Cannulated Cancellous Screw 6.5mm X 50mm Dia. 32mm Thread SS316L Orthopedic

The Orthopedic Cannulated Cancellous Screw with the specifications 6.5mm x 50mm, 32mm thread, and SS316L material is an implant used in orthopedic procedures, particularly for securing fractures in cancellous (spongy) bone. Here’s a detailed breakdown of its features:

Specifications Breakdown:
6.5mm Diameter: The screw has a diameter of 6.5 millimeters, which is smaller than the 7.0mm diameter screws. This size is ideal for smaller bones or fractures that do not require a larger screw for fixation, making it suitable for a wide range of orthopedic procedures.

50mm Length: The screw is 50 millimeters in length, which makes it suitable for smaller or more superficial fractures. The length is chosen based on the size and location of the fracture, as well as the bone’s anatomy.

32mm Thread: The threaded portion of the screw extends 32 millimeters. A longer thread length is beneficial for providing secure fixation in cancellous bone, where larger and more spaced-out threads are required to grip the softer, spongy structure effectively.

Cannulated: The screw is cannulated, meaning it has a hollow core. This allows for easier insertion over a guidewire, providing more precision during the procedure. The cannulated design also supports minimally invasive surgery, reducing the trauma to surrounding tissues and promoting quicker recovery.

Cancellous Screw: Designed specifically for cancellous (spongy) bone, which is more porous and softer than cortical bone. Cancellous screws typically have larger, more widely spaced threads to help grip the bone’s trabecular structure securely.

SS316L (Stainless Steel 316L): The screw is made from 316L stainless steel, a high-quality, corrosion-resistant alloy that is commonly used in medical implants. The “L” in 316L stands for “low carbon,” which makes it more resistant to corrosion and ensures better biocompatibility. This material is durable and strong enough to withstand the mechanical loads that are applied to the bone during healing.

Typical Uses:
This screw would typically be used for:

Fracture Fixation: Especially for fractures in cancellous bone, such as those in the femur, tibia, pelvis, or distal radius. The screw stabilizes the fracture and helps promote bone healing.
Osteotomies: In procedures where bone is cut and realigned for correction, such as in joint deformities.
Spinal Fixation: For stabilizing vertebrae in spinal surgeries, particularly where cancellous bone is involved.
Advantages of Cannulated Stainless Steel Screws:
Minimally Invasive: The cannulated design allows the screw to be inserted over a guidewire, enabling precise placement with minimal incision, which reduces recovery time and trauma to the surrounding tissues.
Strength and Durability: Stainless steel 316L is strong and resistant to corrosion, ensuring the screw maintains its integrity within the body over time.
Biocompatibility: SS316L is highly biocompatible, which reduces the risk of adverse reactions or infections and ensures a smooth integration with the bone.
Conclusion:
The 6.5mm x 50mm Cannulated Cancellous Screw made from SS316L stainless steel is a reliable and durable implant ideal for fractures in cancellous bone. Its smaller diameter makes it suitable for a wide range of fractures, while its 32mm threaded portion ensures a secure fit in spongy bone. The cannulated design facilitates precise placement with a guidewire and minimizes invasiveness during surgery, promoting faster recovery. The use of SS316L stainless steel ensures the screw is strong, resistant to corrosion, and biocompatible, making it an excellent choice for long-term orthopedic procedures.
