorded patient demographics, perioperative, and postoperative characteristics. RESULTS Fifty consecutive patients were identified from September 2016 to July 2019. Forty-one patients (82%) underwent MIS TLIF, and 9 patients underwent MIS LLIF (18.0%). All patients were discharged on the same day of surgery. The mean length of stay was 4.5 hours and 3.8 hours for the TLIF and LLIF cohorts, respectively. Our review of medical records revealed no postoperative complications following either the TLIF or the LLIF procedures. CONCLUSIONS The present study of 50 consecutive patients is the largest clinical series of ASC patients undergoing lumbar fusion procedures in a stand-alone facility with no extended postoperative observation capability. While using MMA protocol within the ASC, no postoperative complications were observed for either MIS TLIF or LLIF procedures. All patients were discharged from the ambulatory surgical center on the day of surgery with well-controlled postoperative pain. LEVEL OF EVIDENCE 4. CLINICAL RELEVANCE The MMA protocol is an essential aspect in transitioning minimally invasive lumbar spine surgery to the ASC. Our findings indicate that MIS lumbar fusion spine surgery with an enhanced MMA protocol can lead to safe and timely ASC discharge while minimizing hospital admission.

Abstract
Study Design: This is a retrospective cohort study. Introduction: Spine procedures are the most expensive surgical interventions on a per-case basis. Previously, orthopedic procedures occurring later in the week have been associated with an increased length of stay (LOS) and consequent increase in costs. However, no such analysis has been performed on common spinal procedures such as minimally invasive lumbar decompression (MIS LD). The purpose of this study is to determine if there is an association between day of surgery and LOS or direct hospital costs after MIS LD. Materials and Methods: A prospectively maintained surgical database of patients who underwent primary, single, or multilevel MIS LD for degenerative spinal pathology between 2008 and 2017 was reviewed. Patients undergoing MIS LD were grouped as early in the week (Monday/Tuesday) or late in the week (Thursday/Friday). Differences in patient demographics and preoperative characteristics were compared using χ 2 analysis or Student’s t-test. Associations between date of surgery, LOS, and costs were assessed using multivariate linear regression. Results: A total of 717 patients were included. Of these, 420 (58.6%) were in the early surgery cohort and 297 (41.4%) were in the late surgery cohort. There were no differences in demographic characteristics, operative levels, operative time, blood loss, or hospital LOS between cohorts ( p > 0.05). Furthermore, there was no difference in total direct costs or specific cost categories between cohorts ( p > 0.05). Discussion: The timing of surgery within the week is not associated with differences in inpatient LOS or hospital costs following MIS LD. As such, hospitals should not alter surgical scheduling patterns to restrict these procedures to certain days within the week.

Abstract
BACKGROUND Development and validation of Veterans RAND 12-item (VR-12) physical component survey (PCS) has been established among civilian and veteran populations but it has not been examined among anterior cervical discectomy and fusion (ACDF) patients. PURPOSES/QUESTIONS We sought to validate legacy patient-reported outcome measures (PROMs) with VR-12 PCS among patients undergoing ACDF procedures. METHODS A prospectively collected surgical registry was retrospectively evaluated for elective single or multi-level ACDFs performed for degenerative spinal pathologies from January 2014 to August 2019. Exclusion criteria included missing pre-operative surveys and surgery for trauma, metastasis, or infection. Demographic variables, baseline pathologies, and peri-operative variables were collected. A paired t test evaluated the change from the pre-operative score to each post-operative timepoint for VR-12 PCS, the 12-item Short-Form Survey (SF-12) PCS, Patient-Reported Outcomes Measurement Information System physical function (PROMIS-PF), and Neck Disability Index (NDI). Minimal clinically important difference (MCID) achievement was calculated at each timepoint. Correlation was evaluated with a Pearson's correlation coefficient and time-independent partial correlation. RESULTS Of the 202 patients who underwent ACDF, 41.1% were female and the average age was 49.5 years. All PROMs had statistically significantly increased from baseline when compared with post-operative timepoints (12 weeks, 6 months, 1 year, and 2 years). MCID achievement rates increased through 2 years. All timepoints revealed strong VR-12 PCS correlations with SF-12 PCS, PROMIS-PF, and NDI scores. CONCLUSION VR-12 PCS was strongly correlated with the well-validated SF-12 PCS and NDI metrics as well as with the more recent PROMIS-PF. All PROMs demonstrated statistically significant improvement in patients post-operatively. VR-12 PCS is a valid measure of physical function among patients undergoing ACDF.

Abstract
STUDY DESIGN Retrospective. OBJECTIVE To determine the association between preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) scores with postoperative pain, narcotics use, and patient-reported outcomes (PRO) following a single-level anterior cervical discectomy and fusion (ACDF) procedure. SUMMARY OF BACKGROUND DATA There is a scarcity of prior literature on the ability of baseline PROMIS scores to predict clinical outcomes for patients undergoing ACDF procedures. METHODS Patients who underwent a primary ACDF were retrospectively reviewed and stratified into low and high disability cohorts. Preoperative PROMIS PF cohorts were tested for association with demographic and perioperative characteristics using chi-square analysis and one-way analysis of variance. Cohorts were tested for association with inpatient pain scores and narcotics consumption, as well as postoperative improvements in PROMIS PF, neck disability index (NDI), and visual analog scale (VAS) neck and arm pain using linear regression. RESULTS Ninety one patients were included: 39 low disability and 52 high disability. Inpatient postoperative VAS pain scores and narcotic consumption are also compared between cohorts. Patients with greater disability reported higher VAS pain scores (P = 0.003). However, patients in both cohorts consumed comparable amounts of narcotics (P = 0.926). Patients with greater preoperative disability demonstrated lower PROMIS PF scores, greater NDI scores, and greater VAS Neck scores at the preoperative baseline. However, patients demonstrated similar improvement of VAS neck and arm pain, as well as NDI at all postoperative timepoints. Patients with low disability reported worsened physical function at the 6 weeks timepoint. CONCLUSION Patients with worse preoperative disability as measured by PROMIS PF reported increased pain but comparable narcotics consumption in the immediate postoperative period following a single-level ACDF procedure. Furthermore, patients experienced similar long-term postoperative improvement of PROs regardless of preoperative physical function. PROMIS PF can efficiently quantify physical function before and after the ACDF procedure as self-evaluated by patients. LEVEL OF EVIDENCE 3.

Abstract
In this review, we discuss the demonstrated value of vitamin D in bone maintenance, fracture resistance, spinal health, and spine surgery outcomes. Despite this, the effect of vitamin D levels in spine surgery has not been well described. Through this review of literature, several conclusions were drawn. First, despite the fact that a high number of spine surgery patients are vitamin D deficient, screening is not commonly performed. Second, adequate vitamin D levels will not be achieved in a majority of these patients without supplementation. Last, inadequate vitamin D levels may increase the risk of pseudarthrosis. Given these findings, we suggest that many patients undergoing spinal surgery could be treated with vitamin D supplementation prior to surgery without the need for confirmatory testing for vitamin D deficiency. This is a more cost-effective method than screening all patients. However, future randomized trials and cost-effectiveness analyses are needed to determine the ultimate effects of vitamin D supplementation on clinical morbidity and surgical outcomes.

Association of Preoperative PROMIS Scores With Short-term Postoperative Improvements in Physical Function After Minimally Invasive Transforaminal Lumbar Interbody Fusion. Neurospine 2020; 17:417-425. [PMID: 32615700 PMCID: PMC7338959 DOI: 10.14245/ns.2040048.024] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2020] [Accepted: 03/08/2020] [Indexed: 11/28/2022] Open
Abstract
Objective This study examines the associations between preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) score, measured by PROMIS-PF and the change between pre- and postoperative PROMIS-PF scores.
Methods A prospectively maintained surgical registry was retrospectively reviewed for spine surgeries between May 2015–June 2019. Inclusion criteria were primary, single-level minimally invasive transforaminal lumbar interbody fusions. Revisions, multilevel procedures, and patients missing preoperative surveys were excluded. Patients were grouped by preoperative PROMIS-PF scores of ≥ 35 and < 35, with higher scores indicating greater PF. A chi-squared and Student t-test were used to analyze categorical and continuous variables respectively. Linear regression evaluated the relationship of PROMIS-PF score improvement.
Results Of the 180 subjects, 84 were in the PROMIS-PF < 35 group which had more obese patients (p < 0.001) and more males (p = 0.001). Length of stay was greater for the PROMIS-PF < 35 group (36.2 hours vs. 28.7 hours, p = 0.014). PROMIS-PF and Oswestry Disability Index scores were significantly different between subgroups at all timepoints. PROMIS-PF < 35 cohort had larger postoperative PROMIS-PF improvements at 6 weeks (p = 0.008) and 12 weeks (p = 0.003). Linear regression demonstrated a negative association between preoperative PROMIS-PF scores and improvement at 6 weeks, 12 weeks, 6 months, and 2 years (p < 0.001). PROMIS-PF < 35 demonstrated significantly lower rate of achieving minimum clinically important difference at 6 months, otherwise no difference observed throughout the 2-year follow-up.
Conclusion Up to 6 months postoperatively, lower preoperative PROMIS-PF scores were associated with larger PROMIS-PF improvements. Understanding the relationship preoperative PROMIS-PF scores have with postoperative improvement may enable better patient counseling.

Predictors of inpatient admission in the setting of anterior lumbar interbody fusion: a Minimally Invasive Spine Study Group (MISSG) investigation. J Neurosurg Spine 2020; 33:446-454. [PMID: 32442965 DOI: 10.3171/2020.3.spine20134] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2020] [Accepted: 03/18/2020] [Indexed: 11/06/2022]
Abstract
OBJECTIVE While the anterior lumbar interbody fusion (ALIF) procedure may be amenable to ambulatory surgery, it has been hypothesized that limitations such as the risk of postoperative ileus and vascular complications have hindered transition of this procedure to the outpatient setting. Identification of independent risk factors predisposing patients to inpatient stays of ≥ 24 hours after ALIF may facilitate better postsurgical outcomes, target modifiable risk factors, and assist in the development of screening tools to transition appropriate patients to the ambulatory surgery center (ASC) setting for this procedure. The purpose of this study was to identify the most relevant risk factors that predispose patients to ≥ 24-hour admission following ALIF. METHODS A prospectively maintained surgical registry was reviewed for patients undergoing single ALIF between May 2006 and December 2019. Demographics, preoperative diagnosis, perioperative variables, and postoperative complications were evaluated according to their relative risk (RR) elevation for an inpatient stay of ≥ 24 hours. A Poisson regression model was used to evaluate predictors of inpatient stays of ≥ 24 hours. Risk factors for inpatient admission of ≥ 24 hours were identified with a stepwise backward regression model. RESULTS A total of 111 patients underwent single-level ALIF (50.9% female and 52.6% male, ≤ 50 years old). Eleven (9.5%) patients were discharged in < 24 hours and 116 remained admitted for ≥ 24 hours. The average inpatient stay was > 2 days (53.7 hours). The most common postoperative complications were fever (body temperature ≥ 100.4°F; n = 4, 3.5%) and blood transfusions (n = 4, 3.5%). Bivariate analysis revealed a preoperative diagnosis of retrolisthesis or lateral listhesis to elevate the RR for an inpatient stay of ≥ 24 hours (RR 1.11, p = 0.001, both diagnoses). Stepwise multivariate analysis demonstrated significant predictors for inpatient stays of ≥ 24 hours to be an operation on L4-5, coexisting degenerative disc disease (DDD) with foraminal stenosis, and herniated nucleus pulposus (RR 1.11, 95% CI 1.03-1.20, p = 0.009, all covariates). CONCLUSIONS This study provides data regarding the incidence of demographic and perioperative characteristics and postoperative complications as they pertain to patients undergoing single-level ALIF. This preliminary investigation identified the most relevant risk factors to be considered before appropriately transitioning ALIF procedures to the ASC. Further studies of preoperative characteristics are needed to elucidate ideal ASC ALIF patients.

Abstract
PURPOSE To evaluate specific demographic and perioperative variables associated with higher inpatient pain scores following minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). METHODS Patients who underwent a single-level, primary MIS TLIF were retrospectively reviewed. Perioperative outcomes were collected, and postoperative inpatient VAS pain scores were measured. Both bivariate and stepwise multivariate Poisson regressions with robust error variance were used to assess risk factors for average inpatient pain score ≥ 5.0. A final backward stepwise regression model was created using age, gender, smoking status, diabetes status, insurance status, BMI, comorbidity burden, pedicle screw laterality, operative time, and estimated blood loss. RESULTS A total of 255 patients undergoing primary, single-level MIS TLIF were included. Age less than 50 years, workers' compensation insurance, preoperative VAS pain score ≥ 7, and operative duration ≥ 110 min were associated with greater postoperative pain. However, other variables such as gender, BMI, smoking status, comorbidity burden, diabetes status, and pedicle screw laterality were not associated with increased postoperative pain. CONCLUSION The results of this study suggest that younger age, workers' compensation, elevated preoperative pain scores, and longer operative times are independently associated with greater inpatient pain following TLIF. Surgeons can use this information to better assess which patients may require additional pain control following TLIF. Patient expectations of postoperative outcomes in regard to pain and recovery may also be better managed. These slides can be retrieved under Electronic Supplementary Material. (paragraph).

Abstract
OBJECTIVE To assess the relationship of preoperative physical function, as measured by Patient-Reported Outcome Measurement Information System Physical Function (PROMIS PF), to improvement in mental health, as evaluated by Short Form-12 Mental Component Summary (SF-12 MCS) following anterior cervical discectomy and fusion (ACDF). METHODS Patients undergoing primary ACDF were retrospectively reviewed and stratified based on preoperative PROMIS PF scores. PROMIS PF cohorts were tested for an association with demographic characteristics and perioperative variables using chi-square analysis and multivariate linear regression. Multivariate linear regression was utilized to determine the association between PROMIS PF cohorts and improvement in SF-12 MCS. RESULTS A total of 129 one- to 3-level ACDF patients were included: 73 had PROMIS PF < 40 ("low PROMIS") and 56 had PROMIS PF ≥ 40 ("high PROMIS"). The low PROMIS cohort reported worse mental health preoperatively and at all postoperative timepoints except for 1 year. Both cohorts had similar changes in mental health from baseline through the 6-month follow-up. However, at 1 year. postoperatively, the low PROMIS cohort had a statistically greater change in mental health score. CONCLUSION Patients with worse preoperative physical function reported significantly worse preoperative and postoperative mental health. However, patients with worse preoperative physical function made significantly greater improvements in mental health from baseline. This suggests that patients with worse preoperative physical function can still expect significant improvements in mental health following surgery.

Abstract
OBJECTIVE Assess preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) scores and differences between preoperative and postoperative PROMIS-PF scores for patients undergoing anterior cervical discectomy and fusion (ACDF). METHODS After Institutional Review Board approval, a prospectively maintained surgical registry was retrospectively reviewed for elective spine surgeries of nontraumatic, degenerative pathology between 2015-2018. Inclusion criteria were primary or revision, single-level ACDF procedures. Multilevel procedures and patients without preoperative surveys were excluded. A preoperative PROMIS score cutoff of 35 divided patients into PROMIS-PF score categories (e.g. , ≥ 35.0, < 35.0). Categorical and continuous variables were evaluated with chi-square tests and t-tests. Linear regression analyzed PROMIS-PF score improvement. RESULTS Eighty-six patients were selected, the high and low PROMIS-PF subgroups only differed in mean age (49.1 vs. 41.3, p = 0.002). Significant differences in PROMIS-PF scores were observed among high and low preoperative PROMIS-PF score subgroups at 6 weeks (p = 0.006), 12 weeks (p = 0.006), and 6 months (p = 0.014). Mean differences between preoperative and postoperative PROMIS-PF scores were significantly different between the high and low PROMIS-PF subgroups at 6 weeks (p = 0.041) and 1 year (p = 0.038). A significant negative association was observed between preoperative PROMIS scores and magnitude of improvement at the 6-week postoperative time point (slope = -0.6291, p < 0.001). CONCLUSION Patients with low preoperative PROMIS-PF scores demonstrated greater improvements at 6 weeks and 1 year. Clinicians should consider patients with low preoperative PROMIS-PF scores to be in the unique position to potentially experience larger postoperative improvement magnitudes than patients with higher preoperative PROMIS-PF scores.

Abstract
PURPOSE Our aim is to examine the gender performance of Patient-Reported Outcome Measurement Information System Physical Function (PROMIS-PF) scores among patients undergoing minimally invasive transforaminal lumbar fusion (MIS TLIF). METHODS A prospectively collected surgical dataset was retrospectively assessed for eligible patients from March 2015-June 2019. We included patients if they underwent primary MIS TLIF procedures on one or two vertebral levels. We collected baseline demographics, perioperative characteristics, and PROMIS-PF scores for each subject at pre and postoperative timepoints (e.g., 6-weeks, 3-months, 6-months, and 1-year). Chi-squared analyses were utilized to assess categorical variables and a Student's t-tests analyzed continuous variables. A linear regression was used to analyze PROMIS-PF scores from baseline through all postoperative time points. Finally, we evaluated the PROMIS PF achievement of minimal clinically important difference (MCID) among gender. RESULTS 192 patients were included: 77 were females and 115 were males. No significant differences were observed among gender subgroups for PROMIS-PF scores at pre- or postoperative evaluations. Compared to males, females experienced significantly greater postoperative improvement with PROMIS-PF scores at the 3-month assessments, though no significant gender differences were observed during later follow-up evaluations at 6-months or one year. Females were observed to have significant PROMIS-PF score improvement from their preoperative evaluation to each postoperative score. Males were assessed to have statistically significant postoperative (e.g., at 3-months, 6-months, and 1-year) PROMIS-PF score improvement from their preoperative PROMIS-PF scores. There were no significant differences among gender in achieving MCID at any postoperative time interval. CONCLUSION Among gender, we observed no statistically significant difference in PROMIS-PF scores during the pre- or postoperative evaluations. Additionally, with no difference in the rate of achieving PROMIS-PF MCID postoperatively, this study established that both genders should experience similar functional outcomes following MIS TLIF.

Abstract
As the number of advances in surgical techniques increases, it becomes increasingly important to assess and research the technology regarding spine surgery techniques in order to increase surgical accuracy, decrease overall length of surgery, and minimize overall radiation exposure. Currently, augmented reality and virtual reality have shown promising results in regard to their applicability beyond their current functions. At present, VR has been generally applied to a teaching and preparatory role, while AR has been utilized in surgical settings. As such, the following review attempts to provide an overview of both virtual reality and augmented reality, followed by a discussion of their current applications and future direction.

Abstract
An increasing variety of orthobiologic materials, including autologous and allogeneic bone graft, bone marrow aspirate, demineralized bone matrix, ceramics, and growth factors are available to the spine surgeon. Although autologous bone graft remains the gold standard material, concerns for failure in achieving fusion have prompted evaluation of current and new biologic materials. As such, this review attempts to summarize the available biologic materials with their pertinent characteristics, advantages, disadvantages, and primary uses.
