Abstract

Background: Vertebroplasty that is performed in the upper and middle thoracic spine presents technical challenges that are different from those in the lower thoracic or lumbar region due to the small pedicle size and angular severity for thoracic kyphosis. We report the results of percutaneous vertebroplasty and review its effectiveness in treating intractable osteoporotic compression fractures in the upper and middle thoracic spine. Methods: Patients who underwent vertebroplasty due to painful osteoporotic compression fractures at T3 T8 were retrospectively analyzed. The compression rate, volume of injected cement, clinical outcome (VAS score) and complications were analyzed. Results: Forty-three vertebral bodies from 41 patients (32 females and 9 males, age from 64 to 78 years old) underwent vertebroplasty. The mean compression rate improved from 35% to 17%. Bipedicular injections of bone cement were performed at 3 levels of 2 patients, and unipedicular injections were performed in 40 levels of 39 patients. The mean VAS score prior to surgery was 7.7, which improved to 2.4 within 48 hours after surgery, and the mean VAS score after 6 months was 1.5, which was significantly lower. All patients recovered uneventfully, and the neurological examination revealed no deficits. Cement leakage to the adjacent disc (9 levels) and paravertebral soft tissues (10 levels) developed. However, there were no significant complications related to the procedure such as a pneumothorax or pulmonary embolism. Conclusions: Transpedicular vertebroplasty is a safe and effective treatment for the upper and middle thoracic regions, and has a low complication rate.
