Cardinal公司生产的脊柱骨骼粘合剂获得FDA批准

一种新型骨骼粘合剂被设计给医生用于固定脊椎骨折。这种粘合剂已经获得了美国食品药品管理局的批准。

这种粘合剂通常用于脊柱外科手术。在手术中，医生在影象学检查的引导之下，从后背向发生骨折的脊柱插入一根很长的针，通过这根针注射骨骼粘合剂。骨骼内粘合剂变硬从而填充骨折导致的缝隙，加强被破坏的脊椎，减轻患者的疼痛以及所承受的压力。

这种新型Ava-Tex不透辐射的骨骼粘合剂是由一种叫做聚甲基丙烯酸甲酯(PMMA)的丙烯酸(类)树脂制作而成的。这种骨骼粘合剂在混合之后，给医生提供的注射时间较长，设计可以用于荧光成像扫描检查。这种新型骨骼粘合剂是Cardinal公司的产品，并且获得了CE标志。

“医生一直需要一种设计用于治疗脊椎骨折的黏合剂，既然我们已经获得FDA的批准，我们十分高兴能够提供这种产品。”Cardinal公司的副总裁、特殊手术部总经理Tom Daulton如此评论说。Ava-Tex的注射时间得到了延长，这就为在手术中安全注射这种骨骼黏合剂提供了充足的时间。

Bone Cement for Vertebroplasty
 
A new bone cement is designed for use by doctors to fix fractures of the spine. The cement has been cleared by the U.S. Food and Drug Administration (FDA).

The cement is commonly used in vertebroplasty. In this procedure, doctors guided by imaging insert a long needle through the back into a fractured vertebra, injecting the bone cement through the needle. The cement hardens inside the bones and fills gaps created by the fracture, strengthening collapsed vertebrae and relieving pain and pressure for the patient.

The new Ava-Tex radiopaque bone cement is made from an acrylic resin called polymethylmethacrylate (PMMA). The cement offers doctors an extended injection time once the cement is mixed and is designed for visibility with fluoroscoping imaging. The new bone cement is the product of Cardinal Health (McGaw Park, IL, USA) and has received the CE Mark.

“Physicians have been asking for a cement designed to treat vertebral fractures, and we are very pleased to be able to offer this product, now that we have FDA clearance,” noted Tom Daulton, vice president and general manager of special procedures at Cardinal Health. Ava-Tex has an extended injection time, which gives doctors the extra time needed during the procedure to safely inject the cement.
