Posterior Cervical Screw System

What is Posterior Cervical Screw System？

Posterior Cervical Screw System is a medical device used in spinal surgeries to stabilize the cervical spine (neck region) by fixation of the spinal column with screws and rods.

The system consists of pedicle screws, lateral mass screws, hooks, and rods that are used to form a construct to stabilize the spine.

The posterior cervical screw system is used to treat various spinal conditions such as degenerative disc disease, spinal stenosis, herniated discs, and spinal fractures.

The system is typically used in posterior cervical fusion surgeries.

What is the material of Posterior Cervical Screw System？

Posterior cervical screw systems can be made of various materials, including titanium, stainless steel, and cobalt-chromium. The choice of material may depend on factors such as strength, biocompatibility, and imaging compatibility.

What are the types of Posterior Cervical Screw System?

Posterior cervical screw systems are classified based on various factors such as the size of the screws, design of the screws, the type of the rod, and the system’s intended use. Here are some common types of posterior cervical screw systems:

1. Polyaxial Screws: These screws have a ball-and-socket joint design that allows for flexibility in screw placement and rod attachment.

2. Monoaxial Screws: These screws have a fixed-angle design and can be used in situations where the screw needs to be placed at a specific angle.

3. Cannulated Screws: These screws have a hollow center that allows for the insertion of a guide wire to help with screw placement.

4. Variable-Angle Screws: These screws have a unique design that allows for the screw angle to be adjusted during insertion.

5. Occipital-Cervical (OC) Screws: These screws are used in the occipital-cervical region of the spine, which is located at the base of the skull.

6. Thoracic Pedicle Screws: These screws are used in the thoracic spine, which is located in the middle portion of the spine.

7. Lumbar Pedicle Screws: These screws are used in the lumbar spine, which is located in the lower portion of the spine.

The specific type of posterior cervical screw system used depends on the patient's individual needs and the surgeon's preference.
