2.7/3.5/4.5mm Cortical Screw Full-threaded: A Comprehensive Guide

The 2.7/3.5/4.5 mm Cortical Screw Full-threaded is a highly versatile orthopedic implant designed for fixation in cortical bone. These screws come in different sizes to cater to various fracture types and bone diameters, making them essential tools in orthopedic surgeries. They are most commonly used for the stabilization of fractures, osteotomies, and other bone deformities that require strong and reliable fixation. This guide will delve into the features, advantages, risks, and treatment applications of these screws, providing valuable insight for medical professionals, students, and patients alike.

What is 2.7/3.5/4.5mm Cortical Screw Full-threaded？

The Cortical Screw Full-threaded is a type of orthopedic screw that is fully threaded along its length, designed specifically for use in the cortical bone, the dense outer layer of bone. The sizes 2.7 mm, 3.5 mm, and 4.5 mm correspond to the diameter of the screw, allowing for a wide range of applications based on bone size and fracture type.

2.7 mm: Ideal for smaller bones or pediatric fractures.

3.5 mm: The most commonly used size in adult orthopedic surgeries, suitable for medium-sized bones.

4.5 mm: Larger screws used for robust fixation in larger bones, such as the femur, tibia, and humerus.

The full-threaded design enhances the screw's ability to secure bone fragments by providing a strong hold along its entire length, ensuring the stabilization of bone fragments until healing occurs.

2.7/3.5/4.5mm Cortical Screw Full-threaded Features

Full Threading

The screw is fully threaded, providing excellent grip and compression throughout the bone, which enhances fracture stabilization and promotes faster healing.

Material Composition

Typically made from titanium or stainless steel, both materials offer biocompatibility, strength, and resistance to corrosion, making them ideal for long-term use within the human body.

Precision Machining

These screws are manufactured with high precision, ensuring smooth insertion and minimizing the risk of damage to surrounding tissues.

Self-Tapping Design

The screw's self-tapping nature eliminates the need for pre-tapping the bone, which saves time during surgery and reduces the risk of errors in screw placement.

Variable Lengths

Available in various lengths, the screws can be tailored to fit different fracture sites and anatomical structures.

Thread Pitch

The screw's thread pitch is optimized to balance fixation strength and ease of insertion, reducing the risk of screw loosening postoperatively.

2.7/3.5/4.5mm Cortical Screw Full-threaded Advantages

Enhanced Fracture Stability

The full-threaded design ensures that the screw provides maximum compression at the fracture site, which is essential for promoting proper bone healing and minimizing the risk of nonunion or malunion.

Minimal Surgical Trauma

These screws are designed for easy insertion, with the self-tapping design allowing for quicker placement and minimal damage to the surrounding bone and tissue.

Versatility

Available in different sizes (2.7, 3.5, and 4.5 mm), these screws can be used across various bone types and sizes, making them suitable for both small and large bones.

High Biocompatibility

Made from materials like titanium or stainless steel, these screws are biocompatible, reducing the likelihood of foreign body reactions and ensuring long-term stability within the body.

Reduced Infection Risk

With a smooth and polished surface, these screws have reduced friction during insertion, lowering the risk of infection or irritation in surrounding tissues.

Improved Postoperative Outcomes

Due to their strong fixation capabilities, these screws contribute to better postoperative results, reducing the likelihood of secondary surgeries or implant failure.

2.7/3.5/4.5mm Cortical Screw Full-threaded Treatment of Fracture Types

Fractures of the Long Bones

Such as fractures in the femur, tibia, and humerus, where strong, reliable fixation is required.

Fractures of the Spine

When used in spinal fusion procedures, these screws help stabilize vertebrae and facilitate the healing process.

Distal Radius and Ulna Fractures

Especially in older adults, the 3.5 mm or 4.5 mm Cortical Screws are commonly used to secure the fragments and promote healing.

Pelvic Fractures

In cases of pelvic fractures, these screws provide the necessary stabilization to the bony structures, ensuring that healing occurs correctly.

Metatarsal and Phalangeal Fractures 

Smaller sizes like the 2.7 mm Cortical Screws are used in hand and foot surgeries to stabilize small bone fractures.

Fractures in Osteoporotic Bone

The 3.5 mm and 4.5 mm screws can be used in patients with weakened bones, offering better fixation than other screw types and reducing the risk of screw loosening.

Risks of 2.7/3.5/4.5mm Cortical Screw Full-threaded Surgery

Infection

As with any surgical implant, there is a risk of infection at the incision site or around the screw. Proper sterile techniques and postoperative care are crucial to minimize this risk.

Screw Loosening or Migration

In cases of poor bone quality (such as in osteoporotic patients), the screw may loosen or migrate over time, which can result in fracture displacement and the need for revision surgery.

Nerve or Vascular Injury

Incorrect placement or improper surgical technique may lead to damage to nearby nerves or blood vessels, especially in delicate anatomical regions.

Fracture Nonunion or Malunion

If the screw does not achieve optimal compression or alignment of the fracture fragments, there is a risk of delayed union, nonunion, or malunion, which could require additional surgery.

Hardware Failure

While rare, screws can fail due to material fatigue or improper placement, leading to breakage or deformation.

Postoperative Complications

Issues such as swelling, hematoma formation, or delayed healing can occur, depending on the patient's overall health and bone condition.

2.7/3.5/4.5mm Cortical Screw Full-threaded Future Marke

Aging Population

As the global population ages, there will be an increased incidence of bone fractures, driving demand for high-quality screws for fracture fixation.

Technological Advancements

Continuous innovation in materials, such as the development of bioabsorbable screws and improvements in screw design, will make the Cortical Screw Full-threaded more efficient and adaptable.

Minimally Invasive Surgical Techniques

Surgeons are increasingly adopting minimally invasive techniques, and the Cortical Screw Full-threaded is well-suited for these approaches, especially with its self-tapping feature.

Rising Orthopedic Surgery Volumes

As orthopedic surgery volumes rise, particularly in trauma and joint replacement surgeries, the demand for these screws will increase.

Global Healthcare Expansion

With the improvement of healthcare infrastructure in developing countries, the use of advanced orthopedic implants like the Cortical Screw Full-threaded will likely increase.

Summary

The 2.7/3.5/4.5 mm Cortical Screw Full-threaded is a versatile, reliable, and efficient solution for the fixation of fractures in cortical bone. Available in various sizes, these screws cater to a wide range of fracture types, from small phalangeal fractures to large, complex long bone fractures. With their full-threaded design, biocompatible materials, and self-tapping feature, they provide excellent fracture stability and promote rapid recovery. While there are inherent risks associated with their use, such as infection and screw loosening, the advantages of these screws far outweigh the potential drawbacks. As the demand for orthopedic implants increases, the future of the Cortical Screw Full-threaded remains promising, with advancements in technology and growing healthcare needs driving continued market growth.
