Cross-sectional, international survey.The current study addressed the multi-dimensional impact of COVID-19 upon healthcare professionals, particularly spine surgeons, worldwide. Secondly, it aimed to identify geographical variations and similarities.A survey was distributed surgeons Questions were categorized into domains: demographics, observations, preparedness, personal impact, patient care, future perceptions.902 representing 7 global regions completed survey. 36.8% reported...
Background: Although multiple studies have investigated risk factors for symptomatic adjacent segment disease (ASD) after lumbar fusion, their findings were diverse and inconsistent. This review aimed to summarize ASD in order guide the management of future research. Methods: Six electronic databases systematically searched from inception December 2019. Two reviewers independently screened titles, abstracts, full-text articles identify investigating fusion humans. The methodological quality...
Early onset adjacent segment degeneration (ASD) can be found within six months after anterior cervical discectomy and fusion (ACDF). Deficits in deep paraspinal neck muscles may related to early ASD. This study aimed determine whether the morphometry of preoperative (multifidus semispinalis cervicis) predicted ASD patients with ACDF. Thirty-two cases a two-level ACDF 30 matched non-ASD were identified from large-scale cohort. The total cross-sectional area (CSA) bilateral lean muscle CSAs C3...
The COVID-19 pandemic forced many surgeons to adopt "virtual medicine" practices, defined as telehealth services for patient care and online platforms continuing medical education. purpose of this study was assess spine surgeon reliance on virtual medicine during the discuss future in surgery.A comprehensive survey addressing demographic data practices distributed worldwide between March 27, 2020, April 4, 2020.902 representing seven global regions responded. 35.6% were identified "high...
Background: Concussion in collegiate athletics is one of the most prevalent sport-related injuries United States, with recent studies suggesting persistent deficits neuromuscular control after a concussion and an associated increase risk lower extremity injury. Purpose: To expand on relationship between injury by examining effect multiple concussions (MC) rate odds future athletes return to play (RTP) compared matched controls. Study Design: Cohort study; Level evidence, 3. Methods: From...
Abstract Background The COVID‐19 pandemic has impacted spine care around the globe. Much uncertainty remains regarding immediate and long‐term future of education in this era. Study design Cross‐sectional, international study surgeons. Methods A multi‐dimensional survey was distributed to surgeons world. total 73 questions were asked demographics, observations, personal impact, effect on education, adoption telemedicine, anticipated challenges moving forward. Multivariate analysis performed...
Study Design: Cross-sectional, international survey. Objectives: This study addressed the global perspectives concerning perioperative use of pharmacologic thromboprophylaxis during spine surgery along with its risks and benefits. Methods: A questionnaire was designed implemented by expert members in AO Spine community. The survey distributed to Spine’s surgeon (N = 3805). Data included demographic information, type region practice, anticoagulation principles, different patient scenarios,...
Introduction: Rotator cuff tears are one of the most common injuries worldwide, yet it is difficult to predict which patients will have poor outcomes after arthroscopic rotator repair (RCR). The purpose this study was identify an association between preoperative vitamin D (25D) levels and postoperative complications in RCR. Methods: From a national claims database, undergoing RCR with 25D were reviewed. Patients stratified into 25D-sufficient (≥20 ng/dL) or 25D-deficient (<20 categories...
Abstract Degenerative spine imaging findings have been extensively studied in the lumbar region and are associated with pain adverse clinical outcomes after surgery. However, few studies investigated significance of these “phenotypes” cervical spine. Patients degenerative pathology undergoing anterior discectomy fusion (ACDF) from 2008 to 2015 were retrospectively prospectively assessed using preoperative MRI for disc degeneration, narrowing, displacement, high‐intensity zones, endplate...
A retrospective study with prospectively-collected data.To determine how type, location, and size of endplate lesions on magnetic resonance imaging (MRI) may be associated symptoms clinical outcomes after anterior cervical discectomy fusion (ACDF).Structural abnormalities are important, yet understudied, phenomena in the spine. ACDF is a common surgical treatment for degenerative disc disease; however, adjacent segment degeneration/disease (ASD) develop.Assessed imaging, 861 patients who...
Objective To assess the impact of Modic changes (MC) on preoperative symptoms, and postoperative outcomes in anterior cervical discectomy fusion (ACDF) patients. Methods We performed a retrospective study prospectively collected data ACDF patients at single institution. Preoperative magnetic resonance imagings were used to presence MC. MC stratified by type location, compared without Associations with patient-reported measures, surgical assessed. Results A total 861 included, 356 (41.3%)....
Spine surgeons around the world have been universally impacted by COVID-19. The current study addressed whether prior experience with disease epidemics among spine surgeon community had an impact on preparedness and response toward COVID-19.A 73-item survey was distributed to worldwide via AO Spine. Questions focused on: demographics, COVID-19 preparedness, response, impact. Respondents without epidemic (e.g., SARS, H1NI, MERS) were assessed univariate multivariate modeling. Results of...
Adjacent segment disease (ASDz) is a potential complication following lumbar spinal fusion. A common nomenclature based on etiology and ASDz type does not exist needed to assist with clinical prognostication, decision making, management.The objective of this study was develop an etiology-based classification system for fusion.We conducted retrospective chart review 65 consecutive patients who had undergone both fusion performed by single surgeon subsequent procedure ASDz. We established the...
Study Design. The study is designed as a retrospective cohort study. Objective. aim of this was to identify modifiable and nonmodifiable risk factors postoperative urinary retention in spine surgery patients. Summary Background Data. Postoperative common complication patients undergoing operative procedures requiring anesthesia. Current studies have shown significant for retention, but most are subsequently limited usefulness preventing complication. Several new possible factors, current...
Study Design. Prospective, case series. Objective. To identify and characterize any differences in specific patient factors, MRI findings, features of spontaneous disc resorption, outcomes between patients with single-level multilevel LDH. Background. Lumbar herniation (LDH) is one the most common spinal pathologies worldwide. Though many cases LDH resolve by mechanism underlying this “self-healing” phenomenon remains poorly understood, particularly context herniations. Methods. A one-year...
Retrospective cohort study.To compare clinical outcomes after anterior cervical discectomy and fusion (ACDF) based on preoperative duration of radiculopathy symptoms.There is no clear indication when ACDF become less effective in the setting acute versus chronic symptoms from nerve root compression.A retrospective study consecutive patients who underwent an between 2008 2015 for was performed. Patients were divided into 3 groups: radicular lasting <6 months, 6-12 those with ≥12 months. Neck...
This study describes a novel, combined Modic changes (MC) and structural endplate abnormality phenotype of the cervical spine, which we have termed Modic-Endplate-Complex (MEC), its association with preoperative symptoms outcomes in anterior discectomy fusion (ACDF) patients. was retrospective prospectively collected data at single institution. Preoperative magnetic resonance imagings were used to assess presence MC abnormalities. Patients divided into four groups: MC-only, abnormality-only,...
