RESUMO
The provision of specialized spine care in Nigeria presents a pressing challenge amid limited resources and geographical disparities. This correspondence offers a comprehensive roadmap for improving spine surgery and care within the country. We examine the current state of spinal health infrastructure, highlighting barriers such as limited access to specialists and facilities, particularly in rural areas, and financial constraints for patients. Innovations in spinal treatment, including the adoption of minimally invasive techniques and advancements in surgical modalities, are discussed alongside persistent challenges such as disparities in access and equipment costs. Training and education of spine surgeons emerge as critical areas requiring attention, with a shortage of qualified professionals exacerbated by inadequate training programs and resource constraints. We advocate for fostering local and international collaborations to address these gaps, emphasizing the role of partnerships in capacity building and knowledge exchange. Additionally, we explore the potential of public-private partnerships and investments to enhance the Nigerian spine healthcare system, calling for strategic initiatives to modernize infrastructure and improve accessibility. Finally, we propose a strategic blueprint encompassing infrastructure enhancement, training programs, research initiatives, policy advocacy, and public awareness campaigns. Through concerted efforts from local stakeholders and international partners, we envision a future where spine care in Nigeria is comprehensive, accessible, and of high quality, leading to improved health outcomes and a higher quality of life for those affected by spinal conditions.

BACKGROUND: Nutritional assessment tools are used to predict outcomes in cancer. However, their utility in patients undergoing spinal surgery is unclear. This review examined if prognostic nutritional index (PNI), controlling nutritional status (CONUT), and geriatric nutritional risk index (GNRI) can predict adverse events after spinal surgeries. METHODS: PubMed, CENTRAL, Scopus, and Embase were screened by two reviewers for relevant studies up to 26th January 2024. The primary outcome of interest was total adverse events after spinal surgery. Secondary outcomes were surgical site infections (SSI) and mortality. RESULTS: 14 studies were included. Meta-analysis showed that while reduced PNI was not associated with an increased risk of SSI there was a significant association between PNI and higher risk of adverse events. Meta-analysis showed that high CONUT was not associated with an increased risk of complications after spinal surgeries. Pooled analysis showed that low GNRI was associated with an increased risk of both SSI and adverse events. Data on mortality was scarce. CONCLUSIONS: The PNI and GNRI can predict adverse outcomes after spinal surgeries. Limited data shows that high CONUT is also associated with a non-significant increased risk of adverse outcomes. High GNRI was predictive of an increased risk of SSI. Data on mortality is too scarce for strong conclusions.

PURPOSE: Postoperative physical therapy (PT) is a cornerstone of orthopedic and musculoskeletal rehabilitation, proven to provide various positive clinical benefits. However, there is a paucity of literature evaluating the utility of preoperative rehabilitation specific to spine surgery. Thus, this review article aims to provide an overview of previously published studies discussing the efficacy of preoperative rehabilitation programs and its role in spinal surgery. Special emphasis was given to preoperative frailty assessments, physical performance tests, interventional strategies, feasibility, and future directions. METHODS: We performed a literature review using PubMed, Google Scholar, EMBASE, and PubMed Central (PMC) using directed search terms. Articles that examined preoperative rehabilitation in adult spine surgery were compiled for this review. Prehabilitation programs focused on exercise, flexibility, and behavioral modifications have been shown to significantly improve pain levels and functional strength assessments in patients undergoing elective spine surgery. In addition, studies suggest that these programs may also decrease hospital stays, return to work time, and overall direct health care expenditure costs. Screening tools such as the FRAIL scale can be used to assess frailty while physical function tests like the timed-up-and go (TUGT), 5 repetition sit-to-stand test (5R-STST), and hand grip strength (HGS) can help identify patients who would most benefit from prehabilitation. CONCLUSIONS: This review illustrates that prehabilitation programs have the potential to increase quality of life, improve physical function and activity levels, and decrease pain, hospital stays, return to work time, and overall direct costs. However, there is a paucity of literature in this field that requires further study and investigation.

PURPOSE: Barbed sutures are tissue control devices that can reduce operating room time and costs. We analyzed the utility of barbed sutures in posterior spinal surgery in order to prove non-inferiority to conventional methods for wound closure. METHODS: A cohort of patients undergoing elective posterior spinal surgery in which barbed (prospective) versus conventional sutures (retrospective) were used was analyzed. The primary endpoint was the occurrence of wound healing complications or the need for surgical revision. Secondary endpoints included postoperative stay, readmission rate, and duration and cost of wound closure. RESULT: A total of 483 patients participated in the study, 183 in the Barbed group and 300 in the Conventional group. Wound dehiscence or seroma occurred in 3.8% and 2.7% of the Barbed and Conventional groups, respectively (p = 0.6588). Both superficial (1.6% versus 4.0%, P = 0.2378) and deep infections (2.7% versus 4.7%, p = 0.4124) occurred similarly in both groups. Overall, the rate of re-intervention due to wound healing problems was also similar (4.9% versus 5.3%, p = 0.9906), as well as, total median hospital stay, postoperative stay and 30-day re-admission rates. The average duration of wound closure (1.66 versus 4.16 min per level operated, p < 0.0001) strongly favored the Barbed group. The mean cost of wound closure per patient was higher in the Barbed group (43.23 versus 22.67 , p < 0.0001). CONCLUSIONS: In elective posterior spinal procedures, the use of barbed sutures significantly reduced the duration of wound closure. The wound healing process was not hindered and the added cost related to the suture material was small.

BACKGROUND: Without clear signs of infection, spinal implant failure is attributed to mechanical overloads and aseptic loosening. However, how low-grade infections contribute to seemingly aseptic implant failure is unclear. PURPOSE: The systematic review examined unexpected positive cultures (UPCs) in revision spine surgery regarding prevalence, isolated pathogens, risk factors, and strategies to reduce infection among asymptomatic patients undergoing revision spine surgery. METHODS: We followed the PRISMA guidelines and searched four main databases (PubMed, EMBASE, SCOPUS, Web of Science) comprehensively until January 2023 for articles reporting UPC after presumed aseptic adult revision spine surgery. The UPC rates were pooled, and risk factors were compared with the culture-negative control group and represented as odds ratio (OR) or mean difference (MD). RESULTS: Fifteen studies of 1057 individuals were included in two groups: culture-positive or UPCs (n = 317) and culture-negative or control (n = 740). The overall UPC prevalence was 33.2% (317/1057, range: 0 to 53%, 95% CI = 30.2%-36.4%), and Cutibacterium acnes (43.0%, 95% CI = 37.4%-48.8%), Coagulase-negative Staphylococci (CoNS), (39.5%, 95% CI = 33.2%-46.2%), and Staphylococcus species in general (49.5%, 95%CI = 43.7%-55.4%) were reported the most common isolated microbes. 16.1% of the UPCs were polymicrobial. Risk factors associated with UPC rates were female sex (OR = 2.62, 95%CI = 1.76-3.90, P < 0.001), screw loosening (OR = 4.43, 95%CI = 1.31-15.02, P = 0.02), number of operated levels (MD = 0.77, 95%CI = 0.33-1.22, P = 0.0007), and shorter time since index surgery (MD = - 8.57 months, 95%CI = - 14.76, -2.39, P = 0.02). CONCLUSIONS: One-third of patients undergoing spine revision surgery revealed UPC in this study. Each UPC pathogen interpretation and antibiotic use decision should be interpreted case by case. LEVEL OF EVIDENCE: IV.

INTRODUCTION AND OBJECTIVE: Constipation is a common complication following spinal surgery that can result in distension, abdominal pain, infection, and even intestinal perforation. This study reports on an evidence-based implementation project to reduce the incidence of constipation in spinal surgery wards. METHODS: The project was conducted in the spinal surgery ward of a general tertiary hospital in Changsha City, China, from March to August 2022. We used the JBI Implementation Framework and the JBI Model of Evidence-Based Healthcare for audits and feedback. Data were collected and analyzed using JBI's Practical Application of Clinical Evidence System (PACES) software. Seven audit criteria were developed based on the best practice recommendations summarized by JBI. A baseline audit was conducted with 20 nurses and 50 patients in the spinal surgery ward, and a follow-up audit was conducted using the same sample size and setting. RESULTS: The baseline audit revealed compliance below 46% for five of the seven criteria. Strategies developed to address poor compliance included educating nurses and patients, developing a post-operative constipation risk assessment sheet, organizing stakeholder focus group meetings, establishing a constipation management routine, and effective empowerment of nurses. The follow-up audit showed positive compliance results, with the highest rate for Criterion 7 (100%) and the greatest increase for Criterion 2 (from 0% to 78%). Furthermore, the incidence of post-operative constipation decreased from 48% to 16%. CONCLUSION: The project improved compliance with audit criteria, reduced the incidence of constipation, and enhanced the efficiency of quality management in the spinal surgery ward.

BACKGROUND: Risk assessment is critically important in elective and high-risk interventions, particularly spine surgery. This narrative review describes the evolution of risk assessment from the earliest instruments focused on general surgical risk stratification, to more accurate and spine-specific risk calculators that quantified risk, to the current era of big data. METHODS: The PubMed and SCOPUS databases were queried on October 11, 2023 using search terms to identify risk assessment tools (RATs) in spine surgery. A total of 108 manuscripts were included after screening with full-text review using the following inclusion criteria: 1) study population of adult spine surgical patients, 2) studies describing validation and subsequent performance of preoperative RATs, and 3) studies published in English. RESULTS: Early RATs provided stratified patients into broad categories and allowed for improved communication between physicians. Subsequent risk calculators attempted to quantify risk by estimating general outcomes such as mortality, but then evolved to estimate spine-specific surgical complications. The integration of novel concepts such as invasiveness, frailty, genetic biomarkers, and sarcopenia led to the development of more sophisticated predictive models that estimate the risk of spine-specific complications and long-term outcomes. CONCLUSIONS: RATs have undergone a transformative shift from generalized risk stratification to quantitative predictive models. The next generation of tools will likely involve integration of radiographic and genetic biomarkers, machine learning, and artificial intelligence to improve the accuracy of these models and better inform patients, surgeons, and payers.

BACKGROUND: As of 2021, the Centers for Medicare and Medicaid Services (CMS) requires all hospitals to publish their commercially negotiated prices. To our knowledge, price variation of spine oncology diagnosis and treatments has not been previously investigated. PURPOSE: The aim of this study is to characterize the availability and variation of prices for spinal oncology services among National Cancer Institute-Designated Cancer Centers (NCI-DCC). STUDY DESIGN: Cross-sectional analysis. METHODS: Cancer centers were identified; those that did not provide patient care or participate in Medicare's Inpatient Prospective System were excluded. A cross-sectional analysis was conducted to gather commercially negotiated prices by searching online for "[center name] price transparency OR machine-readable file OR chargemaster." Data obtained was queried using 44 current procedural terminology (CPT) codes for imaging, procedures, and surgeries relevant to spine oncology. Comparison of prices was achieved by normalizing the median price for each service at each center to the estimated 2022 Medicare reimbursement for the center's Medicare Administrator Contractor. The ratios between the lowest and highest median commercial negotiated price within a center and across all centers were defined as "within-center ratio" and "across-center ratio" respectively. RESULTS: In total, 49 centers disclosed commercial payer-negotiated rates. Mean rate (±SD) for cervical corpectomy was $9,134 (±$10,034), thoracic laminectomy for neoplasm excision was $5,382 (±$5502), superficial bone biopsy was $1,853 (±$1,717), and single-photon emission computerized tomography (SPECT) was $813 (±$232). Within-center ratios ranged from 5.0 (SPECT scan) to 17.8 (radiofrequency bone ablation). Across-center ratios (for codes with > 10 centers reporting) ranged from 9.0 (corpectomy, thoracic, lateral extra-cavitary) to 418.7 (anterior approach cervical corpectomy). CONCLUSIONS: Price transparency for spinal oncology remains elusive despite recent CMS regulatory oversight, with marked heterogeneity in the quality of published rates complicating patients' ability to "shop" for care. Additionally, there continues to be significant variation in commercial rates for spine oncology diagnosis and treatment. CLINICAL SIGNIFICANCE: Despite regulation by CMS, prices for spinal oncology services are not uniformly available to patients and vary between NCI-DCC. The findings of this manuscript present potential barriers for patients to compare and obtain affordable care.

BACKGROUND: Despite the theoretical advantages of treating metastatic bone disease with microwave ablation (MWA), there are few reports characterizing microwave absorption and bioheat transfer in bone. This report describes a computational modeling-based approach to simulate directional microwave ablation (dMWA) in spine, supported by ex vivo and pilot in vivo experiments in porcine vertebral bodies. MATERIALS AND METHODS: A 3D computational model of microwave ablation within porcine vertebral bodies was developed. Ex vivo porcine vertebra experiments using a dMWA applicator measured temperatures approximately 10.1 mm radially from the applicator in the direction of MW radiation (T1) and approximately 2.4 mm in the contra-lateral direction (T2). Histologic assessment of ablated ex vivo tissue was conducted and experimental results compared to simulations. Pilot in vivo experiments in porcine vertebral bodies assessed ablation zones histologically and with CT and MRI. RESULTS: Experimental T1 and T2 temperatures were within 3-7% and 11-33% of simulated temperature values. Visible ablation zones, as indicated by grayed tissue, were smaller than those typical in other soft tissues. Posthumous MRI images of in vivo ablations showed hyperintensity. In vivo experiments illustrated the technical feasibility of creating directional microwave ablation zones in porcine vertebral body. CONCLUSION: Computational models and experimental studies illustrate the feasibility of controlled dMWA in bone tissue.

STUDY DESIGN: Retrospective cohort. OBJECTIVE: To evaluate the clinical relevance, usefulness, and financial implications of intraoperative radiograph interpretation by radiologists in spine surgery. SUMMARY OF BACKGROUND DATA: Due to rising health care costs, spine surgery is under scrutiny to maximize value-based care. Formal radiographic analysis remains a potential source of unnecessary health care costs, especially for intraoperative radiographs. MATERIALS AND METHODS: A retrospective cohort analysis was performed on all adult elective spine surgeries at a single institution between July 2020 and July 2021. Demographic and radiographic data were collected, including intraoperative localization and post-instrumentation radiographs. Financial data were obtained through the institution's price estimator. Radiographic characteristics included time from radiographic imaging to completion of radiologist interpretation report, completion of radiologist interpretation report before the conclusion of surgical procedure, clinical relevance, and clinical usefulness. Reports were considered clinically relevant if the spinal level of the procedure was described and clinically useful if completed before the conclusion of the procedure and deemed clinically relevant. RESULTS: Four hundred eighty-one intraoperative localization and post-instrumentation radiographs from 360 patients revealed a median delay of 128 minutes between imaging and completion of the interpretive report. Only 38.9% of reports were completed before the conclusion of surgery. There were 79.4% deemed clinically relevant and only 33.5% were clinically useful. Localization reports were completed more frequently before the conclusion of surgery (67.2% vs. 34.4%) but with lower clinical relevance (90.1% vs. 98.5%) and clinical usefulness (60.3% vs. 33.6%) than post-instrumentation reports. Each patient was charged $32 to $34 for the interpretation fee, cumulating a minimum total cost of $15,392. CONCLUSIONS: Formal radiographic interpretation of intraoperative spine radiographs was of low clinical utility for spine surgeons. Institutions should consider optimizing radiology workflows to improve timeliness and clinical relevance or evaluate the necessity of reflexive consultation to radiology for intraoperative imaging interpretation to ensure that value-based care is maximized during spine surgeries. LEVEL OF EVIDENCE: 3.

PURPOSE: Barycentremetry in adolescent idiopathic scoliosis (AIS) allows the distribution of masses and their loading of the spine to be studied. In particular, the axial torque on the spine has been studied in AIS, but not after surgical correction. Spinal axial torque was studied in AIS before and after surgery. METHODS: All AIS (Lenke 1 and 3) who underwent posterior spinal fusion surgery at our center in 2019 were included retrospectively. AIS underwent frontal and sagittal biplanar radiographs in the free-standing position before surgery, 4 months after surgery, and at the last follow-up. Their spine and external envelope were reconstructed with validated methods. Spinal axial torque at the apex and the upper and lower end vertebra was calculated. Finally, the preoperative and postoperative values were compared to a previously published reference corridor for asymptomatic subjects. RESULTS: Twenty-nine patients were included (54 ± 11° Cobb angle, 15 ± 2 years old at surgery). The surgical procedure decreased the Cobb angle by 36° ± 11° and decreased the spinal axial torque at the upper end vertebra by 2.5 N/m (95% CI = [1.9; 3]; p < 0.001), at the apex by 0.6 N/m (95% CI = [0.4; 1]; p = 0.004), at the lower end vertebra by 2 N/m (95% CI = [1.5; 2.8]; p < 0.001). Compared to 95th percentile of torque, which was previously evaluated in asymptomatic subjects, more than 90% of patients had higher values at the upper and lower end vertebrae before surgery. Postoperatively, 62% of patients still had higher torque at the upper end vertebra than asymptomatic subjects, while only 38% patients showed abnormal values at the lower junction. CONCLUSION: Results of this study confirm that AIS patients show abnormally high spinal axial torque, especially at the end vertebrae, and that this parameter is normalized postoperatively for only a small number of patients.

BACKGROUND: Opioid use prior to spinal surgery is common among patients with workers' compensation (WC) claims. Extended opioid use for pain management in this population is associated with several adverse outcomes including delayed return to work (RTW). OBJECTIVE: This systematic review and meta-analysis aim to assess the evidence on the association of preoperative opioid use with stable RTW and RTW within 1-year after spinal surgery. MATERIAL AND METHODS: The authors searched MEDLINE, Embase, PsycINFO, Emcare, CINAHL Plus, Scopus, and Web of Science from inception to 14 January 2023. The authors included studies that compared any preoperative opioid use with no opioid use, and those that enabled a comparison of different durations of preoperative opioid use. The primary outcome was stable RTW after spinal surgery. Secondary outcomes were RTW within 1-year after surgery and cost of WC claims. A random effect model was assumed to pool the effect estimate. The GRADE approach was applied to evaluate the certainty of evidence. RESULTS: From 2589 records, 10 studies were included, and of these, nine were considered for quantitative synthesis. All studies were observational with eight retrospective cohort and two case-control studies. Five studies each investigated cervical and lumbar disorders. With moderate certainty evidence, the odds of postoperative stable RTW reduced by half (OR: 0.51, 95% CI: 0.43-0.59; 5549 participants) in patients using opioids preoperatively. Similarly, moderate certainty evidence from 2348 participants demonstrated that the odds of RTW within 1-year after surgery were reduced by more than half in patients with preoperative opioid prescriptions (OR: 0.46, 95% CI: 0.36-0.59). CONCLUSIONS: This systematic review and meta-analysis shows that preoperative opioid use is associated with a reduction in odds of postoperative RTW by half in patients with WC-funded spinal surgery.

STUDY DESIGN: Survey study. OBJECTIVE: The objective of this study was to determine the impact of unexpected in-network billing on the patient experience after spinal surgery. SUMMARY OF BACKGROUND DATA: The average American household faces difficulty paying unexpected medical bills. Although legislative efforts have targeted price transparency and rising costs, elective surgical costs continue to rise significantly. Patients are therefore sometimes still responsible for unexpected medical costs, the impact of which is unknown in spine surgery. METHODS: Patients who underwent elective spine surgery patients from January 2021 to January 2022 at a single institution were surveyed regarding their experience with the billing process. Demographic characteristics associated with unexpected billing situations, patient satisfaction, and financial distress, along with utilization and evaluation of the online price estimator, were collected. RESULTS: Of 818 survey participants, 183 (22.4%) received an unexpected in-network bill, and these patients were younger (56.7 vs. 63.4 y, P <0.001). Patients who received an unexpected bill were more likely to feel uninformed about billing (41.2% vs. 21.7%, P <0.001) and to report that billing impacted surgical satisfaction (53.8% vs. 19.1%, P <0.001). However, both groups reported similar satisfaction postoperatively (Likert >3/5: 86.0% vs. 85.5%, P =0.856). Only 35 (4.3%) patients knew of the price estimator's existence. The price estimator was reported to be very easy or easy (N=18, 78.2%) to understand and very accurate (N=6, 35.3%) or somewhat accurate (N=8, 47.1%) in predicting costs. CONCLUSIONS: Despite new regulations, a significant portion of patients received unexpected bills leading to financial distress and affecting their surgical experience. Although most patients were unaware of the price estimator, almost all patients who did know of it found it to be easy to use and accurate in cost prediction. Patients may benefit from targeted education efforts, including information on the price estimator to alleviate unexpected financial burden.

INTRODUCTION: Some patients, particularly those who are socioeconomically deprived, are diagnosed with primary and/or metastatic cancer only after presenting to the emergency department. Our objective was to determine sociodemographic characteristics of patients undergoing surgery for metastatic spine disease at our institution. METHODS: This retrospective case series included patients 18 years and older who presented to the emergency department with metastatic spine disease requiring surgery. Demographics and survival data were collected. Sociodemographic characteristics were estimated using the Social Deprivation Index (SDI) and Area Deprivation Index (ADI) for the state of California. Univariate log-rank tests and Kaplan-Meier curves were used to assess differences in survival for predictors of interest. RESULTS: Between 2015 and 2021, 64 patients underwent surgery for metastatic disease of the spine. The mean age was 61.0 ± 12.5 years, with 60.9% being male (n = 39). In this cohort, 89.1% of patients were non-Hispanic (n = 57), 71.9% were White (n = 46), and 62.5% were insured by Medicare/Medicaid (n = 40). The mean SDI and ADI were 61.5 ± 28.0 and 7.7 ± 2.2, respectively. 28.1% of patients (n = 18) were diagnosed with primary cancer for the first time while 39.1% of patients (n = 25) were diagnosed with metastatic cancer for the first time. During index hospitalization, 37.5% of patients (n = 24) received palliative care consult. The 3-month, 6-month, and all-time mortality rates were 26.7% (n = 17), 39.5% (n = 23), and 50% (n = 32), respectively, with 10.9% of patients (n = 7) dying during their admission. Payor plan was significant at 3 months ( P = 0.02), and palliative consultation was significant at 3 months ( P = 0.007) and 6 months ( P = 0.03). No notable association was observed with SDI and ADI in quantiles or as continuous variables. DISCUSSION: In this study, 28.1% of patients were diagnosed with cancer for the first time. Three-month and 6-month mortality rates for patients undergoing surgery were 26.7% and 39.5%, respectively. Furthermore, mortality was markedly associated with palliative care consultation and insurance status, but not with SDI and ADI. LEVEL OF EVIDENCE: Retrospective case series, Level III evidence.

BACKGROUND CONTEXT: Recently published studies have revealed a correlation between MRI-based vertebral bone quality (VBQ) score and bone mineral density (BMD) measured using dual X-ray absorptiometry (DXA) or quantitative computed tomography (QCT). However, no studies have determined if differences in field strength (1.5 vs 3.0 T) could affect the comparability of the VBQ score among different individuals. PURPOSE: To compare the VBQ score obtained from 1.5 T and 3.0 T MRI (VBQ1.5T vs VBQ3.0T) in patients undergoing spine surgery and assess the predictive performance of VBQ for osteoporosis and osteoporotic vertebral fracture (VCF). DESIGN: A nested caseâcontrol study based on an ongoing prospective cohort study of patients undergoing spine surgery. PATIENT SAMPLE: All older patients (men aged >60 years and postmenopausal women) with available DXA, QCT and MR images within 1 month were included. OUTCOME MEASURES: VBQ score, DXA T-score, and QCT derived vBMD. METHODS: The osteoporotic classifications recommended by the World Health Organization and American College of Radiology were used to categorize the DXA T-score and QCT-derived BMD, respectively. For each patient, the VBQ score was calculated using T1-weighted MR images. Correlation analysis between VBQ and DXA/QCT was performed. Receiver operating characteristic (ROC) curve analysis, including determination of the area under the curve (AUC), was performed to assess the predictive performance of VBQ for osteoporosis. RESULTS: A total of 452 patients (98 men aged >60 years and 354 postmenopausal women) were included in the analysis. Across different BMD categories, the correlation coefficients between the VBQ score and BMD ranged from -0.211 to -0.511, and the VBQ1.5T score and QCT BMD demonstrated the strongest correlation. The VBQ score was a significant classifier of osteoporosis detected by either DXA or QCT, with VBQ1.5T showing the highest discriminative power for QCT-osteoporosis (AUC=0.744, 95% CI=0.685-0.803). In ROC analysis, the VBQ1.5T threshold values ranged from 3.705 to 3.835 with a sensitivity between 48% and 55.6% and a specificity between 70.8% and 74.8%, while the VBQ3.0T threshold values ranged from 2.59 to 2.605 with a sensitivity between 57.6% and 67.1% and a specificity between 67.8% and 69.7%. CONCLUSIONS: VBQ1.5T exhibited better discriminability between patients with and without osteoporosis than VBQ3.0T. Considering the non-negligible difference in osteoporosis diagnosis threshold values between the VBQ1.5T and VBQ3.0T scores, it is essential to clearly distinguish the magnetic field strength when assessing the VBQ score.

STUDY DESIGN: Descriptive. OBJECTIVE: The objective of this study is to analyze trends in racial, ethnic, and gender diversity in orthopedic spine surgery fellowship trainees. SUMMARY OF BACKGROUND DATA: Orthopedic surgery has consistently been labeled as one of the least diverse fields in Medicine. Although some effort has been made to combat this in recent years at the residency level, it is uncertain whether spine fellowships have had any changes in fellow demographics. MATERIALS AND METHODS: Fellowship demographic data were collected through the Accreditation Council for Graduate Medical Education. Data collected included gender (male, female, and not reported) and race (White, Asian, Black, Hispanic, Native Hawaiians, American Indian or Alaskan Native, other, and unknown). Percentage equivalents were calculated for each group from 2007 to 2008 to 2020 to 2021. A χ 2 test for trend (Cochran-Armitage test) was done to determine whether there was a significant change in percentages of each race and gender during the study period. The results were considered statistically significant at P <0.05. RESULTS: White, Non-Hispanic males represent the largest proportion of orthopedic spine fellowship positions each year. From 2007 to 2021, there were no significant changes in the representation of any race or gender of orthopedic spine fellows. Males ranged from 81% to 95%, Whites from 28% to 66%, Asians from 9% to 28%, Blacks from 3% to 16%, and Hispanics from 0% to 10%. Native Hawaiians and American Indians remained at 0% for all years included in the study. Females and all races, excluding Whites, continue to be under-represented in orthopedic spine fellowship. CONCLUSIONS: Orthopedic spine surgery fellowship programs have not made substantial progress in diversifying its population. More attention is needed to increase diversity in residency programs through pipeline programs, increased mentorship and sponsorship, and early exposure to the field. LEVEL OF EVIDENCE: 1.

INTRODUCTION: The relationship between research productivity in training and future productivity as an attending spine surgeon is not well-established in the literature nor has the effect of geographic location of training institutions on future academic success been investigated. The aim of our study was to (1) summarize characteristics of academically productive spine surgeons, (2) assess predictors of long-term academic productivity, and (3) establish the effect of geographic location on long-term academic productivity. METHODS: A query was conducted of the 2021 to 2022 North American Spine Society Spine Fellowship Directory of all orthopaedic and neurosurgical spine fellowship selection committee members for each institution participating in the spine fellowship match. The attending publication rate and h- index were determined. A multivariate linear regression model was developed. P value was set to <0.05. RESULTS: We identified 310 orthopaedic and neurosurgical spine surgeons, representing 76 fellowship programs. Multivariate linear regression analysis identified that the publications during residency ( P < 0.001) and during fellowship ( P < 0.001) were significant predictors of an increased publication rate as an attending surgeon. By contrast, the preresidency publication rate ( P = 0.729) was not significantly predictive of the attending publication rate. Multivariate analysis of h- index found that residency publication rate had a positive correlation ( P = 0.031) compared with preresidency ( P = 0.579) or fellowship ( P = 0.257) rates. Attendings who had attended residency in the Northeast and currently practicing in the Northeast had a higher publication rate ( P < 0.001 and P = 0.004, respectively). DISCUSSION: A higher number of publications in residency and fellowship were markedly predictive of an increased publication rate as an attending spine surgeon. By contrast, preresidency publications may not be indicative of future academic productivity as an attending. Location may also contribute to attending publication rate and favor those who undergo residency training and ultimately practice in the Northeast.

STUDY DESIGN: Retrospective observational study. OBJECTIVE: Biomechanical and geometrical descriptors are used to improve global alignment and proportion (GAP) prediction accuracy to detect proximal junctional failure (PJF). SUMMARY OF BACKGROUND DATA: PJF is probably the most important complication after sagittal imbalance surgery. The GAP score has been introduced as an effective predictor for PJF, but it fails in certain situations. In this study, 112 patient records were gathered (57 PJF; 55 controls) with biomechanical and geometrical descriptors measured to stratify control and failure cases. PATIENTS AND METHODS: Biplanar EOS radiographs were used to build 3-dimensional full-spine models and determine spinopelvic sagittal parameters. The bending moment (BM) was calculated as the upper body mass times, the effective distance to the body center of mass at the adjacent upper instrumented vertebra +1. Other geometrical descriptors such as full balance index (FBI), spino-sacral angle (SSA), C7 plumb line/sacrofemoral distance ratio (C7/SFD ratio), T1-pelvic angle (TPA), and cervical inclination angle (CIA) were also evaluated. The respective abilities of the GAP, FBI, SSA, C7/SFD, TPA, CIA, body weight, body mass index, and BM to discriminate PJF cases were analyzed through receiver operating characteristic curves and corresponding areas under the curve (AUC). RESULTS: GAP (AUC = 0.8816) and FBI (AUC = 0.8933) were able to discriminate PJF cases but the highest discrimination power (AUC = 0.9371) was achieved with BM at upper instrumented vertebra + 1. Parameter cutoff analyses provided quantitative thresholds to characterize the control and failure groups and led to improved PJF discrimination, with GAP and BM being the most important contributors. SSA (AUC = 0.2857), C7/SFD (AUC = 0.3143), TPA (AUC = 0.5714), CIA (AUC = 0.4571), body weight (AUC = 0.6319), and body mass index (AUC = 0.7716) did not adequately predict PJF. CONCLUSION: BM reflects the quantitative biomechanical effect of external loads and can improve GAP accuracy. Sagittal alignments and mechanical integrated scores could be used to better prognosticate the risk of PJF.
