Cannulated Cancellous Screw 7.0mm X 60mm Dia. 16mm Thread SS316L Orthopedic

The Orthopedic Cannulated Cancellous Screw with the specifications 7.0mm x 60mm, 16mm thread, and SS316L material is designed for orthopedic surgeries, particularly for the fixation of fractures in cancellous (spongy) bone. Here’s a detailed breakdown of its features:

Specifications Breakdown:
7.0mm Diameter: The screw has a diameter of 7.0 millimeters, which is on the larger side for orthopedic screws. This size provides a strong and stable fixation in larger or denser bones, such as the femur or tibia, and is suitable for use in situations where high stability is required.

60mm Length: The screw measures 60 millimeters in length. The length of the screw is chosen based on the fracture site, bone size, and the specific surgical requirements. This length is typically suitable for fractures that require a deeper insertion into the bone or are located in areas with more compact bone structures.

16mm Thread: The threaded portion of the screw is 16 millimeters long. The length and design of the threads are tailored to engage effectively with cancellous bone, providing secure fixation by embedding into the softer, spongy bone tissue.

Cannulated: The screw is cannulated, meaning it has a hollow center. This allows for the use of a guidewire during placement, ensuring the screw is inserted with precision. The cannulated design is particularly advantageous in minimally invasive surgeries, reducing trauma to surrounding tissues and improving the overall efficiency of the procedure.

Cancellous Screw: Cancellous screws are designed specifically for use in cancellous bone (spongy or trabecular bone). This type of bone is less dense and more porous than cortical bone, so cancellous screws typically have larger, more spaced-out threads to provide a better grip in the softer, more porous bone structure.

SS316L (Stainless Steel 316L): The screw is made from 316L stainless steel, a high-quality medical-grade alloy. The “L” stands for “low carbon,” which gives it better resistance to corrosion, reducing the risk of adverse reactions or infections when the screw is implanted in the body. SS316L is known for its strength, durability, and biocompatibility, making it ideal for use in orthopedic implants.

Typical Uses:
This screw is primarily used for:

Fracture Fixation: In cases of fractures in cancellous bone, such as those in the femur, tibia, pelvis, or other bones with spongy bone tissue. It helps stabilize the bone during the healing process.
Osteotomies: In surgeries where bone is cut and realigned, such as joint realignment procedures or correction of deformities.
Spinal Fixation: In spinal surgeries, particularly for stabilizing vertebrae, where cancellous bone is involved.
Advantages of Cannulated Stainless Steel Screws:
Minimally Invasive: The cannulated design allows for more precise placement over a guidewire, minimizing the need for large incisions. This reduces trauma to the surrounding soft tissues and speeds up recovery.
Strength and Durability: SS316L stainless steel is a durable and corrosion-resistant material, ensuring that the screw maintains its integrity over time. This is especially important for long-term use in the body.
Biocompatibility: Stainless steel 316L is highly biocompatible, reducing the risk of allergic reactions or tissue rejection. It is ideal for implants that need to be integrated with bone tissue over an extended period.
Conclusion:
The 7.0mm x 60mm Cannulated Cancellous Screw made from SS316L stainless steel is an effective and reliable solution for fixing fractures in cancellous bone. The screw’s large diameter (7.0mm) and 16mm threaded portion offer strong fixation in softer, spongy bone, while the 60mm length allows for deeper insertion. The cannulated design aids in precise placement with minimal invasiveness. SS316L stainless steel provides the screw with strength, corrosion resistance, and biocompatibility, ensuring it remains durable and integrates well with bone tissue. This screw is an excellent choice for a variety of orthopedic procedures, particularly those involving fracture stabilization or bone realignment.
