Application of G arm X-ray machine in minimally invasive treatment of thoracolumbar vertebral osteoporotic vertebral compression fractures

Abstract

Objective To compare the clinical effects of G-arm X-ray machine and C-arm X-ray machine in percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture (OVCF) of thoracolumbar spine. Methods The clinical data of ninety-five patients with thoracolumbar OVCF treated with PKP from May 2016 to August 2017 in Yanan University Affiliated Hospital were retrospectively analyzed.They were divided into two groups according to the different guiding fluoroscopy methods used during the operation.Forty-six cases in G arm group completed PKP under the guidance of G arm X-ray machine, Forty-nine cases in C arm group completed PKP under the guidance of C arm X-ray machine.The operation time, fluoroscopy times, cement leakage cases, the height of injured vertebral leading edge, Cobb angle of kyphosis, visual analogue score and Oswestry dysfunction index were recorded before and after operation, and the related indexes were analyzed and compared. Results Two groups of patients were successfully completed surgery, no complications of vascular and nerve injury.The operation time and fluoroscopy times in G arm group were less than those in C arm group (operation time: (29.6±4.5) min vs.(42.5±5.3) min, and fluoroscopy times in G arm group: (9.1±2.0) vs.(16.9±3.2)); the difference was statistically significant (t=-12.747, 12.870, P 0.05). Conclusion Using G-arm X-ray machine to assist PKP in the treatment of thoracolumbar spine OVCF can effectively shorten the operation time, reduce the intraoperative fluoroscopy time, and the clinical effect is satisfactory.
