pedicle screw types
Pedicle screws are medical devices used primarily in spinal surgery, designed to provide stability and promote fusion between vertebrae. These screws are inserted into the pedicle of the vertebrae, and their main functions include immobilizing the spine, correcting deformities, and supporting the vertebral column during the healing process. Technological features of pedicle screws encompass a variety of materials such as titanium or stainless steel, and designs that range from solid to cannulated, allowing for minimally invasive surgery. Thread patterns may differ to accommodate various bone densities. These screws find application in treating conditions like spinal fractures, spinal deformities, and certain types of cancer affecting the spine. Their versatility makes them an essential tool in a surgeon's arsenal, providing a strong foundation for various spinal procedures.
