Low reoperation rate reported with sequential interbody dilation for cervical kyphosis
Sequential interbody dilation can be an effective and safe technique for the correction of cervical kyphosis and results in low complication and reoperation rates, according to results of this recently published retrospective study.
Researchers analyzed 100 adult patients who underwent sequential interbody dilation between 2006 and 2011. Of the 100 patients, 74 patients had mild preoperative cervical kyphosis (0° to 9°); 19 patients had moderate kyphosis (10° to 19°) and seven patients had severe kyphosis (equal to or greater than 20°). Patients were followed for a mean of 26.8 months.
Investigators found an overall complication rate of 9% and a reoperation rate of 4.7%. There were no patient deaths, and researchers discovered 16% of patients went on to have posterior fusion.
There was a statistically significant correction in cervical alignment in the patient cohort. In addition, investigators found the mean overall kyphosis correction was 12.4°. The severe kyphosis patients experienced the greatest cervical alignment correction, gaining 24.7°. Patients with moderate kyphosis gained 17.8° of correction, and patients with mild preoperative kyphosis had 10.1° of correction. Researchers reported a mean correction of 32° was obtained if five levels were addressed in the patient cohort. – by Robert Linnehan
