Effect of robot-assisted percutaneous vertebroplasty through interverte-bral foramen in the treatment of severe compression Kummell's disease
Objective To investigate the clinical effect of robot-assisted percutaneous vertebroplasty through intervertebral foramen in the treatment of severe Kummell's disease.Methods From September 2020 to October 2022,21 patients with severe compressed Kummell's disease who underwent robot-assisted percutaneous vertebroplasty through intervertebral foramen in Department of Spinal Surgery,Dalian Second People's Hospital were selected.The intraoperative blood loss,the time of operation,the amount of bone cement in intravertebral vacuum cleft injected into the vertebra,the leakage of bone cement,and the occurrence of complications were observed.Patients were followed up for six to nine months,and visual analogue scale(VAS)score,Oswestry disability index(ODI),and Cobb angle were observed before surgery,one day after operation,and at the last follow-up.Results The intraoperative blood loss of 21 patients was＜5 ml,the operative time was(34.5±7.6)min,and the injection volume of bone cement was(2.4±0.3)ml;no bone cement leakage,and no complications such as nerve and spinal cord injury.VAS score and ODI were lower than those before surgery at the last follow-up(P＜0.05).There were no significant differences in Cobb angle between one day after operation,at the last follow up and before operation.Conclusion Robot-assisted percutaneous vertebroplasty through intervertebral foramen is a safe and effective treatment for severe compression Kummell's disease.
