Correctly distinguishing acute from chronic fractures is clinically important because treatment strategies and management decisions differ depending on fracture chronicity. However, differentiating acute and chronic osteoporotic vertebral compression fractures based on imaging findings alone can be challenging in routine clinical practice.\n\nThis retrospective study aims to develop an intelligent diagnostic system based on computed tomography (CT) images to differentiate acute and chronic osteoporotic vertebral compression fractures. Clinical and imaging data from patients diagnosed with osteoporotic vertebral compression fractures will be collected from the First Affiliated Hospital of Chongqing Medical University and an additional medical center. A deep learning model will be trained to automatically analyze CT images and classify fractures as acute or chronic.\n\nThe results of this study may help improve the accuracy and efficiency of fracture chronicity assessment using CT images and provide supportive information for clinical decision-making regarding treatment selection in patients with osteoporotic vertebral compression fractures.",[63],"Osteoporotic Vertebral Compression Fractures",[65,66],"Osteoporotic vertebral compression fracture","Deep learning","NOT_YET_RECRUITING","2025-12-26",{"date":70,"type":71},"2025-12-31","ACTUAL",{"date":73,"type":59},"2025-12-16",{"date":75,"type":59},"2026-01-15",{"name":39,"class":6},1]
