A modified MRI protocol for the increased detection of sacrococcygeal fractures in patients with thoracolumbar junction fractures

A modified MRI protocol for the increased detection of sacrococcygeal fractures in patients with thoracolumbar junction fractures

Abstract This study aimed to identify concurrent thoracolumbar junction (TLJ) and sacrococcygeal (SC) fractures using a modified MRI protocol and analyze the risk factors associated with tandem fractures. We retrospectively investigated patients with MRI-confirmed TLJ fractures from January 2017 to...
