Publication CT Scan in Subaxial Cervical Facet Injury: Is It Enough for Decision-Making?(2023) Cabrera, Juan P.; Yurac, Ratko; Joaquim, Andrei F.; Guiroy, Alfredo; Carazzo, Charles A.; Zamorano, Juan José; Valacco, Marcelo; AO Spine Latin America Trauma Study GroupStudy Design: Cross-sectional survey. Objectives: Assessment of subaxial cervical facet injuries using the AO Spine Subaxial Cervical Spine Injury Classification System is based on CT scan findings. However, additional radiological evaluations are not directly considered. The aim of this study is to determine situations in which spine surgeons request additional radiological exams after a facet fracture. Methods: A survey was sent to AO Spine members from Latin America. The evaluation considered demographic variables, routine use of the Classification, as well as the timepoint at which surgeons requested a cervical MRI, a vascular study, and/ or dynamic radiographs before treatment of facet fractures. Results: There was 229 participants, mean age 42.9 ± 10.2 years; 93.4% were men. Orthopedic surgeons 57.6% with 10.7 ± 8.7 years of experience in spine surgery. A total of 86% used the Classification in daily practice. An additional study (MRI/vascular study/and dynamic radiographs) was requested in 53.3%/9.6%/43.7% in F1 facet injuries; 76.0%/20.1%/50.2% in F2; 89.1%/65.1%/28.4% in F3; and 94.8%/66.4%/16.6% in F4. An additional study was frequently required: F1 72.5%, F2 86.9%, F3 94.7%, and F4 96.1%. Conclusions: Spine surgeons generally requested additional radiological evaluations in facet injuries, and MRI was the most common. Dynamic radiographs had a higher prevalence for F1/F2 fractures; vascular studies were more common for F3/F4 especially among surgeons with fewer years of experience. Private hospitals had a lower spine trauma cases/year and requested more MRI and more dynamic radiographs in F1/F2. Neurosurgeons had more vascular studies and dynamic radiographs than orthopedic surgeons in all facet fractures.Publication Protocol for the development of enhanced recovery after surgery (ERAS) recommendations for individuals undergoing surgery for degenerative cervical myelopathy(2025) Treanor, Caroline; Anderson, David; Davies, Benjamin; Chhabra, Harvinder; Hutton,Mike; Venkatraghavan, Laskhmikumar; Lazarus, Jed; Singh, Anoushka; Smith, Kieran; Stubbs, Daniel; Vedantam, Aditya; Zamorano, Juan José; Zipser, Carl; Wainwright, Thomas; Wardropper, Jay; Fehlings, MichaelStudy design: Protocol for the development of enhanced recovery after surgery (ERAS) recommendations for DCM surgery. Objectives: To develop ERAS recommendations in collaboration with the ERAS Society to optimize care for individuals having surgery for degenerative cervical myelopathy (DCM)-the most common type of nontraumatic spinal cord injury. Methods: The study protocol was developed in line with the AGREE II checklist for clinical practice guidelines and the ERAS Society standards for guideline development. A multidisciplinary international guideline development group (GDG) including a representative from the ERAS society, clinical experts in the surgical care of people with DCM, and people with lived experience of having surgery for DCM has been established. The recommendations will follow the GRADE methodology and will therefore include the following steps. 1) Framing the health care questions. 2) Selecting and rating the importance of outcomes for each ERAS candidate interventiont. 3) Summarizing the evidence for each ERAS candidate intervention. 4) Judging the quality of evidence for each ERAS candidate intervention. 5) Judging the strength of the recommendations for each ERAS candidate intervention. 6) Developing recommendations statements for the included ERAS interventions and achieving consensus on the ERAS intervention statements to be included in the final guideline. Following the recommendation statements' development, key stakeholders will be invited to externally review the guidelines. Conclusion: ERAS recommendations for DCM aim to reduce the incidence and severity of adverse events, optimize patient outcomes, improve the efficiency and quality of care, and patients' experience and satisfaction with care.
