headless cannulated screw
A headless cannulated screw represents a significant advancement in orthopedic fixation technology, designed to provide superior compression and stability in bone fracture treatment. This innovative medical device features a unique design without a traditional head, allowing it to be completely embedded within the bone surface for optimal aesthetic and functional results. The cannulated structure consists of a hollow core running through the length of the screw, enabling precise placement over a guide wire during surgical procedures. These screws are manufactured from high-grade medical titanium or stainless steel, ensuring biocompatibility and durability. The threaded design typically includes differential pitching, with wider threads at the tip and narrower threads near the top, creating optimal compression when tightened. This configuration allows surgeons to achieve stable fixation while minimizing soft tissue irritation. The screws come in various diameters and lengths to accommodate different anatomical requirements and fracture patterns. Their application spans across multiple orthopedic procedures, including small bone fixation, arthrodesis, osteotomy fixation, and fracture repair in both weight-bearing and non-weight-bearing areas. The headless design particularly excels in procedures where hardware prominence could cause complications or patient discomfort.
