Cannulated Cancellous Screw 6.5mm x 50mm 16mm Thread Orthopedic SS316L

The Cannulated Cancellous Screw 6.5mm x 50mm 16mm Thread Orthopedic SS316L is another type of orthopedic screw designed for fixation of fractures or bone-related issues, but with specific features and specifications. Let’s break down the description:

Key Features:
6.5mm x 50mm:

6.5mm: The diameter of the screw. This is a larger diameter than the 4.5mm screw, making it suitable for larger bones or fractures where greater strength is needed.
50mm: The length of the screw, providing enough length for fixation in bone areas with sufficient depth.
16mm Thread:

The 16mm thread refers to the length of the threaded portion of the screw. The thread helps anchor the screw more securely into the bone, particularly useful in the cancellous bone where the structure is porous and softer.
Cannulated:

The screw has a hollow core, or cannula, which enables the use of a guidewire during insertion. This helps ensure precise placement, minimizing the risk of damaging surrounding tissues or misplacement of the screw. The cannulated design is particularly beneficial for minimally invasive surgery.
Orthopedic SS316L:

SS316L refers to Stainless Steel 316L, a high-quality, corrosion-resistant material often used in orthopedic implants. The “L” in the material designation stands for “Low Carbon,” which reduces the risk of carbide precipitation and improves the material’s resistance to corrosion and bio-integration. SS316L is known for its strength, durability, and compatibility with the human body, making it suitable for long-term use in medical implants.
Applications:
Fracture fixation: The Cannulated Cancellous Screw 6.5mm x 50mm is commonly used in the fixation of fractures, particularly in larger bones or in situations where a stronger screw is necessary for secure bone fixation.

Large bone fractures: The larger diameter (6.5mm) makes it suitable for fractures in bones like the femur, tibia, or pelvis where cancellous bone is prevalent. The larger screw size provides greater holding strength, which is needed for optimal stabilization.

Minimally invasive surgery: Due to its cannulated design, this screw can be inserted using a guidewire, allowing for more precise placement and minimizing surgical trauma. This is beneficial in reducing recovery time and complications.

Joint surgeries and osteosynthesis: It is used for surgeries involving joint repair or osteosynthesis (bone union) after fractures, typically in the hip, femur, and tibia, among other locations.

Summary:
This screw, made of SS316L stainless steel, offers strength, durability, and resistance to corrosion, making it ideal for orthopedic procedures. Its cannulated design with a 16mm threaded portion allows for precise placement, especially when using a guidewire, and is typically used in the fixation of larger bone fractures.
