2.7 MM CORTICAL SCREW ( STAR HEAD)
The 2.7 MM cortical screw with a star head is a specific type of orthopedic screw used in various surgical procedures, particularly in orthopedic and trauma surgeries. Here are its specifications and common uses:
Specification
- Diameter: The screw typically has a diameter of 2.7 millimeters, allowing for precise placement in cortical bone.
- Head Design: The screw features a star-shaped head, which provides improved grip and torque during insertion compared to traditional screw heads.
- Thread Pitch: The screw has a fine thread pitch, optimized for engaging cortical bone and providing secure fixation.
- Material: Usually made from stainless steel or titanium alloy, offering strength, corrosion resistance, and biocompatibility.
- Length: Available in various lengths to accommodate different surgical needs and bone anatomy.
Uses
- Fracture Fixation: Cortical screws with star heads are commonly used for the fixation of fractures in cortical bone, such as those in long bones like the femur, tibia, humerus, or radius.
- Osteotomies: They are employed in corrective osteotomies to realign bones that have healed in an incorrect position or to address deformities such as malunions or nonunions.
- Arthrodesis: Used in fusion procedures, such as joint arthrodesis, to promote bone fusion and stability. Examples include ankle fusion, subtalar fusion, or fusion of small joints in the hand or foot.
- Hardware Fixation: Cortical screws with star heads are also used to secure plates, rods, or other implants to bone during orthopedic surgeries, providing additional stability and fixation.
- Sports Injuries: They are commonly employed in the treatment of sports-related injuries, such as stress fractures or avulsion fractures, where secure fixation is essential for optimal healing and recovery.
Overall, the 2.7 MM cortical screw with a star head is a versatile orthopedic implant utilized in a wide range of surgical procedures to provide stable fixation of fractures, correction of deformities, promotion of bone fusion, and reinforcement of orthopedic hardware. Its unique head design enhances grip and torque during insertion, contributing to successful surgical outcomes.
