What is a cannulated screw?
A cannulated screw is a special type of orthopedic screw used to fix bone fragments during various surgical procedures. Its unique construction features a hollow core or cannula into which a guide wire can be inserted. This design not only increases the precision of placement, but also minimizes trauma to surrounding tissue during surgery.

Application in orthopedic surgery
Surgical cannulated screw are commonly used in a variety of orthopedic procedures, including:
Fracture Fixation: They are commonly used to fix fractures, especially those of the hip, ankle, and wrist. The ability to insert the screws over a guide wire allows for precise alignment of the fractured bone segments.
Osteotomy: During the process of cutting and repositioning the bone, cannulated screws may be used to secure the new position and promote proper healing and function.
Joint Stabilization: Cannulated screws are also used to stabilize joints, especially in cases of ligament reconstruction or repair.
Screw Retention Mechanism: In some cases, these screws are used with other fixation devices to enhance the stability of the joint and improve the overall outcome.
These fixation devices are specially designed to secure small bones, bone fragments, and osteotomies in place. They provide stability during the healing process and promote proper alignment. However, it is crucial to note that they are not suitable for use in interfering with soft tissues or fixation in soft tissue. It’s important to follow the intended use and recommendations provided by medical professionals for optimal and safe outcomes.
