Abstract
This study aims to evaluate safety and practicality in clinical application for better guidance of single segmental osteoporotic vertebral compression fractures treatment. From May 2012 to September 2013, a total of 188 cases of patients with fractures, who received different treatment, were incorporated in the study and then divided into: group A (n=59), conventional pusher-type vertebroplasty; group B (n=54), balloon kyphoplasty; group C (n=60), new-type hydraulic delivery vertebroplasty treatment. The overall follow-up rate was 92.02%. Postoperative visual analogue scale (VAS) and Oswestry disability index (ODI) scores were significantly improved more than those of the preoperative scores in the three groups. Bone cement injection volumes in group A were significantly lower than those in group B and group C. Vertebral height recovery rates among groups were obviously different, showing statistical significance. After a year of follow-up, the vertebral height recovery outcome in group A was obviously poorer than that in group B and group C. A poorer outcome in group B was also found when compared with group C. In addition, the vertebral height restoration had a certain degree of loss, with the loss rate of 20.5, 14.0 and 7.5% in the three groups, respectively. Three operation methods have equivalent effects in the improvement of symptoms and functional recovery. Therefore, the new-type hydraulic delivery vertebroplasty provides a relatively more concise operation and shorter operation time, displaying more outstanding performance of clinical efficacy in spinal reconstruction and reduction of complications risks by evaluating the diffusion of the bone cement, vertebral height restoration rate and postoperative complications.
