Canwell Medical Spine Implants Titanium Pedicle Screw Probe For Lumbar Spinal Set

Dyna International’s Orthopedic spinal pedicle screws are crucial components in spinal fusion surgeries, a common procedure for treating various spinal conditions such as degenerative disc disease, spinal instability, and deformities. These screws are designed to stabilize the spine by being implanted into the pedicles, which are small bony projections from the vertebral bodies.

Here is a detailed description of orthopedic spinal pedicle screws:

1. Material Composition: Orthopedic spinal pedicle screws are typically made from high-quality materials like titanium or stainless steel. These materials offer excellent strength, corrosion resistance, and biocompatibility, ensuring long-term stability within the body.

2. Design and Structure: The screws have a threaded cylindrical design with a pointed tip for ease of insertion. The threads on the screw enhance its grip within the pedicle, providing stability for spinal fusion. Some pedicle screws may feature a dual-thread design or variable pitch to optimize purchase in the bone.

3. Cannulated Design: Many orthopedic pedicle screws are cannulated, meaning they have a hollow core. This design allows for the insertion of a guide wire to assist in precise screw placement during surgery. It also facilitates the injection of bone graft material into the surrounding area to promote fusion.

4. Diameter and Length Variations: Pedicle screws come in various diameters and lengths to accommodate the anatomical variations among patients. Surgeons carefully select the appropriate size to ensure a secure fit and proper spinal stabilization.

5. Screw Head Options: The screws may have different head configurations, such as a hexagonal or torx design, to accommodate specific instrumentation for insertion. Some screws also have a set screw mechanism that locks the rod into place.

6. Dual-Lead Threads: Some advanced pedicle screws have dual-lead threads, meaning the threads have two different pitches. This design aims to enhance the speed and stability of screw insertion, reducing surgical time and potential complications.

7. Radiopacity: To aid in postoperative imaging, these screws are often made radiopaque, allowing clear visibility on X-rays and other imaging modalities. This feature helps surgeons assess the placement accuracy and monitor the fusion process.

8. Anti-backout Features: Many pedicle screws incorporate anti-backout mechanisms, such as set screws or locking caps, to prevent unintended loosening after implantation.

Orthopedic spinal pedicle screws play a vital role in providing structural support during the healing process after spinal fusion surgery. Their design and materials are carefully selected to ensure biomechanical stability, fusion success, and long-term patient outcomes.
