Abstract:
OBJECTIVETo analyze the advantages and disadvantages of bipedicular approach and uni-extrapedicular approach of vertebroplasty in treating osteoporotic vertebral compression fractures (OVCFs).
METHODSFrom January 2008 to December 2010,53 patients with OVCFs were retrospectively analyzed. There were 24 males, 30 females with an average age of 66.9 years (ranged,59 to 88 years). Among them, 26 cases were treated with bipedicular approach, 28 cases were treated with uni-extrapedicular approach. The data of bone cement injection, radiology exposure times, operation time, bone cement leakage and vessels nerve complications were observed. Cobb angle, vertebral compression ration were observed by imaging data, and evaluate recovery of deformity.
RESULTSThe data of bone cement injection, radiology exposure times, operation time, VAS score were (6.6 +/- 0.8) ml and (6.8 +/- 1.5) ml, (21.7 +/- 4.0) times and (17.9 +/- 3.6) times, (40.5 +/- 5.5) min and (31.6 +/- 9.1) min, (2.8 +/- 0.6) scores and (3.1 +/- 0.5) scores respectively. Cobb angle,vertebral compression ration were (7.6 +/- 2.0) degrees and (6.9 +/- 2.6) degrees, (18.1 +/- 5.8)% and (16.5 +/- 6.1)%. There were no vascular nerve complications occurred. For bone cement leakage, 3 cases (11%) in bipedicular approach and 3 cases (11%)in uni-extrapedicular approach. There was no significant differences between two groups in VAS score, recovery of vetebral body, Cobb angle, bone cement injection and bone cement leakage, but had significant differences in radiology exposure times and operation time (P<0.05).
CONCLUSIONBoth of two approaches can treat OVCFs well, especially extropedicle approach which could reduce operation time and radiation shoot frequency.
