RESUMEN
OBJECTIVE: Surgical decompression is often indicated for symptomatic cases of cervical radiculopathy. In the cervical spine, minimally invasive posterior cervical foraminotomy (MIS-PCF) and the anterior transcorporeal approach (ATCA) are modern techniques available to surgeons. This systematic review and single-arm meta-analysis aimed to assess surgical and patient-reported outcomes of MIS-PCF and ATCA for cervical radiculopathy. METHODS: A systematic review of the literature was conducted using 1) Ovid; 2) Epub Ahead of Print and In-Process, In-Data-Review & Other Non-Indexed Citations; and 3) Scopus databases, which reported outcomes following cervical decompression using MIS-PCF or the ATCA. Specifically, baseline characteristics, operative outcomes, and changes in visual analog scale (VAS) neck pain score were assessed. The quality of the studies was graded using the modified Newcastle-Ottawa Scale for observational studies. RESULTS: Forty studies with 1661 patients were identified. The comparative analysis of both techniques revealed no significant differences in complication (7%, 95% CI 5%-10%, p = 0.75) or reoperation rates (5%, 95% CI 3%-7%, p = 0.41). Additionally, there were no significant differences in estimated blood loss (55.39, 95% CI 44.62-66.16 ml, p = 0.55) or operative time (85.15, 95% CI 65.38-104.92 minutes, p = 0.05). The ATCA showed significantly greater improvement (p < 0.01) in VAS neck pain scores following surgery (ATCA point reduction 6.7, 95% CI 6.0-7.5 points vs MIS-PCF 3.0, 95% CI 1.0-5.0 points). CONCLUSIONS: The ATCA and MIS-PCF are effective modern techniques for the surgical treatment of radiculopathy. Both approaches showed comparable postoperative outcomes, including complication and reoperation rates. However, the ATCA was shown to provide significantly greater improvement in VAS neck pain scores.
RESUMEN
BACKGROUND: Depression and anxiety are common in patients undergoing spinal surgery and might negatively impact outcomes. This study investigates the possible effect of these diagnoses on patient reported outcomes following lumbar fusion. METHODS: Retrospective review of a registry containing prospectively collected data of lumbar fusion procedures at a single institution was performed from May 23, 2012 to June 15, 2022. Patients with a minimum of two year follow-up were included. Demographic information, diagnoses, medications, patient-reported outcomes measures (PROMs), and complications data at preoperative, three months, six months, 1 year, and two years postoperative were collected. Statistical analysis was performed using Student's t-tests, χ2, binomial correlation, odds ratios, logistic regression, and mean clinically important difference. RESULTS: A total of 156 patients were included (60 males, 96 females) with mean age 62.6 ± 11.1 years at surgery. Thirty-nine (25%) had depression and/or anxiety (DA). Baseline Oswestry Disability Index (ODI) and EuroQol Group 5D questionnaire (EQ5D) scores were significantly worse in the DA cohort compared to controls (ODI 51.1 ± 18.3 vs. 42.9 ± 15.8; P = 0.010, EQ5D 0.46 ± 0.21 vs. 0.57 ± 0.21; P = 0.005). Both cohorts experienced similar relative improvement at two years (delta ODI -18.2 ± 27.9 vs. -17.8 ± 22.1; P = 0.924, EQ5D 6.8 ± 33.8 vs. 8.1 ± 32.9; P = 0.830). Absolute outcome scores were worse in the DA cohort at all intervals. DA were not independently predictive of changes in PROMs (delta ODI mean difference 4.49, r2 = 0.36, P = 0.924). CONCLUSIONS: The present study showed similar improvement in PROMs following lumbar fusion for patients with anxiety and depression compared to healthy controls. These data suggest these patients are no less likely to benefit from appropriately planned lumbar fusion.

INTRODUCTION: Neurogenic bladder is a common complication after spinal cord injury (SCI) that carries substantial burdens on the inflicted individual. The objective of this study is to build a prediction model for neurogenic bladder recovery 1 year after traumatic SCI. METHODS: We queried the National Spinal Cord Injury Model Systems database for patients with traumatic SCI who had neurogenic bladder at the time of injury. The primary outcome of interest was the complete recovery of bladder function at 1 year. Multiple imputations were performed to generate replacement values for missing data, and the final imputed data were used for our analysis. A multivariable odds logistic regression model was developed for complete bladder recovery at 1 year. RESULTS: We identified a total of 2515 patients with abnormal bladder function at baseline who had an annual follow-up. A total of 417 patients (16.6%) recovered bladder function in 1 year. Predictors of complete bladder recovery included the following baseline parameters: sacral sensation, American Spinal Injury Association (ASIA) impairment score, bowel function at baseline, voluntary sphincter contraction, anal sensation, S1 motor scores, and the number of days in the rehabilitation facility. The model performed with a discriminative capacity of 90.5%. CONCLUSIONS: We developed a prediction model for the probability of complete bladder recovery 1 year after SCI. The model performed with a high discriminative capacity. This prediction model demonstrates potential utility in the counseling, research allocation, and management of individuals with SCI.

INTRODUCTION: Meningiomas account for over 30% of all primary brain tumors. While surgery can be curative for these tumors, several factors may lead to a higher likelihood of recurrence. For recurrent meningiomas, bevacizumab may be considered as a therapeutic agent, but literature regarding its efficacy is sparse. Thus, we present a systematic review of the literature and case series of patients from our institution with treatment-refractory meningiomas who received bevacizumab. METHODS: Patients at our institution who were diagnosed with recurrent meningioma between January 2000 and September 2020 and received bevacizumab monotherapy were included in this study. Bevacizumab duration and dosages were noted, as well as progression-free survival (PFS) after the first bevacizumab injection. A systematic review of the literature was also performed. RESULTS: Twenty-three patients at our institution with a median age of 55 years at initial diagnosis qualified for this study. When bevacizumab was administered, 2 patients had WHO grade I meningiomas, 10 patients had WHO grade II meningiomas, and 11 patients had WHO grade III meningiomas. Median PFS after the first bevacizumab injection was 7 months. Progression-free survival rate at 6 months was 57%. Two patients stopped bevacizumab due to hypertension and aphasia. Systematic review of the literature showed limited ability for bevacizumab to control tumor growth. CONCLUSION: Bevacizumab is administered to patients with treatment-refractory meningiomas and, though its effectiveness is limited, outperforms other systemic therapies reported in the literature. Further studies are required to identify a successful patient profile for utilization of bevacizumab.

BACKGROUND: The adoption of the transradial approach (TRA) has been increasing in popularity as a primary method to conduct both diagnostic and therapeutic interventions. As this technique gains broader acceptance and use within the neuroendovascular community, comparing its complication profile with a better-established alternative technique, the transfemoral approach (TFA), becomes more important. This study aimed to evaluate the safety of TRA compared with TFA in patients undergoing diagnostic, therapeutic, and combined neuroendovascular procedures. METHODS: A systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A literature search of PubMed and other databases was conducted for studies from all available dates. To compare TRA and TFA, we performed an indirect meta-analysis between studies that mentioned the complications of the procedures. RESULTS: Our search yielded 532 studies, of which 108 met full inclusion criteria. A total of 54,083 patients (9137 undergoing TRA and 44,946 undergoing TFA) were included. Access site complication rate was lower in TRA (1.62%) compared with TFA (3.31%) (P < 0.01). Neurological complication rate was lower in TRA (1.64%) compared with TFA (3.82%) (P = 0.02 and P < 0.01, respectively). Vascular spasm rate was higher in TRA (3.65%) compared with TFA (0.88%) (P < 0.01). Wound infection complication rate was higher in TRA (0.32%) compared with TFA (0.2%) (P < 0.01). CONCLUSIONS: Patients undergoing TFA are significantly more likely to experience access site complications and neurological complications compared with patients undergoing TRA. Patients undergoing TRA are more likely to experience complications such as wound infections and vascular spasm.

BACKGROUND: The utility of intraoperative neurophysiological monitoring (IONM) is well established for some spine surgeries (eg, intramedullary tumor resection, scoliosis deformity correction), but its benefit for most degenerative spine surgery, including anterior cervical discectomy and fusion (ACDF), remains debated. National datasets provide "big data" approaches to study the impact of IONM on spine surgery outcomes; however, if administrative coding in these datasets misrepresents actual IONM usage, conclusions will be unreliable. The objective of this study was to compare estimated rates (administrative coding) to actual rates (chart review) of IONM for ACDF at our institution and extrapolate findings to estimated rates from 2 national datasets. METHODS: Patients were included from 3 administrative coding databases: the authors' single institution database, the Nationwide Inpatient Sample (NIS), and the National Surgical Quality Improvement Program (NSQIP). Estimated and actual institutional rates of IONM during ACDF were determined by administrative codes (International Classification of Diseases [ICD] or Current Procedural Terminology [CPT]) and chart review, respectively. National rates of IONM during ACDF were estimated using the NIS and NSQIP datasets. RESULTS: Estimated institutional rates of IONM for ACDF were much higher with CPT than ICD coding (73.2% vs 16.5% in 2019). CPT coding for IONM better approximated actual IONM usage at our institution (74.6% in 2019). Estimated IONM utilization rates for ACDF in national datasets varied widely: 0.76% in CPT-based NSQIP and 18.4% in ICD-based NIS. CONCLUSIONS: ICD coding underestimated IONM usage during ACDF at our institution, whereas CPT coding was more accurate. Unfortunately, the CPT-based NSQIP is nearly devoid of IONM codes, as it has not been a collection focus of that surgical registry. ICD-based datasets, such as the NIS, likely fail to accurately capture IONM usage. Multicenter and/or national datasets with accurate IONM utilization data are needed to inform surgeons, insurers, and guideline authors on whether IONM has benefit for various spine surgery types. CLINICAL RELEVANCE: Currently available national databases based on administrative codes do not accurately reflect IONM usage.
RESUMEN
STUDY DESIGN: Systematic Review and Meta-analysis. OBJECTIVE: The purpose of this study is to synthesize recommendations for perioperative medical management of RA patients and quantify outcomes after spine surgery when compared to patients without RA. METHODS: A search of available literature on patients with RA and spine surgery was performed. Studies were included if they provided a direct comparison of outcomes between patients undergoing spine surgery with or without RA diagnosis. Meta-analysis was performed on operative time, estimated blood loss, hospital length of stay, overall complications, implant-related complications, reoperation, infection, pseudarthrosis, and adjacent segment disease. RESULTS: Included in the analysis were 9 studies with 703 patients with RA undergoing spine surgery and 2569 patients without RA. In RA patients compared to non-RA patients undergoing spine surgery, the relative risk of infection was 2.29 times higher (P = .036), overall complications 1.61 times higher (P < .0001), implant-related complications 3.93 times higher (P = .009), and risk of reoperation 2.45 times higher (P < .0001). Hospital length of stay was 4.6 days longer in RA patients (P < .0001). CONCLUSIONS: Treatment of spinal pathology in patients with RA carries an increased risk of infection and implant-related complications. Spine-specific guidelines for perioperative management of antirheumatic medication deserve further exploration. All RA patients should be perioperatively co-managed by a rheumatologist. This review helps identify risk profiles in RA specific to spine surgery and may guide future studies seeking to medically optimize RA patients perioperatively.
RESUMEN
BACKGROUND: The emergence of C8 radiculopathy is a known complication following cervicothoracic osteotomies. However, the clinical profile of C8 radiculopathy is not well understood. The aim of this study was to investigate the rate of C8 radiculopathy after cervicothoracic osteotomies and to form a clinical profile describing the characteristics through a systematic review of the literature. METHODS: An electronic database search for full-text English articles was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The search yielded results on indications for cervicothoracic osteotomies, surgical approaches, mean follow-up time, and significant complications, including C8 radiculopathy. RESULTS: Our literature search yielded 2135 articles, of which 12 qualified to be included in the analysis. The 12 articles comprised 451 patients undergoing various osteotomy approaches. The mean age of subjects was 51.0 years (range, 11.4-63.2 years), and the majority of patients were male (66%, n = 298). Ankylosing spondylitis was the most frequent indication for surgery (44.8%, n = 202). The number of patients with postoperative C8 radiculopathy was found to decrease over time (1997-2020) by showing statistical significance (r = -0.65, P = 0.021). CONCLUSIONS: Of the 451 patients included in this study, 53 had C8 radiculopathy (11.8% of the total patient population). Moreover, the rate of C8 radiculopathy decreased over time in a statistically significant manner. An understanding of the factors associated with the incidence of C8 radiculopathy is essential for future improvement of patient outcomes.

INTRODUCTION: Given the potential injury to the spinal cord and the nerve roots during the surgery and the necessity of minimal spinal cord manipulation during surgery, minimally invasive surgical techniques have emerged as alternatives to conventional open surgery in resection of ID-EM tumors. METHODS: An electronic database search was conducted, and the review was carried out according to PRISMA guidelines and recommendations. Inclusion criteria were as follows; (i) comparative studies of MIS vs OS; (ii) studies reporting outcomes for patients undergoing surgery for ID-EM tumors. Variables collected were patient demographics, estimated blood loss (EBL), mean operative time, length of stay, complications, extent of tumor resection. RESULTS: The search identified a total of 275 studies. After the selection criterion was applied 7 comparative studies were included. A total of 302 patients were included in the analysis with 149 (49.3%) of them undergoing MIS and 153 of them (50.7%) undergoing open surgery. EBL, operative time, and LOS were significantly lower in MIS group (p < 0.0001, p < 0.0001, and p = 0.0002 respectively). Two groups were similar with regards to the rates of surgical complications, medical complications and gross total resection. The most common surgical complication was CSF leak (52.3% of all complications). CONCLUSION: Results of this meta-analysis show a significant reduction in EBL, operative time, and length of stay with MIS while proving safe and preserving high rates of gross-total resection. The findings suggest that the minimally invasive spine surgery may serve as a beneficial alternative for patients undergoing spine surgery for ID-EM tumors of the spinal cord.

Importance: Maximal resection is the preferred management for sacral chordomas but can be associated with unacceptable morbidity. Outcomes with radiotherapy are poor. Carbon ion radiotherapy (CIRT) is being explored as an alternative when surgery is not preferred. Objective: To compare oncologic outcomes and treatment-related toxicity of CIRT and en bloc resection for sacral chordoma. Design, Setting, and Participants: Univariable logistic regression was performed to evaluate the association between treatment type and oncologic and toxicity outcomes in this retrospective cohort study. Nearest-neighbor propensity score matching was used to match the CIRT cohort with the en bloc resection cohort and 10 National Cancer Database (NCDB) cohorts separately, with the objective of obtaining more homogeneous cohorts when comparing treatments. Patient- and tumor-related characteristics from 2 institutional cohorts were collected for patients diagnosed with sacral chordomas between April 1, 1994, and July 31, 2017. The NCDB was queried for data on patients with sacral chordoma from January 1, 2004, to December 31, 2016, as a comparator in overall survival (OS) analyses. Data analysis was conducted from February 24, 2020, to January 16, 2021. Exposures: En bloc resection, incomplete resection, photon radiotherapy, proton radiotherapy, and CIRT. Main Outcomes and Measures: Overall survival was estimated using the Kaplan-Meier method and compared using the Cox proportional hazards model. Peripheral motor nerve toxic effects were scored using Common Terminology Criteria for Adverse Events, version 4.03. Results: A total of 911 patients were included in the study (NCDB: n = 669; median age, 64 [IQR, 52-74] years; 410 [61.3%] men; CIRT: n = 188; median age, 66 [IQR, 58-71] years; 128 [68.1%] men; en bloc surgical resection: n = 54; median age, 53.5 [IQR 49-64] years, 36 [66.7%] men). Comparison of the propensity score-matched institutional en bloc resection and CIRT cohorts revealed no statistically significant difference in OS (CIRT: median OS, 68.1 [95% CI, 44.0-102.6] months; en bloc resection: median OS, 58.6 [95% CI, 25.6-123.5] months; P = .57; hazard ratio, 0.71 [95% CI, 0.25-2.06]; P = .53). The CIRT cohort experienced lower rates of peripheral motor neuropathy (odds ratio, 0.13 [95% CI, 0.04-0.40]; P < .001). On comparison of the propensity score-matched NCDB cohorts with the CIRT cohort, significantly higher OS was found for CIRT compared with margin-positive surgery without adjuvant radiotherapy (CIRT: median OS, 64.7 [95% CI, 57.8-69.7] months; margin-positive surgery without adjuvant radiotherapy: median OS, 60.6 [95% CI, 44.2-69.7] months, P = .03) and primary radiotherapy alone (CIRT: median OS, 64.9 [95% CI 57.0-70.5] months; primary radiotherapy alone: 31.8 [95% CI, 27.9-40.6] months; P < .001). Conclusions and Relevance: These findings suggest that CIRT can be used as treatment for older patients with high performance status and sacral chordoma in whom surgery is not preferred. CIRT might provide additional benefit for patients who undergo margin-positive resection or who are candidates for primary photon radiotherapy.

INTRODUCTION: Interbody cages are currently being used to address diseases of the vertebra requiring surgical stabilization. Titanium cages were first introduced in 1988. Polyetheretherketone (PEEK) cages are used frequently as one of the alternatives to titanium cages in current practice. This study aimed to compare available cage materials by reviewing the surgical and radiographic outcomes following anterior cervical discectomy and fusion. METHODS: A comprehensive search of several electronic databases was conducted following the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. Baseline characteristics, operative outcomes, arthrodesis rates, subsidence rates, and complications were collected from included studies. Collected outcomes were further stratified according to the procedure type, the number of levels operated, and graft used to compare cage materials. RESULTS: Following the screening for inclusion criteria, a total of 37 studies with 2363 patients were included. The median age was 49.5 years and the median follow-up was 26 months. Overall, no significant differences were found between PEEK and titanium cages regarding fusion, neurologic deficit, subsidence rates, or "good and excellent" outcome according to Odom criteria. However, the standalone comparison between PEEK, titanium, and poly-methyl-methacrylate (PMMA) cages showed a significantly lower fusion rate for PMMA (PEEK: 94%, PMMA: 56%, titanium: 95%, P < 0.01). CONCLUSIONS: In the present systematic review and meta-analysis, a comparison of the long-term patient-reported and the radiographic outcomes associated with the use of titanium and PEEK, intervertebral body cages showed similar findings. However, there were significantly lower fusion rates for PMMA cages when using a standalone cage without graft material.

OBJECTIVE: Neurosurgeons generate an enormous amount of data daily. Within these data lie rigorous, valid, and reproducible evidence. Such evidence can facilitate healthcare reform and improve quality of care. To measure the quality of care provided objectively, evaluating the safety and efficacy of clinical activities should occur in real time. Registries must be constructed and collected data analyzed with the precision akin to that of randomized clinical trials to accomplish this goal. METHODS: The Quality Outcomes Database (QOD) Tumor Registry was launched in February 2019 with 8 sites in its initial 1-year pilot phase. The Tumor Registry was proposed by the AANS/CNS Tumor Section and approved by the QOD Scientific Committee in the fall of 2018. The initial pilot phase aimed to assess the feasibility of collecting outcomes data from 8 academic practices across the United States; these outcomes included length of stay, discharge disposition, and inpatient complications. RESULTS: As of November 2019, 923 eligible patients have been entered, with the following subsets: intracranial metastasis (17.3%, n = 160), high-grade glioma (18.5%, n = 171), low-grade glioma (6%, n = 55), meningioma (20%, n = 184), pituitary tumor (14.3%, n = 132), and other intracranial tumor (24%, n = 221). CONCLUSIONS: The authors have demonstrated here, as a pilot study, the feasibility of documenting demographic, clinical, operative, and patient-reported outcome characteristics longitudinally for 6 common intracranial tumor types.

PURPOSE: A chromosomal 1p/19q codeletion was included as a required diagnostic component of oligodendrogliomas in the 2016 World Health Organization (WHO) classification of central nervous system tumors. We sought to evaluate disparities in reported testing for 1p/19q codeletion among oligodendroglioma and oligoastrocytoma patients before and after the guidelines. METHODS: The National Cancer Database (NCDB) was queried for patients with histologically-confirmed WHO grade II/III oligodendroglioma or oligoastrocytoma from 2011-2017. Adjusted odds of having a reported 1p/19q codeletion test for patient- and hospital-level factors were calculated before (2011-2015) and after (2017) the guidelines. The adjusted likelihood of receiving adjuvant treatment (chemotherapy and/or radiotherapy) based on reported testing was also evaluated. RESULTS: Overall, 6,404 patients were identified. The reported 1p/19q codeletion testing rate increased from 45.8% in 2011 to 59.8% in 2017. From 2011-2015, lack of insurance (OR 0.77; 95% CI 0.62-0.97;p=0.025), lower zip code-level educational attainment (OR 0.62; 95% CI 0.49-0.78;p<0.001), and Northeast (OR 0.68; 95% CI 0.57-0.82;p<0.001) or Southern (OR 0.62; 95% CI 0.49-0.79;p<0.001) facility geographic region were negatively associated with reported testing. In 2017, Black race (OR 0.49; 95% CI 0.26-0.91;p=0.024) and Northeast (OR 0.50; 95% CI 0.30-0.84;p=0.009) or Southern (OR 0.42; 95% CI 0.22-0.78;p=0.007) region were negatively associated with reported testing. Patients with a reported test were more likely to receive adjuvant treatment (OR 1.73; 95% CI 1.46-2.04;p<0.001). CONCLUSION: Despite the 2016 WHO guidelines, disparities in reported 1p/19q codeletion testing by geographic region persisted while new disparities in race/ethnicity were identified, which may influence oligodendroglioma and oligoastrocytoma patient management.
RESUMEN
Numerous clinical trials are being conducted in the field of spinal cord injury (SCI). These trials are typically registered on ClinicalTrials.gov. The objective of this study was to identify the characteristics of the completed SCI trials and characterize the potential factors associated with publication. ClinicalTrials.gov database was queried for all the completed trials on patients with SCI. Baseline characteristics of the completed trials were assessed. The publication status of these trials was identified using PubMed or Google Scholar. The secondary and primary outcomes reported in the publication were then compared to the outcomes registered in ClinicalTrial.gov. Multivariable logistic regression analysis was performed to determine the characteristics associated with publication status and time to publication. A total of 457 of 1,061 trials on SCI were completed. Of those, 60% were ultimately published. Trials that had received funding from sources besides the NIH, private industries, or the federal government were more likely to remain unpublished. The median time to publish was three years, with larger trials taking a longer time. The median sample size for completed trials was 30. Assessment of mismatch rates in primary outcomes of published data to registered outcomes was 8.9%. In SCI trials, outcomes registered on ClinicalTrial.gov often matched published results. Additionally, sample size and funding source play a significant role in the publication rate of these trials. Published data represents a reliable source for clinicians, researchers, and patients; efforts to curb publication bias and reporting bias are paramount for implementing evidence-based practices and ensure proper scientific conduct.

OBJECTIVE: The impact of the type of pain presentation on outcomes of spine surgery remains elusive. The aim of this study was to assess the impact of predominant symptom location (predominant arm pain vs predominant neck pain vs equal neck and arm pain) on postoperative improvement in patient-reported outcomes. METHODS: The Quality Outcomes Database cervical spine module was queried for patients undergoing 1- or 2-level anterior cervical discectomy and fusion (ACDF) for degenerative spine disease. RESULTS: A total of 9277 patients were included in the final analysis. Of these patients, 18.4% presented with predominant arm pain, 32.3% presented with predominant neck pain, and 49.3% presented with equal neck and arm pain. Patients with predominant neck pain were found to have higher (worse) 12-month Neck Disability Index (NDI) scores (coefficient 0.24, 95% CI 0.15-0.33; p < 0.0001). The three groups did not differ significantly in odds of return to work and achieving minimal clinically important difference in NDI score at the 12-month follow-up. CONCLUSIONS: Analysis from a national spine registry showed significantly lower odds of patient satisfaction and worse NDI score at 1 year after surgery for patients with predominant neck pain when compared with patients with predominant arm pain and those with equal neck and arm pain after 1- or 2-level ACDF. With regard to return to work, all three groups (arm pain, neck pain, and equal arm and neck pain) were found to be similar after multivariable analysis. The authors' results suggest that predominant pain location, especially predominant neck pain, might be a significant determinant of improvement in functional outcomes and patient satisfaction after ACDF for degenerative spine disease. In addition to confirmation of the common experience that patients with predominant neck pain have worse outcomes, the authors' findings provide potential targets for improvement in patient management for these specific populations.

BACKGROUND: The current study seeks to examine the association between chronic opioid use and postoperative outcomes for patients undergoing anterior cervical discectomy and fusion (ACDF) and posterior lumbar fusion (PLF). METHODS: The National Inpatient Sample was queried for patients with and without chronic opioid use undergoing ACDF or PLF for degenerative disc disease between 2012 and 2015 using ICD-9 diagnosis and procedure codes. Multivariable conditional logistic regression was performed to assess the association between chronic opioid use and length of stay (LOS), nonhome discharge, and hospital charge. RESULTS: A total of 391 patients undergoing ACDF and 644 patients undergoing PLF with opioid dependence were identified. On multivariable regression analysis, opioid dependence was significantly associated with an increased LOS (mean, 3.09 days vs. 2.16 days; odds ratio (OR) for prolonged LOS (>3 days), 2.11; 95% confidence interval [CI], 1.43-3.14; P < 0.001). Although on unadjusted analyses, patients with opioid dependence undergoing ACDF were found to have higher hospital charges (mean, U.S. $18,698.42 vs. $11,378.61; P < 0.001) and higher rates of nonroutine discharge (19.18% vs. 10.21%; P < 0.001), the multivariable regression analyses found no significant association between opioid dependence and odds of hospital charges >75th percentile (OR, 1.44; 95% CI, 0.84-2.47; P = 0.188) or nonroutine discharge (OR, 1.48; 95% CI, 0.93-2.34; P = 0.098). For those undergoing PLF, opioid dependence was significantly associated with increased hospital charges (mean, U.S. $37,712.98 vs. $30,475.43, P < 0.001; OR for hospital charge >75th percentile, 1.78, 95% CL, 1.23-2.58, P = 0.002), LOS (mean, 3.42 days vs. 2.30 days; OR for prolonged LOS, 1.53; 95% CI, 1.16-2.00; P = 0.003), and nonroutine discharge (46.89% vs. 36.47%; OR, 1.74; 95% CI, 1.34-2.26; P < 0.001) on both unadjusted and adjusted multivariable regression analyses. CONCLUSIONS: Our analysis using a national administrative database showed that opioid dependence may be associated with worse economic outcomes for patients undergoing ACDF and PLF.

OBJECTIVE: Optimizing patient discharge after surgery has been shown to impact patient recovery and hospital/physician workflow and to reduce healthcare costs. In the current study, the authors sought to identify risk factors for nonroutine discharge after surgery for cervical myelopathy by using a national spine registry. METHODS: The Quality Outcomes Database cervical module was queried for patients who had undergone surgery for cervical myelopathy between 2016 and 2018. Nonroutine discharge was defined as discharge to postacute care (rehabilitation), nonacute care, or another acute care hospital. A multivariable logistic regression predictive model was created using an array of demographic, clinical, operative, and patient-reported outcome characteristics. RESULTS: Of the 1114 patients identified, 11.2% (n = 125) had a nonroutine discharge. On univariate analysis, patients with a nonroutine discharge were more likely to be older (age ≥ 65 years, 70.4% vs 35.8%, p < 0.001), African American (24.8% vs 13.9%, p = 0.007), and on Medicare (75.2% vs 35.1%, p < 0.001). Among the patients younger than 65 years of age, those who had a nonroutine discharge were more likely to be unemployed (70.3% vs 36.9%, p < 0.001). Overall, patients with a nonroutine discharge were more likely to present with a motor deficit (73.6% vs 58.7%, p = 0.001) and more likely to have nonindependent ambulation (50.4% vs 14.0%, p < 0.001) at presentation. On multivariable logistic regression, factors associated with higher odds of a nonroutine discharge included African American race (vs White, OR 2.76, 95% CI 1.38-5.51, p = 0.004), Medicare coverage (vs private insurance, OR 2.14, 95% CI 1.00-4.65, p = 0.04), nonindependent ambulation at presentation (OR 2.17, 95% CI 1.17-4.02, p = 0.01), baseline modified Japanese Orthopaedic Association severe myelopathy score (0-11 vs moderate 12-14, OR 2, 95% CI 1.07-3.73, p = 0.01), and posterior surgical approach (OR 11.6, 95% CI 2.12-48, p = 0.004). Factors associated with lower odds of a nonroutine discharge included fewer operated levels (1 vs 2-3 levels, OR 0.3, 95% CI 0.1-0.96, p = 0.009) and a higher quality of life at baseline (EQ-5D score, OR 0.43, 95% CI 0.25-0.73, p = 0.001). On predictor importance analysis, baseline quality of life (EQ-5D score) was identified as the most important predictor (Wald χ2 = 9.8, p = 0.001) of a nonroutine discharge; however, after grouping variables into distinct categories, socioeconomic and demographic characteristics (age, race, gender, insurance status, employment status) were identified as the most significant drivers of nonroutine discharge (28.4% of total predictor importance). CONCLUSIONS: The study results indicate that socioeconomic and demographic characteristics including age, race, gender, insurance, and employment may be the most significant drivers of a nonroutine discharge after surgery for cervical myelopathy.
RESUMEN
BACKGROUND: Gonadotroph pituitary adenoma (Gn-PA) may rarely cause ovarian hyperstimulation syndrome, leading to infertility in women, although this remains poorly described. METHODS: We present a quantitative systematic review including 2 patients from our institutional and 48 from the literature with Gn-PA causing ovarian hyperstimulation syndrome to thoroughly describe the clinical features and therapeutic outcomes from multidisciplinary aspects. RESULTS: The patients had a mean age of 31.5 years and a mean follicle-stimulating hormone level of 14.4 IU/L. Estradiol level was high in 82% of patients, at >350 pg/mL. The mean maximal adenoma diameter was 22 mm, with a Knosp grade ≥3 in 10 patients. Abdominal surgery preceded adenoma resection in 24 patients (48%). Among 25 patients for whom extent of resection was recorded, total adenoma resection was achieved in 12. Through a mean follow-up of 25 months, adenoma recurrence was observed in 5 patients, who were treated with re-resection (n = 2), radiation (n = 2), and medical therapy followed by bilateral oophorectomy (n = 1). Medical therapies were partially effective or ineffective, and adenoma shrinkage did not follow; gonadotropin-releasing hormone agonists/antagonists were partially effective in 20% of patients (2/10), dopamine agonists in 44% (8/18), and somatostatin analogues in 50% (1/2). Four experienced swelling of tumor/ovaries after gonadotropin-releasing hormone agonists/antagonists administration. Overall, chemical remission was obtained in 26 of 28 patients, normalization of ovaries in 25 of 27, and successful pregnancy in 12 of 14. CONCLUSIONS: Adenoma resection is the main treatment, leading to reduction in ovarian size and biochemical remission, with a high likelihood of subsequent spontaneous pregnancy. Increased awareness of this rare condition may help avoid unnecessary abdominal procedures.

BACKGROUND: Intraoperative vascular injuries in the cervical spine are rare, but carry significant morbidity and mortality when they do occur. There is a need to better characterize the risk of vertebral artery injury (VAI) after posterior C1-C2 fusion. The aim of this study was to investigate the rate of VAI in patients undergoing posterior C1-C2 cervical fusion. METHODS: An electronic database search was performed to identify studies that reported rates of VAI following posterior cervical fusion at C1-C2 level. Patient-specific risk factors, surgical indication, surgical technique, and other data were collected for each study. Forest plots were created to outline the pooled ratios of VAI in the literature. RESULTS: Eleven studies with 773 patients were identified. Mean age of patients was 48.47 years (range, 6-78 years), and most patients were female (61.7%, n = 399). Trauma was the most frequent indication for surgery (18.8%, n = 146), followed by inflammatory processes affecting the vertebrae (13.2%, n = 102). The rate of VAI per patient was 2% (95% confidence interval = 1%-4%) among 773 patients, while injury rate per screw was 1% (95% confidence interval = 0%-2%) among 2238 screws placed. CONCLUSIONS: The rate of VAI after C1-C2 posterior cervical fusion was found to be 2% for each operated patient and 1% for each screw placed.
