Percutaneous balloon kyphoplasty aims to restore vertebral height, correct angular deformity and stabilize the spine in the setting of vertebral compression fractures. The patient is positioned prone with supports under the iliac crests and upper thorax to allow gravity to extend the spine. In the treatment of lumbar fractures, we evaluated patient positioning with the contribution of hip extension to increase anterior ligamentotaxis, thus facilitating restoration of vertebral height. Our positioning technique created a mean anterior height increase from 72% to 78% of the average height of the cranial and caudal vertebrae (p=0.037). Balloon inflation did not significantly further increase anterior or posterior vertebral height, or Cobb angle.
经皮球囊椎体后凸成形术旨在恢复椎体高度、矫正角畸形和稳定脊柱骨折。患者取俯卧位，髂嵴和上胸部下方有支撑物，以利用重力延长脊柱。在治疗腰椎骨折时，我们评估了患者的体位，利用髋关节伸展来增加前韧带轴，从而促进椎体高度的恢复。我们的定位技术使平均前高度增加了 72%至 78%，达到颅尾椎体平均高度（p=0.037）。球囊充气并没有显著增加椎体的前后高度或 Cobb 角。
