RESUMEN
OBJECTIVE: Magnetic resonance imaging (MRI) is increasingly used to evaluate patients with diffuse traumatic brain injury (dTBI). However, the utility of early MRI is understudied. We hypothesize that early MRI patients will have increased length of stay but no changes in intracranial pressure (ICP) management or disposition. METHODS: The 2019 National Trauma Data Bank was queried for patients with dTBI and Glasgow Coma Scale score ≤8. Extra-axial and focal intra-axial hemorrhages were excluded. Clinical characteristics were controlled for. Patients with and without MRI were compared for ICP management, outcome, mortality, and disposition. A propensity score matching algorithm was used to create a 1:1 match cohort. RESULTS: In 2568 patients, MRI was less common in severe dTBI patients with clear reasons for poor examination, including bilaterally unreactive pupils or midline shift. After matching, 501 patients who underwent MRI within 1 week were compared with 501 patients without MRI. Magnetic resonance imaging patients had longer intensive care unit stays (11.6 ± 9.6 vs. 13.4 ± 9.5, p < 0.01; 95% confidence interval [95% CI], -3.03 to -0.66). There was no difference between groups in ICP monitor (23.6% vs. 27.3%; p = 0.17; 95% CI, -0.09 to 0.02) or ventriculostomy placement (13.6% vs. 13.2%, p = 0.85; 95% CI, -0.04 to 0.05) or in withdrawal of care (15.0% vs. 18.6%, p = 0.12; 95% CI, -0.08 to 0.01). MRI patients were more likely to be discharged to inpatient rehabilitation (42.9% vs. 33.5%; p < 0.01; 95% CI, 0.03-0.15) but not to home (9.4% vs. 9.0%; p = 0.83; 95% CI, -0.03 to 0.04). CONCLUSION: The decision to pursue early brain MRI may be driven by lack of obvious reasons for a patient's poor neurologic status. MRI patients had longer intensive care unit stays but no difference in rates of placement of ICP monitors or ventriculostomies or withdrawal of care. Further study is required to define the role of early MRI in dTBI patients. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

STUDY DESIGN: Retrospective matched analysis. PURPOSE: To evaluate the effect of antithrombotic drug therapy on the rates of thrombo-ischemic or bleeding events 90 days following elective spine surgery. OVERVIEW OF LITERATURE: Thrombo-ischemic and bleeding complications in patients undergoing spine surgery are major causes of morbidity. Many patients who pursue elective spine surgery are concurrently receiving antithrombotic therapy for unrelated conditions; however, at this time, the effects of preoperative antithrombotic use on postoperative bleeding and thrombosis are unclear. METHODS: Using an all-payer claims database, patients who underwent elective cervical and lumbar spine interventions between January 1, 2010, and June 30, 2018, were identified. Individuals were categorized into groups taking and not taking antithrombotics. A 1:1 analysis was constructed based on comorbidities found to be independently associated with bleeding or ischemic complications using logistic regression models. The primary outcomes were the rates of thrombo-ischemic events and bleeding complications. RESULTS: A total of 660,866 patients were eligible for inclusion. Following the matching procedure, 56,476 patient records were analyzed, with 28,238 in each group. The antithrombotic agent group had significantly greater odds of developing any 90-day thromboischemic event after surgery: deep vein thrombosis (odds ratio [OR], 3.61; 95% confidence interval [CI], 3.06-4.25), pulmonary embolism (OR, 3.93; 95% CI, 3.34-4.62), myocardial infarction (OR, 6.20; 95% CI, 5.69-6.76), and ischemic stroke (OR, 3.76; 95% CI, 3.31-4.27). In addition, the antithrombotic agent group had an increased likelihood of experiencing hematoma (OR, 1.54; 95% CI, 1.35-1.76) and need for transfusion (OR, 2.61; 95% CI, 2.29-2.96). CONCLUSIONS: Patients taking antithrombotic medications before elective surgery of the cervical and lumbar spine had increased risks of both ischemic and bleeding events. Spine surgeons should carefully consider these implications when appraising patients for surgery, given the lack of guidelines on perioperative management of antithrombotic agents.
RESUMEN
Chronic pain is one of the most common, costly, and potentially debilitating health issues facing older adults, with attributable costs exceeding $600 billion annually. The prevalence of pain in humans increases with advancing age. Yet, the contributions of sex differences, age-related chronic inflammation, and changes in neuroplasticity to the overall experience of pain are less clear, given that opposing processes in aging interact. This review article examines and summarizes pre-clinical research and clinical data on chronic pain among older adults to identify knowledge gaps and provide the base for future research and clinical practice. We provide evidence to suggest that neurodegenerative conditions engender a loss of neural plasticity involved in pain response, whereas low-grade inflammation in aging increases CNS sensitization but decreases PNS sensitivity. Insights from preclinical studies are needed to answer mechanistic questions. However, the selection of appropriate aging models presents a challenge that has resulted in conflicting data regarding pain processing and behavioral outcomes that are difficult to translate to humans.

Chronic musculoskeletal (MSK) pain remains a leading cause of disability and functional impairment among older adults and is associated with substantial societal and personal costs. Chronic pain is particularly challenging to manage in older adults because of multimorbidity, concerns about treatment-related harm, as well as older adults' beliefs about pain and its management. This narrative review presents data on nine high-quality, peer-reviewed clinical trials published primarily over the past two years that focus on MSK pain management in older adults, of which four were comprehensively reviewed. These studies address contributors to knee osteoarthritis (OA) pain (insomnia), provide evidence for digital delivery or artificial intelligence driven behavioral interventions and potentially more efficient/equally effective modes of delivering glucocorticoids for OA; each of the selected studies have potential for scalability and meaningful impact in the care of older adults.

STUDY DESIGN: Systematic review and meta-analysis. OBJECTIVE: To perform a systematic review and meta-analysis of previous studies on HbA1c in preoperative risk stratification in patients undergoing spinal procedures and provide an overview of the consensus recommendations. SUMMARY OF BACKGROUND DATA: Diabetes mellitus (DM) and hyperglycemia have been shown to be independent risk factors for increased surgical complications. Glycated Hemoglobin A1C (HbA1c), a surrogate for long term glycemic control, is an important preoperative parameter that may be optimized to reduce surgical complications and improve patient-reported outcomes. However, comprehensive systematic reviews on preoperative HbA1c and postoperative outcomes in spine surgery have been limited. METHODS: We systematically searched PubMed, EMBASE, Scopus, and Web-of-Science for English-language studies from inception through April 5 th , 2022, including references of eligible articles. The search was conducted according to PRISMA guidelines. Only studies in patients undergoing spine surgery with preoperative HbA1c values and postoperative outcomes available were included. RESULTS: A total of 22 articles (18 retrospective cohort studies, 4 prospective observational studies) were identified with level of evidence III or greater. The majority of studies (n=17) found that elevated preoperative HbA1c was associated with inferior outcomes or increased risk of complications. Random-effect meta-analysis demonstrated that patients with preoperative HbA1c >8.0% had increased risk(s) of postoperative complications (RR: 1.85, 95% CI: [1.48, 2.31], P <0.01) and that patients with surgical site infection (SSI) had higher preoperative HbA1c (Mean Difference: 1.49%, 95% CI: [0.11, 2.88], P =0.03). CONCLUSION: The findings of this study suggest that HbA1c >8.0% is associated with an increased risk of complications. HbA1c was higher by 1.49% on average among patients with SSI when compared to patients who did not experience SSI. These results suggest that elevated HbA1c is associated with less favorable outcomes following spine surgery. LEVEL OF EVIDENCE: IV.

STUDY DESIGN: Systematic review and Meta-analysis. OBJECTIVE: To compare outcomes and complications profile of laminectomy alone versus laminectomy and fusion for the treatment of degenerative lumbar spondylolisthesis (DLS). SUMMARY OF BACKGROUND DATA: Degenerative lumbar spondylolisthesis is a common cause of back pain and functional impairment. DLS is associated with high monetary (up to $100 billion annually in the US) and nonmonetary societal and personal costs. While nonoperative management remains the first-line treatment for DLS, decompressive laminectomy with or without fusion is indicated for the treatment-resistant disease. METHODS: We systematically searched PubMed and EMBASE for RCTs and cohort studies from inception through April 14, 2022. Data were pooled using random-effects meta-analysis. The risk of bias was assessed using the Joanna Briggs Institute risk of bias tool. We generated odds ratio and standard mean difference estimates for select parameters. RESULTS: A total of 23 manuscripts were included (n=90,996 patients). Complication rates were higher in patients undergoing laminectomy and fusion compared with laminectomy alone (OR: 1.55, P <0.001). Rates of reoperation were similar between both groups (OR: 0.67, P =0.10). Laminectomy with fusion was associated with a longer duration of surgery (Standard Mean Difference: 2.60, P =0.04) and a longer hospital stay (2.16, P =0.01). Compared with laminectomy alone, the extent of functional improvement in pain and disability was superior in the laminectomy and fusion cohort. Laminectomy with fusion had a greater mean change in ODI (-0.38, P <0.01) compared with laminectomy alone. Laminectomy with fusion was associated with a greater mean change in NRS leg score (-0.11, P =0.04) and NRS back score (-0.45, P <0.01). CONCLUSION: Compared with laminectomy alone, laminectomy with fusion is associated with greater postoperative improvement in pain and disability, albeit with a longer duration of surgery and hospital stay.

OBJECTIVE: Obesity is a major health care concern in the United States and is associated with high rates of postoperative complications after spine surgery. Obese patients assert that weight reduction is not possible unless spine surgery first relieves their pain and concomitant immobility. We describe the post-spine surgery effects on patient weight, with an emphasis on obesity. METHODS: PubMed, EMBASE, Scopus, Web of Science, and Cochrane databases were systematically searched according to the PRISMA guidelines. The search included indexed terms and text words from database inception to the date of the search (15 April 2022). Studies chosen for inclusion had to have data reporting on pre- and postoperative patient weight after spine surgery. Data and estimates were pooled using the Mantel-Haenszel method for random-effects meta-analysis. RESULTS: Eight articles encompassing 7 retrospective and 1 prospective cohort were identified. A random effects model analysis demonstrated that overweight and obese patients (body mass index [BMI], >25 kg/m2) had increased odds of clinically significant weight loss after lumbar spine surgery compared with non-obese patients (odds ratio, 1.63; 95% confidence interval, 1.43-1.86, P < 0.0001). There was no significant difference in the raw weight change between BMI categories (mean difference, -0.67 kg, 95% confidence interval, -4.71 to 3.37 kg, P = 0.7463). CONCLUSIONS: Compared with non-obese patients (BMI, <25 kg/m2), overweight and obese patients have higher odds of clinically significant weight loss after lumbar spine surgery. No difference in pre-operative and post-operative weight was found, although statistical power was lacking in this analysis. Randomized controlled trials and additional prospective cohorts are needed to further validate these findings.

STUDY DESIGN: Systematic review and meta-analysis. OBJECTIVE: To perform a systematic review and meta-analysis investigating the rate of adverse events after spine surgery in patients who underwent bariatric surgery (BS). SUMMARY OF BACKGROUND DATA: Obesity is an established risk factor for postoperative complications after spine surgery. BS has been associated with improvements in health in patients with severe obesity. However, it is not known whether undergoing BS before spine surgery is associated with reduced adverse outcomes. MATERIALS AND METHODS: PubMed, EMBASE, Scopus, and Web-of-Science were systematically searched according to "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" guidelines. The search included indexed terms and text words from database inception to the date of the search (May 27, 2022). Data and estimates were pooled using the Mantel-Haenszel method for random-effects meta-analysis. Risk of bias was assessed using the Joanna Briggs Institute risk of bias tool. The primary outcome was an all-cause complication rate after surgery. Relative risks for surgical and medical complications were assessed. RESULTS: A total of 4 studies comprising 177,273 patients were included. The pooled analysis demonstrated that the all-cause medical complication rate after spine surgery was lower in patients undergoing BS (relative risk: 0.54, 95% CI: 0.39, 0.74, P < 0.01). There was no difference in rates of surgical complications and 30-day hospital readmission rates between the cohort undergoing BS before spine surgery and the cohort that did not. CONCLUSION: These analyses suggest that obese patients undergoing BS before spine surgery have significantly lower adverse event rates. Future prospective studies are needed to corroborate these findings. LEVEL OF EVIDENCE: 4.

PURPOSE: The purpose of this study was to characterize the sagittal spine in AIS patients with double major curves fused into the lumbar spine to determine the effects of posterior spinal fusion and instrumentation (PSFI) on global and segmental lumbar sagittal parameters. METHODS: A consecutive series of AIS patients undergoing a PSFI from 2012 to 2017 having Lenke 3, 4 or 6 curves were analyzed. Sagittal parameters included pelvic incidence (PI), lumbar lordosis (LL), and segmental lordosis were measured. The difference in segmental lumbar lordosis between the preoperative, 6-week, and 2-year radiographs was analyzed and correlated to outcomes using SRS-30 patient questionnaires. RESULTS: Seventy-seven patients had improvement in their coronal Cobb from 67.3 ± 11.8° to 25.43 ± 10.7° (66.4%) at 2 years. There was no change in thoracic kyphosis (23.0 ± 13.4° to 20.3 ± 7.8°) and pelvic incidence (49.9 ± 13.4° to 51.1 ± 15.7°) from preoperative to 2 years (p > 0.05) while lumbar lordosis increased from 57.6 ± 12.4° to 61.4° ± 12.3° (p = 0.002). Segmental lumbar analysis showed increased (+) lordosis at each instrumented level when comparing the preoperative and 2-year films for: T12-L1 (+ 3.24°, p < 0.001), L1-L2 (+ 5.70°, p < 0.001), and L2-L3 (+ 1.70°, p < 0.001). Loss (-) of lordosis was noted at every level below the LIV: L3-L4 (- 1.70°, p < 0.001), L4-L5 (- 3.52°, p < 0.001), L5-S1 (- 1.98°, p = 0.02). Preoperative LL of L4-S1 comprised 70 ± 16% of the global LL compared to 56 ± 12%, at 2 years (p < 0.001). Changes in sagittal measurements did not correlate with SRS outcome scores at two-year follow-up. CONCLUSION: When performing PSFI for double major scoliosis, global SVA was maintained at 2 years, however, overall lumbar lordosis increased due to an increased lordosis in the instrumented segments and a smaller decrease in lordosis below the LIV. Surgeons should be wary of the tendency to create instrumented lumbar lordosis with a compensatory loss of lordosis below LIV which may be a set-up for poor long-term outcomes in adulthood.

OBJECTIVE: The coprevalence of age-related comorbidities such as cognitive impairment and spinal disorders is increasing. No studies to date have assessed the postoperative spine surgery outcomes of patients with mild cognitive impairment (MCI) or severe cognitive impairment (dementia) compared with those without preexisting cognitive impairment. METHODS: Using all-payer claims database, 235,123 persons undergoing either cervical or lumbar spine procedures between January 2010 and October 2020 were identified. Exact 1:1:1 matching based on baseline patient demographics and comorbidities was used to create a dementia group, MCI group, and control group without MCI/dementia (n = 3636). The primary outcome was the rate of any 30-day major postoperative complications. Secondary outcomes included the rates of revision surgery, readmission rates within 30 days, and health care costs within 1 year postoperatively. RESULTS: Compared with the control group, patients with dementia had an 8-fold and 5.4-fold increase in all-cause 30-day complications after undergoing cervical and lumbar spine procedures, respectively. Similarly, patients with MCI had a 3.1-fold and 2.2-fold increase in all-cause 30-day complications, respectively. Patients with either MCI or dementia had increased rates of pneumonia and urinary tract infection after either spine procedure compared with control (P < 0.01). Odds of revision surgery were increased in the lumbar surgery cohort for dementia (3.43; 95% confidence interval, 1.69-6.95) and for MCI (2.41; 95% confidence interval, 1.14-5.05). CONCLUSIONS: This is the first study to characterize the postoperative complications profile of patients with preexisting dementia or MCI undergoing cervical and lumbar spine surgery. Both dementia and MCI are associated with increased postoperative complications within 30 days.

BACKGROUND CONTEXT: Navigated and robotic pedicle screw placement systems have been developed to improve the accuracy of screw placement. However, the literature comparing the safety and accuracy of robotic and navigated screw placement with fluoroscopic freehand screw placement in thoracolumbar spine surgery has been limited. PURPOSE: To perform a systematic review and meta-analysis of randomized control trials that compared the accuracy and safety profiles of robotic and navigated pedicle screws with fluoroscopic freehand pedicle screws. STUDY DESIGN/SETTING: Systematic review and meta-analysis PATIENT SAMPLE: Only randomized controlled trials comparing robotic-assisted or navigated pedicle screws placement with freehand pedicle screw placement in the thoracolumbar spine were included. OUTCOME MEASURES: Odds ratio (OR) estimates for screw accuracy according to the Gertzbein-Robbins scale and relative risk (RR) for various surgical complications. METHODS: We systematically searched PubMed and EMBASE for English-language studies from inception through April 7, 2022, including references of eligible articles. The search was conducted according to PRISMA guidelines. Two reviewers conducted a full abstraction of all data, and one reviewer verified accuracy. Information was extracted on study design, quality, bias, participants, and risk estimates. Data and estimates were pooled using the Mantel-Haenszel method for random-effects meta-analysis. RESULTS: A total of 14 papers encompassing 12 randomized controlled trials were identified (n=892 patients, 4,046 screws). The pooled analysis demonstrated that robotic and navigated pedicle screw placement techniques were associated with higher odds of screw accuracy (OR 2.66, 95% CI 1.24-5.72, p=.01). Robotic and navigated screw placement was associated with a lower risk of facet joint violations (RR 0.09, 95% CI 0.02-0.38, p<.01) and major complications (RR 0.31, 95% CI 0.11-0.84, p=.02). There were no observed differences between groups in nerve root injury (RR 0.50, 95% CI 0.11-2.30, p=.37), or return to operating room for screw revision (RR 0.28, 95% CI 0.07-1.13, p=.07). CONCLUSIONS: These estimates suggest that robotic and navigated screw placement techniques are associated with higher odds of screw accuracy and superior safety profile compared with fluoroscopic freehand techniques. Additional randomized controlled trials will be needed to further validate these findings.

BACKGROUND: The purpose of this study is to describe curve characteristics and postoperative outcomes in patients undergoing spinal fusion (SF) to treat thoracogenic scoliosis related to sternotomy and/or thoracotomy as a growing child. METHODS: A retrospective review of electronic medical records of all patients with Post-Chest Incision scoliosis treated with SF was performed at 2 tertiary care pediatric institutions over a 19-year period. Curve characteristics, inpatient, and outpatient postoperative outcomes are reported. RESULTS: Thirty-nine patients (62% female) were identified. Eighteen had sternotomy alone, 14 had thoracotomy alone, and 7 had both. Mean age at the time of first chest wall surgery was 2.5 years (range: 1.0 d to 14.2 y). Eighty-five percent of patients had a main thoracic curve (mean major curve angle 72 degrees, range: 40 to 116 degrees) and 15% had a main lumbar curve (mean major curve angle 76 degrees, range: 59 to 83 degrees). Mean thoracic kyphosis was 40 degrees (range: 4 to 84 degrees). Mean age at the time of SF was 14 years (range: 8.2 to 19.9 y). Thirty-six patients had posterior fusions and 3 had combined anterior/posterior. Mean coronal curve correction measured at the first postoperative encounter was 53% (range: 9% to 78%). There were 5 (13%) neuromonitoring alerts and 2 (5%) patients with transient neurological deficits. Mean length of hospital stay was 9±13 days. At an average follow-up time of 3.1±2.4 years, 17 complications (10 medical and 7 surgical) were noted in 9 patients for an overall complication rate of 23%. There was 1 spinal reoperation in the cohort. 2/17 (12%) complications were Clavien-Dindo-Sink class III and 5/17 (29%) were class IV. CONCLUSION: Kyphotic thoracic curves predominate in patients with Post-Chest Incision scoliosis undergoing SF. Although good coronal and sagittal plane deformity can be expected after a fusion procedure, postoperative complications are not uncommon in medically complex patients, often necessitating longer postoperative stays. LEVEL OF EVIDENCE: Level III.

STUDY DESIGN: Retrospective cohort. BACKGROUND: Over 44 million adults are estimated to have either osteoporosis or osteopenia. Adult spinal deformity (ASD) is estimated to affect between 32 and 68% of the elderly population. OBJECTIVE: Retrospective investigation comparing rates of postoperative complications following thoracolumbar scoliosis surgery in patients with normal bone mineral density (BMD) to those with osteopenia or osteoporosis in addition to analyzing the effects of pretreatment with anti-osteoporotic medications in patients with low BMD. METHODS: Using administrative database of Humana beneficiaries, ICD-9 and ICD-10 diagnosis codes were used to identify ASD patients undergoing multilevel thoracolumbar fusions between 2007 and 2017. RESULTS: The propensity matched population analyzed in this study contained 1044 patients equally represented by those with a history of osteopenia, osteoporosis, or normal BMD. Osteopenia and osteoporosis were associated with increased odds of revision surgery (OR 2.01 95% CI 1.36-2.96 and OR 1.57, 95% CI 1.05-2.35), respectively. Similarly, there was an almost twofold increased odds of proximal and distal junctional kyphosis in patients with osteopenia and osteoporosis (OR 1.95, 95% CI 1.40-2.74 and OR 1.88, 95% CI 1.34-2.64), respectively. A total of 258 (37.1%) patients with osteoporosis were pretreated with anti-osteoporotic medications and there was no statistically significant decrease in odds of proximal or distal junctional kyphosis or revision surgery in these patients. CONCLUSION: Patients with ASD undergoing multilevel thoracolumbar fusion surgery have significantly higher rates of postoperative pseudarthrosis, proximal and distal junctional kyphosis, and revision surgery rates compared to patients with normal BMD.

BACKGROUND: While several studies explore the impact of smoking tobacco on spinal fusion outcomes, there is a paucity of literature on the influence of modern smoking cessation therapies on such outcomes in patients undergoing anterior cervical discectomy and fusion (ACDF). OBJECTIVE: Our study explores the outcomes of single-level ACDF surgery in nonsmokers, active smokers, and smokers undergoing cessation therapy. METHODS: MARINER30, an all-payer claims database, was utilized to identify patients undergoing single-level ACDF between 2010 and 2019. The primary outcomes were the rates of composite surgical complications, dysphagia, hematoma, symptomatic pseudarthrosis, instrumentation removal, need for revision surgery, and all-cause readmission rates within 30 and 90-days. RESULTS: The matched population consisted of 5769 patients undergoing single-level ACDF with 1923 (33.33%) in each of the following groups: (1) nonsmokers; (2) active smokers; and (3) patients undergoing smoking cessation therapy. Nonsmokers had significantly lower rates of composite surgical complications (3.74% vs 13.05% vs 15.08%), revision surgery (4.06% vs 20.07% vs 22.88%), instrumentation removal (0.83% vs. 2.08% vs. 2.76%), and dysphagia (0.36% vs 0.99% vs 0.62%) when compared to patients in the active smoking and smoking cessation groups, respectively. CONCLUSION: Patients using smoking cessation therapy were more likely to develop postoperative dysphagia and undergo revision surgery when compared to their actively smoking counterparts. While surgeons routinely recommend smoking cessation prior to surgery, the effects of smoking cessation therapies on surgical outcomes are not well characterized.

OBJECTIVE: We sought to investigate the effect of preoperative polypharmacy (PP) on the 90-day all-cause readmission rate in older adults undergoing corrective surgery for adult spinal deformity. METHODS: Older adults with a diagnosis of adult spinal deformity undergoing spinal surgery at a quaternary medical center from January 2016 to March 2019 were enrolled in this study. Patients were dichotomized into 2 groups stratified by the number of preoperative prescription medications, with PP defined as 5 or more prescription medications. The primary outcome measure was 90-day all-cause readmission rate. Secondary outcomes included postoperative changes in health-related quality of life measures. RESULTS: Among 161 patients (mean [standard deviation], 69.59 [8.79] years), 97 patients were included in the PP cohort and 64 in the nonpolypharmacy (non-PP) cohort. Both groups were balanced at baseline. Duration of hospital stay (5.82 [1.93] vs. 6.50 [4.00] days), mean number of fusion levels, and duration of surgery were statistically similar between both groups (P > 0.05). There was no difference in the proportion of patients discharged directly home (31.25% vs. 40.42%, P = 0.36). The 90-day all-cause readmission rate was 3-fold higher in the PP cohort compared with the non-PP cohort. After adjusting for preoperative patient optimization, American Society of Anesthesiologists grade, surgical invasiveness, smoking, depression, and baseline functional disability, older adults with PP had a 9.79 increased odds of 90-day all-cause hospital readmission (P = 0.04). Changes in health-related quality of life measures were similar between both groups. CONCLUSION: This study's findings indicate that despite preoperative optimization, older adults exposed to polypharmacy are at a significantly increased risk of hospital readmission within 90 days of surgery.

BACKGROUND: Diversity, equity, and inclusion within the healthcare workforce are conducive to providing culturally competent care. However, few existing studies have assessed the level of racial and ethnic diversity among resident physicians and residency applicants. Our objective was to provide a comparative analysis of the trends in racial and ethnic representation within different subspecialties in medicine. METHODS: Using data from the American Association of Medical Colleges and the Journal of the American Medical Association, we evaluated the racial and ethnic identification of residency applicants and current residents in 9 procedural-focused specialties from 2005 to 2019 and performed a descriptive analysis to compare the different levels of racial and ethnic diversity in these specialties. RESULTS: Among the specialties analyzed during the study period, neurosurgery had the greatest magnitude of differences between Black/African-American residency applicants and current residents. The percentage of Black/African-American applicants was 92% greater than that of Black/African-American residents (10% of applicants vs. 5.2% of residents). In contrast, the percentage of White neurosurgery residents was 17.6% greater than that of White neurosurgery applicants (53.9% of applicants vs. 63.4% of residents). Similar trends were noted in all the specialties evaluated. Obstetrics and gynecology demonstrated the least disparity between Black/African-American applicants and residents (13.7% of applicants vs. 10.2% of residents; 35.4% difference). Hispanic and Asian representation varied widely between specialties. CONCLUSIONS: Among the surveyed specialties, neurosurgery demonstrated the greatest disparity between the percentage of Black/African-American residency applicants and current residents. To further drive progress in this domain, we advocate for a series of initiatives designed to increase underrepresented minority participation in neurosurgery practice and scholarship.

OBJECTIVE: While there are several reports on the impact of smoking tobacco on spinal fusion outcomes, there is minimal literature on the influence of modern smoking cessation therapies on such outcomes. Our study explores the outcomes of single-level lumbar fusion surgery in active smokers and in smokers undergoing recent cessation therapy. METHODS: MARINER30, an all-payer claims database, was utilized to identify patients undergoing single-level lumbar fusions between 2010 and 2019. The primary outcomes were the rates of any complication, symptomatic pseudarthrosis, need for revision surgery, and all-cause readmission within 30 and 90 days. RESULTS: The exact matched population analyzed in this study contained 31,935 patients undergoing single-level lumbar fusion with 10,645 (33%) in each of the following groups: (1) active smokers; (2) patients on smoking cessation therapy; and (3) those without any smoking history. Patients undergoing smoking cessation therapy have reduced odds of developing any complication following surgery (odds ratio 0.86, 95% confidence interval 0.80-0.93) when compared with actively smoking patients. Nonsmokers and patients on cessation therapy had a significantly lower rate of any complication compared with the smoking group (9.5% vs. 17% vs. 19%, respectively). CONCLUSIONS: When compared with active smoking, preoperative smoking cessation therapy within 90 days of surgery decreases the likelihood of all-cause postoperative complications. However, there were no between-group differences in the likelihood of pseudarthrosis, revision surgery, or readmission within 90 days.

BACKGROUND: The purpose of this study was to investigate whether presence of an infolded limbus on hip arthrogram at index closed reduction was associated with increased residual dysplasia or secondary surgery. METHODS: We retrospectively reviewed all patients who underwent closed reduction for dysplasia of the hip with a minimum 2-year follow-up between 1980 and 2016. Demographic data was obtained including the age at reduction and severity of dislocation based on the International Hip Dysplasia Institute (IHDI) classification. Arthrograms performed at time of closed reduction were separately reviewed by 3 fellowship-trained pediatric orthopaedic surgeons to evaluate for an infolded limbus. The primary radiographic outcome was acetabular indices at 2 and 4 years postreduction. We also assessed the presence of avascular necrosis and rate of secondary reconstructive surgery for residual dysplasia. RESULTS: A total of 182 hips in 165 patients underwent closed reduction at a mean age of 9.8±4.5 mo and were followed a mean of 9.0±4.9 y. An infolded limbus was identified in 20.3% (37/182) hips with substantial agreement among the 3 graders (Fleiss κ=0.75). The frequency of labral infolding increased with the severity of dislocation (8.8%% of IHDI II, 26.7% IHDI III, and 25.0% of IHDI IV hips; P=0.03). Hips with infolded limbus were older at reduction (12.4±5.3 vs. 9.2±5.8 mo, P=0.001). The mean acetabular index was higher in hips with infolded limbus than hips without at 2 years postreduction (34.8±4.8 vs. 32.6±5.8 degrees, respectively; P=0.04). However, multivariate analysis revealed that only the severity of dislocation predicted dysplasia at 2 years postreduction. No significant difference in acetabular index was seen at 4 years postreduction (27.2±7.4 vs. 25.4±6.5 degrees, P=0.24). There was no difference in avascular necrosis between groups (P=0.74). There was no difference in rate of secondary surgery between hips with labral infolding and those without (35% vs. 30%, respectively; P=0.52). CONCLUSIONS: An infolded limbus was more common in older patients with more severe dislocations. However, it is not associated with increased residual dysplasia or secondary surgery and may have limited utility in decision-making during closed reduction. LEVEL OF EVIDENCE: Level II-prognostic study.

OBJECTIVE: Methods of reducing complications in individuals electing to undergo anterior cervical discectomy and fusion (ACDF) rely upon understanding at-risk patient populations, among other factors. This study aims to investigate the interplay between social determinants of health (SDOH) and postoperative complication rates, length of stay, revision surgery, and rates of postoperative readmission at 30 and 90 days in individuals electing to have single-level ACDF. METHODS: Using MARINER30, a database that contains claims information from all payers, patients were identified who underwent single-level ACDF between 2010 and 2019. Identification of patients experiencing disparities in 1 of 6 categories of SDOH was completed using ICD-9 and ICD-10 (International Classifications of Diseases, Ninth and Tenth Revisions) codes. The population was propensity matched into 2 cohorts based on comorbidity status: those with SDOH versus those without. RESULTS: A total of 10,030 patients were analyzed; there were 5015 (50.0%) in each cohort. The rates of any postoperative complication (12.0% vs 4.6%, p < 0.001); pseudarthrosis (3.4% vs 2.6%, p = 0.017); instrumentation removal (1.8% vs 1.2%, p = 0.033); length of stay (2.54 ± 5.9 days vs 2.08 ± 5.07 days, p < 0.001 [mean ± SD]); and revision surgery (9.7% vs 4.2%, p < 0.001) were higher in the SDOH group compared to patients without SDOH, respectively. Patients with any SDOH had higher odds of perioperative complications (OR 2.8, 95% CI 2.43-3.33), pseudarthrosis (OR 1.3, 95% CI 1.06-1.68), revision surgery (OR 2.4, 95% CI 2.04-2.85), and instrumentation removal (OR 1.4, 95% CI 1.04-2.00). CONCLUSIONS: In patients who underwent single-level ACDF, there is an association between SDOH and higher complication rates, longer stay, increased need for instrumentation removal, and likelihood of revision surgery.
RESUMEN
STUDY DESIGN: Retrospective. OBJECTIVE: To investigate the prevalence of decisional regret among older adults undergoing surgery for adult spinal deformity (ASD). SUMMARY OF BACKGROUND DATA: Among older adults (≥65âyears old), ASD is a leading cause of disability, with a population prevalence of 60% to 70%. While surgery is beneficial and results in functional improvement, in over 20% of older adults outcomes from surgery are less desirable. METHODS: Older adults with ASD who underwent spinal surgery at a quaternary medical center from January 1, 2016 to March 1, 2019, were enrolled in this study. Patients were categorized into medium/high or low-decisional regret cohorts based on their responses to the Ottawa decision regret questionnaire. Decisional regret assessments were completed 24âmonths after surgery. The primary outcome measure was prevalence of decisional regret after surgery. Factors associated with high decisional regret were analyzed by multivariate logistic regression. RESULTS: A total of 155 patients (mean age, 69.5 yrs) met the study inclusion criteria. Overall, 80% agreed that having surgery was the right decision for them, and 77% would make the same choice in future. A total of 21% regretted the choice that they made, and 21% responded that surgery caused them harm. Comparing patient cohorts reporting medium/high- versus low-decisional regret, there were no differences in baseline demographics, comorbidities, invasiveness of surgery, length of stay, discharge disposition, or extent of functional improvement 12-months after surgery. After adjusting for sex, American Society of Anesthesiologists score, invasiveness of surgery, and presence of a postoperative complication, older adults with preoperative depression had a 4.0 fold increased odds of high-decisional regret (Pâ =â0.04). Change in health related quality of life measures were similar between all groups at 12-months after surgery. CONCLUSION: While the majority of older adults were appropriately counseled and satisfied with their decision, one-in-five older adults regret their decision to undergo surgery. Preoperative depression was associated with medium/high decisional regret on multivariate analysis.Level of Evidence: 4.
