Orthopedic Cement Extraction Systems
Definition : Systems designed for the removal and extraction of orthopedic acrylic cement (typically polymethyl methacrylate [PMMA]) from a previously implanted prosthesis during orthopedic procedures. These systems typically consist of dedicated powered devices, such as electric or pneumatic handpieces and burs; or ultrasonic devices, handpieces, and probes. Some systems are based in the combined use of manual instruments such as dedicated chisels, slap-hammers, hooks, manual low-speed drills, and osteotomes. The systems may also include vacuum devices with appropriate suction tubes and filters to extract cement/bone fragments, irrigation devices, and endoscopic video systems. Orthopedic cement extraction systems are used mainly to remove cement (e.g., mantle, plug) during the removal of prostheses in revision surgery (e.g., replacement) of hip, knee, and other cemented orthopedic prostheses.
