Orthopedic Cement/Bone Cutting/Extraction Systems, Ultrasonic
Definition : Orthopedic cement/bone cutting and extraction systems designed for breaking, cutting, removing, and extracting bone fragments and/or orthopedic acrylic cement (typically polymethyl methacrylate [PMMA]) from a previously implanted prosthesis using ultrasonic energy during orthopedic procedures. These systems typically consist of a dedicated ultrasonic generator with appropriate controls, two or more handpieces (one handpiece is usually intended for cutting and removal of bone, and the other is intended for cement breakage and removal); and cement-removal probes that may be reusable or intended for single use. The systems may also include vacuum devices with appropriate suction tubes and filters to extract cement/bone fragments, irrigation devices, accessories such as slap hammers, ultrasonic powered instruments (e.g., osteotomes), and endoscopic video systems. Ultrasonic orthopedic bone and cement cutting and extraction systems are used to cut and remove bone fragments during orthopedic procedures (e.g., prosthesis implantation) and/or 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.
