Large Cannulated Cancellous Screw 7.0mm X 80mm Dia. 16mm Thread Titanium

The Orthopedic Large Cannulated Cancellous Screw you are referring to has the following key specifications:

Specifications Breakdown:
7.0mm Diameter: The screw has a diameter of 7.0 millimeters, indicating the thickness of the screw shaft. This is on the larger side, suitable for use in patients with thicker bone structures or for larger bones such as the femur or tibia.

80mm Length: The screw measures 80 millimeters in length, which is the overall length from the head to the tip of the screw.

16mm Thread: The threaded portion of the screw extends 16 millimeters. The threads engage with the bone to provide secure fixation. The threads are designed to give better stability in cancellous (spongy) bone, where larger threads are necessary to grip effectively.

Cannulated: The screw is hollow in the center, allowing a guidewire to pass through it for better precision during insertion. This feature helps in achieving accurate placement, especially in delicate or complex fractures. The hollow design also allows for a more minimally invasive procedure, as it can be inserted with less tissue disruption.

Cancellous Screw: Designed for use in cancellous bone (also known as spongy or trabecular bone), which has a porous structure. The screw is specifically designed to grip this type of bone, providing greater stability and preventing slippage.

Titanium: The screw is made from titanium, a material known for its strength, light weight, and exceptional biocompatibility. Titanium is corrosion-resistant and integrates well with bone tissue, making it ideal for use in orthopedic procedures.

Typical Uses:
This screw is commonly used in orthopedic surgeries to secure fractured bones, particularly in areas with cancellous bone, such as:

Fracture fixation: Especially in spongy bone areas like the femur, tibia, or pelvis.
Osteotomies: When bone cutting is done to realign or reshape the bone.
Spinal surgeries: For stabilization of vertebrae, often in conjunction with other implants like rods or plates.
The 80mm length may be chosen depending on the bone size and fracture location, and the larger diameter (7.0mm) ensures a solid grip, even in more challenging cases.

Advantages of Cannulated Titanium Screws:
Minimally Invasive: The cannulated design allows for the use of a guidewire, which helps to reduce the need for large incisions and reduces recovery time.
High Biocompatibility: Titanium is known for being highly compatible with human bone tissue, reducing the risk of infection and rejection.
Durability and Strength: Titanium’s strength ensures that the screw will hold under the mechanical loads and stresses placed on the bone during healing.
This type of screw is designed to provide secure and reliable fixation for fractures, ensuring faster and more effective healing.
