Application of operation bed and C-arm digital metrology adjustment in the percutaneous vertebroplasty for osteoporotic thoracolumbar vertebral fractures

Abstract

To explore the application effect of operation bed and C-arm digital metrology adjustment in percutaneous vertebroplasty for osteoporotic thoracolumbar vertebral fractures. Ninty-four patients with osteoporotic thoracolumbar vertebral fractures admitted to our hospital from February 2015 to February 2017 were divided into control group and observation group according to random number table method, with 47 cases in each group. Control group adjusted C-arm and operating bed based on experience. For observation group surgical bed and C arm were measured and adjusted digitally and metrologically during percutaneous vertebroplasty. The operation time, times of fluoroscopy, hidden blood loss and bone cement volume were recorded in two groups. The clinical efficacy of two groups was observed by visual analogue score (VAS) and Oswestry Disability Index(ODI). Cobb angle and height of injured vertebrae before and after surgery were analyzed by imaging data. The operation time, times of fluoroscopy, and hidden blood loss were significantly lower in observation group than in control group (P<0.05), but there was no significant difference in bone cement volume between two groups (P>0.05); VAS and ODI of observation group were significantly lower than that of the control group(P<0.05); there was no significant difference in Cobb angle and height of injured vertebrae before and after operation between two groups. There were 3 cases of cement leakage, 1 case of urinary tract infection, 1 case of pulmonary infection, 2 cases of bedsore in observation group with complication rate was 14.89%(7/47); there were 8 cases of cement leakage, 2 cases of spinal nerve injury, 1 case of urinary tract infection, 3 cases of pulmonary infection, 2 cases of bedsore in control group with complication rate was 34.04% (16/47). The incidence of complications in observation group was significantly lower than that of control group (P<0.05). Operation bed and C-arm digital metrology adjustment can improve the surgical effect in percutaneous vertebroplasty for osteoporotic thoracolumbar vertebral fractures and promote rapid recovery.
