2.7 MM LOCKING HEAD SCREW ( STAR HEAD)
The 2.7 MM locking head screw with a star head is a specialized orthopedic implant designed for use in surgeries where secure fixation is essential. Here are its specifications and common uses:
Specification
- Diameter: Typically, the screw 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. Additionally, it has a locking mechanism that allows it to lock securely into a corresponding plate or fixation device.
- Thread Pitch: The screw may have a fine thread pitch, optimized for engaging cortical bone and providing secure fixation. The thread design may also be self-tapping to facilitate insertion.
- Material: The screw is commonly 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: Locking head screws with star heads are commonly used for the fixation of fractures, particularly in osteoporotic bone or situations where traditional screws may not provide adequate stability.
- 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: Locking head screws with star heads are used to secure locking plates or other implants to bone during orthopedic surgeries. The locking mechanism provides additional stability and reduces the risk of screw loosening or backout.
- Complex Fractures: They are particularly useful in cases of complex fractures or in bones with poor bone quality, where traditional fixation methods may be inadequate.
Overall, the 2.7 MM locking head screw with a star head is a valuable orthopedic implant utilized in various surgical procedures to provide stable fixation, particularly in challenging clinical scenarios where secure fixation is crucial for successful outcomes.
