    Preoperative paraspinal muscle quality, measured by fat infiltration, influences long-term radiographic outcomes after open pedicle screw fixation for thoracolumbar fractures.

  • 2

    Patients with lower fat infiltration in paraspinal muscles showed better muscle parameters and maintained radiographic correction at one year post-surgery.

  • 3

    The high-fat group experienced greater loss of correction in vertebral body angle and regional kyphosis angle, particularly in unstable fracture patterns.

  • 4

    No significant differences were observed in clinical efficacy scores or complication rates between the low-fat and high-fat groups postoperatively.

  • 5

    Assessing paraspinal muscle quality preoperatively may serve as a valuable prognostic tool for surgical planning and patient counseling.
