Comparison between Percutaneous Kyphoplasty and Posterior Fixation Combined with Vertebroplasty in the Treatment of Stage III Kümmell’s Disease without Neurological Deficit

<div>Images of a 77-year-old female patient. (a, b) Preoperative radiograph, manifesting the collapsed vertebra. The red line shows the Cobb angle was 11°, and the white line and the black line refers to anterior and central vertebral height, respectively. The ratio of anterior vertebral height (RAVH) was 21.4%, and the ratio of central vertebral height (RCVH) was 22.9%. (c) Preoperative CT showed the collapsed posterior wall and intravertebral cleft. (d) Preoperative MRI showed the spinal compression. (e–g) Postoperative images: the Cobb angle recovered to 8°, the RAVH was 32.5%, and the RCVH 33.4%.</div>
