Osteoporotic vertebral compression fracture (OVCF) is a kind of fragility fracture, and osteoporotic thoracolumbar fracture (OTLF) is the most common type. At present, OTLF has gradually been a common disease in the elderly, among which improper treatments may cause serious complications and even death, bringing a heavy burden to the family and society. Accordingly, in-depth researches on the prevention and treatment of this disease is significant to improve the quality of life for the elderly and reduce social burden. Accurate choices of treatments depend on fracture classifications. A variety of OTLF classifications have been proposed by domestic and foreign scholars, but each has its own defects, and to distinguish their differences may be problematic. Therefore, it is difficult to apply each classification. In this study, the authors review the research progress in different classification and scoring sytems for OTLF to provide a reference for clinical diagnosis and treatment.
