Abstract：Objective To compare the efficacy of percutaneous vertebroplasty ( PVP ) and percutaneous kyphoplasty ( PKP ) in the treatment of Kümmell disease. Methods A retrospective analysis of 40 patients with Kümmell disease was conducted from January 2013 to June 2016. There were 12 males and 28 females with an average of ( 72.3 ± 5.4 ) years ( range: 63 - 81 years ). Patients were divided into PVP group ( n = 20 ) and PKP group ( n = 20 ) according to the treatment methods. Operation time, bone cement injection volume, bone cement leakage rate and hospitalization expenses of 2 groups were recorded. Preoperative and postoperative visual analogue scale ( VAS ), Oswestry disability index ( ODI ), anterior vertebral height and kyphosis Cobb's angle were used to evaluate effects. Results All 40 patients completed operations, and were followed up for 10 - 18 months. The operation time ( 34.30 ± 2.00 ) min, the amount of bone cement injection ( 4.27 ± 0.55 ) ml and the cost of hospitalization expenses ( 1.51 ± 0.14 ) million yuan in PVP group were lower than those in PKP group ( 39.10 ± 5.59 ) min, ( 5.21 ± 0.58 ) ml, ( 3.17 ± 0.13 ) million yuan with statistical significance ( P < 0.05 ). The bone cement leakage rate of PVP group ( 25% ) was higher than that of PKP group ( 20% ), but the differences were not statistically significant ( P >0.05 ). PVP group ( preoperatively / 1 day postoperatively / final follow-up ): VAS ( 7.25 ± 0.79 ), ( 3.75 ± 0.85 ), ( 1.90 ± 0.55 ); ODI ( 44.55 ± 5.78 ) %, ( 28.95 ± 5.97 ) %, ( 18.90 ± 2.92 ) %; vertebral height ( 17.48 ± 1.32 ) mm, ( 20.98 ± 1.99 ) mm, ( 20.85 ± 2.04 ) mm; vertebral kyphosis Cobb's angle ( 22.18 ± 3.49 ) °, ( 17.05 ± 3.02 ) °, ( 17.08 ± 3.07 ) °. PKP group ( preoperatively / 1 day postoperatively / final follow-up ): VAS ( 6.95 ± 0.94 ), ( 3.45 ± 0.60 ), ( 1.80 ± 0.52 ); ODI ( 43.60 ± 4.90 ) %, ( 27.65 ± 3.90 ) %, ( 17.95 ± 2.26 ) %; vertebral height ( 17.11 ± 1.92 ) mm, ( 26.00 ± 1.50 ) mm, ( 25.87 ± 1.47 ) mm; vertebral kyphosis Cobb's angle ( 21.65 ± 3.49 ) °, ( 12.02 ± 3.00 ) °, ( 12.09 ± 3.02 ) °. Difference were statistically significant in VAS, ODI, anterior vertebral height and kyphosis Cobb's angle comparing preoperatively and 1 day postoperatively / final follow-up ( P < 0.05 ). There were no statistical differences in the improvement of VAS and ODI between the 2 groups ( P > 0.05 ). The anterior vertebral height and kyphosis Cobb's angle improvement in PKP group at 1 day postoperatively and the final follow-up were better than those in PVP group with statistically significance ( P < 0.05 ). Conclusions For Kümmell disease, both PVP and PKP can effectively alleviate patients' back pain. PVP shortens the operation time, reduces surgical trauma and also the economic burden of patients, but has higher rate of bone cement leakage. PKP can obtain more satisfactory reduction effects.
