Surgical timing in traumatic spinal cord injury: current practice and obstacles to early surgery in Latin America.

STUDY DESIGN: Cross-sectional. OBJECTIVES: To evaluate current practice of Latin American spine surgeons regarding surgical timing in patients with traumatic spinal cord injury (tSCI) and to identify potential barriers for early surgery. SETTING: Web-based. METHODS: A web-based questionnaire was sent to members of AOSpine Latin America. Questions involved demographic features, familiarity with management of tSCI, and timing of surgery in various tSCI scenarios. The participants were also asked if they would like to operate earlier on patients with tSCI, indicating potential obstacles to early surgery. RESULTS: A total of 307 surgeons answered the questionnaire. Early surgery (<24 h) is performed by 66.8% for ASIA A, 76.9% for ASIA B, and 76.9% for ASIA C/D injuries. For traumatic cauda equina syndrome (tCES), 85.2% performed surgery within 24 h. For traumatic central cord syndrome (tCCS) without osteoligamentous instability, only 31.5% performed surgery within 24 h and 41.2% follow-up on these patients, indicating surgery if no symptom improvement. Early surgery was performed always or in most cases by 50.4% and 41.8% of surgeons for incomplete and complete tSCI, respectively. The majority (85.4%) would like to operate earlier on patients with tSCI than they actually do. The most frequently perceived barriers to early surgery were difficulty of access to surgical implants (70.9%) and delay in patient transport to reference hospital for surgery (57.8%). CONCLUSION: Latin American spine surgeons tend to operate earlier on patients with tCES and incomplete tSCI, then on those with complete tSCI and tCCS. The most reported obstacles for early surgery involved healthcare resources.

A new nomenclature system for the surgical treatment of cervical spine deformity, developing, and validation of SOF system.

PURPOSE: To develop and assess the reliability of new nomenclature system that systematically organizes osteotomy techniques and briefly describes the surgical approach, the surgical sequence, and the fixation technique for cervical spine deformity (CSD). METHODS: We developed a new classification system (SOF system) for CSD surgery that describes the sequence of surgical approach (S), the grade of osteotomy (O), and the information of fixation (F) using alphanumeric codes. Twenty CSD osteotomies (8 anterior osteotomies, 12 posterior osteotomies) were included in this study to evaluate the inter- and intra-observer agreement based on operation records. Six observers performed independent evaluations of the operation records in random order. Each observer described 20 CSD surgeries using the SOF system twice (> 30 days between assessments) based on operation records to validate SOF system. RESULTS: Overall agreement (among all six observers at the initial assessment) on the anterior and posterior osteotomy was ICC = 0.96 and ICC = 0.91, respectively. Overall agreement (repeat observations after at least 30 days) on the anterior and posterior osteotomy was ICC = 0.96 and ICC = 0.91, respectively. This data showed that both inter- and intra-observer agreement revealed 'excellent'. CONCLUSION: This study introduces the SOF system of the CSD surgery to understand the surgical sequence, the type of osteotomy and the fixation techniques. The investigation of the inter- and intra-observer agreement revealed 'excellent agreement' for both anterior and posterior osteotomies. Thus, SOF system can provide a consistent description of the various CSD surgeries and its use will provide a common frame for CSD surgery and help communicate between surgeons.

Reliability-Based Design Optimization of a Cemented Prosthesis in a Femur Undergoing Bone Remodeling.

This study proposes a numerical methodology to minimize the bone mass loss in a femur with a total hip arthroplasty procedure, considering uncertainties in the material parameters and using a reliability-based design optimization (RBDO) procedure. A genetic algorithm (GA) is applied for optimization, and a three-dimensional finite element (FE) model associated with the bone remodeling procedure is proposed and described to account for the internal and external femoral bone behavior. An example of a femoral prosthesis design is presented as a basis for discussion of the proposed methodologies, and the corresponding reliability level is evaluated. Constraints on the strength of all materials and target reliability levels are inputs to the optimization model. The main prosthesis dimensions and Young modulus are the design variables. The proposed methodology is compared with a well-known deterministic optimization (DO) procedure and the results show that it is important to consider the uncertainties in this kind of problem since in this case, the a posteriori reliability may be low.

Spinal surgery complications: an unsolved problem-Is the World Health Organization Safety Surgical Checklist an useful tool to reduce them?

PURPOSE: To investigate whether the World Health Organization Safety Surgical Checklist (SSC) is an effective tool to reduce complications in spinal surgery. METHODS: We retrospectively evaluated the clinical and radiological charts prospectively collected from patients who underwent a spinal surgery procedure from January 2010 to December 2012. The aim of this study was to compare the incidence of complications between two periods, from January to December 2010 (without checklist) and from January 2011 and December 2012 (with checklist), in order to assess the checklist's effectiveness. RESULTS: The sample size was 917 patients with an average of 30-month follow-up. The mean age was 52.88 years. The majority of procedures were performed for oncological diseases (54.4%) and degenerative diseases (39.8%). In total, 159 complications were detected (17.3%). The overall incidence of complications for trauma, infectious pathology, oncology, and degenerative disease was 22.2%, 19.2%, 18.4%, and 15.3%, respectively. No correlation was observed between the type of pathology and the complication incidence. We observed a reduction in the overall incidence of complications following the introduction of the SSC: In 2010 without checklist, the incidence of complications was 24.2%, while in 2011 and 2012, following the checklist introduction, the incidence of complications was 16.7% and 11.7%, respectively (mean 14.2%). CONCLUSIONS: The SSC seems to be an effective tool to reduce complications in spinal surgery. We propose to extend the use of checklist system also to the preoperative and postoperative phases in order to further reduce the incidence of complications.

Remote Patient Monitoring: A Systematic Review.

Introduction: Remote patient monitoring or telemonitoring aims at improving patient care through digitally transmitted health-related data. That allows early detection of disease decompensation and intervention, patient education and improves patient-physician relationship. Despite its relevance, there are no comprehensive reviews evaluating the variables discussed by clinical studies on telemonitoring. Methods: A systematic literature search of PubMed was performed to identify studies about telemonitoring published between 2000 and 2018. These had to be case reports with >5 cases, comparative or clinical studies/trials. The following variables were evaluated: year of publication, author's country, discussed topic, objective of study, follow-up time, number of telemonitoring patients, primary outcome, use of teleconsultation and tele-education, presence of a control group, effectiveness of telemonitoring, telemonitoring strategies, and level of evidence. Results: After screening 947 records, 272 articles were included. The review showed a growing number of publications over the years, with 43.0% being published between 2015 and 2018, providing generally positive results (76.8%). The United States was responsible for 38.2% of articles. Cardiovascular disease was the topic of 47.8% of studies, whereas surgical pathologies and postoperative care represented only 2.6%. Wireless devices or smartphone apps were the most popular strategy (75.7%), with 17.6% of studies employing tele-education and 24.6% employing teleconsultation measures. Most publications were OCEBM Level of Evidence 2 (73.5%). Conclusion: Telemonitoring appears to maximize patient care and effectiveness of treatment. The number of publications illustrates the growing interest in the matter. Telemonitoring has yet to be evaluated in the setting of postoperative care and surgical pathologies.

Analysis of scientific output by spine surgeons from Japan: January 2000 to December 2013.

BACKGROUND: Over the last decade, the growing body of work on spine pathology has led to developments and refinements in the areas of basic science, diagnosis and treatment of a variety of spine conditions. Scientific publications have a global impact on the international scientific community as they share vital information that can be applied by physicians worldwide to solve their everyday medical problems. The historical background of scientific publication in journals in Japan on the subject of spine is unclear. METHODS: We performed a literature search for publications by Japanese spine surgeons regarding spine or spinal cord topics using an online database: Pubmed.gov (http://www.ncbi.nlm.nih.gov/pubmed/). The results were stored and analyzed at the Laboratory of Clinical Studies and Basic Models of Spinal Disorders of the University of Caxias do Sul. Results were limited to articles published from January 2000 to December 2013. The search terms used were "Japan" AND ("spine" OR "spinal diseases" OR "spinal cord" OR "spinal cord diseases" OR "vertebroplasty" OR "arthrodesis" OR "discectomy" OR "foraminotomy" OR "laminectomy" OR "denervation" OR "back injuries"). Japanese spine surgeons were defined as spine surgeons from orthopedic or neurosurgical specialties where the publication was affiliated with Japanese services. RESULTS: A total of 16,140 articles were identified by the Medline search. Most of the articles were excluded based on information provided in the title and abstract as they were not related to spine surgery. This study comprised 1768 articles published in the Medline database by Japanese spine surgeons from 2000 to 2013. The number of publications rose in a linear fashion, with the number of papers published increasing by 5.4 per year (p = 0.038). In recent years the publications were increasingly performed in conjunction with the neurosurgery and orthopedics specialties. CONCLUSIONS: This study showed a clear increase in publications (on Medline) by Japanese spine surgeons over the last 14 years. While this is a positive development, there is also cause for concern as there is some evidence that the number of young scientists is declining in Japan. Special attention to educating researchers and improving resources for research is crucial to further increase the number and quality of Japanese publications.

Responsiveness of depression and its influence on surgical outcomes of lumbar degenerative diseases.

OBJECTIVE: To demonstrate the responsiveness of depression after surgery for lumbar degenerative disease and to verify the impact of this condition on surgical outcomes. PATIENT SAMPLE: A prospective cohort study with 91 patients with lumbar degenerative diseases who were evaluated preoperatively, at 30 days and 1 year postoperatively. OUTCOME MEASURES: Evolution of depression between the follow-ups and its correlation with satisfaction. METHODS: Depression was assessed with Beck Depression Inventory. According to depression responsiveness, patients were classified into four groups: NN = no depression; ND = normal during the preoperative period and depression within 1 year; DN = depression during the preoperative period and normal within 1 year; DD = depression during the preoperative period and within 1 year. RESULTS: Prevalence of preoperative depression was 28.6% and 17.6% within 1 year postoperatively. Most patients (65.4%) with depression in the preoperative period recovered postoperatively. Poor preoperative HRQoL measures were associated with higher rates of responsiveness of depression during the follow-up. Patients with depression at the 1-year postoperative follow-up had a worse functional outcome. Patients who improved from depression had similar outcome to those without depression. Dissatisfaction within 1 year postoperatively was greater in patients who become depressed after surgery and remain depressed at 1-year follow-up (NN = 8.8%; ND = 42.9%; DN = 17.6%; DD = 44.4%; P = 0.012). CONCLUSION: Most patients with depression in the preoperative recover within 1 year postoperatively. Responsiveness of depression is associated with surgical outcomes. The presence of depression after the surgical treatment, independent of when it starts, had a major negative impact on prognosis.

Strategy to increase research in Latin America: project on education in research by AOSpine Latin America.

BACKGROUND: The emancipatory nature of education requires research as its fundamental base, because physicians can only improve their skills and knowledge through enquiry. The number and quality of scientific publications by Latin-American spine surgeons found in the Medline database was low between 2000 and 2011. Nevertheless, the research Bank Survey of AOSpine Latin America (AOSLA) members showed that 96% of responders were very interested and motivated to perform scientific research. METHODS AND POPULATION: The research officer of AOSLA together with the Country Council and the AOSpine Research Commission established a competency-based curriculum to improve understanding of what is necessary to produce research and the best methods to achieve this goal. The research curriculum was divided into four main components: (1) research educational plan, (2) performing research, (3) technical and professional support and (4) assessment. RESULTS: The competences, learning outcomes and a syllabus on knowledge in research were developed to enable the participants to understand and perform investigations effectively. The eLearning module was designed to improve the competences to access, evaluate and use scientific information available in the main databases efficiently. Research courses were given as an isolated activity four times in Brazil and Mexico and as precourse activities six times in Brazil, Mexico and Peru. The result was an increased number of articles published and works presented at congresses. CONCLUSIONS: The project of education in research can be effectively disseminated and applied across regions, across students and across specialties.

Assessing the evolution of publications by Brazilian spine surgeons in the last decade.

PURPOSE: To evaluate the scientific contribution of Brazilian Spine Surgeons not only in number of publications but also in their quality between January 2000 to December 2011. METHODS: A literature search of publications by Brazilian spinal surgeons on topics concerning the spine or spinal cord was performed using an online database; Pubmed.gov. The results were limited to articles published from January 2000 to December 2011. A total of 1,778 articles were identified after a Medline search. After exclusion criteria, the study comprised 206 articles. The quality of the Journals was assessed with IF and the article quality using the Oxford classification. RESULTS: An increasing number of publications by Brazilian spine surgeons was observed in recent years: 45.1 % of those papers were published during the last 4 years (2008-2011). Clinical studies and case reports were the most frequent types of article published (37.5 vs 31.1 %). An increasing number of Brazilian publications in non-Brazilian journals has been observed in recent years (linear-by-linear association: 5.449, P = 0.020). The Arquivos de Neuro-Psiquiatria was the most frequent journal in which the papers were published (N = 67, 32 %). The IF of the publications varied from 0.021 to 8.017. The analysis of quality of the articles using the Oxford classification demonstrated that most of them provided LOE 4 (N = 113, 54.9 %) or 5 (N = 45, 21.8 %). CONCLUSIONS: There have been an increasing number of publications by Brazilian spine surgeons in recent years and the quality of the articles published has improved. Also the number of publications by Brazilians in non-Brazilian journals has increased in recent years.

Is Shoulder Imbalance a Useful Parameter in the Screening of Idiopathic Scoliosis? A Preliminary Study.

Objective The present study aims to analyze the use of shoulder imbalance as a parameter for scoliosis screening as well as its relationship with other parameters of physical examination. Methods This study assesses a smartphone application that analyzes several parameters of the physical examination in adolescent idiopathic scoliosis. Medical and non-medical examiners applied the screening tool in students in a public school and in a private sports club. After data collection, interobserver correlation was done to verify shoulder imbalance and to compare shoulder imbalance with Adam's bending test and with trunk rotation. Results Eighty-nine participants were examined, 18 of whom were women and 71 of whom were men. Two subjects were excluded from the analysis. The mean age of subjects from the public school was 11.30 years and, for those from the sports club, it was 11.92 years. The examiners had poor-to-slight interobserver concordance on shoulder asymmetry in the anterior and posterior view. No significant statistical correlation was found between shoulder asymmetry and positive Adam's forward bending test. Conclusion Our preliminary study shows that the shoulder asymmetry has a poor correlation with the Adam's forward bending test and measuring trunk rotation using a scoliometer. Therefore, the use of shoulder imbalance might not be useful for idiopathic scoliosis screening. Level of Evidence III; Diagnostic Study.

International and Multicenter Prospective Controlled Study of Dysphagia After Anterior Cervical Spine Surgery.

BACKGROUND: In the context of anterior approach to the cervical spine, dysphagia is a common complication and still without a clear distinction of risk factors. OBJECTIVE: To analyze the risk factors of dysphagia after cervical spine surgery. METHODS: Multicenter prospective study evaluated patients who underwent anterior cervical spine surgery for degenerative pathologies, studying surgical, anesthesia, base disease, and radiological variables (preoperatively, 24 hours, 1 and 3 weeks, and 6 months after surgery), with control group matched. Postoperative dysphagia was assessed by Swallowing Satisfaction Index and Swallowing Questionnaire; besides, based on multiple logistic regression model, a risk factor analysis correlation was applied. RESULTS: In total, 233 cervical patients were evaluated; most common level approached was C5-C6 (71.8%). All showed same decreasing trade for dysphagia incidence-with more cases on cervical group ( P < .05); severe cases were rare. At postoperative day 1, identified risk factors were approach to C3-C4 (4.11, P < .01), loss of preoperative cervical lordosis (2.26, P < .01), intubation attempts ≥2 (3.10, P < .01), and left side approach (1.85, P = .02); at day 7, body mass index ≥30 (2.29, P = .02), C3-C4 (3.42, P < .01), and length of surgery ≥90 minutes (2.97, P = .005); and at day 21, C3-C4 were kept as a risk factor (3.62, P < .01). CONCLUSION: A high incidence level of dysphagia was identified, having a clear decreasing trending (number of cases and severity) through postoperative time points; considering possible risk factors, strongest correlation was the approach at the C3-C4 level-statistically significant at the 24 hours, 7 days, and 21 days assessment.

Comparison Between Surgical and Conservative Treatment for AOSpine Type A3 and A4 Thoracolumbar Fractures without Neurological Deficit: Prospective Observational Cohort Study.

Objective To compare the clinical results between conservative (CS) and surgical treatment (CXS) of A3 and A4 fractures without neurological deficit. Methods Prospective observational study of patients with thoracolumbar fractures type A3 and A4. These patients were separated between the surgical and conservative groups, and evaluated sequentially through the numeric rating scale (NRS), Roland-Morris disability questionnaire (RMDQ), EuroQol-5D (EQ-5D) quality of life questionnaire, and Denis work scale (DWS) up to 2.5 years of follow-up. Results Both groups showed significant improvement, with no statistical difference in pain questionnaires (NRS: CXS 2.4 ± 2.6; CS 3.5 ± 2.6; p > 0.05), functionality (RMDQ: CS 7 ± 6.4; CXS 5.5 ± 5.2; p > 0.05), quality of life (EQ-5D), and return to work (DWS). Conclusion Both treatments are viable options with equivalent clinical results. There is a tendency toward better results in the surgical treatment of A4 fractures.

Prevention of Surgical Site Infections in Spine Surgery: An International Survey of Clinical Practices Among Expert Spine Surgeons.

STUDY DESIGN: Questionnaire-based survey. OBJECTIVES: Surgical site infection (SSI) is a common complication in spine surgery but universal guidelines for SSI prevention are lacking. The objectives of this study are to depict a global status quo on implemented prevention strategies in spine surgery, common themes of practice and determine key areas for future research. METHODS: An 80-item survey was distributed among spine surgeons worldwide via email. The questionnaire was designed and approved by an International Consensus Group on spine SSI. Consensus was defined as more than 60% of participants agreeing to a specific prevention strategy. RESULTS: Four hundred seventy-two surgeons participated in the survey. Screening for Staphylococcus aureus (SA) is not common, whereas preoperative decolonization is performed in almost half of all hospitals. Body mass index (BMI) was not important for surgery planning. In contrast, elevated HbA1c level and hypoalbuminemia were often considered as reasons to postpone surgery. Cefazoline is the common drug for antimicrobial prophylaxis. Alcohol-based chlorhexidine is mainly used for skin disinfection. Double-gloving, wound irrigation, and tissue-conserving surgical techniques are routine in the operating room (OR). Local antibiotic administration is not common. Wound closure techniques and postoperative wound dressing routines vary greatly between the participating institutions. CONCLUSIONS: With this study we provide an international overview on the heterogeneity of SSI prevention strategies in spine surgery. We demonstrated a large heterogeneity for pre-, peri- and postoperative measures to prevent SSI. Our data illustrated the need for developing universal guidelines and for testing areas of controversy in prospective clinical trials.

Genotoxic parameters of human degenerated intervertebral discs are linked to the pathogenesis of disc degeneration.

BACKGROUND: Degenerative disc disease (DDD) is a prevalent disorder that brings great incapacity and morbidity to the world's population. Its pathophysiology is not fully understood. DNA damage can influence this process, but so far, there have been few studies to evaluate this topic and its true importance in DDD, as well as whether there is a relation between degeneration grade and DNA damage. The objective of this study is to evaluate the degree of damage to the DNA and the relation to the severity of DDD and measure its response to this insult compared to live/dead cell parameters and reactive oxygen species activity in human discs. METHODS: An experimental study was performed with 15 patients with grade IV or V Pfirrmann classification who underwent spinal surgery. Five patients were operated on two levels, resulting in 20 samples that were submitted to the comet assay to measure DNA damage. Of these, six samples were submitted to flow cytometry, and apoptosis, necrosis, cell membrane integrity, intracellular esterase activity, reactive oxygen species (ROS), caspase 3 and mitochondrial membrane potential were evaluated. RESULTS: All samples had DNA damage, and the average of index damage (ID) was 78.1 (SD ± 65.11) and frequency damage (FD) was 49.3% (SD ± 26,05%). There was no statistical difference between the Pfirrmann grades and genotoxic damage. Likewise, all samples that underwent flow cytometry showed apoptosis and ROS to many different degrees. CONCLUSIONS: DNA damage occurs in high-grade degeneration of human discs and contributes to activation of the apoptosis pathway and ROS production that can accelerate disc degeneration.

Why are frailty indices not used systematically during preoperative spine consultations?

INTRODUCTION: Frailty indices are highly predictive of major medical and mechanical complications, lengths of hospital stay, and mortality rates after spine procedures. However, several barriers limit the extent to which spine surgeons employ these indices. The main purposes of the current study were to assess the use of frailty indices by Latin-American spine surgeons and identify the main barriers perceived to restrict their clinical application. METHODS: For this cross-sectional survey, a questionnaire evaluating the demographic characteristics of participating surgeons and their utilization of frailty indices were created in Google form and sent by e-mail to every registered member of AO Spine Latin America between October and November 2020. RESULTS: Of the 1047 surgeons sent the survey, 293 responded (response rate=28%). Half of the surgeons (51.7%) said they were unfamiliar with the terms ¨frailty´ and ¨frailty index", while 70.3% claimed not to use any frailty scale during their pre-operative assessments. The most frequently utilized index was the modified Frailty Index (mFI) (18%). The most important perceived barrier was the excessive amount of time required to calculate each patient's frailty score. Ninety-two percent of the spine surgeons felt sure that these scores could influence their therapeutic decisions, while 91% desired an easier-to-use risk-prevention scale. CONCLUSION: The main perceived barriers restricting the use of frailty indices were the time required to complete them, lack of index validation, and need for specific instruments to calculate the index score.

Knowledge, attitudes, and behaviors regarding the use of clinical practice guidelines among spine surgeons in Latin America.

Background: Clinical Practice Guidelines (CPGs) are invaluable tools to assure evidence-based spine surgery care. In this study, we aimed to identify perceptions, barriers, and potential determinants for the use of CPG among Latin American spine surgeons. Methods: A 28-item questionnaire regarding the use of CPGs was sent to the members of AO Spine Latin America. The questionnaire was subdivided into three sections: (1) demographic data; (2) perceptions and awareness of CPGs; (3) and potential barriers to CPG use. Multivariate logistic regression was performed to assess potential associations with CPG use. Results: A total of 304 spine surgeons answered the questionnaire. Most of the participants were male (91.8%) and orthopedic spine surgeons (52.3%) who averaged 45-65 years of age. Most respondents were aware of some CPGs for spine care (68.8%) and reported using them (70.4%); lack of awareness about CPGs was the most frequent barrier to their use (65.1%). Conclusion: Awareness of CPGs in spine surgery is of paramount importance for their use. Educational programs explaining the importance and benefits of spine care CPG surgical and clinical practice would increase the adherence of physicians to the guidelines.

Patients' preferences regarding physicians' gender: a clinical center cross-sectional study.

BACKGROUND: Even with the significant growth of female representation within medicine, inequality and prejudice against this group persist. OBJECTIVE: To analyze patients' preferences regarding the gender of physicians in general and according to different specialties, and the possible reasons behind their choice. DESIGN AND SETTING: Cross-sectional study at the Clinical Center of the University of Caxias do Sul, Brazil. METHODS: Over a three-month period in 2020, 1,016 patients were asked to complete a paper-based 11-item questionnaire. RESULTS: The majority (81.7%; n = 830) of the patients did not have a preference regarding the gender of physicians in general. The preference rate for same-gender physicians was 14.0% (n = 142/1,016), and this preference was more common among female than among male patients (17.6% versus 7.0%; odds ratio, OR = 2.85; 95% confidence interval, CI = 1.80-4.52; P < 0.001). When asked about their preference for the gender of the specialist who they were waiting to see, the overall preference rate for a same-gender professional was 17.2% (n = 175). Preference for same-gender specialists was higher for specialties essentially based on pelvic or breast examination (i.e. gynecology, urology, proctology and mastology), compared with others (33.4% versus 9.7%; OR = 4.69; 95% CI = 3.33-6.61; P < 0.001). CONCLUSIONS: The patients' model for choice of their physician does not seem to involve physicians' gender in general or in the majority of medical specialties. The data presented in this study may make it easier to understand patients' preferences and concerns.

Scientometric Analysis of Publications from 2004-2021 in the Spine Surgery Field: A Latin American Perspective.

OBJECTIVE: To determine characteristics of Latin American (LA) productivity in spine surgery published worldwide between 2004 and 2021 compared between periods and global literature. METHODS: A comprehensive search about LA productivity in the field of spine surgery using the Scopus and PubMed databases was performed in February 2022. The results were limited to articles published in indexed journals from 2004 to 2021. RESULTS: A total of 1447 publications were identified in the study period. The number of publications has increased across evaluated decades, with 583 between 2004 and 2013 (58.3/year) and 864 between 2014 and 2021 (108/year), and a yearly increase was demonstrated (P = 0.0001). Comparing the most productive year in the first (2012) and last decade (2020), a 1.79-fold increase was demonstrated. Brazil ranked first in productivity (51.14%), followed by Mexico (26.40%) and Argentina (8.64%). Coluna/Columna published the largest number, with 309 articles (21.35%). The top 10 institutions published at least 475 (32.82%) and the most productive was the University of Campinas (Brazil, 74). CONCLUSIONS: This scientometric study is one of the first regional evaluations worldwide. The number of publications in the spine surgery field in Latin America has continued to increase over evaluated decades from 58.3 per year to 108, and a 1.79-fold increase between the most productive years for each decade. Brazil is still the greatest contributor (51.14%), with Mexico (26.40%) and Argentina (8.64%) as growing contributor countries. Most publications were classified as Level of Evidence 4, and this result reflects the importance of continuous research development in the quality of research for our region.
