cancellous screws
Cancellous screws represent a vital advancement in orthopedic fixation technology, specifically designed for use in bones with softer, more porous structures. These specialized medical devices feature a wider thread diameter and deeper threads compared to cortical screws, making them particularly effective in areas with trabecular bone. The distinctive design allows for optimal purchase in cancellous bone tissue, providing superior fixation strength and stability. These screws are manufactured from high-grade medical stainless steel or titanium alloys, ensuring both durability and biocompatibility. The thread design typically includes a variable pitch that enables efficient insertion while minimizing tissue damage. Cancellous screws come in various sizes and lengths to accommodate different anatomical requirements and surgical applications. They are commonly used in joint reconstruction procedures, particularly in areas such as the proximal tibia, distal femur, and calcaneus. The screws feature self-tapping capabilities that eliminate the need for pre-threading, streamlining the surgical process and reducing operating time. Advanced surface treatments may be applied to enhance osseointegration and prevent infection, while the head design allows for various driver options to improve surgical versatility.
