Large Cannulated Cancellous Screw 7.0mm X 50mm Dia. 16mm Thread Titanium

The Orthopedic Large Cannulated Cancellous Screw with the specifications 7.0mm x 50mm, 16mm thread, and Titanium material is an implant used primarily in orthopedic surgeries. Here’s a detailed breakdown of its features:

Specifications Breakdown:
7.0mm Diameter: The screw has a diameter of 7.0 millimeters, which is considered large for orthopedic screws. This size ensures it provides secure fixation, especially in larger bones or areas where thicker bone structures are present.

50mm Length: The screw measures 50 millimeters in length from tip to head. The length is selected based on the fracture location and the bone’s specific anatomy. A shorter screw like this is often used in smaller or less deep fractures or when a less invasive procedure is required.

16mm Thread: The threaded portion of the screw is 16 millimeters long. This part of the screw is designed to engage the cancellous bone and provide stable fixation by embedding itself into the porous structure of the bone.

Cannulated: The screw is cannulated, meaning it has a hollow center. This allows for the use of a guidewire during insertion, which helps to accurately position the screw. The cannulated design is particularly useful in minimally invasive surgeries, as it allows the surgeon to place the screw with more precision while reducing trauma to surrounding tissue.

Cancellous Screw: This screw is specifically designed for use in cancellous (spongy or trabecular) bone, which is less dense and more porous than cortical bone. The larger threads of the cancellous screw help to anchor the screw securely into this type of bone, ensuring a stable fixation.

Titanium: The screw is made from titanium, a material renowned for its excellent strength-to-weight ratio, durability, and biocompatibility. Titanium is resistant to corrosion and integrates well with bone, making it ideal for long-term orthopedic implants.

Typical Uses:
This screw would be used in various orthopedic procedures, such as:

Fracture Fixation: Especially in bones like the femur, tibia, or pelvis, where cancellous bone is found. The screw helps stabilize the bone during the healing process.
Osteotomies: For repositioning bones that may be misaligned or deformed.
Spinal Fixation: In spinal surgeries to stabilize vertebrae during healing or to correct deformities.
Advantages of Cannulated Titanium Screws:
Minimally Invasive: The cannulated design allows for precise screw insertion with the help of a guidewire. This reduces the size of the incision needed and results in faster recovery and less tissue damage.
Strength and Stability: The titanium material provides strength, ensuring that the screw will hold up under stress while being lightweight, which minimizes additional stress on the bone.
Biocompatibility: Titanium is well-tolerated by the human body, reducing the risk of rejection, infection, or inflammation.
Conclusion:
The 7.0mm x 50mm Cannulated Cancellous Screw made from Titanium is an ideal choice for securing fractures in cancellous bone. Its large diameter and 16mm threaded portion provide reliable fixation, especially in areas requiring high strength. The cannulated design facilitates minimally invasive procedures, and the use of titanium ensures both durability and compatibility with bone tissue. This screw is most appropriate for shorter or less deep fractures, or where a smaller implant is needed for effective bone stabilization.
