Some knowledge of Orthopedic Cannulated Screw II

Compression Cannulated Screw
It utilizes deep cutting threads with a large pitch, offering increased resistance to pullout. This feature is of utmost importance, as it ensures the stability of the implant, reducing the risk of complications during the recovery process. Additionally, the large pitch accelerates screw insertion and removal, saving valuable operating time.

Double-Threaded Cannulated Screw
This hollow design enables the screw to be inserted over a guide wire or K-wire, which facilitates accurate placement and reduces the risk of damaging surrounding tissue. Double-threaded cannulated screws are commonly used in procedures involving fracture fixation, especially in areas requiring compression, such as the treatment of certain joint fractures or axial fractures of long bones. They provide stability and compression at the fracture site for optimal bone healing.

In summary, surgery cannulated screws are an important tool in modern orthopedic surgery, helping surgeons perform precise and minimally invasive procedures. Their unique design allows for the use of a guide wire, which improves the accuracy of screw placement and reduces the risk of complications. As technology continues to advance, the application and effectiveness of cannulated screws are likely to expand, further improving patient outcomes in orthopedic care. Whether used for fracture fixation, osteotomy, or joint stabilization, cannulated screws represent a major advancement in surgical technique that contributes to the overall success of orthopedic interventions.
