Polyaxial Pedicle Screw 5.5mm X 45mm With Inner Nut Single Thread Orthopedic Spine Surgical Titanium

The “Polyaxial Pedicle Screw 5.5mm X 45mm With Inner Nut Single Thread Orthopedic Spine Surgical Titanium” is a specific type of orthopedic implant commonly used in spine surgery. Here’s a breakdown of its components:

Polyaxial Pedicle Screw: This indicates that the screw is polyaxial, meaning it can move in multiple directions after being implanted in the pedicle of a vertebra. Polyaxial screws provide flexibility in positioning and alignment during surgery.
5.5mm X 45mm: These measurements specify the dimensions of the screw:
5.5mm: This is the diameter of the screw shaft. The diameter affects the strength and stability of the screw.
45mm: This is the length of the screw. The length may vary based on the specific surgical procedure and patient anatomy.
With Inner Nut: This indicates that the screw comes with an inner nut. The nut is used to secure the screw in place after it has been inserted into the pedicle.
Single Thread: This specifies the type of threading on the screw. A single thread means the screw has a continuous helical ridge along its shaft, allowing it to be securely anchored into the bone.
Orthopedic Spine Surgical Titanium: This describes the material composition of the screw. Titanium is commonly used in orthopedic implants due to its biocompatibility, strength, and resistance to corrosion. Titanium implants are well-suited for use in spine surgery.
In summary, the “Polyaxial Pedicle Screw 5.5mm X 45mm With Inner Nut Single Thread Orthopedic Spine Surgical Titanium” is a specialized orthopedic screw used in spine surgery. It has a 5.5mm diameter, 45mm length, is made of titanium, features a polyaxial design for flexibility, includes an inner nut for fixation, and has a single-threaded shaft for anchoring into the bone.
