Large Cannulated Cancellous Screw 7.0mm X 90mm Dia. 16mm Thread Titanium

The Orthopedic Large Cannulated Cancellous Screw 7.0mm x 90mm Dia. 16mm Thread Titanium is a specialized orthopedic screw used primarily in the fixation of bone fractures, particularly in larger bones or complex fracture cases. Below is a detailed breakdown of its features and applications:

Key Features:
7.0mm x 90mm:

7.0mm Diameter: The diameter of the screw is 7.0mm, making it a larger size typically used for larger bones such as the femur, tibia, or pelvis. The larger diameter ensures sufficient strength and stability for bone fixation, especially in cancellous (spongy) bone, which is more porous and less dense.
90mm Length: The length of the screw is 90mm, which is designed to provide adequate depth for anchoring the screw securely in the bone. This length is typically used for medium to large bone fractures or areas that require longer fixation for stabilization.
16mm Thread:

The screw has a 16mm long threaded portion. The threads play a crucial role in engaging with the bone and ensuring that the screw stays in place, especially in the cancellous bone where stability can be a concern. The full thread provides better purchase and grip, which helps prevent loosening over time.
Cannulated Design:

Cannulated means the screw has a hollow core that allows for the use of a guidewire during insertion. This design facilitates precise placement and reduces the risk of error, especially in complex surgeries. The guidewire helps the surgeon position the screw accurately, ensuring better results and reducing surgical trauma.
Titanium Material:

The screw is made of Titanium, known for its strength, lightweight properties, and biocompatibility. Titanium is highly resistant to corrosion, ensuring durability within the body, and it is non-reactive, making it ideal for long-term implantation. It also has a high strength-to-weight ratio, ensuring strong fixation without adding unnecessary weight.
Applications:
Fracture Fixation:

This screw is used for fixing fractures in larger bones, such as the femur, tibia, pelvis, and humerus, where a larger and stronger screw is necessary. It is particularly effective for fractures involving cancellous bone, where the screw’s full threads help secure it in place.
Large Bone Surgeries:

It is used in surgeries where larger bone structures need stabilization. The 7.0mm diameter provides sufficient strength for larger bone fragments, and the 90mm length ensures that the screw can be inserted deep enough to hold the bone fragments together.
Joint Fixation and Osteosynthesis:

This screw can also be used in joint fixation or osteosynthesis procedures, where the bone needs to be stabilized and aligned to heal properly. It helps secure bone fragments together, ensuring proper alignment during the healing process.
Minimally Invasive Surgery:

Thanks to the cannulated design, this screw can be used in minimally invasive surgery. The cannulated nature allows the surgeon to insert it with the help of a guidewire, ensuring precise placement without excessive dissection or damage to surrounding tissues. This approach can lead to faster recovery times and fewer complications.
Summary:
The Orthopedic Large Cannulated Cancellous Screw 7.0mm x 90mm, made from Titanium, is a robust and reliable implant designed for the fixation of larger bone fractures in orthopedic surgery. Its cannulated design with a 16mm threaded portion allows for precise placement and secure fixation, while the Titanium material provides strength, durability, and biocompatibility. This screw is especially suited for larger bones such as the femur or tibia, and is used in minimally invasive procedures to reduce recovery time and surgical trauma.
