The Associations of Spine Surgeon Training, Office Wait Times, and Social Media Presence with Reviews on Physician Rating Websites.

This study evaluated the associations of demographics and social media (SM) usage on physician review websites for spine surgeons in New Jersey and Pennsylvania. Three physician rating websites were accessed to obtain training history, number of ratings/reviews, and overall rating (0-5). Surgeon web pages and publicly searchable SM accounts on Facebook (FB), Twitter (T), and/or Instagram (IG) were recorded. Of 246 spine surgeons included, 95.9% had a personal/institutional website while 12.2% were present on at least one SM platform. Physician age was inversely correlated with Healthgrades.com (HG), Vitals.com (V), and Google.com (G) ratings (p < 0.0001). Physicians with SM had higher ratings on HG (p = 0.006) and V (p = 0.006). Spine surgeons with SM received more ratings, comments, and higher scores than those without SM. All review sites agree that SM presence correlated with the number of ratings and comments across physician review websites, suggesting SM may influence patient feedback.

Degenerative Cervical Myelopathy: A Concept Review and Clinical Approach.

STUDY DESIGN: Narrative review. OBJECTIVE: To provide an overview of the evaluation and diagnosis of degenerative cervical myelopathy (DCM). SUMMARY OF BACKGROUND DATA: DCM describes several etiologies of degenerative, nontraumatic spinal cord impairment. Early diagnosis and intervention can decrease neurological decline. METHODS: An extensive literature review was conducted. RESULTS: The incidence and prevalence of DCM are increasing worldwide. Asymptomatic spinal cord compression can progress to cervical myelopathy. Static and dynamic factors contribute to spinal cord compression. Patients frequently present with decreased manual dexterity, gait instability, and neck pain. On physical exam, patients frequently present with upper motor neuron signs, a Lhermitte sign, a failed Romberg test, global proprioceptive dysfunction, and decreased pain sensation. Anatomic variation may complicate physical exam interpretation. The modified Japanese Orthopaedic Association Scale and Nurick Classification, based on functional impairment, provide diagnostic utility. Magnetic Resonance Imaging imaging is useful in narrowing the differential diagnosis, evaluating the severity of neurological impairment, and predicting disease progression. CONCLUSIONS: Understanding the pathophysiology of DCM and the diagnostic utility of the signs and symptoms of DCM is critical. The decision for anterior cervical discectomy and fusion (ACDF), laminoplasty, or combined ACDF and posterior cervical fusion is individualized for each patient.

At-Risk Tackling Techniques and Effectiveness in NCAA Division I Collegiate Football.

Background: Head-down tackling has been associated with injuries to the brachial plexus, cervical spine, and head in high school and collegiate American football. Head-down tackling has also been associated with decreased effectiveness in successful tackles compared with head-up tackling. Purpose: To assess tackling techniques used during National Collegiate Athletic Association (NCAA) Division I football games and to evaluate the successful tackling rates according to technique. Study Design: Cross-sectional study. Methods: Three reviewers analyzed 1000 consecutive solo defensive tackling attempts made in the 2021 season (October to December) by 8 universities within the NCAA Southeastern Conference. Slow-motion replays were used to analyze the success of the tackling attempt, the tackling method, and the initial point of contact with respect to the offensive player's waist. The chi-square or Fisher exact test was used to analyze categorical data, and the 2-tailed Student t-test or the Mann-Whitney U test was used to analyze continuous data. Results: Head-up and head-down tackling occurred in 902 (90.2%) and 98 (9.8%) tackle attempts, respectively. Head-up tackles were successful in 76.2% of the attempts compared with 55.1% for head-down tackles (P < .001). Tackles were made at or above the offensive player's waist in 777 (77.7%) attempts and below the waist in 223 (22.3%) attempts. Tackles at or above the waist were successful in 77.6% of the attempts compared with 61.9% of tackles below the waist (P < .001). The inside-shoulder method was used in 592 (59.2%) tackles, the arm method in 317 (31.7%), the head-across-the-bow method in 72 (7.2%), and the helmet-to-helmet method in 19 (1.9%). Inside-shoulder tackles had the highest success rate of 93.2%, compared with 41.6% for arm (P < .001), 59.7% for head-across-the-bow (P < .001), and 73.7% for helmet-to-helmet (P = .001) tackles. Inside-shoulder tackles resulted in head-up tackling in 92.9% compared with 41.7% for head-across-the-bow (P < .001) and 57.9% for helmet-to-helmet (P < .001) tackles. There were no recorded injuries to the tackler. Conclusion: Head-up tackles, tackles made at or above the offensive player's waist, and inside-shoulder tackles had the highest success rates. Head-down tackling and tackling below the waist were associated with poor tackling methods, including head-across-the-bow and helmet-to-helmet tackles, which had lower success rates.

Pelvic Fixation With a Quad-Rod Technique Using S2 Alar Iliac and Medialized Entry Iliac Screws for Long Fusion Constructs.

PURPOSE: Patients with adult spinal deformity (ASD) may have risk factors for nonunion and subsequent instrumentation failure. This study reviews a novel surgical technique for a quad-rod construct to the pelvis using both S2 alar iliac (S2AI) screw fixation and medialized entry iliac screw fixation as described through three separate cases and a review of the literature. METHODS: This technique facilitates alignment of the construct and rod insertion into the tulip heads. The medialized iliac screw technique also avoids the potential soft-tissue complications of the conventional iliac screw bolt given that it is deeper and has more soft-tissue coverage. RESULTS: Three cases performed by the most senior author (V.A.) in which this novel technique was used are presented in this report along with clinical and radiographic images to educate the reader on appropriate execution of this technique. A review of the existing literature regarding pelvic fixation techniques for ASD was also done. CONCLUSION: Quad-rod augmentation of long thoracolumbar spinal constructs with two independent SI anchoring points is potentially an effective technique to increase lumbar sacral construct rigidity, thereby promoting fusion rates and decreasing revision rates. The described technique provides spine surgeons with an additional tool in their armamentarium to treat patients with complex ASD.

Clinical Outcomes of Bariatric Surgery Before Spinal Fusion: A Systematic Review.

INTRODUCTION: Morbidly obese patients are at increased risk for intraoperative and postoperative complications following spinal fusion. Preoperative weight loss can improve clinical outcomes. The present systematic literature review is aimed to evaluate the hypothesis that bariatric surgery before spinal fusion surgery is associated with higher rates of complications and revisions. METHODS: Three databases were queried for literature pertaining to bariatric surgery prior to spinal fusion. A 2-author screening process was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Methodologic index for non-randomized studies criteria was used to objectively assess the methodologic quality of the studies reviewed. Retrospective cohort studies in which the patients underwent bariatric surgery were included. RESULTS: Four retrospective cohort studies consisting of a total of 180,090 patients were included. Length of stay was significantly shorter for the bariatric surgery (BS) group patients than the control (C) groups patients (P = 0.009). There were no significant differences in 1-year mortality rate (P = 1.0), readmission rate (P = 0.86), overall postoperative complications (P = 0.83), and postoperative infections (P = 0.97) between the BS and C groups. CONCLUSIONS: There were no consistent differences in rates of postoperative complications, infections, hospital readmission, and mortality between obese patients with bariatric surgery prior to spinal fusion and control group patients. The present study does not support the hypothesis that bariatric surgery before spinal fusion contributes to a higher rate of postoperative complications in patients undergoing spinal fusion.

Routine Histopathologic Examination of Bone Obtained During Elective Primary Total Knee Arthroplasty May Not Be Necessary.

Background: Many institutions require the routine collection of pathology samples from every primary total knee arthroplasty (TKA) performed. These policies are controversial, and their cost-effectiveness is difficult to define. We sought to judge the cost-effectiveness of one such policy according to World Health Organization recommendations. Methods: We analyzed 3200 consecutive primary TKAs, comparing our presumed preoperative diagnoses against the diagnoses made by the pathologist. Diagnoses were categorized as concordant (matching), discrepant (not matching but without impact to patient management), or discordant (not matching and resulting in a direct change to patient management). An incremental cost-utility ratio analysis was performed to determine the cost-effectiveness of our institution's policy to routinely collect pathology samples from every primary TKA performed. Cost-effectiveness was defined by World Health Organization guidelines as a cost of less than $228,090 per quality-adjusted life year gained. Results: Twelve pathology samples were lost before reaching a pathologist. From the remaining 3188 samples, we identified 3158 concordant cases, 29 discrepant diagnoses, and 1 discordant diagnosis. It cost an estimated $10,522.60 to identify each discrepant diagnosis and an estimated $305,155.36 to diagnose one discordant case in our cohort. Our incremental cost-utility ratio analysis revealed that we spent $305,155.36 to gain 0 quality-adjusted life years for our patients. Conclusions: Routine histopathologic analysis of TKA samples was cost-ineffective in our patient cohort and may not be necessary during routine TKA.

Crossing the cervicothoracic junction: an evaluation of radiographic alignment, functional outcomes, and patient-reported outcomes.

OBJECTIVE: There is currently no consensus regarding the appropriate lower instrumented vertebra (LIV) for multilevel posterior cervical fusion (PCF) constructs between C7 and crossing the cervicothoracic junction (CTJ). The goal of the present study was to compare postoperative sagittal alignment and functional outcomes among adult patients presenting with cervical myelopathy undergoing multilevel PCF terminating at C7 versus spanning the CTJ. METHODS: A single-institution retrospective analysis (January 2017-December 2018) was performed of patients undergoing multilevel PCF for cervical myelopathy that involved the C6-7 vertebrae. Pre- and postoperative cervical spine radiographs were analyzed for cervical lordosis, cervical sagittal vertical axis (cSVA), and first thoracic (T1) vertebral slope (T1S) in two randomized independent trials. Modified Japanese Orthopaedic Association (mJOA) and Patient-Reported Outcomes Measurement Information System (PROMIS) scores were used to compare functional and patient-reported outcomes at the 12-month postoperative follow-up. RESULTS: Sixty-six consecutive patients undergoing PCF and 53 age-matched controls were included in the study. There were 36 patients in the C7 LIV cohort and 30 patients in the LIV spanning the CTJ cohort. Despite significant correction, patients undergoing fusion remained less lordotic than asymptomatic controls, with a C2-7 Cobb angle of 17.7° versus 25.5° (p < 0.001) and a T1S of 25.6° versus 36.3° (p < 0.001). The CTJ cohort had superior alignment corrections in all radiographic parameters at the 12-month postoperative follow-up compared with the C7 cohort: increase in T1S (ΔT1S 14.1° vs 2.0°, p < 0.001), increase in C2-7 lordosis (ΔC2-7 lordosis 11.7° vs 1.5°, p < 0.001), and decrease in cSVA (ΔcSVA 8.9 vs 5.0 mm, p < 0.001). There were no differences in the mJOA motor and sensory scores between cohorts pre- and postoperatively. The C7 cohort reported significantly better PROMIS scores at 6 months (22.0 ± 3.2 vs 11.5 ± 0.5, p = 0.04) and 12 months (27.0 ± 5.2 vs 13.5 ± 0.9, p = 0.01) postoperatively. CONCLUSIONS: Crossing the CTJ may provide a greater cervical sagittal alignment correction in multilevel PCF surgeries. However, the improved alignment may not be associated with improved functional outcomes as measured by the mJOA scale. A new finding is that crossing the CTJ may be associated with worse patient-reported outcomes at 6 and 12 months of postoperative follow-up as measured by the PROMIS, which should be considered in surgical decision-making. Future prospective studies evaluating long-term radiographic, patient-reported, and functional outcomes are warranted.

Vascular Injury After Knee Dislocation: A Meta-Analysis Update.

INTRODUCTION: Multisystem injuries affecting vasculature and nerves can be detrimental sequelae of knee dislocations (KDs). The purpose of this study was to provide an update of the current literature since the conducted search used in the publication of Medina et al on May 3, 2013, to evaluate (1) the frequency of vascular and neurologic injury after KD, (2) the frequency with which surgical intervention was conducted for vascular injury in this setting, and (3) the frequency with which each imaging modality was used to detect vascular injury. METHODS: A two-author screening process was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using the MEDLINE database. Frequency of vascular injury, surgical intervention, and amputation after KD were analyzed. Diagnostic modalities used in the acute-care setting were also evaluated. RESULTS: Nineteen articles were analyzed for a total of 37,087 KDs. Of these, 10.7% sustained vascular injuries and 19.6% sustained nerve injuries. Overall, 62.2% of patients with vascular injury underwent surgical repair and 2.2% limbs resulted in amputation. Angiography was the most frequently used diagnostic modality (91.7%). DISCUSSION: This review updates our understanding on the clinical implications of KDs including frequency of vascular injury (10.7%), amputation (2.2%), and nerve injuries (19.6%). Compared with prior literature, there was an increased prevalence of KD1 (32.4%) and lateral KDs (80.4%). Most vascular injuries after KD undergo surgical repair (62.2%).

Characteristics and Trends of the Most Cited Publications in The Journal of Arthroplasty.

Background: This study aims to identify the most frequently cited articles published in the Journal of Arthroplasty (JOA) and to analyze the trends in the content and contributors of the literature within the journal. Methods: The 100 most cited articles published in the JOA were accessed using the Scopus database. The number of citations, year of publication, level of evidence (LOE), article type, country of origin, and contributing institution were each recorded for each article. Results: The United States (63%) was the most prolific publishing nation. The 1990s (30%) and 2000s (47%) were the most productive decades. The most common article category was clinical outcomes (33%), followed by technical note (16%) and biomechanics (14%). The plurality of the top 100 articles were well-designed case-control or cohort studies of LOE II (46%) followed by LOE V (32%) and LOE I (11%). Conclusions: Using citation analysis, the most influential articles in the JOA were comprehensively and objectively analyzed. The most popular fields of research involved clinical outcomes (33%) and technical note (16%), both of which increase an article's likelihood of being highly cited. Knowledge of the most influential articles in the JOA allows for appreciation of current and potential future areas of literature regarding diagnosis, management, and outcome of a patient undergoing arthroplasty.

Severe Heterotopic Ossification After Revision Total Knee Arthroplasty: A Case Report and Review of the Literature.

The incidence of primary and revision total knee arthroplasty (TKA) is increasing worldwide. Heterotopic ossification is a common and concerning complication of TKA. There are few described cases of severe heterotopic ossification after revision TKA and no known cases of heterotopic ossification causing functional ankylosis after revision TKA. We describe a case of extensive heterotopic ossification in a patient who underwent right TKA for extensive adhesions and stiffness. After early range of motion improvement postoperatively, the patient discontinued a physical therapy regimen. The patient presented 13 years after revision TKA with radiographically evidenced severe heterotopic ossification resulting in a functional ankylosis. The patient elected for nonsurgical management. This case demonstrates a delayed finding of severe heterotopic ossification. The case prompted an applied literature review of several topics: heterotopic ossification as a complication of revision arthroplasty, the contribution of autoimmune and inflammatory conditions to heterotopic ossification; the use of medication, radiation, and physical therapy as prophylaxis against heterotopic ossification; and the range of treatment strategies for severe heterotopic ossification at the knee joint. Consent by the patient involved in this case report was obtained.

Characteristics and Trends of the Most Cited Clinical Orthopaedics and Related Research Articles.

Background: Clinical Orthopaedics and Related Research is one of the most influential and reputable scientific journals in the field of orthopaedics. Some of the most reputable publications related to orthopaedic research can be attributed to this journal and it continues to have a significant impact on modern research. Objective: The purpose of this study is to identify the most influential articles, in terms of number of citations, published by Clinical Orthopaedics and Related Research. The goal of analyzing the most cited articles in is to create a baseline for future researchers to build upon and to uncover any trends in orthopaedic research. Methods: Preferred Reporting Items for Systematic Reviews guidelines were used to structure the data collection and analysis of this study. The Scopus database was used to compile the publication data. Data was then exported to an excel sheet to be further analyzed via a multi-author review process. Results: The most cited article was "A Clinical Method of Functional Assessment of the Shoulder" by Constant et al.. The 50 articles analyzed in this study were cited a total of 32,404 times, averaging 719 citations per year, per publication. The oldest article was published in 1971, and the newest in 2008. The United States was the country with the most attributable publications and The University of Florida was the most contributory institution. Conclusions: Our study recognizes Clinical Orthopaedics and Related research as having a strong predilection for older articles and a continued strength for modern publications.

Demographic and economic trends in vertebral fracture surgeries throughout the United States.

Background: Vertebral fractures, frequently resulting from high-impact trauma to the spine, are an increasingly relevant public health concern. Little is known about the long-term economic and demographic trends affecting patients undergoing surgery for such fractures. This study examines national economic and demographic trends in vertebral fracture surgery in the United States to improve value-based care and health care utilization. Methods: The National Inpatient Sample (NIS) was queried for patients who underwent surgical treatment of a vertebral fracture (ICD-9-CM-3.53) (excluding kyphoplasty and vertebroplasty) between 1993 and 2015. Demographic data included patient age, sex, income, insurance type, hospital size, and location. Economic data including aggregate charge, aggregate cost, hospital cost, and hospital charge were analyzed. Results: The number of vertebral fracture surgeries, excluding kyphoplasty and vertebroplasty, increased 461% from 3,331 in 1993 to 18,675 in 2014, while inpatient mortality increased from 1.9% to 2.5%.The mean age of patients undergoing vertebral fracture surgeries increased from 42 in 1993 to 53 in 2015. The aggregate cost of surgery increased from $189,164,625 in 2001 to $1,060,866,580 in 2014, a 461% increase. Conclusions: The significant increase in vertebral fracture surgeries between 1993 and 2014 may reflect an increased rate of fractures, more surgeons electing to treat fractures surgically, or a combination of both. The increasing rate of vertebral fracture surgery, coupled with increasing hospital costs and mortality, signifies that the treatment of vertebral fractures remains a challenging issue in healthcare. Further research is necessary to determine the underlying cause of both the increase in surgeries and the increasing mortality rate.

Intracranial hemorrhage after spinal surgery: a literature review.

Background and Objective: Intracranial hemorrhage following spinal surgery is an infrequent but severe complication. Due to its rarity, the etiology, clinical characteristics, and treatment have not yet been fully elucidated. This literature review analyzed the incidence, clinical manifestations, hemorrhage location, current therapeutic strategies, location of operation, and interval time between surgery and bleeding. The objectives of the article were to provide insights for clinicians to promptly identify and prevent potential cases of intracranial hemorrhage. Methods: The authors queried PubMed and Web of Science databases using predefined keywords and included published literature reporting on intracranial hemorrhage after spinal surgery. Relevant case reports, case series, and reviews describing the mechanism of intracranial hemorrhage after spinal surgery and meeting diagnostic criteria for intracranial hemorrhage related to spinal surgery were included. Clinico-demographc data, presentations symptoms, location, index surgery type, and neurological outcomes after brain hemorrhage. Oxford Centre Level of Evidence guidelines was used to evaluate the quality of included studies. Descriptive statistics were used to synthesize the results. Key Content and Findings: A total of 80 publications of level of evidence IV involving 108 patients with median age at diagnosis was 58.5 years (inter-quartile range: 6-85) were analyzed. The incidence of intracranial hemorrhage was 0.08-0.37% among patients who underwent spinal surgery, and this complication occurred predominantly within 48 hours postoperatively. The initial presentation included headache, reduced level of consciousness, dysarthria, nausea, vomiting, hearing loss, blurred vision, neck rigidity, and delayed recovery from anesthesia. More than half (58.3%) of patients improved, while 23.1% still experienced neurological dysfunctions, and 7.4% died. Conclusions: The present study is limited by the levels of evidence of the included studies. There is heterogeneity among cases with respect to patient demographics and medical history. Angiography is critical in assessing the presence and extent of underlying vascular diseases. Intracranial hemorrages may be caused by intraoperative or postoperative cerebrospinal fluid leakage that will lead to intracranial pressure change and induced by intracranial venous or arterial bleeding. The treatment strategies include conservative medical management and surgical treatment. Individualized treatment should be emphasized.

The Demographics and Epidemiology of Infantile, Juvenile, and Adolescent Idiopathic Scoliosis in a Southern California Integrated Health Care System.

STUDY DESIGN: Prognostic study, Level III. OBJECTIVES: The aim of this study was to determine the incidence and demographics of idiopathic scoliosis (IS) in a large cohort of children in a Southern California integrated healthcare system, and to identify the demographic or clinical factors associated with the greatest risk of IS. SUMMARY OF BACKGROUND DATA: Although many authors have reported on the incidence and prevalence of IS in children, there have been few incidence studies in the United States on large, self-contained populations. METHODS: A retrospective chart analysis was done on diagnosed cases of IS within our integrated health care system in patients under age 18 years during the entire 2013 calendar year. Patient demographics were recorded and the incidence of IS was determined. Odds ratios (ORs) for having IS and for having more severe initial curve magnitudes based on demographics were determined using logistic regression models. RESULTS: IS Incidence was 3.9, 28.6, and 393 per 100,000, respectively, for the infantile, juvenile, and adolescent group. The female incidence was more than twice that of males in all age groups. Multivariate logistic regression analysis showed Asians and non-Hispanic Whites had the highest OR of IS (OR 1.54 and 1.32 with 95% confidence interval [CI] 1.33-1.79 and 1.19-1.47). Whites, Blacks, and mixed-race patients had a significantly higher initial curve magnitude than Hispanics; females also had a significantly greater initial curve magnitude than boys (18.1° vs. 16.7°). Underweight patients had a 50% increased OR of IS versus normal weight (95% CI 1.16-1.94) with a progressively decreased OR of IS as weight increased. CONCLUSION: Our study of a large integrated healthcare system sheds light on the incidence of IS and the ORs based on weight, sex, and ethnicity/race. The overall incidence was lower overall than previously thought.Level of Evidence: 3.

Return to Golf Following Cervical and Lumbar Spinal Fusion: A Systematic Review.

BACKGROUND: There is a paucity of literature about return to play (RTP) for golf protocols following cervical and lumbar fusions. The timing of return to this sport is a common question among patients. The aim of this review was to analyze and report the current protocols for RTP following cervical and lumbar spinal fusion. METHODS: A systematic search was conducted using the following databases: MEDLINE, PubMed, Web of Science, Scopus, and Google Scholar. A 3-step, multiauthor screening process was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Inclusion criteria included peer-reviewed and published prospective, case-control, cohort, case series, or review articles. Studies had to pertain to RTP for golf following instrumented cervical or lumbar spinal fusion to be included. RESULTS: Three articles met inclusion criteria: 2 retrospective survey-based cohort studies and 1 survey-based case series study. All studies included a minimum of 1 year of follow-up. Of patients, 71.6% (n = 51) were able to RTP following surgery; 54.3%-80% were able to RTP at a similar or improved level of play as preoperatively. Postoperative pain reduction was noted in 2 articles. CONCLUSIONS: Most golfers are able to RTP within 12 months following cervical or lumbar spinal fusion. Patients generally reported decreased lower back pain and leg pain postoperatively. Following cervical or lumbar fusion, many golfers are able to RTP at the same or an increased frequency compared with preoperatively.

Characteristics and Trends of the Most Cited Spine Publications.

STUDY DESIGN: Bibliometric literature review. OBJECTIVE: The aim of this study was to recognize and analyze the most frequently cited manuscripts published in the journal Spine. SUMMARY OF BACKGROUND DATA: Although the journal Spine is considered a premiere location for distributing influential spine research, no previous study has evaluated which of their publications have had the most impact. Knowledge and appreciation of the most influential Spine publications can guide and inspire future research endeavors. METHODS: Using the Scopus database, the 100 most cited articles published in Spine were accessed. The frequency of citations, year of publication, country of origin, level-of-evidence (LOE), article type, and contributing authors/institutions were recorded. The 10 most cited articles (per year) from the past decade were also determined. RESULTS: "Guidelines For The Process Of Cross-Cultural Adaptation Of Self-Report Measures" by Beaton DE was the most cited article with 2960 citations. 2000 to 2009 (n = 46) was the most productive period. A LOE of III (n = 35) followed by II (n = 34) were the most common. Deyo RA (n = 8), Bombardier C (n = 6), and Waddell G (n = 6) produced the most articles. University of Washington (n = 8) and University of Toronto (n = 8) ranked first for institutional output. Clinical Outcome (n = 28) was the most recurring article topic. The United States (n = 51) ranked first for country of origin. CONCLUSION: Using citation analysis as an objective proxy for influence, certain publications can be distinguished from others due to their lasting impact and recognition from peers. Of the top cited Spine publications, many pertained to clinical outcomes (28%) and had a LOE of I, II, or III (60%). Although older publications have had longer time to accrue citations, those in the most recent decade comprise this list almost 2:1. Knowledge of these "classic" publications allows for a better overall understanding of the diagnosis, management, and future direction of spine health care.Level of Evidence: 3.

The 50 Most Cited Articles in the Indications, Risk Factors, Techniques, and Outcomes of ACL Revision Surgery.

The rate of anterior cruciate ligament (ACL) retear remains high and revision ACL reconstruction has worse outcomes compared with primaries. To make advances in this area, a strong understanding of influential research is necessary. One method for systematically evaluating the literature is by citation analysis. This article aims to establish and evaluate "classic" articles. With consideration of these articles, this article also aims to evaluate gaps in the field and determine where future research should be directed. The general approach for data collection and analysis consisted of planning objectives, employing a defined strategy, reviewing search results using a multistep and multiauthor approach with specific screening criteria, and analyzing data. The collective number of citations for all publications within the list was 5,203 with an average of 104 citations per publication. "Biomechanical Measures during Landing and Postural Stability Predict Second Anterior Cruciate Ligament Injury after Anterior Cruciate Ligament Reconstruction and Return to Sport" by Paterno et al contained both the highest number of total citations and the highest number of citations per year, with 403 total citations and 43.9 citations per year. The most recurring level of evidence were level II (n = 18) and level III (n = 17). "Clinical Outcomes" was the most common article type (n = 20) followed by "Risk Factors" (n = 10). The American Journal of Sports Medicine had the highest recorded Cite Factor with over 50% of the articles (n = 27) published. The most productive authors included R.W. Wright (n = 6), S.D. Barber-Westin (n = 5), F.R. Noyes (n = 5), and K.P. Spindler (n = 5). Historically, influential studies have been published in the realms of clinical outcome and risk factor identification. It has been established that revision ACL reconstruction has worse outcomes and more high-level studies are needed. Additionally, prospective studies that apply the knowledge for current known risk factor mitigation are needed to determine if graft tear rates can be lowered.

The 50 Most-Cited Papers on Bankart Lesions.

PURPOSE: To analyze the 50 most-cited articles pertaining to "Bankart lesions," also known as anteroinferior labral tears, by means of citation analysis as well as to provide analysis and summary of the origins and trends of research on Bankart lesions. METHODS: Scopus was used to query the literature on Bankart lesions. Included articles were related to Bankart lesions and the indications, risk factors, techniques, and outcomes of arthroscopic and open Bankart repair. The 50 most-cited articles were analyzed in the following areas: year of publication, citations in the most recent year, total citation count, contributing authors, institutions, countries, and journals, article classifications, and level of evidence. RESULTS: Years of publication ranged from 1938 to 2013. There were 608 total citations in the most recent year. Total citation count was 12,441. Regarding country, journal, and authorship, United States, R. A. Arciero, and Arthroscopy were the highest respective contributors. Rush University had the greatest number of publications. The most common article classification was clinical outcomes. Of 49 clinical articles, the most frequent Level of Evidence was IV. The majority of the top 50 Bankart literature consisted of case series and retrospective studies performed in the United States. CONCLUSIONS: Our findings are consistent with the hypothesis that the 50 most-cited articles about Bankart lesions are predominantly U.S.-based, produced by academic orthopaedic groups, clinical outcomes articles, and of Level IV and V evidence. This list of articles should serve as a reference tool for any orthopaedist looking to review Bankart literature.

Social Media Presence Correlated with Improved Online Review Scores for Spine Surgeons.

BACKGROUND: In the next decade, health care reimbursement will be more aligned to patient clinical outcomes. These outcomes are influenced by the patient's perceived opinion of his or her care. An evaluation into the role of surgeon demographics, social media (SM) accessibility, and office wait times was conducted to identify correlations with these among 3 online review platforms. METHODS: A total of 206 (148 orthopedic, 58 neurosurgery trained) spine surgeons were included. Spine surgeon ratings and demographics data from 3 physician rating websites (Healthgrades.com [HG], Vitals.com, Google.com [G]) were collected in November 2019. Using the first 10 search results from G we then identified if the surgeons had publicly accessible Facebook, Twitter, or Instagram (IG) accounts. RESULTS: The mean age of the cohort was 54.3 years (±9.40 years), and 28.2% had one form of publicly accessible SM. Having any SM was significantly correlated with higher scores on HG and G. An IG account was associated with significantly higher scores on all 3 platforms, and having a Facebook account correlated with significantly higher scores on HG in multivariate analysis. An office wait time between 16 and 30 minutes and >30 minutes was associated with worse scores on all 3 platforms (all P < 0.05). An academic practice was associated with higher scores on all 3 platforms (P < 0.05). CONCLUSIONS: A shorter office wait time and an academic setting practice are associated with higher patient satisfaction scores on all 3 physician review websites. Accessible SM accounts are also associated with higher ratings on physician review websites, particularly IG.

Trends in Leadership at Spine Surgery Fellowships.

STUDY DESIGN: Cross-sectional study. OBJECTIVE: To illustrate demographic trends among spine fellowship leaders (FLs). SUMMARY OF BACKGROUND DATA: No previous study in the orthopedic literature has analyzed the demographic characteristics or past surgical training of FL in an orthopedic sub-specialty. We attempt to illustrate demographic trends among spine fellowship leadership including fellowship directors (FDs) and co-fellowship directors (co-FDs). We also highlight the institutions that have trained these leaders at various levels. METHODS: Our search for FDs was constructed from the 2018 to 2019 North American Spine Surgery (NASS) Fellowship Directory. Datapoints gathered included: age, sex, residency/fellowship training location, time since training completion until FD appointment, length in FD role, and personal research H-index. RESULTS: We identified 103 FLs consisting of 67 FDs, 19 co-FDs, and another 16 individuals with a synonymous leadership title. 96.1% (99) of the leadership consisted of males while 3.9% (4) were female. The mean age was 52.9 years old and the mean h-index of the FLs was 23.8. FLs were trained in orthopedic surgery (n = 89), neurosurgery (n = 13), or combined orthopedic surgery and neurosurgery training (n = 1). The top fellowships programs producing future FLs were: Case Western Reserve University, Cleveland (n = 10), Washington University, St. Louis (n = 9), and Rothman Orthopaedic Institute, Thomas Jefferson University, Philadelphia (n = 7). CONCLUSION: Spine surgery fellowship directors are more likely to have graduated from certain residency and fellowship programs. This finding could be a result of the training provided by these centers or the institution's predilection to select applicants that are more likely to later seek academic leadership roles post-training.
