Publication Streamlining the Journey of Research Into Clinical Practice: Making Your Patients and Practice Flourish Optimizing Management and Minimizing Risk of Osteoporotic Vertebral Fractures - Perspectives of the AO Spine KF Trauma and Infection Group Key Opinion Leaders(2024) Joaquim, Andrei; Bigdon, Sebastian; Bransford, Richard; Chhabra, Harvinder; Yurac, Ratko; Kumar, Vishal; El-Sharkawi, Mohammad; Benneker, Lorin; Karamian, Brian; Canseco, Jose; Scherer, Julian; Hassan, Ahmed; Schroeder, Gregory; Öner, Cumhur; Rajasekaran, Shanmuganathan; Vialle, Emiliano; Kanna, Rishi; Vaccaro, Alexander; Tee, Jin; Camino, Gaston; Fisher, Charles; Dvorak, Marcel; Schnake, Klaus; AO Spine Knowledge Forum Trauma & InfectionStudy design: Literature review with clinical recommendations. Objective: To highlight important studies about osteoporotic spinal fractures (OF) that may be integrated into clinical practice based on the assessment of the AO Spine KF Trauma and Infection group key opinion leaders. Methods: 4 important studies about OF that may affect current clinical practice of spinal surgeons were selected and reviewed with the aim of providing clinical recommendations to streamline the journey of research into clinical practice. Recommendations were graded as strong or conditional following the GRADE methodology. Results: 4 studies were selected. Article 1: a validation of the Osteoporotic Fracture (OF)-score to treat OF fractures. Conditional recommendation to incorporate the OF score in the management of fractures to improve clinical results. Article 2: a randomized multicenter study comparing romosozumab/alendronate vs alendronate to decrease the incidence of new vertebral fractures. Strong recommendation that the group receiving romosozumab/alendronate had a decreased risk of new OF when compared with the alendronate only group only. Article 3: a systematic literature review of spinal orthoses in the management of. Conditional recommendation to prescribe a spinal orthosis to decrease pain and improve quality of life. Article 4: post-traumatic deformity after OF. A conditional recommendation that middle column injury and pre-injury use of steroids may lead to high risk of post-traumatic deformity after OF. Conclusions: Management of patients with OF is still complex and challenging. This review provides some recommendations that may help surgeons to better manage these patients and improve their clinical practice.Publication Variations in management of A3 and A4 cervical spine fractures as designated by the AO Spine Subaxial Injury Classification System(2022) Sheen Kweh, Barry Ting; Wee Tee, Jin; Muijs, Sander; Oner, Cumhur; Schnake, Klaus John; Benneker, Lorin Michael; Neves Vialle, Emiliano; Kanziora, Frank; Rajasekaran, Shanmuganathan; Schroeder, Gregory; Vaccaro, Alexander R.; AO Spine Subaxial Injury Classification System Validation Group; Grin, Andrey; Abdelgawaad, Ahmed Shawky; Zubairi, Akbar Jaleel; Castillo, Alejandro; Vernengo Lezica, Alejo; Ramieri, Alessandro; Guiroy, Alfredo; Grundshtein, Alon; Godinho Jr., Amauri; Henine, Amin; Pershin, Andrei A.; Athanasiou, Alkinoos; Zarate-Kalfopulos, Baron; Benzarti, Sofien; Bernucci, Claudio; Rebholz, Brandon J.; Direito-Santos, Bruno; Lourenço Costa, Bruno; Saciloto, Bruno; Majer, Catalin; Tannoury, Chadi; Cheng, Cristina; Yin Cheung, Jason Pui; Konrads, Christian; Jetjumnong, Chumpon; Chung, Chun Kee; Popescu, Eugen Cezar; Kilinçer, Cumhur; Yurac, RatkoOBJECTIVE Optimal management of A3 and A4 cervical spine fractures, as defined by the AO Spine Subaxial Injury Classification System, remains controversial. The objectives of this study were to determine whether significant management variations exist with respect to 1) fracture location across the upper, middle, and lower subaxial cervical spine and 2) geographic region, experience, or specialty. METHODS A survey was internationally distributed to 272 AO Spine members across six geographic regions (North America, South America, Europe, Africa, Asia, and the Middle East). Participants’ management of A3 and A4 subaxial cervical fractures across cervical regions was assessed in four clinical scenarios. Key characteristics considered in the vignettes included degree of neurological deficit, pain severity, cervical spine stability, presence of comorbidities, and fitness for surgery. Respondents were also directly asked about their preferences for operative management and misalignment acceptance across the subaxial cervical spine. RESULTS In total, 155 (57.0%) participants completed the survey. Pooled analysis demonstrated that surgeons were more likely to offer operative intervention for both A3 (p < 0.001) and A4 (p < 0.001) fractures located at the cervicothoracic junction compared with fractures at the upper or middle subaxial cervical regions. There were no significant variations in management for junctional incomplete (p = 0.116) or complete (p = 0.342) burst fractures between geographic regions. Surgeons with more than 10 years of experience were more likely to operatively manage A3 (p < 0.001) and A4 (p < 0.001) fractures than their younger counterparts. Neurosurgeons were more likely to offer surgical stabilization of A3 (p < 0.001) and A4 (p < 0.001) fractures than their orthopedic colleagues. Clinicians from both specialties agreed regarding their preference for fixation of lower junctional A3 (p = 0.866) and A4 (p = 0.368) fractures. Overall, surgical fixation was recommended more often for A4 than A3 fractures in all four scenarios (p < 0.001). CONCLUSIONS The subaxial cervical spine should not be considered a single unified entity. Both A3 and A4 fracture subtypes were more likely to be surgically managed at the cervicothoracic junction than the upper or middle subaxial cervical regions. The authors also determined that treatment strategies for A3 and A4 subaxial cervical spine fractures varied significantly, with the latter demonstrating a greater likelihood of operative management. These findings should be reflected in future subaxial cervical spine trauma algorithms.
