Understanding of Spine Pedicle Screw

Why do we use pedicle screw for spinal fractures?
The lumbar spine, as the bottom structure of the human spine, which is the primary weight-bearing unit of the trunk, supporting the entire weight of the upper body. However, the lumbar spine can become “unstable” due to various etiologies. Examples include lumbar fractures, spondylolysis or degenerative lumbar spondylolisthesis, degenerative lumbar scoliosis, lumbar disc herniation with vertebral endplate inflammation, open-mouth-like osteophytes on the anterior and posterior edges of vertebrae, severe hypertrophy of the posterior articular processes, and iatrogenic bone destruction. In these cases, the vertebral sequence of the lumbar spine may become disordered or even rotated and displaced, leading to impaired stability and subsequent low back pain in patients. Therefore, when the lumbar spine presents with the aforementioned “unstable” conditions and conservative treatment fails, “screw fixation” is required to maintain and enhance lumbar stability.

What are the characters our Spine Pedicle Screw System?
Our spine pedicle screw products are available in six different diameter specifications, including φ4.5mm, φ5.0mm, φ5.5mm, φ6.0mm, φ6.5mm, and φ7.0mm.

The design of dual thread for cortical and cancellous bone respectively, enhances the screw purchase, suitable to wider bone quality conditions of patients. Self-tapping screw tip makes the inserting easier.

Breakable set screw prevents thread damage due to overexertion.
Reverse angle thread effectively prevents screw retreating.
Design of blunt-pointed thread starting prevents cross threading.
Screw

Buckle Type Crosslink, 35 ° range of motion for easy and flexible operation.

What are the main components of a spinal pedicle system?
An internal spinal fixation system consists of a screw, a set screw, connection rod, and crosslink. The pedicle is a bony structure located at the posterior part of the spinal vertebral body, which has high strength and stability. By implanting the pedicle screw into the pedicle, the bone strength of the pedicle is utilized to provide stable fixation, creating favorable conditions for the healing and recovery of the spine.
