Abstract: BACKGROUND: Clinical therapies of osteoporotic vertebral compression fracture have two different approaches, including unilateral pedicle extrapedicle and bilateral pedicle approach of percutaneous vertebroplasty, but there were fewer reports about postoperative bone cement leakage rate and security in the two approaches.
OBJECTIVE: To compare postoperative bone cement leakage rate and security with osteoporotic vertebral compression fracture by two different approaches, unilateral pedicle extrapedicle and bilateral pedicle approach of percutaneous vertebroplasty.  
METHODS: This study enrolled 60 cases with the osteoporotic vertebral compression fracture who were patients meeting the inclusion criteria in the First Affiliated Hospital of Hebei North University from January 2018 to December 2020. The 60 cases were randomly divided into two groups according to surgical approach. Group A (n=30) was treated with unilateral pedicle extrapedicle approach of percutaneous vertebroplasty. Group B (n=30) was treated with bilateral pedicle approach of percutaneous vertebroplasty. The volume of bone cement injection, bone cement leakage rate and other complications, as well as kyphosis angle of the compressive vertebral body, the visual analogue scale score, and Oswestry disability index were compared between the two groups.
RESULTS AND CONCLUSION: (1) There was no statistical significance in the volume and leakage rate of bone cement injection in two groups (P > 0.05). (2) Visual analogue scale score and Oswestry disability index were significantly lower at 1, 3 days, and 1 month after surgery compared with that preoperatively in both groups (P < 0.05). Postoperative kyphosis angle of the compressive vertebral body was less than that preoperatively (P < 0.05). There was no statistical difference in visual analogue scale score, Oswestry disability index, and kyphosis angle at various time points after surgery in both groups (P > 0.05). (3) The results suggest that satisfactory clinical effect can be obtained by two different approaches, unilateral pedicle extrapedicle and bilateral pedicle approach of percutaneous vertebroplasty.
