Orthopedic Cement Extraction Systems, Manual
Definition : Orthopedic cement extraction systems designed for the breakage, removal, and extraction of orthopedic acrylic cement (typically polymethyl methacrylate [PMMA]) from a previously implanted prosthesis using a combination of manual instruments during orthopedic procedures. These systems typically include disposable (i.e., single use) instruments such as cannulas, tubes, and syringes and reusable dedicated chisels, slap-hammers, hooks, low-speed manual drills, and osteotomes; some systems mix new bone cement with the old cement and then extract the mixture. The systems may also include vacuum devices with appropriate suction tubes and filters to extract cement/bone fragments, irrigation devices, and endoscopic video systems. Manual orthopedic cement extraction systems are used mainly to remove cement (e.g., mantle, plug) during the removal of old prostheses in revision surgery (e.g., replacement) of hip, knee, and other cemented orthopedic prostheses.
