Large Cannulated Cancellous Screw 7.0mm X 70mm Dia. 16mm Thread Titanium

The Orthopedic Large Cannulated Cancellous Screw with the specifications 7.0mm x 70mm, 16mm thread, and Titanium material is a specialized implant used 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. This size is considered large for orthopedic screws and is suitable for use in large bones or patients with thicker bone structures. It ensures a strong grip in cancellous (spongy) bone.

70mm Length: The screw measures 70 millimeters in length, from the tip to the head. The length is typically chosen based on the size of the bone being treated and the fracture’s location.

16mm Thread: The threaded portion of the screw extends 16 millimeters. These threads help to anchor the screw securely into the cancellous (spongy) bone, where they engage the trabecular structure to provide a solid fixation.

Cannulated: The cannulated design means the screw has a hollow core, which allows a guidewire to be inserted through the screw. This facilitates accurate placement of the screw and can be used with minimal invasive techniques. It also allows for easier insertion, even in complex fractures.

Cancellous Screw: Cancellous screws are designed for use in cancellous (spongy) bone, such as the femur, tibia, or pelvis, where the bone is softer and less dense than cortical bone. These screws have larger, more spaced threads to engage with the softer, porous bone effectively.

Titanium: The screw is made from titanium, which is highly preferred in orthopedic applications due to its strength, lightweight nature, and excellent biocompatibility. Titanium’s resistance to corrosion and its ability to integrate well with human bone make it ideal for implants used in long-term bone fixation.

Typical Uses:
This screw would be used for:

Fracture Fixation: Especially in cancellous bone areas, such as in fractures of the femur, tibia, or pelvis, where the bone is softer and spongier. The screw helps to stabilize the fracture and promote healing.
Osteotomies: In procedures where bone is cut and repositioned, such as in joint realignment or correction of deformities.
Spinal Fixation: In spinal surgeries where bone stabilization is required for healing, particularly in the vertebrae.
Advantages of Cannulated Titanium Screws:
Minimally Invasive: The cannulated design allows for the screw to be inserted over a guidewire, reducing the need for large incisions, which can result in faster recovery and less trauma to surrounding tissues.
Strength and Durability: Titanium’s high strength ensures that the screw can withstand the forces applied during healing, while its lightweight nature reduces the overall burden on the bone.
Biocompatibility: Titanium is known for being compatible with human tissue, reducing the risk of rejection, inflammation, or infection.
Conclusion:
The 7.0mm x 70mm Cannulated Cancellous Screw made from Titanium is an ideal implant for securely fixing fractures in areas with cancellous bone. Its large diameter and robust thread length make it particularly suited for applications where strong bone fixation is required. Its cannulated design allows for more precise placement with minimal invasiveness, making it a preferred choice for orthopedic surgeons.
