ABSTRACT
Objective: To explore the effect of percutaneous kyphoplasty (PKP) on lumbar-pelvic correlation in osteoporotic vertebral compressive fracture (OVCF). Methods: According to the inclusion criteria, 63 patients with primary osteoporosis between January 2012 and June 2017 were selected as the control group and 67 patients with single-segment lumbar OVCF receiving PKP and complete clinical data were included as the observation group. There was no significant difference in gender, age, and lumbar spine bone density between the two groups ( P>0.05). The visual analogue scale (VAS) score and Oswestry Disability Index (ODI) score were used to assess lumbar pain and function before operation and at 3 days after operation in the observation group; lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS) were measured in lumbar lateral X-ray films which were taken before PKP and at 1 month after PKP. The same parameters were measured in the lumbar lateral X-ray films which were taken at the time of initial diagnosis in the control group. Results: All patients were followed up 3-24 months with an average of 5.8 months in the observation group. The VAS score decreased from 5.6±1.8 before PKP to 2.8±1.3 at 3 days after PKP ( t=14.082, P=0.000); ODI decreased from 50.1%±5.0% before PKP to 18.2%±1.8% ( t=47.011, P=0.000). Compared with the control group, the LL, PI, and SS decreased and the PT increased in the observation group, and only the difference in LL between the two groups was significant ( P0.05). In the control group, LL was positively correlated with PI and SS ( P<0.05); PI was positively correlated with PT and SS ( P<0.05). In the observation group, PI was positively correlated with SS ( P<0.05) before and after PKP. Conclusion: OVCF patients lost the specific lumbar-pelvic correlation. PKP can restore lumbar lordosis, but it still can not restore the normal physiological fitting.

ABSTRACT
[Objective]To analyze the therapeutic effects of percutaneous kyphoplasty for acute versus chronic osteoporotic vertebral compressive fracture.[Method]Percutaneous kyphoplasty was performed in 56 patients(137 vertebraes) with osteoporotic vertebral compression fracture (VCF).Based on the changes on MRI,all compression fractures were divided into 3 types:acute VCF,repairing VCF and chronic VCF.Types were examined for differences in treatment efficacy,according to the anterior/middle vertebral body height,Cobb's angle and visual analogue scale(VAS) at pre-and post-operation.[Result]All patients with the VCFs had rapid and significant improvement in back pain following percutaneous kyphoplasty.VAS was from 8.09?1.12 preoperatively to 2.31?0.91 postoperatively,and 2.26?0.88 at final follow-up.The results showed that 41 cases were Type Ⅰ on MRI,69 were Type Ⅱ and 27 were Type Ⅲ.Significant improvement was observed at the post-operative versus pre-operative assessments in Type Ⅰ and Type Ⅱ.No significant differences were observed between post-and pre-operative assessments in Type Ⅲ.[Conclusion]The curative effect of percutaneous kyphoplasty for the treatment of acute VCFs appears superior to that of chronic VCFs.After a definite diagnosis of VCFs,percutaneous kyphoplasty should be performed as early as possible in order to obtain a better therapeutic effect.
