CHICAGO — Unipedicular balloon kyphoplasty can yield clinical and radiographical results similar to bipedicular balloon kyphoplasty while reducing operative time, according to a study presented here by Brian J. Rebolledo, BA, at the 2011 Annual Meeting of the North American Spine Society .
“We showed that unipedicular kyphoplasty is a safe and effective procedure that provides equivalent results in both self-reported and clinical outcome measures, as well as radiographic outcomes,” Rebolledo said. “In addition, unipedicular kyphoplasty has a shorter operative time and can reduce operative costs.”
Rebolledo and colleagues performed a prospective, randomized study of 40 patients aged 50 years or older who had vertebral compression fractures between July 2006 and Dec. 2008. Investigators randomized 20 patients with 25 vertebral compression fractures to receive unipedicular balloon kyphoplasty, and the other 20 patients with 27 vertebral compression fractures to undergo bipedicular balloon kyphoplasty.

Clinical measures were used to determine overall improvement in patients from each cohort, and investigators collected data preoperatively and at 3 months and 12 months postoperatively. Radiographs were also taken pre- and postoperatively to determine Cobb angle differences. Operative time and any incidence of cement leakage were also recorded.
“Across the board, baseline data for both groups were not different,” Rebolledo said. “Both groups had significant improvements at 3 months postoperatively, and these improvements were sustained 12 months postoperatively.”
Rebolledo noted there were no between-group differences in any of the clinical outcome measures at any time point. He added that the use of unipedicular balloon kyphoplasty resulted in shorter operative time, with unipedicular yielding a mean operative time of 47 minutes and bipedicular yielding an operative time of 71 minutes.
