Publication Conventional Radiotherapy Timing and Wound Complication Avoidance After Surgery for Metastatic Spine Disease. A LatAm Modified Delphi Study(2025) Landriel, Federico; White, Kevin; Padilla Lichtenberger, Fernando; Guiroy, Alfredo; Teles, Alisson; Laos Plasier, Eduardo; Buzetti Milano, Jerônimo; Risso, Marcelo; Astur, Nelson; González, Oscar; Yurac, Ratko; Páez, Rodolfo; Teixeira, William; Toscano, Maximiliano; Hem, SantiagoBackground Combining surgery and radiotherapy is the gold standard in treating spinal metastasis when spinal stabilization or surgical decompression is required. Determining the optimal timing for radiotherapy postsurgery is crucial to balance treatment efficacy minimizing wound complications. The study aimed to identify consensus and nonconsensus areas among Latin American spinal surgeons regarding the use, timing, risks, and surgical approach to conventional external beam radiotherapy (cEBRT) following spinal surgery for metastases, specifically focusing on the risk of radiotherapy-related wound complications. Methods A modified Delphi survey was conducted. The expert panel included active members of AOSpine Latin America with extensive experience in vertebral metastasis surgery. The surveys include 37 statements covering areas of interest. Inter-expert consensus was considered weak (70-79.9%), moderate (80-89.9%), and strong (≥90%). Results At least 70% consensus was reached on 32 of the 37 statements (86.5%). This included strong consensus on 10 statements, moderate on 13, and weaker on nine. There was high consensus on sutures and lower consensus on risk factors for cEBRT delay. Experts reached strong agreement on the importance of poor nutrition as a risk factor for cEBRT-related wound complications. Perception of wound risk was greater with a posterior midline approach compared to other approaches, and the highest perceived complication risks were for junctional locations and sacral spine. Conclusions We report strong agreements among the experts on important issues such as waiting times and risk factors for cEBRT. The findings underscore the significance of considering factors such as, spinal levels, surgical approaches, and sutures when making clinical decisions.Item Twelve Years of Scientific Production on Medline by Latin American Spine Surgeons(Public Library of Science, 2014) Martins, Delio; Guyot, Juan; Silva, Alvaro; Jiménez, José; Defino, Helton; da Silva, Pedro; Teles, Alisson; Botelho, Ricardo; Falavigna, AsdrubalBackground: Despite the small contribution of LA in the Science Citation Index (SCI), a growing contribution by LA research to international literature has been observed in recent years. Study Design Systematic review. Purpose: To evaluate the scientific contribution of Latin American (LA) Spine Surgeons in the last decade. Methods: A literature search of publications by LA 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. The quality of the publication was evaluated with the journal impact factor (IF), Oxford classification and number of citations. Results: This study comprised 320 articles published in the Medline database by LA spine surgeons from 2000 to 2011. In recent years, there has been an increase in the number of publications by LA spine surgeons. It was observed that 38.4% of LA papers were published in LA journals. 46.6% of the articles were published in journals with an IF lower than 1, and there was no statistically significant difference in the number of articles published in journals with a higher IF during the period. Linear-by-linear association analysis demonstrated an improvement in the level of evidence provided by LA articles published in recent years. Conclusions: This study showed a growth in the number of publications in last 12 years by LA spinal surgeons. It is necessary to discuss a way to increase quantity and quality of scientific publications, mainly through a better education in research.
