Clinical research of percutaneous kyphoplasty in the treatment of osteoporotic vertebral fractures

Objective To investigate the clinical efficacy of percutaneous kyphoplasty(PKP) on osteoporotic vertehral compressive fractures.Methods 136 patients(256 vertebrals) with osteoporotic vertebral compression fractures from July 2007 to September 2011 in Department of Orthopedics of the Central Hospital of Jiangmen City were selected and treated with PKP.Visual analogue scale(VAS) method was used to assess the pre-and post-operative pain symptoms.Furthermore,vertebral height and the clinical complication were observed.Results All the cases were followed-up for 3-28 months,the average were 12 months;all the pain symptoms were found eased,the VAS score after operation(2.89±1.40) scores was lower than that before operation(9.12±4.00) scores,the difference was statistically significant(P 0.05);vertebral body height were found recovered,anterior vertebral height before operation were(14.28±2.43) mm,anterior vertebral height after operation were(20.51±2.26) mm,posterior vertebral height before operation were(22.18±2.12) mm,posterior vertebral height after operation were(23.49±2.35) mm,the differences were all tatistically significant(P 0.05);all the cases are performed successfully,10 cases of bone cement leakage were found,8 cases of leakage were found in the vertebral body side,2 cases of leakage were found in the posterior vertebral,no neurologic symptom was found;3 cases.Conclusion PKP is a safe and effective method for treating osteoporotic vertebral fractures.It can rapidly release the backache,restore the body height of fractured vertebrae,improve the life quailty of patients with less clinical syndromes.
