Introduction to Cervical Fixation System:

Degenerative disease is the most common spinal surgery disease in clinic, which seriously affects the life and work of patients. Once the drug and physical conservative treatment is ineffective, surgical treatment is often the final choice. The surgical method has developed from simple discectomy to the most common interbody fusion at present, and a series of fusion methods appear in the pursuit of perfect interbody fusion, while the fusion cage made of PEEK (poly-ether-ether-ketone) is currently one of the common surgical materials. It can transmit X-ray, so in MRI scanning (it can be seen that two tantalum metal markers are placed at the front and rear ends of the fusion cage), its elastic modulus is closer to bone, and its stress shielding effect is small, which has a positive significance for promoting bone fusion. Composite interbody fusion cage is the safest and most widely used cage in clinical application, which has obvious advantages.

The human vertebral body is the hub of human trunk activities, and all physical activities are all increasing the burden of lumbar vertebrae. With the growth of age, excessive activities and overload accelerate the aging of lumbar vertebrae, and secondary pathological changes may happen under the effect of external force, resulting in rupture of intervertebral disc annulus fibrosus, protrusion of nucleus pulposus in intervertebral disc, causing lumbocrural pain and neurological dysfunction. Lumbar degeneration is mainly a physiological process that changes with age, however, many factors can accelerate the process of lumbar aging degeneration and cause a series of diseases and symptoms. Libeier’s spinal internal fixator has a good effect on these diseases and symptoms.

Libeier began to produce spinal screws in 2002, and has accumulated product design experience for many years. The products are more in line with clinical needs, so are the durability and compatibility after implantation. Libeier’s products have been sold at home and abroad for many years, and the new design concept has been widely recognized by the clinical users!
