| Objective:To evaluate the clinical efficacy of percutaneous bipedicularkyphoplasty with double or single balloon in treatment of osteoporosis vertebralcompressive fractures.Methods:From April2008to Feb2010,26patients with osteoporosis vertebralcompressive fracture involving35vertebrae were managed by percutaneous bipedicularkyphoplasty. The single balloon group included2male and13female with an averageage of72.8(range53to79years old). The double balloon group included3male and8female with an average age of70.8(range51to80years old). Each procedure includedinsertion of inflatable balloon(single and double), fracture reduction and cement fillingunder monitoring. Preoperative and postoperative pain level, radiographs andcomplications were recorded and analyzed.Results:All26patients tolerated the operation well. The mean operation timewere37.5min (33～85min) and33.9min (30～75min) for single and double balloongroups respectively; the mean volume of cement injected into one level were5.1ml(3.1～6.5ml) and6.0ml(3.9～7.5ml) for single and double balloon groups respectively.The mean follow-up were14.8months(12～18months). The mean VAS pain score ofsingle balloon group decreased significantly from7.6±2.2preoperatively to2.5±1.8postoperatively (P<0.05) and3.1±2.0at final follow-up, the mean VAS pain score ofdouble balloon group decreased significantly from7.9±2.3preoperatively to2.4±2.0postoperatively (P<0.05) and2.9±2.1at final follow-up, no significant difference wasfound between two groups. Singnificant increase of the mean height of anterior andmedial vertebral body were record after the operation and maintained at final follow-up. The mean correction of local kyphosis was7.0°±4.5°for single balloon group and7.7°±3.9°for double balloon group, no significant difference was found between twogroups.Conclusions:Percutaneous bipedicular kyphoplasty with single or double balloonis effective and relatively safe for osteoporosis vertebral compressive fractures. |
