Publication Mechanical Instability After Civilian Thoracolumbar Gunshot Injuries: A Systematic Review to Support Classification Development(2025) Ricciardi, Guillermo; Cirillo, Ignacio; Cabrera, Juan; Alvarenga, Otávio; Neves, Emiliano; Carazzo, Charles; Dittmar, Michael; Guiroy, Alfredo; Yurac, Ratko; Schroeder, GregoryStudy DesignSystematic Review.ObjectivesIdentify risk factors for mechanical instability in thoracolumbar gunshot wounds to develop a new classification system.MethodsA systematic review following PRISMA 2020 guidelines was conducted across multiple databases from January 1, 1990, to September 12, 2024 (PROSPERO: CRD42023458804).ResultsOf 2400 records, 33 studies (3195 patients) met inclusion criteria, mostly retrospective and single-center, with varying definitions of instability. Direct comparison was limited due to clinical heterogeneity. Only 12 studies defined mechanical instability, mainly using the Denis three-column theory. Instability was reported in less than 10% of cases, except for one higher-rate outlier. The main markers included vertebral body comminution and potential ligamentous injury. Management was mainly conservative, with a low fixation rate (1.5-9.7%). Imaging relied on CT and static X-rays, with some studies advocating for dynamic radiographs.ConclusionThere is a lack of standardized definitions for mechanical instability in civilian thoracolumbar gunshot injuries. Four recurrent unstable patterns were detected, with vertebral body comminution as the most consistent marker. The need for a standardized classification system and further prospective studies is evident.
