Abstract:

Objective
To investigate the clinical effect of percutaneous kyphoplasty(PKP) for curring osteoporotic thoracolumbar fracture.Methods The clinical data of 126 patients with osteoporotic thoracolumbar fracture were retrospectively analyzed.The patients were treated with PKP.The clinical effect was assessed by visual analogue scale (VAS) and  oswestry disability index (ODI).The  vertebral height  and  kyphotic angle were measured in  X-rays  plain-film. Results All patients were followed up  10 to 24 months with an average of 18 months.The VAS scores  of the  patients before operation,24 h after operation,and at final follow-up  were 7.9±1.2,3.2±1.1,and  2.1±0.8;the ODI were 83.7±4.9,33.2±3.9,and 27.8±3.6.respectively.The vertebral heights were (18.2±3.2) mm,(25.8±3.1) mm,and (24.9±3.2) mm,respectively; the  kyphotic angles were 17.2°±3.2°,8.4°±3.1°,and  9.1°±3.1°,respectively.There were significant differences of   all four indexes between  24 h after operation,6 months after operation,final follow-up and before operation（P<0.05）,but there were no significant differences of all four indexes between 24 h after operation,  6 months after operation and final follow-up（P＞0.05）.Conclusion PKP  is effective for treatment of osteoporotic thoracolumbar fracture,which can expeditiously relieve pain and effectively recover the  vertebral height  and kyphotic angle.
