[Comparsion of bone setting technique combined with percutaneous vertebroplasty and percutaneous kyphoplasty for the treatment of osteoporotic vertebral compression fractures].

Objective: To explore clinical efficacy of osteoplasty combined with percutaneous vertebroplasty(PVP) and percutaneous kyphoplasty (PKP) alone in treating osteoporosis vertebral compression fractures (OVCFs).

Methods: The clinical data of 80 patients with single-level OVCFs treated from January 2021 to June 2022 were retrospectively analyzed, and were divided into treatment group and control group according to different surgical methods, 40 patients in each group. In treatment group, there were 24 males and 16 females, aged from 60 to 83 years old with an average of (70.43±7.31) years old;bone mineral density ranged from -3.30 to -2.50 SD with an average of(-2.84±0.24) SD;1 patient with T, 4 patients with T, 11 patients with T, 7 patients with L, 7 patients with L, 5 patients with L, 3 patients with L, 2 patients with L;bone setting technique combined with PVP were performed. In control group, there were 27 males and 13 females, aged from 60 to 82 years old with an average of (68.98±6.94) years old;bone mineral density ranged from -3.40 to -2.50 SD with an average of (-2.76±0.23) SD;2 patients with T, 3 patients with T, 13 patients with T, 11 patients with L, 5 patients with L, 3 patients with L, 2 patients with L, 1 patient with L;simple PKP were peformed. Visual analogue scale (VAS) and lumbar Oswestry disability index (ODI) were compared between two groups before operation, 3 days, 3 and 12 months after operation. The changes of local kyphotic angle, vertebral wedge angle and vertebral anterior margin height ratio were compared between two groups before operation, 3 days and 12 months after operation.

Results: All patients were successfully completed operation. Treatment group were followed up from 13 to 22 months with an average of (16.82±2.14) months, and control group were followed up from 13 to 23 months with an average of (16.45±2.56) months. Three patients were occurred bone cement leakage in treatment group, while 1 patient were occurred bone cement leakage and 1 patient occurred sensory disturbance of lower limb skin in control group;there were no significant difference in complications between two groups (>0.05). There were no significant difference in preoperative VAS and ODI between two groups (>0.05). At 3 days after operation, VAS of treatment group 3.68±0.62 was significantly higher than that of control group 4.00±0.72 (<0.05). There were no significant difference in VAS and ODI between two groups at 3 and 12 months after operation (>0.05). There were no significant difference in local kyphotic angle, vertebral wedge angle and vertebral anterior margin height between two groups at 3 days and 12 months after operation (>0.05).

Conclusion: Compared with PKP, bone setting manipulation combined with PVP for the treatment of OVCFs has advantages in early postoperative pain relief. In terms of vertebral height recovery, bone setting manipulation combined with PVP and PKP alone have similar clinical effects.
