Vertebral augmentation needles are typically hollow and straight and are available in diamond-shaped, single-bevelled or multi-bevelled stylets. Diamond-tip needles offer optimal ease of penetration into cortical bone, while bevelled needles have superior manoeuvrability. Curved needle systems are also available and possess the ability to navigate up to 90°, allowing access to sites that are difficult to reach using straight needles. Balloon kyphoplasty utilizes an inflatable tamp that may be inserted through the needle cannula. While multiple types of bone cement are available, polymethylmethacrylate (PMMA) remains the most common cement utilized.

术中穿刺针通常是中空和直的，有菱形、单斜面或多斜面穿刺针。菱形针尖最易穿透皮质骨，而斜面针可操作性优越。具有导航角度高达90°曲面针头系统也可使用，允许进入直针难以到达的位置。球囊椎体后凸成形术利用可通过针管插入的充气填塞物。虽骨水泥有多种类型，但PMMA仍然是最常用的。

Curved needle systems are also available and possess the ability to navigate up to 90°具有导航角度高达90°曲面针头系统也可使用？ 什么叫导航角度？弯曲角度？
