Cannulated screws are a type of orthopedic implant used to fix bone fractures. They are called “cannulated” because they have a hollow center that allows a guide wire to be inserted through the center of the screw and into the bone. This guide wire helps the surgeon place the screw in the correct position for optimal healing.
Cannulated screws are typically made of titanium or stainless steel and come in a variety of sizes and shapes to fit different bone types and fracture patterns. They are commonly used in the treatment of fractures of the ankle, wrist, and hip, as well as in certain spinal surgeries.
