Objective To discuss the advantages of postoperative early ambulation for patients after high-viscosity bone cement injection treatment for osteoporotic vertebral compression fracture.Methods A total of 42 patients with osteoporotic vertebral compression fracture were divided into the study group (n=21)and the control group (n=21).High-viscosity bone cement injection was used to perform percutaneous vertebroplasty for the patients in the study group,while low-viscosity bone cement injection was adopted to complete percutaneous vertebroplasty for the patients in the control group.The patients of the study group were asked to get out of bed in 4 hours after vertebroplasty and to do off-bed activity in 8 hours after vertebroplasty,while the patients of the control group were asked to get out of bed in 12 hours after vertebroplasty and to do off-bed activity in 24 hours after vertebroplasty.CT reexamination was performed within 3 days after vertebroplasty to observe the paravertebral leakage and the cement distribution in vertebrae.The visual analogue scale (VAS),the ability score of daily life activy (Barthel),the risk score of pressure skin ulcer (Braden) and the risk rating of deep venous thrombosis were used to evaluate the clinical effectiveness for both groups.Results The procedure of vertebroplasty was successfully accomplished in all patients of both groups.No statistically significant differences in VAS score and in Barthel score at 24 hours and 7 days after vertebroplasty existed between the two groups (P＞0.05).Eight days after vertebroplasty,the differences in Barthel score,Braden score and the risk rating of deep venous thrombosis between the two groups were statistically significant (P＜0.05),although the difference in VAS score between the two groups was not statistically significant.Conclusion In treating osteoporotic vertebral compression fracture by using high-viscosity bone cement injection,postoperative early ambulation can effectively improve the patient's daily activities,reduce the risk of the formation of pressure skin ulcer and deep vein thrombosis,thus,reduce the nursing workload for both nurses and patient's family members.(J Intervent Radiol,2017,26:749-752).
