| 【Abstract】 Objectives: To summarize the clinical outcome of self-making working tube and its orientation controlling in percutaneous kyphoplasty(C-PKP) for osteoporotic vertebral compression fracture(OVCF). Methods: Modified C-PKP was designed to have a 2cm of sleeve tail shaped as arc and slope, which could control the expansion direction though adjusting the working tube. From December 2010 to December 2013, 43 patients with thoracolumbar OVCF were treated by modified C-PKP, at the same time, 48 cases experienced conventional PKP, the two groups were compared in age, sex, bone density, compressional degree(P＞0.05). The visual analogue scale(VAS) score, the correction of wedge angle and the kyphotic angle of the injured vertebra before operation, 3 days and 6 months after operation and the postoperative cement leakage were compared between two groups. Results: All the operations were performed successfully. There were 8 cases suffering from cement leakage during operation in the traditional PKP, type C was noted in 6 cases, type B in 1 case, type S in 1 case, but no radicular symptom was noted. C-PKP had significant less rate of cement leakage than PKP(P<0.05). The patients were followed up for 11.3±5.2 months(6-35 months). There were significant differences between the preoperative and postoperative VAS scores, the correction of wedge angle and the kyphotic angle of the injured vertebra in two groups at each follow-up time point(P＜0.05), but there were no significant differences between two groups at the same time point(P>0.05). Conclusions: C-PKP is an efficient way for thoracolumbar OVCF, which can decrease the incidence of cement leakage. |
