Abstract：Objective To compare the clinical efficacy of percutaneous vertebroplasty(PVP)and percutaneous kyphoplasty(PKP)in the treatment of stage Ⅰ and stage Ⅱ Kümmell's disease.Methods The clinical data of patients with stage Ⅰ and stage Ⅱ Kümmell's disease who were treated with PVP(25 cases)and PKP(21 cases)in our hospital from January 2018 to June 2022 were retrospectively analyzed.The basic data,bone cement leakage rate,and incidence of adjacent vertebral fractures were compared.The visual analogue score(VAS)and Oswestry Disability Index(ODI)were used as clinical evaluation indicators.The height of the vertebral anterior edge and the kyphotic angle were measured by imaging examination,and the vertebral compression rate and kyphotic correction rate were calculated.Results Both groups were followed up for 12-20 months.The amount of bone cement injected in the PKP group was(5.50±0.74)ml,and that of the PVP group was(4.80±0.51)ml,P<0.05.There were 2 cases of bone cement leakage in the PKP group and 6 cases in the PVP group,P<0.05.There were 3 cases of adjacent vertebral fractures in the PKP group and 1 case in the PVP group,P<0.05.There was no refracture of the responsible vertebra and displacement of bone cement in both groups at the last follow-up.VAS and ODI in both groups were significantly lower than those before surgery at 1 day,3 months,and 1 year after surgery(all P<0.05).The vertebral compression rate and kyphosis correction rate of the PKP group were better than those of the PVP group 1 day,3 months,and 1 year after surgery(all P<0.05).Conclusions Both PVP and PKP can achieve good clinical outcomes in the short term for the treatment of stage Ⅰ and stage Ⅱ Kümmell disease.PVP has the advantages of shorter operation time and fewer radiation exposures,while PKP has a lower cement leakage rate and better effects in restoring vertebral height and correcting kyphosis,but it may increase the risk of adjacent vertebral fractures.The choice of surgical procedure should be determined based on a comprehensive evaluation of the patient's overall condition,degree of vertebral compression and kyphosis deformity,economic conditions,and surgical willingness.
