椎体成形术:

当椎体骨折时，通常的长方形骨被压缩和扭曲变形，减低了脊柱的承重稳定性，并压迫神经根甚至脊髓本身，从而导致疼痛。压缩性骨折可能涉及一个或多个脊椎体。 椎体成形术是一种微创手术，用于治疗脊椎锥体压缩性骨折，也就是组成脊柱承重系统的骨质体的骨折。医生在影像导引下向损坏的骨体注入特种水泥混合物，以达到恢复脊椎原形，重建脊柱稳定性的治疗目的。

Vertebroplasty:

When the vertebra is fractured, the bone is compressed, distorted, and deformed. The spine’s stability and capacity of bearing weight are therefore impaired. The nerve roots and the spinal cord can be pressed, which cause pain. Compressed fracture can involve single or multiple vertebras. Vertebroplasty is a minimally invasive procedure. It is designed to treat vertebral compressed fracture. The procedure is performed under radioimage guidance, by a pain specialist, who injects a special concrete-like material into the fractured vertebral body. When hardened, the concrete can help reestablish the shape and strength of the vertebral body and reinstall the stability of vertebral column.
