Percutaneous kyphoplasty treatment of osteoporotic vertebral compression fracture under the guidance of G-arm X-ray machine

Objective To explore the clinical application value of percutaneous kyphoplasty (PKP) under the guidance of G arm X ray machine in the treatment of osteoporotic vertebral compression fracture (OVCF). Methods The medical records of eighty-two patients (94 vertebral bodies) with OVCF treated with PKP were collected retrospectively.Thirty-nine cases (44 vertebral bodies) were guided by G-arm X-ray machine to implement PKP, which were recorded as G-arm group.Forty-three cases (50 vertebral bodies) were guided by C-arm X-ray machine to carry out PKP, which were recorded as C-arm group.The operation time, intraoperative fluoroscopy times, bone cement leakage cases, preoperative and postoperative anterior height of injured vertebrae, Cobb angle of injured vertebrae, visual analogue scale scores and Oswestry disability index of the two groups were recorded. Results There was significant difference in operation time and intraoperative fluoroscopy times between the G-arm group and C-arm group (the operation time: (31.6±5.2) vs.(45.8±6.7) min, the intraoperative fluoroscopy times: (9.5±2.3) times vs.(18.7±3.5) times, t=-10.64, -13.91, P 0.05). Compared postoperative and preoperative anterior height of injured vertebrae, Cobb angle of injured vertebrae, visual analogue scale scores and Oswestry disability index scores of G-arm group and C-arm group respectively, the differences were significant( t=-3.41 vs.-3.28, 6.67 vs.7.66, 26.63 vs.25.75 and 10.41 vs.11.90, P 0.05). Conclusion The treatment of OVCF with PKP guided by G-arm X-ray machine could significantly shorten operation time, reduce the intraoperative fluoroscopy times and the operative difficulty, and increase operation safety than PKP guided by traditional C-arm X-ray machine.
