To study the distribution of bone cement in unilateral puncture percutaneous vertebroplasty (PVP). @@@ A total of 64 patients with osteoporotic vertebral compression fractures (OVCF) who underwent unilateral PVP were included in this study. The vertebral body was longitudinally divided into four equal parts. The intermediate layer between each part was representative of the part and there were four layers in total. Each layer was divided into 4 regions a, b, c, and d by the crossed lines at the center of the vertebral body. Region c was the first half of the puncture side and region d was the second half of the puncture side. Region a was the first half of the opposite side, and b was the second half of the opposite side. Bone cement filling areas in the four layers and the four regions of each layer were compared. @@@ There were significant differences in visual analogue scale (VAS) scores before and after surgery (PaEuro<overline>< 0.05). Variance analysis indicated that the bone cement filling ratio of the region b in each layer was significantly lower than the other three regions, and that the bone cement filling ratio of region a was equal to that of the region d. @@@ Unilateral puncture PVP can reduce VAS scores, and plays a role in reducing pain. The bone cement showed a regular distribution.
