Cancellous Bone Screw: Functions, Benefits, and Surgical Applications

The cancellous bone screw is a specialized medical device designed for internal fixation of fractures and osteotomies, particularly in the treatment of cancellous or spongy bone. Its main functions include stabilizing bones during healing, providing compression to enhance the fusion process, and supporting the weight and stress of the patient. Technological features of the cancellous bone screw include a unique thread design that allows for better purchase within the bone, a variety of sizes to accommodate different anatomies, and materials that promote osseointegration. These screws are commonly used in orthopedic and spinal surgeries, where they play a crucial role in the fixation of fractures and in procedures such as hip replacements and spinal fusions.
