Abstract: Objective To study the effect of percutaneous kyphoplasty(PVP)in osteoporotic vertebral compression fractures(OVCF)with vertebral splitting sign．MethodsA total of 96 patients with osteoporotic thoracolumbar vertebral compression fractures underwent PVP were analyzed retrospectively from May 2014 to May 2016．All cases were divided into vertebral splitting group(n=32)and non-splitting group(n=64)according to OVCF with concomitant vertebral splitting or not．The clinical efficacy，pain visual analog scale，Oswestry dysfunction index，the relative height of the anterior vertebrae of the enrolled vertebrae，the angle of the Cobb of the injured vertebrae，the amount of bone cement injected，the distribution of the cement and the leakage rate of cement were compared between the two groups．ResultsThe effective rate was 96．2% and 90．6% respectively in the vertebral splitting group and non-splitting group 1 month after the PVP，and there was no statistical difference between the two groups(P ＞0．05)．The VAS and ODI were decreased，and the Cobb angle and the relative height of anterior injured vertebrae were improved after the operation than those before operation in both groups(P ＜0．05)．However，there was no statistical difference in post-operative VAS，ODI，Cobb angle and relative height of anterior injured vertebrae between the two groups(P ＞0．05)．The injected amount of bone cement was lower i n non-splittinggroup than that in splitting group(P ＜0．05)．The poordistribution and the leakage of cement were found in 1 and 2 cases respectively in non-splitting group，and found in 5 and 6 cases respectively in splitting group，there were statistical differences between two groups in them(P ＜0．05)．ConclusionsPVP can achieve satisfactory clinical results in the treatment of osteoporotic thoracolumbar vertebral compression fractures with or without vertebral splitting．However，the amount of bone cement infusion may increase，and the poor bone cement diffusion and high incidence of bone cement leakage would appeared in the patients with vertebral splitting，so the managements were performed necessarily with stuffing the vertebral splitting during the operation，avoiding cement spinal leakage，deformity correction lost and re-fracture，and anti-osteoporosis treatment after the operation．
