Cancellous Screw 6.5mm X 65mm Dia. Full Thread Self Tapping SS316L Orthopedic

The Orthopedic Cancellous Screw with specifications 6.5mm x 65mm, full thread, self-tapping, and SS316L material is a specialized implant used for securing fractures in cancellous (spongy) bone. Here’s a detailed breakdown of its features and advantages:

Specifications Breakdown:
6.5mm Diameter: The screw has a diameter of 6.5mm, which is appropriate for medium-sized bones, such as those in the distal radius, femur, tibia, or other medium to large bones. The diameter provides enough surface area to securely anchor the screw in cancellous bone, which is softer and more porous compared to cortical bone.

65mm Length: The screw is 65mm long, making it suitable for fractures that require moderate screw penetration. The length is often chosen based on the location of the fracture and the thickness of the bone. A screw of this length is typically used for fractures in areas with shallow bone depth, providing the necessary stability without over-penetrating the bone.

Full Thread: The screw is full-threaded, meaning the threads extend along the entire length of the screw. Full-threaded screws provide enhanced stability in cancellous bone by ensuring that the threads engage with the bone across the full length of the screw, improving grip and reducing the likelihood of screw loosening over time.

Self-Tapping: The screw is self-tapping, meaning it is designed to cut its own threads as it is inserted. This feature eliminates the need for pre-drilling a hole, simplifying the surgical process. The self-tapping nature of the screw helps reduce surgical time, minimizes trauma to surrounding tissues, and ensures accurate placement by allowing the screw to follow its path into the bone.

Cancellous Screw: The screw is designed specifically for use in cancellous (spongy or trabecular) bone, which is softer and more porous than cortical bone. Cancellous screws typically have larger, more widely spaced threads to provide secure fixation in the softer, less dense bone tissue. These screws are ideal for fractures in areas where cancellous bone is present, such as the distal femur, proximal tibia, and other bones with significant trabecular structure.

SS316L (Stainless Steel 316L): The screw is made from SS316L stainless steel, a medical-grade material that is highly corrosion-resistant, strong, and biocompatible. The “L” in SS316L indicates low carbon, which improves the material’s resistance to corrosion and enhances its overall longevity in the body. SS316L is a popular choice for medical implants due to its strength, durability, and ability to withstand the physiological environment inside the human body.

Typical Uses:
The 6.5mm x 65mm Full-Threaded, Self-Tapping Cancellous Screw is commonly used for:

Fracture Fixation: In cancellous bone areas such as the femur, tibia, distal radius, and other bones with a spongy structure. The screw provides stability to the fractured bone, allowing it to heal properly by keeping the bone fragments in place.
Osteotomies: In procedures where bones are intentionally cut and realigned to correct deformities or realign joints.
Spinal Fixation: For stabilization of the vertebral body during spinal surgeries, particularly when dealing with cancellous bone in the vertebral bodies.
Advantages of Full Thread, Self-Tapping Cancellous Screws:
Minimally Invasive: Self-tapping screws eliminate the need for pre-drilling, making the procedure quicker and less invasive. This reduces the risk of damaging surrounding tissues and promotes faster recovery.
Strong and Secure Fixation: Full-threaded screws provide superior engagement with the cancellous bone, ensuring a strong, stable fixation. The threads maximize the surface area of contact with the bone, which is important for preventing screw loosening and enhancing long-term fixation.
Improved Surgical Efficiency: The self-tapping feature allows for easier insertion, as the screw cuts its own thread into the bone. This simplifies the surgical process and reduces time spent on preparation, making the procedure more efficient.
Corrosion Resistance: SS316L stainless steel is highly resistant to corrosion, ensuring the screw maintains its integrity and performance over time, even when exposed to the harsh biological environment within the body.
Biocompatibility: SS316L is known for its excellent biocompatibility, reducing the risk of adverse reactions and making the screw a safe and effective choice for long-term use in the human body.
Conclusion:
The 6.5mm x 65mm Full-Threaded, Self-Tapping Orthopedic Cancellous Screw made from SS316L stainless steel is an excellent choice for securing fractures in cancellous bone. The 6.5mm diameter and 65mm length make it ideal for medium-sized fractures, offering reliable and strong fixation in cancellous bone. The full-thread design ensures maximum engagement with the bone, providing superior stability. The self-tapping feature simplifies the surgical procedure by eliminating the need for pre-drilling, while SS316L stainless steel ensures the screw’s durability, corrosion resistance, and biocompatibility. This screw is well-suited for fracture fixation, osteotomies, and spinal fixation in areas with cancellous bone.
