Introduction to the Posterior Thoracolumbar Fixation System：
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!
