Cancellous Screw 6.5mm X 60mm Dia. Full Thread Self Tapping SS316L Orthopedic

The Orthopedic Cancellous Screw with specifications 6.5mm x 60mm, full thread, self-tapping, and SS316L material is an implant used in orthopedic surgeries, particularly for the fixation of fractures in cancellous (spongy) bone. Below is a detailed explanation of its features and uses:

Specifications Breakdown:
6.5mm Diameter: This screw has a diameter of 6.5 millimeters, making it suitable for medium-sized bones, such as those found in the distal radius, femur, tibia, or smaller bones in the hand and foot. The 6.5mm diameter strikes a balance between providing strong fixation in cancellous bone and allowing for appropriate placement in bones of moderate size.

60mm Length: The screw measures 60 millimeters in length, which is ideal for shallow fractures or fractures that do not require deep screw insertion. The length ensures that the screw can provide stable fixation and engage enough cancellous bone for secure anchoring.

Full Thread: The screw is full-threaded, meaning the threads extend along the entire length of the screw. Full threads offer better fixation in cancellous bone by fully engaging with the porous bone structure, ensuring maximum stability. The threads provide greater surface area contact, which enhances the screw’s holding power and reduces the risk of loosening over time.

Self-Tapping: The screw is self-tapping, which means it is designed to cut its own threads into the bone as it is inserted. This feature eliminates the need for pre-drilling, simplifying the surgical process and reducing the time spent on preparation. Self-tapping screws also minimize the risk of damaging surrounding bone tissue and help ensure accurate screw placement.

Cancellous Screw: Cancellous screws are specifically designed for use in cancellous (spongy or trabecular) bone, which is less dense and more porous than cortical bone. These screws are equipped with large, widely spaced threads to provide a secure grip within this type of bone and promote stability in fracture healing.

SS316L (Stainless Steel 316L): The screw is made from SS316L stainless steel, a high-quality, medical-grade alloy that is widely used in orthopedic implants. The “L” in SS316L stands for low carbon, which enhances the material’s corrosion resistance, ensuring the screw remains stable and intact over time. SS316L is also biocompatible, meaning it is well-tolerated by the human body and minimizes the risk of allergic reactions or infections.

Typical Uses:
This screw is commonly used in:

Fracture Fixation: Especially for fractures in cancellous bone, such as those in the femur, tibia, distal radius, or other areas where cancellous bone is present. It helps stabilize fractures and supports bone healing by providing firm fixation.
Osteotomies: In surgeries where bones are intentionally cut and realigned to correct deformities or improve joint function.
Spinal Fixation: In spinal surgeries, particularly in areas of the spine that involve cancellous bone (e.g., vertebral bodies), the screw stabilizes the bone during fusion or other corrective procedures.
Advantages of Full Thread, Self-Tapping Cancellous Screws:
Minimally Invasive: The self-tapping design eliminates the need for pre-drilling, reducing the time and complexity of the surgery. This also minimizes soft tissue trauma and accelerates the healing process.
Strong Fixation: Full-threaded screws provide maximum engagement with cancellous bone, offering superior holding power compared to partially threaded screws. This ensures stable fixation, especially in spongy or trabecular bone.
Easy Insertion: The self-tapping design simplifies insertion by allowing the screw to cut its own threads as it advances into the bone. This reduces the risk of damaging surrounding tissues and bone structures during placement.
Corrosion Resistance: SS316L stainless steel is resistant to corrosion, making it ideal for long-term implantation. It ensures the screw remains intact and functional over time, even in the body’s challenging biological environment.
Biocompatibility: The material is highly biocompatible, reducing the risk of adverse reactions and improving the safety of the implant. The screw integrates well with the bone, facilitating healing and promoting bone fusion.
Conclusion:
The 6.5mm x 60mm Full-Threaded, Self-Tapping Orthopedic Cancellous Screw made from SS316L stainless steel is an excellent choice for stabilizing fractures in cancellous bone. The 6.5mm diameter and 60mm length are ideal for fractures in medium-sized bones, offering strong and stable fixation. The full-thread design ensures optimal engagement with the bone, and the self-tapping feature simplifies the surgical process by eliminating the need for pre-drilling. The use of SS316L stainless steel ensures corrosion resistance and biocompatibility, making it a durable and reliable choice for long-term implantation. This screw is ideal for fracture fixation, osteotomies, and spinal procedures involving cancellous bone.
