Objective To compare the clinical outcomes of percutaneous kyphoplasty(PKP) combined with facet joint blocking in the treatment of elderly singlesegment vertebral compression fracture.Methods A total of 72 patients with singlesegment vertebral compression fractures who were diagnosed in our hospital from January 2018 to January 2019 were randomly divided into the control group and the observation group.PKP and PKP combined with small facet joints were performed in control group and observation group respectively.The pain visual analogue index VAS score and dysfunction index ODI score were used to evaluate the clinical efficacy in preoperative

postoperative immediately

24 hours

72 hours and 1 month.ResultsThe operation time of the observation group was longer than that of the control group

the difference was statistically significant(P<0.05).There was no significant difference between the two groups in the VAS and ODI scores before operation (P>0.05).The VAS and ODI scores were significantly improved compared with those before operation at all postoperative time points

and the difference was statistically significant (P<0.05).The improvement of the observation group was more obvious at postoperative immediately

24 hours and 72 hours than those of control group

the difference was statistically significant(P<0.01)

but there was no significant difference between the two groups at 1 month after surgery(P>0.05).Conclusion PKP combined with facet joint blocking for the treatment of singlesegment vertebral compression fractures in the elderly has better relief of early pain

with the activity earlier

which can significantly improve the surgical outcome and reduce complications.
