Herbert Screw 4.5 mm (Headless Compression Screw)

Fracture Fixation:The 4.5 mm Headless Compression Screw is commonly used for the fixation of fractures, particularly in small bones and joints such as the hand, wrist, foot, and ankle. It provides stable internal fixation and allows for compression across the fracture site, aiding in the healing process.
Osteotomies:The 4.5 mm Herbert screw is often employed in osteotomy procedures, which involve cutting and reshaping bones. It helps secure bone fragments in the desired alignment, allowing for proper healing and fusion.
Bone Graft Fixation: When bone grafts are used to assist in bone healing or fusion, 4.5 mm Headless Screw can be employed to secure the grafts in place, ensuring their stability and promoting graft integration.

Nonunion Treatment: The 4.5 mm Herbert screw may be used in the treatment of nonunion fractures, where bone healing has not occurred naturally. It can help facilitate bone union by providing compression and stability at the nonunion site.
Corrective Procedures: In certain cases, the 4.5 mm Herbert Screw is utilized in corrective procedures to address deformities or misalignments of bones, such as in the correction of angular deformities or malunions.
Arthrodesis: Arthrodesis refers to the fusion of two or more adjacent bones to eliminate joint motion. The 4.5 mm Herbert Screw can be utilized in arthrodesis procedures to provide compression and stability at the fusion site.

Sports Medicine:The 4.5 mm Headless Compression Screw is occasionally used in sports medicine procedures, particularly in the treatment of fractures or ligament injuries in athletes. Its small size and compression capabilities make it suitable for certain sports-related injuries.

Headless Design: The 4.5 mm Herbert screw has a unique design without a traditional screw head. Instead, it features a cylindrical body with threads along its entire length.
Compression Function: The 4.5 mm Headless Screw is designed to provide compression across a fracture or fusion site. It is commonly used in applications where compression forces are required for optimal bone healing.
Cannulated Structure: Many 4.5 mm Headless Compression Screws have a hollow, cannulated structure. This allows for precise placement over a guide wire during surgery and facilitates proper alignment.

Self-Tapping Threads: The 4.5 mm Herbert screw typically has self-tapping threads, allowing it to be inserted directly into bone without the need for pre-drilling.
Biocompatible Material: The 4.5 mm Headless Compression Screw is typically made from a biocompatible material such as stainless steel or titanium alloy, which is well-tolerated by the body and minimizes the risk of adverse reactions.
Variable Length Options: The 4.5 mm Headless Screw are available in various lengths to accommodate different anatomical requirements and surgical procedures.

Instrumentation: The 4.5 mm Headless Compression Screw may come with specialized instrumentation, including screwdrivers, guide wires, and drill bits, to facilitate precise placement and implantation during surgery.
Radiolucent Properties: Some versions of the 4.5 mm Herbert screw may have radiolucent properties, enabling better visibility of the bone during postoperative imaging procedures like X-rays or CT scans.
