4.0MM CORTEX SCREW
The 4.0mm cortex screw is a type of orthopedic implant commonly used in various surgical procedures, particularly in bone fixation and reconstruction. Here's an overview of its specifications and uses:
Specification
- Material: Cortex screws are typically made from medical-grade stainless steel or titanium alloy. These materials are chosen for their biocompatibility, corrosion resistance, and mechanical strength, ensuring stability and durability in bone fixation applications.
- Diameter: The 4.0mm cortex screw refers to the diameter of the screw shaft. This diameter is standardized and chosen based on the specific bone anatomy, the size of the bone fragments being stabilized, and the mechanical requirements of the surgical procedure.
- Thread Type: Cortex screws typically have a self-tapping design with threads along the shaft. The thread pitch and depth may vary depending on the intended application and the bone density encountered during surgery. Self-tapping screws are designed to create their own thread as they are inserted into bone, minimizing the need for pre-drilling.
- Head Type: The head of the cortex screw may have various configurations, including flat, pan, or countersunk heads. The choice of head type depends on factors such as the surgical technique, the need for flush or recessed screw placement, and the preference of the surgeon.
- Length: Cortex screws come in various lengths to accommodate different bone thicknesses and surgical requirements. The length of the screw is selected based on factors such as the depth of the bone fragment being stabilized and the desired purchase within the bone.
Uses
- Bone Fixation: The primary use of cortex screws is for bone fixation in orthopedic and trauma surgeries. They are commonly used to stabilize fractures, osteotomies, and bone grafts in various anatomical locations, including the extremities, pelvis, and spine.
- Plating Systems: Cortex screws are often used in conjunction with plates and other orthopedic implants as part of internal fixation systems. They provide secure fixation of the plate to the bone, helping to maintain alignment and stability during the healing process.
- Orthopedic Trauma Surgery: Cortex screws are valuable tools in the treatment of traumatic injuries such as fractures, dislocations, and non-unions. They can be used alone or in combination with other implants to reconstruct and stabilize the injured bone, promoting healing and restoration of function.
- Bone Reconstruction: Cortex screws may be used in bone reconstruction procedures, such as osteotomies or corrective osteotomies, to realign and stabilize bone segments. They allow for precise control over bone alignment and fixation, facilitating the correction of deformities and improving skeletal alignment.
- Spinal Surgery: In spinal surgery, cortex screws may be used for various applications, including spinal fusion procedures, vertebral fracture fixation, and correction of spinal deformities. They provide stable fixation of spinal instrumentation such as rods, plates, and hooks, promoting spinal stability and fusion.
In summary, the 4.0mm cortex screw is a versatile orthopedic implant used in a wide range of surgical procedures for bone fixation and reconstruction. It offers reliable fixation, compatibility with bone tissue, and versatility in surgical applications, contributing to successful surgical outcomes in orthopedic and trauma surgery.
