To compare the incidence of fracture between sandwich vertebra and ordinary adjacent vertebra after percutaneous kyphoplasty (PKP).
We analyzed 225 consecutive patients with osteoporotic vertebral compression fractures who underwent PKP between January 2016 and December 2020 at our medical institution. The sandwich vertebrae was located between 2 cement-augmented vertebra and was followed for at least 12 months. The clinical data of patients with sandwich vertebra and ordinary adjacent vertebra were recorded, and the incidence of postoperative fracture between sandwich vertebra and ordinary adjacent vertebra was compared.
The mean continuous follow-up time was 31.30 ± 18.04 months in patients with sandwich vertebra and 25.85 ± 7.96 months in patients with ordinary adjacent vertebra. It should be noted that the incidence of sandwich vertebral fractures was 10.00%, which was not statistically higher than 3.26% for ordinary adjacent vertebral fractures. However, a significant difference was observed in the cement volume of single vertebral body, procedure time, and bleeding.
Although the volume of cement in a single vertebral body is less and the procedure time and bleeding are more, the incidence of sandwich vertebral fracture is not higher than that of ordinary adjacent vertebral body.
比较经皮椎体后凸成形术（PKP）后夹心椎与普通相邻椎骨折的发生率。
我们分析了 2016 年 1 月至 2020 年 12 月在我院接受 PKP 的 225 例连续骨质疏松性椎体压缩骨折患者。夹心椎位于 2 个水泥增强椎之间，随访至少 12 个月。记录夹心椎和普通相邻椎患者的临床资料，比较术后夹心椎和普通相邻椎骨折的发生率。
夹心椎患者的平均连续随访时间为 31.30±18.04 个月，普通相邻椎患者为 25.85±7.96 个月。值得注意的是，夹心椎骨折的发生率为 10.00%，并不高于普通相邻椎骨折的 3.26%。然而，在单椎体水泥量、手术时间和出血方面存在显著差异。
虽然单个椎体的水泥量较少，手术时间和出血较多，但夹心椎骨折的发生率并不高于普通相邻椎骨折。
