About 3.5mm cortex screw (20 TPI)

The 3.5mm Cortex Screw with 20 threads per inch (TPI) is ideal for securing small bone fractures, offering excellent thread engagement for stable fixation. Its 20 TPI design enhances grip in cortical bone, reducing the risk of loosening during healing. Advin Health Care manufactures these screws with rigorous quality standards, ensuring biocompatibility and surgical reliability. This screw is a versatile tool for orthopedic surgeons, supporting efficient fracture management and improved patient recovery outcomes.

Advanced Features:

3.5mm diameter suitable for small bone fracture fixation
20 TPI for superior thread engagement and compression
High-quality stainless steel construction for strength and corrosion resistance
Provides reliable stabilization in trauma orthopedic surgeries

Engineered for Reliable Fracture Fixation

The 3.5mm cortex screws precise threading and low-profile design ensure stable fixation of bone fragments in both small and complex fractures. Whether composed of stainless steel or titanium, these screws are meticulously crafted for optimal biocompatibility and rigidity, making them a trusted choice for orthopedic professionals.

Versatile Application and Customization

Available in several lengths (1050 mm), with selectable drive types and head configurations, these screws accommodate a range of surgical needs. Their high dimensional accuracy and individually sterile packaging allow for flexible integration into different fracture management protocols.

Quality and Safety Compliance

ISO 13485 certification and CE marking guarantee adherence to international standards for safety and quality, while corrosion resistance and sterile packaging maintain implant integrity. With a recommended shelf life of five years when properly stored, reliability is ensured from manufacturing to operating room.

FAQs of 3.5mm cortex screw (20 TPI):

Q: How should the 3.5mm cortex screw be stored prior to use?

A: These screws must be stored in dry, sterile conditions to maintain their sterility and preserve their five-year shelf life. Ensure original packaging remains intact until the point of surgery.

Q: What is the primary surgical application of the 3.5mm cortex screw?

A: The screw is primarily used for rigid fixation of small bone fragments, particularly in metaphyseal or diaphyseal regions during fracture treatment in orthopedic surgery.

Q: When is it appropriate to select this cortex screw over other implant types?

A: This cortex screw is ideal for cases requiring precise yet stable fixation in small bones or in areas with thin cortical layers, as its fine thread (20 TPI) offers excellent purchase and reduces the risk of bone splitting.

Q: Where can these screws be effectively utilized in the body?

A: They are most frequently used in small bones or regions requiring low-profile fixation, such as in hand, wrist, ankle, or similar anatomical sites prone to small or comminuted fractures.

Q: What is the process for inserting this screw during surgery?

A: After appropriate pre-drilling and, if needed, tapping, the self-tapping screw is manually driven into the bone using a compatible hexagonal or cross head tool. The process allows for secure, controlled implantation without powered instruments.

Q: What are the main benefits of using a 3.5mm cortex screw for fracture fixation?

A: These screws provide strong, biocompatible fixation with high dimensional accuracy, corrosion resistance, and flexibility in length and drive type, contributing to safer surgical outcomes and enhanced healing conditions.

Q: Is this product compliant with international standards?

A: Yes, the 3.5mm cortex screw is ISO 13485 certified and CE marked, ensuring compliance with rigorous international safety and performance standards for medical devices.
