Orthopedic Cement Extraction Systems, Ultrasonic 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 ultrasonic energy during orthopedic procedures. These systems typically consist of a dedicated ultrasonic generator with appropriate controls, one or more ultrasound handpieces, and cement-removal probes that may be reusable or intended for single use. The systems may also include irrigation devices, vacuum devices with appropriate suction tubes and filters to extract cement/bone fragments, accessories such as slap hammers, and endoscopic video systems. Ultrasonic 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.
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.
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.
