Abstract:

Objective

To compare the results of percutaneous kyphoplasty (PKP) versus conservative treatment for intravertebral cavity formation secondary to osteoporotic burst fractures.

Methods

From June 2007 to February 2013, 84 patients who suffered from osteoporotic vertebral burst fracture without neurologic deficit were enrolled in this study. Of them, 42 patients were treated by PKP (the PKP group) , while the other 41patients received conservative treatment alone (the conservative group) with matched age, gender, involved level, and the type of fracture between the two groups. The visual analogue scale (VAS) , deformity index, antero-posterior height ratio and its improvement rate, activity capacity grade were used for assessment of the outcome at 6 and 12 months after treatment.

Results

No infection and pulmonary embolism occurred in any patient. Although limited cement leakage was noted in 14 patients of the PKP group, including front of vertebral body in 6,into disc in 4 and into vertebral canal in 4, no clinical symptom occurred in anyone of them. All of the 84 patients were followed up from 12 to 24 months with an average of 22.1 months. At 12 months after treatment, the PKP group was scaled significantly lower mean VAS than the conservative group (0.88 versus 2.52, P=0.001) , while the former was significantly higher than the latter in the activity capacity grade P=0.002 ) . Additionally, the PKP group was significantly inferior to the conservative group in the mean deformity index (1.41 versus 1.72, P<0.001) , whereas the former was significantly superior to the latter in the mean recovery rate of vertebral height (+16.15% versus -24.28%, P<0.001) with the anteroposterior height ratio (71.96% versus 49.94%) .

Conclusion

Percutaneous kyphoplasty provided better clinical and radiological results than the conservative treatment for patients with osteoporotic burst fracture.
