4 mm Cancellous Screw

The 4 mm Cancellous Screw is a specialized medical device designed for orthopedic applications. It is a screw with a diameter of 4 mm , constructed from high-quality stainless steel or titanium alloy. This screw is specifically intended for use in cancellous bone.
The 4 mm Cancellous Screw features a cancellous thread design, providing excellent grip and stability within cancellous bone. It is self-tapping, allowing for easy insertion without the need for pre-drilling. The screw is available in various lengths to accommodate different surgical needs and patient anatomies.
Each 4 mm Cancellous Screw is individually packaged in a sterile manner to ensure safety and prevent contamination. It is an essential tool used by orthopedic surgeons during fracture fixation, bone grafting, and corrective osteotomy procedures.

Fracture Fixation: The 4 mm Cancellous Screw is frequently employed in the fixation of fractures involving cancellous bone. It provides stability and helps promote proper healing by securely anchoring bone fragments together.
Bone Grafting: During bone grafting procedures, the 4 mm Cancellous Screw is often utilized to secure bone grafts in place. This ensures stability and facilitates the integration and regeneration of the graft.
Osteotomies: In corrective osteotomy surgeries, the 4 mm Cancellous Screw can be used to realign bones and maintain the desired position while the bone heals. It aids in the stabilization of the osteotomy site.

Joint Fusions: When fusing joints, such as in arthrodesis procedures, the 4 mm Cancellous Screw may be employed to immobilize and stabilize the joint. It facilitates the fusion process by holding the bones securely together.
Fixation of Bone Fragments:This screw can also be used for fixation purposes in cases where small bone fragments need to be stabilized, such as in avulsion fractures or bone chip fixation.

Diameter:4 mm This refers to the diameter of the screw shaft itself. It is the primary dimension that determines the size of the screw.
Material:The screw is constructed from high-quality stainless steel (LVM) or titanium alloy.Stainless steel (LVM) provides strength and corrosion resistance. Titanium alloy offers high strength, biocompatibility, and low density.
Thread Design: The screw features a specialized cancellous thread pattern designed to optimize engagement and fixation in cancellous bone. The cancellous threads are spaced to provide effective grip and stability.

Self-Tapping: The screw is designed with a self-tapping feature, allowing it to penetrate the bone without the need for pre-drilling. This feature helps simplify and expedite the surgical procedure.
Head Options:The screw may have different head options, such as a hexagonal head or a slotted head. The choice of head design depends on the surgeon's preference and compatibility with surgical instrumentation.
Length Options:The screw is available in various lengths to accommodate different surgical needs and patient anatomies. The specific length chosen depends on factors such as the bone structure and the intended application.

Sterile Packaging: Each screw is individually packaged in a sterile manner to ensure safety and minimize the risk of contamination.Sterile packaging helps maintain the integrity of the screw until it is used in the surgical procedure.
