The results showed significant improvements in the VAS score, ODI score, and vertebral height restoration in each group ( p 0.05). The mean age, sex, body mass index, injury time, segmental distribution, and morphological classification of fractures before surgery did not differ significantly between the groups. Visual pain analog scale (VAS) and Oswestry Disability Index (ODI) were calculated before surgery, immediately post-surgery, and 2 years after surgery. Cement leakage, height restoration, and cement distribution were calculated from the radiographs.

Patient characteristics, surgical outcomes, operation time, blood loss, clinical and radiological features, and complications were compared between two groups. We retrospectively reviewed the records of 160 patients who underwent percutaneous kyphoplasty for lower lumbar (元–L5) osteoporotic vertebral compression fractures between January 2016 and January 2020. Here, we compared the clinical and radiological results of unipedicular and bipedicular approaches for percutaneous kyphoplasty for treating osteoporotic vertebral compression fractures. However, most studies have reported thoracolumbar fractures, with few reports describing the treatment of the lower lumbar spine. Unipedicular and bipedicular approaches for percutaneous kyphoplasty are reportedly both effective in treating osteoporotic vertebral compression fractures (OVCFs).
