To investigate the effect of bone cement on the vertebral body and biomechanical properties in percutaneous cement discoplasty (PCD) for degenerative lumbar disc disease.
Three-dimensional reconstruction of L2 ~ L3 vertebral bodies was performed in a healthy volunteer, and the corresponding finite element model of the spine was established. Biomechanical analysis was performed on the changes in stress distribution in different groups of models by applying quantitative loads.
Models with percutaneous discoplasty (PCD) showed improved stability under various stress conditions, and intervertebral foraminal heights were superior to models without discoplasty.
Cement discoplasty can improve the stability of the vertebral body to a certain extent and restore a certain height of the intervertebral foramen, which has a good development prospect and potential.
探讨经皮骨水泥椎间盘成形术（PCD）治疗退变性腰椎间盘疾病时骨水泥对椎体及生物力学性能的影响。
对健康志愿者的 L2~L3 椎体进行三维重建，并建立相应的脊柱有限元模型。通过施加定量载荷，对不同组模型的应力分布变化进行生物力学分析。
PCD 模型在各种应力条件下表现出更好的稳定性，椎间孔高度优于无椎间盘成形术模型。
骨水泥椎间盘成形术可在一定程度上提高椎体稳定性，恢复一定的椎间孔高度，具有良好的发展前景和潜力。
